An effective 3D printing method can be a significant difference between making products of great quality or good quality. A solution is there, and it is a proven technique to create stunning-looking products. UV curing station or box is the answer.

Speaking about the UV curing method, it is referred to as the ultraviolet curing method and is widely used as a post-processing method in LCD 3D printing.  It is the photochemical process where a powerful UV light source is used to instantly cure adhesives, inks, and coatings. This offers a lot of advantages compared to the traditional curing and drying methods. Some of the significant benefits of using a UV curing box are:

  • A significant reduction in the rate of rejected products
  • Increase in production speeds
  • Facilitate super bonding in the products
  • Improvement in scratch and solvent resistance

Using UV Curing

Introduced during the 60s, a UV curing chamber for 3D printing is now widely available in the market, and one can get a machine under the budget. These machines are commonly used in different industries such as glass decorating, plastic decorating, electronics, jewelry, graphics arts, automotive and more.

As a multi-billion-dollar industry, this particular method covers around 5 percent of the global industrial coating market. It can be said that the UV resin curing method has displaced the water-based and solvent-based thermal drying process as this process is very fast and effective.

How does the process work?

Adding post-curing to the 3D printing process, especially in stereolithography, can help you get the best quality products, which can significantly enhance performance and strength. This is where you can use a UV light curing box. All the UV curing system works through a straightforward process.

In general, UV curing uses light through a photochemical reaction. The process doesn’t use heat. Liquid monomers and oligomers are combined with some photo-initiators before exposing to the UV energy source. After a few seconds or minutes, the products to be cured will harden instantly.

Exploring some benefits of using UV curing in manufacturing

The benefit of UV resin curing in different manufacturing applications is constantly growing. Do you know that most of the 3D models or action figures created using LCD 3D printers are cured using a UV resin curing chamber? Most of the manufacturing processes use UV light sources for the items you encounter regularly.

Some essential items, such as bottles cap, food cans, soda cans, lids on jars, plastic cups, luxury vinyl tile flooring, pet food bags, magazine covers, car headlights, and more, have been cure under this process.

Most manufacturers have understood the significant benefits of utilizing the UV curing method in their manufacturing process. UV curing is a green technology as UV chemistries that include adhesives, coatings, and inks are 100 solids, and they don’t release VOCs into the atmosphere. If you look at other technologies, for example, the convention thermal drying process, these processes produce VOCs and HAPs- Hazardous Air Pollutants.

  • UV curing can significantly improve the physical properties of the product

Producers generally consider using a UV curing system for printing as the process dramatically improves gloss as well as ensures a better level of resistance against scratches and abrasion. On the other hand, such systems offer a greater level of strength, chemical resistance, adhesion, elasticity, and this can also enhance the products’ resistance.

  • Faster production capacity

The production process that requires less space will facilitate a better production speed. As this method involves little labor, you will get more resources to improve your overall production capacity. With the best UV curing chamber, you will be able to witness higher throughput, fewer hours of downtime, and better utilization of the machine. All these things will significantly improve the capacity of your plant. So, get one now and increase productivity.

  • Lowers the work in process

If you want to lower the manufacturing cycle time, then it’s time to deploy a UV light curing box in your production process. By significantly lowering the work-in-progress, UV resin curing systems will help you save capital while increasing the cash flow.

As the resin-made product will never cure unless they are exposed to UV light, you can leave those products overnight, knowing that the coating or ink will not dry. Besides, unused resins can be left in the machine. This can be very advantageous for you if you are working in graphic arts printing or using your UV curing box for plastic decorating machines.

  • UV curing is proved to be effective in reducing scrap.

The process of UV curing can be completed within a few seconds. That means you can easily spot any curing problems immediately. Therefore, with such curing systems, you will enjoy a massive level of reduction in the amount of scrap produced.

For example, the standard adhesive can take many days to cure. After that, you will have to carry out quality control testing. However, during this process, you may end up with a lot of scrap parts.

In most UV curing systems, there are various quality control procedures that you can follow to carefully inspect coating, ink, and adhesive application much before starting the UV curing process.

After knowing all these benefits, it can be said that getting a UV curing machine for 3D printing can be a great idea. But the question is how to choose the right UV curing chamber? Well, to help you out, we have written down some important information. Going through the information, you will be able to pick a suitable machine for you. Have a look.

1.1, The principle of 3D printer printing resin

Speaking about resin 3D printing, this is considered as an umbrella term under the 3D printing technologies where the UV rays cure the resin or liquid photopolymers. It cures the material layer by layer and turns that into solid 3D models.

Well, resin 3D printing is not the official title, but as the machine works with resin, it will be an easy way to understand this printing technology. In some cases, VAT polymerization and Stereolithography printing terms are used.

The factors that define resin 3D printing

  • They utilize the principle of photopolymerization to make the objects.
  • They operate based on the codes. The printing machine creates the codes from the uploaded digital model.
  • As a printing material, the resin 3D printing uses UV or photopolymer resin.
  • The printing material is stored in a resin tank.

One of the primary principles of 3D printer printing resin is photopolymerization. In simple words, this is a chemical reaction of resin where the properties of resin change when exposed to the UV light source. The scientific name for such liquids or resins is photopolymers or light-activated resins.

There are various types of photopolymerization reactions. Besides, the outcomes also vary. However, the one that is widely used in the field of 3D printing is solidifying. Under this process, the liquid resin turns solid under the UV light source. Well, the sources of light can be different, for example, projectors, LCD panels, lasers, and more.

Exploring some major advantages of resin 3D printing

  • Great details- Under this printing, liquid photopolymers are loaded into the printer. These resins are much easier to shape, and you can easily create complicated geometries. This may not be possible in the case of filaments.
  • Super smooth surface- Even though layer lines will be there in the prints, but they will very small and invisible.
  • Different types of materials- You will find different types of resins that can cover various applications and requirements. Each type of photopolymer resin includes different working components needed for the reactions as well as additives like dyes and functional supplements.
  • Support doesn’t affect the surface- The tank is filled with resin across the perimeter. Suppose there is a few overhangs, they can be attached to parts during the curing process.
  • Faster production- If you compare this with other types of prototyping techniques, you will find that resin 3D printing is very fast, and advanced machines can print high-quality models at a faster rate.
  • Lower costs- For different applications, such as custom dental devices, master molds for jewelry, and prototypes, resin 3D printing can save the budget.
  • The models will be waterproof- Compared to filament printing materials, photopolymers come out waterproof as well as solid. The models will not absorb moisture and can be used for different water-tight applications.

Understanding the technology- It is all about UV lights

The primary technology behind the resin 3D prints is stereolithography. Here is a complete explanation of how the Stereolithography process works.

  • First, the roller of the printer applies a thin layer of liquid polymer. As the resin is in liquid form, it will spread out over the printing platform properly, ensuring that each layer has a perfect level of consistent thickness.
  • The liquid resin is UV sensitive. When stuck by the UV laser produced by the 3D printer, the resin begins to change from a liquid state to a solid. In general, the UV laser source creates the outlines of the model to be printed onto the resin layer. And the UV rays harden the parts. The remaining resins that are not touched by the light source will be in liquid form.
  • This process is repeated until the model is completed. Once the printing process is done, and the entire model has been printed, the build platform will be raised out of the resin tank. This will make the excess liquid flow away. Those resins can be reused later for making other 3D models.
  • Once done, remove the printed model and complete the other process, such as removing support structure, smoothen the surfaces, and more manually.

Understanding the post-processing

If you compared it to other 3D printing techniques, you would find that resin 3D printing always needs post-processing. Some of the significant post-processing methods are:

  • Washing – It is used to remove uncured resin leftovers. For this, the 3D-printed model is put into water or alcohol and then left dry on the paper towels.
  • Support removal- This method includes the removal of supporting structures from the 3D-printed object. Based on the models you are making, the printing process will support and hold things properly. In general, such support structures are very easy to remove. However, the process is a little time-consuming.
  • UV curing – When the parts finish printing, they remain on the print bed in an unactive or green state. That means even though the parts have attained their final form, they have not attained the polymerization reaction. Through the UV curing using a UV resin curing station,you can activate all the mechanical properties of the model. The UV rays will strengthen as well as solidify the model.

Apart from these post-processing steps, resin 3D printing can include some other types of post-processing. For example:

  • Sanding – The post-processing method removes taps from areas touched by supports and then properly smooths the surface. For this, you can use wet sanding or dry sanding tools. With wet sanding, you can get a smoother surface. This process can be carried out after the UV curing process.
  • Patching the escape holes- To lower the photopolymer’s cost, some models come with a hollow design. So, these models can have escape holes to release resin. However, they will not look aesthetically pleasing. Under the patching process, these holes are manually closed using resin.
  • Finishing- This post-processing method includes covering the 3D-printed parts using special compositions in order to strengthen the parts and eliminate any imperfections. Some manufacturers go for priming. This is generally done before UV curing as a coating can help to prevent material from over curing under UV light.
  • Painting and polishing- Utilizing different special compounds, polishing and painting are done to attain a clear and smooth surface. If you want a glass-clear look, go for this method.

All the post-processing methods can be carried out manually or using special devices. Post-curing is essential for different resins. After the post-curing, resins can attain the best functional properties. So, if you are involved in resin 3D printing, using the best resin printer curing station will offer you a lot of benefits.

1.2, Analysis of the types of 3D printed resins

3D printing has the ability to quickly convert digital design files into physical objects utilizing CAD-Computer Aided Manufacturing. These machines can process different types of resins, and some of the most popular resins are:

  • Standard rigid resin

This type of resin is used for artwork, handmade model making, jewelry model making, and various DIYs. Such resins have high precision, and the models can be clear details and smooth surfaces. With this, you can enjoy stable printing with low viscosity, and standard rigid produces low odor.

  • ABS resin

Introduction to the UV curing chamber (Arpit)

UV Curing is an approach by which the Ultra Violet lights start a photochemical reaction. This reaction helps you generate a network of cross-linked network of polymers that enables you to increase the durability of the element you are using it in. One such essential process where you adapt UV curing is 3D printing. When it comes to 3D printing, the UV curing Chamber is the part that initiates the UV Curing process. 

The UV Curing machine makes uses of the Ultra-violet ray or the lights to dry up the printed material. Every 3D printing machine you know uses the cured ink. However, these cure inks do not get evenly distributed in the printed material. In such cases, the UV Curing station in the curing machine initiates the process of curing to distribute the ink evenly on the surface of the printing material. However, another preeminent significance of the UV curing box is it even makes the printing more durable.

When the ultraviolet lights in the UV resin Curing chamber fall on the inks, it instantly dries up the ink and eliminates the chances of spreading out of the ink. The UV curing was got initially developed for the drying of nail polishes. However, later it rapidly expanded in the commercial industries like printing. The adaptation of the UV curing process in 3D printing has always been a profitable investment. This is because; when the UV lights cure the printed ink instantly, the wet ink gets no chance to spread out. That is why it offers you much more detailed 3D printing.

Besides, the most satisfying significance of the UV curing chamber is it is weather resistant. That curing process makes your 3D printing resistible to any weather. And it also achieves an enhanced resistivity to the fading. Further, the UV curing process in the UV curing chamber is also environment-friendly. It produces only a few VOC’s Odor that is not harmful to the environment. 

The UV curing chamber delivers consistent UV lighting at 360o. This helps you cure your prints that come with Photopolymer resins. Every UV curing chamber these days comes with a 360o turntable. This turntable starts rotating when the curing process starts. This, as a result, offers you a more steady and consistent output. The curing Chamber also has a reflective mirror inside it that reflects the UV light for efficient 3D printing.

There are even some UV curing chambers that use mercury lamps. These mercury lamps in the curing Chamber employ UV LEDs. The UV LEDs are the light source that doesn’t produce any Ozone. The curing Chamber in the modern-day printing machine focuses on being more environment-friendly for sustainable development. 

2.1, The Principle of resin curing machine

The Resin curing machine works on the principle of photopolymerization of resin. In this method of instant prototyping, the 3D printer uses certain UV lights in its curing Chamber to heat and cure the resins. The UV has the quality to cure the resins under UV light or heat. The resins are known as photosensitive resins. Based on the file, or the print that you enter, the resins cure them layer by layer to obtain a highly efficient object.

The working of resin curing machine 

In 3D printing, you must be aware of stereolithography. This is an additive printing approach that is more popularly known as Resin 3D printing. The printing prototype uses resins to obtain higher and maximum accuracy in the manufacturing object. Further, the resins also deliver a fine and smooth finish on the surface. However, as this printing approach uses liquid epoxy resins to print, it needs instant drying and curing to get a durable print and in-depth detail. This is where the resin-curing 3D printing machines come into use.   

These machines come with the same principle. It uses a light source, primarily UV light, to offer rapid drying to the liquid epoxy. After providing the precise UV heating, the resins then become hardened plastics.

The resin curing machine gets equipped with a curing chamber. This Chamber contains the liquid epoxy resins to cure the print. The Chamber also has a turntable that rotates 360o to offer you precise curing. The turntable in the curing machines also has reflective mirrors to offer an even quicker drying of the resins.

The main stages of Resin curing

There are different layers in resin 3D printing that makes the complete outcome. So, there will be different stages of resin curing as well. in the first stage, the ultraviolet ray scans the complete surface of the resin in the 3D printing object. Further, in the next step, the resins then get converted to a solid polymer by using the Ultra Violet light and heat. After completing the first layer, then the UV heat cures the subsequent layers.

Once the curing process completes, then the object gets removed from the UV curing chamber. 

Stages of the curing process 

  • Laser beams or the UV rays scan the surface of the resins
  • The platform gets lowered where the UV heat can reach up to all the portions 
  • Then the laser polymerizes the following layers

2.2, Why does the resin after 3D printing need to be cured by a UV curing machine?

When you are complete with your 3D printing from a resin printer, you can witness that the print is still soft and sticky. This is because; the use of liquid epoxy resin doesn’t dry up quickly. In such cases, the print that you are getting to obtain needs either direct sun rays or UV rays to get hardened. 

However, every business wants to deliver its services in the shortest time possible in the commercial industry. They use a UV curing machine to get rapid results. Further, the process of curing the resins after 3D printing is essential as it makes your print look smoother and eliminates any reactions. The most vital reasons that business uses curing process is for achieving the in-depth detail.

The resin itself is famous for offering detail printing. But if it doesn’t dry up rapidly, you will lose the details that you have obtained. This is why you need to cure resins after you are complete with your printing.

The curing of resins will also make your 3D printing exceptionally durable. However, you should also make sure that you are not over-curing the object. Over curing your 3D printing can make it more complex and more brittle that won’t look precise. You may also lose your details.

The scientific reason why does you need to cure the resins after the 3D printing?

When you are printing any 3D object using the epoxy polymer, the printing process includes the cross-linking of the polymers. However, after the cross-linking of the polymers, the polymers must get adequately align with each other.

The proper alignment only will offer you the best outcome. It is much similar to tempering the steel. After getting its shape at a temperature, the steel then cools so that it can achieve more tensile strength. Similarly, in 3D printing, you need to cure the resins to achieve tensile and flexural strength. 

The post-curing process is essential in 3D printing because achieving strength at room temperature takes a lot of time and can ruin the shape of 3D printing. However, with the help of UV curing, you can get the maximum durability and adequately align the polymers.

2.3, What are the benefits of the UV curing chamber?

There are several advantages that you get from the use of curing Chamber. However, one of the primary advantages that you are calling from the UV curing chamber is faster material processing. Yes! Every business would want to deliver their materials in a competitive time.

Generally, people are confused about the applications of UV light and associate it with the sun and skin cancer. On the other hand, people should also note that ultraviolet light is not always harmful and presents many promising results when used with different technologies.

One of the common applications of ultraviolet light is disinfection and sterilization in different hospitals.

With a UV resin curing chamber, creators could develop completely new pieces of equipment according to a particular prototype. UV curing gives the most important benefit of adhesive bonding of UV resin for attaching parts together.

In addition, it also ensures the proper design of sites that are inaccessible. The applications of UV curing depend on inks, adhesives, and coatings which are generally 100% solids and do not emit volatile organic compounds or VOCs. Furthermore, UV cured coatings are also gaining prominent levels of recognition for their better physical properties in comparison to thermally dried coatings.

All of these implications point out the necessity of learning about the applications of UV curing machine in different cases. Here is an outline of the different ways in which UV curing is transforming the domain of manufacturing.

3.1 Jewelry

Resins are one of the first things that you should take into account when discussing UV curing. UV resin curing box is a helpful instrument to get some of your favorite jewelry designs developed in physical form. The UV resin used in the case of jewelry is derived from natural elements or artificially created resins. The resin has the unique property of insolubility with water, thereby implying higher viscosity.

The viscosity of the UV resin is one of the foremost reasons for using them in UV curing to produce exceptional jewelry designs. Interestingly, the resin for jewelry is an advanced variant that can be easily cured within a short time period by utilizing ultraviolet radiation.

The different types of jewelry castings that you can use with a resin curing chamber with UV light indicate the foremost advantage of UV curing, i.e., comprehensiveness. It is possible to use UV curing for modifying resin design patterns with different types of jewelry such as rings, tie pins, earrings, bracelets, and cufflinks.

The best thing about the applications of UV curing for manufacturing jewelry is the easy accessibility of UV resins. Furthermore, the cost of UV resins for jewelry is also very reasonable, thereby allowing flexibility for all designers and manufacturers.

UV resin curing chamber is compatible with UV resin that is available in different sizes of bottles. The large bottles don’t cost much, and you also have the flexibility of choosing the size according to your project. The effectiveness of the machine matters significantly for UV curing in the case of jewelry. Users need to buy suitable flashlights, lamps, or nail curing lights with UV resin and take the effectiveness of the machines into account. Most probably, a 4-watt UV lamp could work well and give your curing for jewelry within two to three minutes.

UV curing applications for jewelry also include references to the simplicity of choosing the type of resins. The hard and soft UV resins are suitable for different types of outcomes in jewelry manufacturing. For example, the hard resin is suitable for mold applications or bezel filling in jewelry. On the other hand, soft resin, as the name implies, is very flexible in nature and can utilize a wide assortment of ornate designs.

3.2 Dental

UV light curing box also finds applications in the field of dentistry. The growth in demand for curing light has been effectively observed with the rising popularity of resin composites as well as light-cured materials. You would find the dental curing light as the foremost ingredient in dental practice routines. Earlier designs of UV curing lights have given way to LED and halogen lights becoming the common alternative. Many people have doubts about what is the exact application of the ‘blue light’ used by dentists. It is a curing light and helps in the polymerization of resin-based composites. Basically, a UV curing machine helps in solidifying the fillings inserted in teeth by dentists.

The use of UV curing in dental care started way back in 1969. The first light-curing resin composites made a mark in restorative dentistry and gained attention. The UV light polymerizing devices helped in the photopolymerization of dental composites and started a new benchmark in dental care.

The arrival of light-curing was a promising innovation at par with the use of adhesives for bonding composites to the enamel. However, problems with the initial UV curing apparatus in dental care primarily came from the shorter wavelengths of UV radiation energy. Subsequently, UV light curing machines in dental care applications found new design improvements with the introduction of functionalities such as QTH or quartz-halogen bulbs and PAC or plasma-arc curing.

However, the most prominent change in the design of UV curing machine in the field of dental applications came in the later part of the 1990s. The arrival of LEDs served as a game-changing intervention as it helped in offering light in the blue-visible spectrum.

Since then, LED UV curing machine has become a reliable alternative for dental treatments involving the use of light-cured composites. The interesting aspect about modern UV light curing machines in dental care also refers to the evolving designs of the machines.

UV light curing machines for dentists come with a selection of different curing tips. As a result, they can help in reaching different areas of the patient’s mouth easily without causing any discomfort. At the same time, the modern advancements in the use of UV curing for dental composite treatments also give the flexibility for addressing various restoration sizes.

The instruments for UV curing in dental care also provide the ease of calibrating the curing light to the selected frequency. This can be considerably helpful for long-term prospects of using UV curing in dentistry.

3.3 Anime Figure

The next most crucial area of application for a 3D printer curing station is evident in the production of anime figures. Wherever you look, three-dimensional or 3D printing, also referred to as additive manufacturing, is always a notable topic of discussion. It has found applications in the manufacturing of new machines, medical devices, and clothing, as well as action figures.

Now, this is where you can find the most promising application of UV curing for 3D printing. UV curing is important for a critical subset of additive manufacturing, stereolithography, which involves the creation of a computer-designed object into a solid 3D figure. The faster prototyping with reliable dimensional accuracy through UV curing provides many advantages in creating anime figures.

UV curing can help in creating almost any 3D shape alongside manufacturing multiple copies of figures on a single platform. The interesting factor about the use of UV curing in creating anime figures is the ability to scale the size of the models according to requirements. The application of a resin 3D printer curing station could show you how UV curing is helpful for manufacturing anime figures.

The process begins with a 3D computer image that is converted into a ‘sliced up’ version, including various thin layers. Inside the machine, a solid-state laser would then draw the layers included in the file on the platform. The platform, suspended in a vat of UV curing resin, serves as an important foundation for creating anime figures.

UV curing treatment would then involve contact of the UV laser beam with the resin composites. Subsequently, it would lead to activation of photo-initiators and help in immediately curing the resin composite to a solid polymer state. The platform then comes down slowly and allows the UV resin to flow over the solid polymer layer.

Subsequently, the laser would repeat the drawing process and build the 3D impression of the object according to each layer before completing the final product. It is important to note that the quality of anime figures created with UV curing machines depends a lot on the selection of UV curing resin.

The use of UV curing for creating anime figures has given the adequate foundation for ensuring functional testing or prototyping. When you can create identical 3D figurines based on the designs on your computer, it is reasonable to use the technology for a greater purpose.          

 3.4, Crafts

As discussed above, 3D printing is popularly known as additive manufacturing, and in this technology, the machine creates 3D objects using resins and filaments. Based on the type of machines you are using, you can create very thin layers, and that’s why 3D printing is quite popular in craft making. Making crafts, especially crafts with complex patterns and designs can be very challenging and time taking. However, the introduction of 3D printers and a resin 3d printer curing station has made the entire craft-making process a lot faster and easier.

There is no need to create objects from blocks or other materials through the hand-carving process. Using 3d printer, you can get the object done within a few minutes. The 3D printer layers the filaments or resins until the machine finishes the model making. Instead of crafting the design by hand, you can use 3D modeling software to create it. All the artists and crafters can take advantage of the advanced features of the 3D printers and UV curing machines to take their crafting ability to the next level.

Well, filaments are suitable to make crafts, but when it comes to fine detailed crafts and objects, you should go for a resin 3D printer, like an LCD  3D printer. Objects made of an LCD 3D printer require post-processing, and this is where you can use a 3d printing UV curing box to give your crafts a stunning look and to make their surface smooth. These technologies are now replacing the traditional craft-making process. How? Let’s discuss about this.

3D model design

After getting an idea of what you want to make, you can create a 3D model of your pictures using different 3D modeling software. Earlier, artists or crafters used to make the design on paper. Now, you can instantly create digital design files or CAD files and slice the design using a slicer so that a 3D printer can print it. What’s more? You can also make a perfect replica of any object by scanning the object using a 3D scanner.

Printing the model

In the 3D printing process, the only time taking a step is creating or designing the model. The rest of the processes are quite straightforward. After creating the design, all you need to do is to transfer the digital design file to the 3D printer, and the printer will carry out the printing process. You can use both the LCD 3D printers or FDM 3D printers. For the best result, we will suggest you go for an LCD 3D printer. Here the liquid resins are cured with the help of UV rays. The entire printing process, based on the complexity of the object, can take a few minutes to a few hours.

UV curing

Once done, the objects are post-processed. This is where you will need a UV resin curing chamber. This is generally carried out to give the object a solid and smooth surface. The resin used in the objects reacts when it comes into contact with UV rays, and the process hardens the object. It will only take a few seconds. This process will significantly improve the properties of the objects by making them chemical and scratch-resistant. Besides, bond strength also increases.

Some benefits to understand

These machines have enabled the users to create a perfect and accurate prototype or crafts within a few hours. These machines are for all, from hobbyists to professional product manufacturers. Both the LED UV curing machine and the 3D printer offer the following impressive possibilities:
