When you think about 3D printing, especially with respect to the consumer segment, the first technology to cross your mind is fused deposition modeling. That is not surprising as FDM printers are arguably the most affordable and easy-to-use devices in today’s additive manufacturing market. However, the oldest 3D printing technology is not FDM but stereolithography, or SLA, which remained the privilege of professionals for quite a long time but in the last decade has finally become accessible to consumers as well. Vat photopolymerization, more commonly known as resin 3D printing, is the general term that can be applied to three related technologies, namely SLA, DLP, and LCD, that use liquid photosensitive polymers (or resins) cured by a light source to build a solid object. If you want to learn more about resin 3D printing, read our guide on stereolithography.

This is Top 3D Shop, and in this article, we will tell you about the best machines based on the oldest 3D printing technology. Read on and you will learn how to choose the right resin 3D printer for your particular needs and what tips and tricks you can use to make the best out of its capabilities for amazing flawless prints.

 

How does a resin 3D printer work?

The three above-mentioned resin 3D printing technologies (SLA, DLP, and LCD) are based on vat photopolymerization process. The printing workflow looks as follows:

1. The resin tank, or vat, is filled with liquid photosensitive polymer (resin).

2. The build platform goes down into the vat until a thin layer of resin is left between the bottom of the vat and the print bed. (It is true for most consumer models employing the so-called bottom-up construction where the build platform gradually goes up during printing, and the model is built upside-down. In industrial top-down machines, the build platform stops at a single layer height under the resin surface to build the first layer, and then descends while the part is being built.)

3. The light source cures the resin to build the first solid layer of the future part. And here we come to the difference between SLA, DLP, and LCD machines. SLA 3D printers use a laser beam to selectively cure a layer in a point-to-point manner. Such a method allows for incredible part quality but at the cost of print speed, compared to the other two. In DLP devices the whole layer is exposed to light all at once with a digital light projector used as a light source. LCD 3D printers are equipped with an LCD screen that serves as a mask for the light from an array of LEDs, transmitting the light only in required areas, curing the entire layer at a time.

4. Once the first layer is ready, the build platform goes up (or down) for a single layer height, and the second layer is being built.

5. The process continues until all the layers are built. The part now can be detached from the build platform and post-processed.

A resin 3D printer is a good choice if you are looking for uncompromised part quality, want to create isotropic watertight models with perfectly smooth surface finish, and are ready to spend a bit more money than on an FDM device. As long as resin printers are becoming relatively affordable, their popularity among hobbyists is constantly growing. In the consumer market, the most common type is LCD-based machines as they are the least expensive of the three. Still, even consumer LCD 3D printers can differ significantly in what they can offer to the user and, consequently, in price. To choose the right device that perfectly fits the bill and not to pay extra, it makes sense to define your printing goals and expectations beforehand. Below are some issues worth considering while making a decision.

 

Buyer’s guide: what to consider when buying a resin 3D printer

RGB vs. mono LCD screens

An LCD screen is used as a mask for the light coming from an array of LEDs. Most LCD 3D printers are equipped with monochrome screens but some make use of RGB displays. The latter are cheaper but the downside is shorter lifespan and longer exposure time per layer, because the color pixels have lower light transmittance than those of mono LCDs. We recommend choosing a 3D printer featuring a monochrome LCD panel.

2K, 4K, 6K, 8K LCD screen resolution — what quality do you need?

The print resolution shows how fine a detail your printer is able to produce. However, this parameter is determined not only by the LCD resolution but also by its physical size. If your device is equipped with a relatively small 2K LCD panel, it is perfectly capable of making highly detailed models compared to those built using a 4K or 6K printer with a larger size LCD. On the whole, all modern LCD printers from reliable manufacturers are able to produce parts of high quality that is fairly enough for most consumer projects. So, it is up to you whether you need a higher resolution LCD screen at a higher price.

Build volume

Most consumer resin printers are equipped with rather compact build volumes, yet enough for most home-use needs. If your project implies building immense parts, you can consider buying a large-format resin 3D printer. Besides, you always have the option of printing separate parts of your model and joining them afterwards.

Post-processing equipment

Resin 3D printing always requires a post-processing stage including a minimum of washing the part in isopropyl alcohol to remove the wet resin from its surface, and post-curing under UV light for complete polymerization. This can be done manually but some manufacturers offer full-cycle solutions including wash and curing stations for fast and convenient automated post-processing.

Resin 3D printing tips for beginners

If you are new to resin 3D printing, our “tips and tricks” section will help you avoid print failures right from the start.

How to 3D print with resin

Credit: @unclejessy4real / Instagram

There are a wide variety of 3D printing resins of different colors and properties, like engineering-grade tough, rigid, flexible, or chemical and heat-resistant resins. There are also casting resins used to make mold patterns for creating molds in lost-wax casting, as well as medical or dental biocompatible resins for medical use. For consumer needs, regular, or basic resins are used most often unless your project has any special requirements.

There is one thing you should always remember when dealing with printing resins. While absolutely safe in its cured solid state, the liquid polymers and their fumes are hazardous when contacted with your skin or inhaled. So, it is absolutely necessary to wear protective gloves and use the printer in a well-ventilated room. Wearing a protective mask is not a bad idea either.

The printing process itself is pretty simple. You need a digital 3D model which you prepare using a slicer suitable for resin printing, like ChiTuBox or the program recommended by your printer’s manufacturer. If your printer does not come pre-calibrated, it is important to level the print bed thoroughly to ensure the proper first layer adhesion. Shake the bottle with selected resin material and pour the resin into the vat. Be careful not to overfill it, there is often a fill mark inside the vat. Now you send the print task to the printer, and it does the rest of the job.

When the part is ready, leave it in the printer for some time to drain the excessive resin. After that you can carefully remove the build platform from the printer and gently detach the model using the spatula which usually comes in the box. Now your part is ready for post-processing.

Is resin printing messy?

The short answer is yes. Resin printing can be fairly messy compared to the FDM process. Considering the fact that resins and solvents used for post-processing are toxic materials, you need to dispose of them with all necessary precautions after each printing job. Cleaning the resin vat is also necessary but not the easiest and most pleasant task to do.

Do you need to wash and cure resin prints?

All resin 3D printed parts need to be washed to clear off the uncured resin. To wash the part you need to submerge it into a container with a solvent (isopropyl alcohol is the most common choice) and scrub it with a toothbrush, for example, to remove all the remaining resin.

When the model is clean, you need to carefully remove support structures and cure the part under UV light, so that it could obtain the required mechanical properties. Leaving the part in direct sunlight also works, though the process will take a bit longer. The average curing time is 6–8 minutes, but it may vary depending on the type of the resin used, the power of the light source, and the part size.

To make post-processing easier and faster you can use one of the cleaning and curing stations mentioned before. They are usually two-in-one solutions and can wash and cure any resin parts of suitable size despite your printer brand.

How to paint resin 3D prints

Credit: @hobbydad90 / Instagram

Before applying paint to your resin model, it is a good idea to use a primer to smooth and even the surface. There are special model-making paints, but acrylic and water-based paints can work too, although they may require two or more layers.

Can you make resin molds with a 3D printer?

There is a special-purpose type of casting resins designed specifically for investment casting. These wax-like materials are used to build negative mold patterns which are used to create molds for wax-lost casting. Casting resins are widely used in jewelry manufacturing and in the dental industry. The 3D printed resin mold patterns burn completely leaving almost no ash or residue. Besides, the use of 3D printing allows for unlimited customization opportunities hardly possible with traditional manufacturing.

Can you mix resins for 3D printing?

You can definitely mix resins of the same type using different colors and even brands. As for different resin types, it can be a good idea to mix, for example, basic and flexible resins to add elasticity to your model. But such mixtures require certain printing experience as you have to adjust print settings, such as exposure time, that can vary for different resin types. Anyway, you are free to experiment, and eventually you will realize what works best.

Can you reuse 3D printer resin?

Uncured resin left in the vat can be reused for future prints unless it contains inclusions of even slightly cured material. The uncured resin should be collected and filtered after printing and kept in a UV-protected container.

Polymerized parts can not be melted and reused, as heated resin burns rather than melts and does not restore its initial properties.

Credit: @glimmsaum / Instagram

How long can you leave resin in a 3D printer?

You can leave resin in the vat for several months if you are absolutely sure it is not exposed to any UV light. Cover the vat, or better the printer, with a UV-resistant cover. Yet, if you are not planning on using the resin in the nearest future, it is safer to filter it and put it into a UV-protected bottle for storage.

Credit: reddit.com

Does 3D printer resin expire?

Stored properly, resin can keep its properties for a year or even longer, however, you may notice some quality degradation if you try using it after the expiration date. To prolong the lifespan of the resin, keep it in its original package in a cool dark place and never expose the bottles to direct sunlight.

How to dispose of 3D printer resin?

As mentioned, liquid resin is not environmentally friendly and should be disposed of with special care. Never pour liquid resin or solvents into drains. To dispose of the liquid resin that can not be filtered and reused, you need to completely cure it to a solid state, either leaving it in direct sunlight for several days, or using UV light source. All objects that have been in contact with liquid resin, like gloves or paper towels, should be also exposed to UV light to make sure they do not have any residues of liquid resin. After that you may dispose of the cured resin as household waste.

Solvents used for washing resin parts should be poured into a container and disposed of as chemical waste according to your local regulations.

Why do my 3D resin prints keep failing?

There can be a lot of reasons for resin 3D print failures, and here we will name the most common ways to fix the problem and improve the print quality.

Credit: imgur.com

  • Calibrate the print bed. If the print bed is not leveled properly, it may lead to poor adhesion to the build plate and improper curing of some parts of your model.
  • Check the FEP film. If the FEP film covering the bottom of the vat has a hole in it, the resin can be cured on the surface of the LCD screen. This will not allow for the light to pass through the screen in the dirty area, which will lead to partially unsolidified models. So replace the FEP film in case it has any holes or scratches.
  • Warm the resin if necessary. The resin prints better in warm conditions, so be sure the temperature in the room is not below 20 °C.
  • Adjust the exposure time. Underexposed layers lead to incomplete resin polymerization and, consequently, to print failures.
  • Use proper part orientation. For better adhesion try to avoid large flat layers. The general rule for resin 3D printing is to place the model at the 45° angle to the build plate.
  • Use enough support structures. It is absolutely necessary to use supports to avoid model deformation and curling. Most slicer software generates supports automatically but you may want to edit them for better results, especially if you are printing a complex part with a lot of overhanging elements and holes.
