What is 3d printing with resin

3D printing with resin is a process of creating three-dimensional objects from a digital file. The printer uses a light source to cure layers of liquid resin, one layer at a time. This technology has been around for decades, but it has only recently become widely available to consumers. 3D printing with resin has a number of advantages over other 3D printing technologies. It is capable of producing very precise and detailed objects, and the material properties of the finished product can be controlled more precisely than with other methods. In this blog post, we will explore the basics of 3d printing with resin, including how it works and what its advantages are.

What is 3D Printing?

3D printing is a process of making three-dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes, whereby successive layers of material are laid down in different shapes. 3D printing is the opposite of subtractive manufacturing which involves taking away layers from a piece of material to create an object.

3D printing enables you to produce complex (and often impossible) shapes using less material and less energy than traditional manufacturing methods. It also offers greater design freedom, as you’re not limited by the properties of the materials you’re using or the capabilities of the machines you’re working with.

The most common 3D printing process is fused deposition modeling (FDM), which melts and extrudes filaments of thermoplastic material layer by layer to build up an object. However, there are many other 3D printing technologies available, each with its own advantages and disadvantages.

What is Resin 3D Printing?

Resin 3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects by successively adding material until the desired shape is achieved. Unlike other forms of 3D printing, which use depositing or melting processes, resin 3D printing involves curing photopolymer resin with light. This makes it possible to create highly detailed and precise objects with smooth surfaces.

The most common type of resin 3D printer uses an ultraviolet (UV) laser to cure the photopolymer resin. The UV light causes a chemical reaction in the resin that hardens it. The object is then built up layer by layer from the bottom up. Each layer is cured before the next one is added on top.

Resin 3D printing offers many benefits over other types of 3D printing. It can produce very detailed and accurate parts with smooth surfaces. Resin printers are also generally less expensive than other types of 3D printers.

The Pros and Cons of Resin 3D Printing

Resin 3D printing, also known as stereolithography (SLA), is a popular type of additive manufacturing. Resin 3D printers use an ultraviolet (UV) laser to cure liquid resin into solid layers. The technology is well suited for creating highly detailed models and prototypes with smooth surfaces.

The main advantage of resin 3D printing is its ability to produce parts with very fine features and intricate details. Additionally, SLA parts tend to be stronger and more dimensionally accurate than those produced with other 3D printing technologies.

There are a few disadvantages to consider when choosing SLA for your next project. First, the equipment can be expensive, and the materials can be costly as well. Second, the build times can be long, depending on the complexity of the part being printed. Finally, like all 3D printing technologies, there is a learning curve associated with using SLA printers effectively.

How to Get Started with Resin 3D Printing

If you’re new to the world of 3D printing, resin printing may seem like a daunting task. But fear not! Getting started with resin 3D printing is actually quite simple, and we’re here to walk you through the basics.

First things first: you’ll need a few supplies before you can get started. In addition to a 3D printer that is compatible with resin, you’ll also need a vat of UV-curable resin, a build platform, and some sort of curing device (like a UV lamp or LED array).

Once you have your supplies gathered, it’s time to start printing! The process for printing with resin is similar to other types of 3D printing: first, you’ll create or download a 3D model file, then slice it into individual layers using slicing software. Once your model is sliced, you’ll send the file to your printer and begin the print job.

The key difference with resin printing is that each layer is cured by exposure to UV light before the next layer is printed on top. This curing process helps to ensure that your prints are strong and durable.

Once your print job is complete, all that’s left to do is cure your final piece(s) in a UV oven or chamber for maximum durability. And that’s it! You’re now ready to start creating beautiful prints with resin.

Tips for Successful Resin 3D Printing

Resin 3D printing can be a great way to quickly create high-quality prototypes and models. However, there are a few things you need to keep in mind to ensure success. Here are some tips for successful resin 3D printing:

1. Choose the right resin. There are many different types of resins available, so it’s important to choose one that is suited for your specific application. If you’re unsure which resin to use, consult with a 3D printing specialist or service provider.

2. Prepare your model properly. Resin 3D printing requires very precise models, so it’s important to take the time to prepare your file correctly. Make sure all surfaces are smooth and free of defects, and that your model is correctly oriented for printing.

3. Use the proper settings. Resin 3D printers typically have very specific settings that need to be followed in order to produce the best results. Be sure to consult your printer’s documentation or support team for guidance on what settings to use.

4. Clean your equipment regularly. It’s important to keep your 3D printer and work area clean when working with resin, as even small amounts of dirt or debris can cause defects in your prints. Be sure to clean your equipment after each use, and consider using gloves and other protective gear when handling resin materials.


3D printing with resin is becoming increasingly popular as a way to create high-quality 3D prints. Unlike traditional 3D printing methods, which use filaments that are melted and extruded onto a build platform, 3D printers that use resin cure ultraviolet light-sensitive liquid resins layer by layer to create solid objects. This process results in smoother, more detailed prints with less post-processing required.
