Getting Started with Resin 3D Printing – A Beginner’s Guide 

Welcome to the exciting world of resin 3D printing! If you’ve been captivated by the stunning precision and intricate designs of 3D-printed objects, resin printing might be just the adventure you’re looking for. In this beginner’s guide, we’ll take you through the fundamentals of resin 3D printing and how to embark on your creative journey. 

Unveiling the World of Resin 3D Printing 

Resin 3D printing, also known as stereolithography (SLA) or digital light processing (DLP) printing, is a remarkable technology that allows you to bring your digital designs to life with astonishing detail and finesse. Unlike traditional filament-based 3D printing methods, where thermoplastic material is melted and deposited layer by layer, resin printing operates by curing liquid resin with a light source, typically a UV laser or LED. This precise layer-by-layer approach results in prints of exceptional accuracy and surface smoothness, making it the preferred choice for those seeking high-quality, finely detailed objects. Let’s delve into the essentials of this fascinating craft.

The Advantages of Resin Printing 

Precision Matters: Resin printers offer unparalleled precision, with layer heights as low as 25 microns (0.025mm), ensuring the finest details in your prints. 

A Smooth Finish: Unlike traditional filament-based 3D printing, resin prints boast a remarkably smooth surface finish, making them ready for post-processing and customization. 

Materials Galore: Resin printing provides a versatile range of materials, including standard, flexible, castable, and engineering resins, catering to a multitude of creative projects. 

Pinpoint Accuracy: It’s renowned for its exceptional accuracy, making it the go-to choice for crafting intricate designs and prototyping. 

Your Journey Begins Here 

1. Choose Your Resin 3D Printer 

Embarking on your resin printing journey starts with selecting the right 3D printer. You’ll find an array of reputable brands like Creality Anycubic, Elegoo, and Phrozen, offering various models to cater to your specific needs. When making your choice, consider factors such as build volume, resolution, and budget. 

2. Set Up Your Workspace 

Before you dive in, prepare a dedicated workspace. Resin printing can get a tad messy, so ensure good ventilation, and have a supply of isopropyl alcohol (IPA) on hand for cleaning. Equip yourself with gloves and protective eyewear for safe handling. 

3. Pick the Perfect Resin

The type of resin you choose depends on your project’s requirements and your printer’s compatibility. Whether it’s standard resin for general use, flexible resin for rubber-like parts, or castable resin for crafting exquisite jewellery, choose wisely. 

4. Prepare Your 3D Models 

To bring your ideas to life, you’ll need 3D models in STL format. You can either create your designs using 3D modelling software like Blender or Tinkercad or explore a treasure trove of pre-made designs on platforms such as Thingiverse or MyMiniFactory. 

5. Slice and Print 

Slicing software (e.g., Lychee, ChiTuBox, PrusaSlicer, or PreForm) comes into play here. It’s the tool that transforms your 3D model into printable layers, generating support structures to ensure a successful print. Follow your printer’s guidelines to load the resin, initiate the print, and witness the magic unfold. 

6. Post-Processing Magic 

After the print is complete, carefully detach your object from the build platform. Submerge it in IPA to remove excess resin, then cure it under UV light for a polished finish. If needed, remove support structures and refine the surface with sanding or polishing. 

7. Prioritize Safety 

Resin printing involves handling chemicals and UV light, so safety should be your top priority. Always don the appropriate protective gear, work in a well-ventilated area, and adhere to the manufacturer’s instructions for responsible resin disposal. 

8. Learn and Experiment 

Just like any craft, mastering resin 3D printing takes practice. Begin with simple projects and gradually work your way up to more intricate creations. Embrace the learning curve and embrace the joy of experimentation. 

Troubleshooting and Beyond 

Expect challenges along the way, such as print failures, layer adhesion issues, or unexpected resin spills. Fear not; solutions are within reach. Online forums, community groups, and manufacturer support can be your guiding lights when troubleshooting. 


Resin 3D printing opens doors to a realm of creative possibilities for beginners and seasoned makers alike. With the right equipment, materials, and safety precautions, you can embark on a rewarding journey of turning digital dreams into physical realities with precision and finesse. Take your time, savour the learning process, and soon enough, your resin prints will captivate all who behold them. Happy printing!
