Smoothing FDM 3D Prints with Resin: A Step-by-Step Guide

In today's blog post, we will explore a unique method of smoothing FDM 3D prints by utilizing resin, the same material used in 3D printing. Unlike traditional methods like wood filler or XTC-3D, resin offers a different approach to achieving a smooth finish on your prints. Let's delve into the process and see how resin can effectively diminish those visible layer lines for a flawless end result.

Unveiling the Resin Smoothing Technique

The Inspiration Behind the Method

The concept of using resin to smooth 3D prints was first introduced by Galactic Armory in one of his videos. This innovative technique involves applying resin from a 3D printer onto FDM prints to achieve a polished, professional finish. The idea is to create a seamless surface while preserving intricate details.

Essential Materials for the Project

To embark on this resin smoothing journey, you will need:

Your 3D printed model
Resin (in this case, Elgoo's water washable ceramic gray and ABS-like resin)
Gloves for safety
Applicator brushes
UV light for curing
Containers for resin mixing
Sandpaper for finishing touches

The Smoothing Process

Preparation: Ensure your print is clean and free of any debris before beginning the process.
Application: Using a brush, apply a thin, even layer of resin onto the desired areas of the print. For detailed sections, opt for a thinner resin consistency.
Curing: Cure the resin using a UV light or direct sunlight, allowing it to harden and create a smooth surface.
Finishing Touches: Lightly sand the cured resin to further refine the smoothness of the print.

Results and Reflection

Front Side Results

After applying and curing the resin, the front side of the print showcased impressive smoothness with minimal effort. The resin effectively masked the layer lines, providing a professional finish that is ready for priming and painting.

Back Side Experiment

While the back side retained most of its intricate details, there was a slight loss of texture, possibly due to excess primer or resin application. Further experimentation is needed to fine-tune the process for intricate prints.

Conclusion and Recommendations

In conclusion, the resin smoothing technique offers a promising alternative to traditional methods of finishing 3D prints. By incorporating resin into your workflow, you can achieve smoother surfaces and enhance the overall quality of your prints. Experiment with different resin types and application methods to find the optimal approach for your projects.
