Looking to enhance the durability and scratch resistance of your 3D prints? Applying a clear epoxy resin like 3D Finish creates a protective, glossy shell that shields your printed parts and improves their appearance.
Preparing Your 3D Printed Model
To achieve the best results with 3D Finish epoxy resin, start by ensuring your 3D print is clean, dry, and thoroughly sanded. This preparation removes any surface dust or residue, allowing the resin to adhere effectively. Sanding also smooths out the print lines, readying the surface for a uniform coating.
Mixing and Applying the Epoxy Resin
Accurate mixing is essential—measure both resin and hardener by weight according to the ratio specified in the instructions. Stir thoroughly, taking care to scrape the sides and bottom of your container for a fully blended mix. Apply the resin in a dust-free area using a brush or spatula, ensuring even coverage over the entire surface. Avoid humidity and low temperatures for optimal curing.
- Apply a thin, even layer and check for drips or pooling on intricate features.
- Allow to cure for approximately 4 hours at 20°C, or as noted on the product’s label.
Finishing and Additional Protection
Once cured, your 3D print will have a glossy, more scratch-resistant finish. For a truly professional look, the coated surface can be sanded lightly and polished. Using a dedicated product such as Epoxy Polish helps achieve a mirror-like gloss and further minimises visible scratches.
When This Matters Most
Coating 3D prints with epoxy resin is particularly valuable for display models, prototypes, or parts that will be handled or cleaned regularly. It’s well-suited for prints made from PLA, ABS, or LAYWOOD where both durability and appearance are important.
