Which Resin is Best for Coating 3D Prints?

Why 3D-Specific Resins Make a Difference

Using a resin designed for 3D prints ensures compatibility with common filaments like PLA, ABS, and LAYWOOD. Resins such as 3D Finish – Fast Coating Epoxy Resin for 3D Prints are formulated for strong adhesion, which is crucial for a seamless, smooth layer over printed parts. The right product preserves model details while eliminating visible layer lines.

Practical Tips for Resin Coating 3D Models

• Mixing with Accuracy: Always follow the recommended ratios—100A:50B by volume or 100A:45B by weight for 3D Finish—to achieve the best results.
• Application: Apply an even layer with a brush or pour and tilt for full coverage. The non-drip formula helps maintain the shape and definition of your print, reducing runs and sags.
• Finishing: Allow to cure at room temperature (around 20°C) for optimal performance. Once cured, the surface is both paintable and polishable, making it ideal for customisation.

When This Matters

Coating is particularly important when you want to strengthen your 3D printed items, improve the tactile and visual quality, or prepare your model for painting. It’s also invaluable for repairing minor surface blemishes.
