Exceptional Adhesion for Popular 3D Printing Materials

← Back to Which paints can be used to paint resin?

Achieving a smooth, strong, and lasting finish on your 3D printed parts often depends on using a coating that adheres exceptionally well to popular materials like PLA, ABS, and LAYWOOD. Here’s what to consider for best results.

Why Adhesion Matters in 3D Print Finishing

Poor adhesion between coatings and 3D printed plastics can lead to uneven finishes, premature chipping, or surface defects. Ensuring your coating bonds securely is essential for both protective and aesthetic purposes, giving your prints longer-lasting strength and a professional look.

Choosing the Right Epoxy Coating

Specialist coatings such as 3D Finish Fast Coating Epoxy Resin are designed specifically to bond well with popular 3D printing materials. This product delivers a gloss finish, preserves fine details, and eliminates visible layer lines while enhancing mechanical strength. It cures quickly and is suitable for use on PLA, ABS, and LAYWOOD once surfaces are clean and lightly sanded.

Application Tips for Reliable Results

Prepare your print by cleaning and lightly sanding the surface to ensure it’s dry and dust-free.
Mix the epoxy carefully following the recommended ratio (for 3D Finish: 100A:50B by weight or 100A:45B by volume), and stir thoroughly for at least two minutes.
Apply the coating in a stable, temperature-controlled environment, avoiding high humidity or very low temperatures for optimal adhesion and finish.

When This Matters Most

Exceptional adhesion is particularly important for 3D prints intended for display, functional use, or when a flawless, paintable surface is needed. It also supports further customisation, such as sanding or painting after curing.
