Can You Finish 3D Prints with Resin?

Q: How Resin Coatings Improve 3D Prints

Specially formulated epoxy resins, such as 3D Finish , are designed for use on 3D printed materials like PLA, ABS, and LAYWOOD. These resins form a thin, self-levelling layer over the print, eliminating visible layer lines left by FDM machines and creating a smooth, high-gloss surface. Importantly, the resin highlights and protects your model’s fine details without flooding or blurring intricate geometry.

If you’re seeking a smoother, more professional finish on your 3D prints, applying a resin coating is an excellent solution. Epoxy resins provide a glossy surface that enhances both appearance and durability of your printed models.

Guidance for Applying Resin to 3D Prints

To finish your 3D print, start by ensuring the surface is clean and dry. Mix the resin components as per the manufacturer’s instructions. Apply in thin coats—using a brush or pouring method—while maintaining even coverage. Products like 3D Finish cure in about four hours at room temperature and adhere exceptionally well to common print plastics. Once fully set, the resin surface can be polished for extra shine or painted for added detail.

When Is Resin Finishing Most Useful?

Display models and prototypes that require a sleek look
Functional parts needing extra strength and surface sealing
Prints destined for painting or further decoration
