What is the recommended mixing ratio for 3D Finish epoxy resin?

Precise Mixing Ratios: By Volume and By Weight

3D Finish epoxy resin consists of two parts—A (resin) and B (hardener)—and must be blended in the following proportions:

• By volume: Mix 100 parts A to 50 parts B.
• By weight: Mix 100 parts A to 45 parts B.

Using a good quality scale is recommended for accuracy, especially when measuring by weight. If measuring by volume, use graduated mixing cups for the best results.

Blending Technique for Reliable Curing

Once components are combined, blend the mixture thoroughly for at least 2 minutes. Be sure to scrape the sides and bottom of your container as you stir to achieve a fully uniform mix. Incomplete blending can lead to uncured patches or a tacky surface on your finished print.

When Precise Mixing Matters Most

Achieving the correct ratio is vital for a seamless coating, especially when working with intricate models or fine details. Accurate mixing ensures optimal mechanical strength and a smooth, glossy finish—qualities that set apart a professional result from a mediocre one.
