Glossary of 3D Printing Terms [1]

Epoxy Resin Epoxy resin is a two-part material often used in 3D printing for post-processing and finishing prints. Composed of a resin and a hardener, it cures to form a durable, glossy surface when mixed and applied to a print. Epoxy resin is particularly popular for SLA (stereolithography) and DLP (digital light processing) prints, where it can fill in small imperfections and provide a smooth, professional finish. It is also used to strengthen prints, improve water resistance, and create a high-quality aesthetic. When working with epoxy resin, safety precautions are essential due to the potential for skin irritation and fumes. Proper ventilation, gloves, and protective eyewear are recommended. Additionally, epoxy resin can be tinted with pigments or dyes, enabling users to achieve custom colors and effects. Its versatility makes it a favorite among makers and professionals looking to elevate the appearance and functionality of their 3D prints.
