KS168C - Investment Casting

Material Overview

KS168C is a new generation of stereolithography resin specially developed for the production of investment casting patterns after long-term innovation by Kings R&D team. This transparent resin was created to improve the repeatability and quality of 3D-printed casting patterns. Patterns created with this SL material have higher precision and toughness, and have good dimensional stability, In addition, it has excellent processability, making it an ideal material for investment casting.

Ideal Applications

Patterns for investment casting

Transparent display models

Conceptual prototypes

Tough functional prototypes


Fast to build and easy to finish

Excellent humidity and moisture resistance

Excellent processability

High precision and toughness

Good dimensional stability
