N3D-CAST363
Delivering ultra-low viscosity, minimal ash content, and excellent green strength for investment casting patterns and large, lightweight models.
Low-viscosity casting resin for 335nm large-format SLA systems, designed for clean burnout and reliable green strength.

Overview
Manufactured by Arkema Sartomer
N3D-CAST363 is finely tuned to unlock the full potential of open 335nm large-format SLA printers for investment casting patterns.
With ultra-low viscosity for fast re-coating, minimal ash content for cleaner burnout, and excellent green strength for handling and finishing, this resin is designed to support larger builds and lightweight geometries. It contains no Antimony and no Phosphorous.
