Formlabs Castable Wax Resin is a specialized photopolymer resin for the Form 4, formulated with 20% wax content to support high-quality lost-wax casting workflows. It produces burn-out patterns that leave virtually no ash or residue, ensuring clean mold cavities and high-fidelity metal castings with crisp surface detail.

This resin is the preferred choice for jewelry designers and goldsmiths who need the precision of SLA printing combined with traditional casting quality. It is equally well suited for dental casting applications and industrial investment casting of small, intricate parts. The wax content gives the cured pattern a burnout behavior close to traditional wax models, allowing standard casting schedules and investment materials to be used without process changes. The Form 4's MSLA engine ensures fast, reliable pattern production even for high-detail filigree and fine stone settings.
