VPP (Metall-indirekt)
Vat Photopolymerization (SLA/DLP for investment casting / slurry)
ISO/ASTM Vat Photopolymerization family. Liquid resin is cured by UV light. For industrial metal AM, VPP is primarily an indirect process (producing patterns for investment casting).
Operating Principle & Process Flow
Operating Principle: In hochspezialisierten Anwendungen (Lithography-based Metal Manufacturing) werden Metallpulver in Photopolymerharze (Slurries) gemischt, gehärtet, entbindert und gesintert.
Process Flow: Druck des Slurries (Harz+Metallpulver) → Reinigen → Thermisches Entbindern → Sintern.
