Technology & Products
Key Products
Large-format industrial SLA/DLP systems with open 355nm (laser) / 385–405nm (DLP) resin compatibility: PR800/7 (800×700×200–600 mm), PR700 (700×700×100–500 mm), PR450 (450×450×350 mm), PR400i dual-projector DLP (420×384×50–400 mm, up to ~10× faster than traditional SLA), plus MDK+ material development kit and own resins (e.g. RR355). SmartBuild automation and Materialise Magics/Build Processor included on production platforms.
Technological Advantage
Combines large industrial SLA build envelopes (current production range up to PR800/7 800×700 mm; historical PR2400 2400 mm class) with HD+ accuracy, open 355nm materials, SmartBuild automation, Materialise integration, and defence-oriented credentials (JOSCAR, Cyber Essentials, MOD/BAE programmes).
Differentiation
Value Proposition
Delivers high-reliability, large-scale additive manufacturing with an 'Open Material' philosophy, allowing users to avoid proprietary resin lock-in and optimize costs for 24/7 industrial workflows.
How They Differentiate
Raplas differentiates through an 'Open Material' philosophy, allowing industrial users to use third-party resins and avoid proprietary lock-in. They also offer extreme large-format build volumes (up to 2400mm) and military-grade software security (INTEGRA Plus) for defense applications. Their PR 400i model features dual-projection DLP technology, delivering speeds 10 times faster than traditional SLA systems.
