Almanac Engineering

Almanac Engineering is a deep-tech hardware startup building lights-out additive manufacturing systems for industrial production. Their flagship product, Prima Materia, is the first selective laser sintering (SLS) 3D printer to autonomously handle the complete workflow — laser sintering, controlled cooldown, depowdering, and post-processing — within a single sealed system, eliminating the need for operators between builds. The system enables continuous 24/7 production with over 80% powder reuse under inert atmosphere, reducing per-part labor costs by up to 95% compared to traditional SLS setups. Starting at $300,000 per unit, Prima Materia targets service bureaus, robotics manufacturers, and defense contractors that need scalable, high-throughput polymer additive manufacturing.
