Technology & Products
Key Products
LimitState:GEO (geotechnical ULS analysis via DLO); LimitState:RING (masonry arch bridge analysis); LimitState:SLAB (reinforced concrete slab yield-line analysis); LimitState:FIX (one-click 3D mesh/STL repair via Polygonica); LimitState:FORM/Peregrine (topology/layout optimization for lightweight structures, incl. Synera module).
Technological Advantage
Verified advantage: LimitState:FIX fixes vastly more mesh errors than competitors in tests, using patented Polygonica technology. Defensible via software IP and integration with industry-standard tools like Rhino/Grasshopper.
Differentiation
Value Proposition
Reduces 3D printing preparation time by up to 90% through one-click mesh repair and enables 20-40% weight savings in components via topology optimization, cutting material costs and accelerating design-to-print workflows.
How They Differentiate
One-click mesh repair with Polygonica technology fixes more errors than Materialise Magics (e.g., wall thickness, shell completion) and offers topology optimization via LimitState:FORM for lightweight AM designs, unlike general CAD tools.
