Technology & Products
Key Products
LINK-SL1500 (large-format SLA/vat photopolymerization printer), LINK EP-300 and LINK EP-500 (engineering plastics material extrusion printers), BLT-S450 (metal powder bed fusion for mass production, via AM Solutions acquisition), 3D scanners, design/reverse-engineering and DfAM services.
Technological Advantage
Developed a 2.3m-build-volume SLA 3D printer using proprietary domestic technology; building a large-scale autonomous 3D printing manufacturing foundry with IPO proceeds; robot-based metal AM capability added via AM Solutions acquisition.
Differentiation
Value Proposition
End-to-end 3D printing solutions combining in-house printer manufacturing, design/DfAM services, and large-scale industrial output for prototype and mass production across aerospace, automotive, robotics, and medical sectors.
How They Differentiate
Combines in-house manufacturing of multiple AM process types (SLA, MEX, metal PBF) with contract manufacturing services under one roof, unlike competitors focused on a single technology or bioprinting niche (e.g., Rokit Healthcare's bioprinting focus).
Market & Competition
Target Customers
Manufacturers and OEMs in aerospace/defense, automotive, robotics, and medical device industries needing custom prototyping or ODM/OEM 3D-printed part production.
Industry Verticals
Aerospace/Defense, Robotics, Automotive/Transport, Medical, Industrial manufacturing
