Technology & Products
Key Products
LINK SL-600 and LINK-SL1600 large-format vat photopolymerization (SLA) printers with domestic-first dual-laser technology; LINK SL-1500 dual-laser industrial SLA printer supplied to Hyundai Motor; LINK EP-500 high-heat-resistance material-extrusion printer; BLT-S450 metal powder-bed-fusion printer; 3D scanners; contract 3D printing/foundry production services; DfAM, reverse engineering and structural analysis design services.
Technological Advantage
Domestic-first dual-laser large-format SLA printer technology; in-house metal PBF equipment; AS9100/KS Q9100 aerospace quality certification; planned autonomous 'dark factory' system linking printers, process data, automation, logistics and post-processing into continuous production at the new Daejeon-area foundry.
Differentiation
Value Proposition
Combines proprietary industrial 3D printer manufacturing (large-format dual-laser SLA and metal powder-bed fusion) with an in-house, AS9100-certified contract production foundry, helping customers move from prototype validation to qualified mass production.
How They Differentiate
Unlike pure equipment vendors or pure print-service bureaus, LinkSolution designs and manufactures its own large-format SLA and metal PBF printers and runs them itself inside an AS9100-certified foundry, targeting the transition from one-off prototypes to qualified production volume.
Market & Competition
Target Customers
Aerospace/defense primes and suppliers, automotive OEMs (Hyundai, Kia), robotics companies, semiconductor/electronics firms, and industrial manufacturers needing large-format, high-precision 3D-printed components.
