Technology & Products
Key Products
FDM (Stratasys Fortus, incl. AICS aerospace interiors); Multi Jet Fusion / HP MJF (incl. PA12, TPU; multiple 5620 systems); SLS (EOS P396, glass/carbon-filled and aeronautical materials); CFIP continuous fiber injection (Reinforce3D Delta); PolyJet (J750); SLA; DMLS metal AM; CNC machining; silicone tooling / vacuum casting pre-series; carbon-fiber process tooling (soluble mandrels, lamination molds); engineering CAD/CAM (Siemens NX); reverse engineering & laser-scan QC; surface finishes (incl. vapor smoothing)
Technological Advantage
VERIFIED: Build capacity for monolithic parts up to 1m² enables single-piece production impossible with competitors; dual-platform approach (FDM + MJF) provides material flexibility; aerospace certification (AS 9100) and membership in Venetian Aerospace Innovation cluster (AIR) locks in defense/aero customers; Reinforce 3D partnership positions Spring as early adopter of fiber-reinforced polymer AM (CFIP), differentiating from traditional service bureaus
Differentiation
Value Proposition
Reduce product development cycle from weeks to days using advanced FDM/MJF technology; produce functional test parts and low-volume production components at 70% of output with aerospace-certified quality (AS 9100); eliminate subcontracting delays through in-house engineering, CAD/CAM design, and laser-scanned QC
How They Differentiate
VERIFIED: Spring differentiates via (1) large monolithic build capacity (up to 1m²) vs. standard ~600x600x600mm for many competitors, enabling single-part production; (2) aerospace pedigree with AS 9100 certification and 20+ years experience vs. generalist bureaus; (3) Reinforce 3D exclusive alliance for CFIP composite AM — early-stage differentiator not available from larger competitors; (4) engineering services depth (CAD/CAM expertise, laser QC, reverse-engineering) beyond print-only competitors
