SEGAL FABRICATION  //  SINTER — LASER SINTERING
================================================================

Status:        BETA
Headline:      >99.5% — Achievable metal density

Sinter is Segal's powder-bed fusion platform, spanning SLS for nylon and DMLS for metal. A fibre-laser galvo fuses each layer inside an inert-atmosphere chamber held under tight thermal control, producing dense, isotropic parts. Because the un-fused powder supports the part, SLS geometry needs no support structure at all — nest the build volume full and recover the powder. This is laser *sintering*, not laser cutting: it builds solid parts layer by layer, it does not profile sheet.

PROCESS NOTES
----------------------------------------------------------------
  • Un-fused powder supports the part — SLS geometry needs no support structures.
  • Inert atmosphere (N₂ for polymer, Ar for metal) keeps oxidation out of the melt.
  • In-process pyrometry holds the powder bed within a tight thermal window.
  • DMLS reaches >99.5% density for isotropic, load-bearing metal parts.
