Process: Direct Metal Laser Melting (DMLM) or Sintering (DMLS).
Resolution: 20-30 micron layers.
Finish Process: Bead-blasting or comparable process to remove burrs and reduce surface roughness (before finish machining). Polishing not required.
Heat Treatment: Basic stress relief, single cycle.
Material Certification: Basic material certificate of compliance.
Finish Machining: Per the included prints, “Centerbody Shell and Baffle v1-1 – Critical Finish Dimensions.pdf” and “Pintle Injector v1-2 – Critical Finish Dimensions.pdf”.
