Consolidating multi-process prototypes costs more than summing individual part quotes.
Setup costs dominate prototype pricing, but savings plateau much sooner than most engineers expect.
Cold-water erosion avoids heat damage that degrades thick metals and composite edges.
Roll forming handles harder materials and thinner walls where extrusion hits its limits.
Material choice hinges on temperature limits, then chemical exposure, then bonding needs.
SLM wins where CNC geometry fails entirely, but powder escape holes are non-negotiable.
Pick CNC for functional tests on aluminum; SLA fails mechanical and thermal ones.
Sinker EDM handles blind cavities.
