Defaults: Ti-6Al-4V on EOS M290. Adjust any value live. Open the full calculator for SI/imperial toggle, save & export.
From description to cost estimate — no CAD file needed.
Type what your part looks like. Part Sketch generates a 3D model using AI, extracts the bounding box and estimated mass, then pre-fills the Cost-Per-Part and Build Time calculators automatically.

Carbon footprint of additive manufacturing: why every database disagrees
ecoinvent, IDEMAT, ICE (Bath), and GREET give different emission factors for the same metal powder. Here's why, which one to cite, and what it means for your LCA.
