// ABOUT_FABRAPID

The jump from working print to working metal should be understandable.

FabRapid is built for hardware teams that already have STEP, STL, or both, and often a validated plastic prototype. We help route that design into CNC machining or metal 3D printing without hiding file and process tradeoffs.

Preserve the best source

STEP is preferred when it exists. STL is accepted, with reconstruction risk made explicit when CNC is selected.

Explain the why

A review should explain why CNC or metal additive fits, what must change, and what still needs confirmation.

Earn trust with specifics

Price, timing, inspection, documentation, and special requirements are confirmed per project rather than claimed universally.

Built for iteration, not procurement theater.

The intended users are robotics developers, independent hardware teams, electronics builders, and research groups who need a small number of functional metal parts and a clear answer about process, file fidelity, and what needs to change.
