What Is Rapid Prototyping?
Rapid prototyping means making a working part fast so you can test it before committing to production tooling. We CNC machine prototypes from solid metal or plastic blocks. Bellevue teams use our rapid prototyping to validate designs, test fits, and prove concepts.

Rapid Prototyping Capabilities for Bellevue Teams
Bellevue is known for Microsoft and T-Mobile headquarters driving demand for precision tech hardware and server components. We handle the precision machining these industries demand.
CNC Milled Prototypes
Flat, prismatic, and sculpted prototype parts from 3-axis to 5-axis. Same machines and tolerances as production runs.
Most popularCNC Turned Prototypes
Round prototype parts -- shafts, bushings, and pins. Live tooling adds flats and cross-holes in one setup.
Round partsMulti-Material Prototypes
Test different materials on the same design. Compare aluminum 6061 vs 7075, or Delrin vs PEEK, before committing.
Material testingFunctional Prototypes
Parts that work under load, pressure, or heat. Real material properties, not 3D printed approximations.
Real materialsFirst Article Runs
Bridge the gap between prototype and production. 5 to 50 pieces with full inspection and documentation.
Pre-productionDesign Iteration Support
Fast turnaround on design changes. Send a revised STEP file and we re-quote within hours.
