I already have complete 3D CAD files for a compact device that falls in the 10-30 cm range. I now need a partner who can take those files, CNC-machine the components in stainless steel, apply an anodized finish, assemble the parts to final form, and ship the ready-to-test prototype back to me. Key points of the job • Material: stainless steel only—please confirm your stock grade and certs. • Finish: anodizing is required on all visible surfaces; colour is flexible, but the coating must be even and durable. • Size: overall footprint lands squarely in the medium (10-30 cm) bracket, with several tight-tolerance mating features (±0.02 mm) that must line up perfectly at assembly. I will supply STEP files, drawings with critical dimensions, and a short assembly guide. If you spot DFM issues, I welcome feedback before cutting chips. Deliverables 1. Machined stainless-steel parts that meet the provided tolerances. 2. Anodized finish applied uniformly. 3. Fully assembled prototype, cleaned, packaged, and shipped. 4. Brief dimensional inspection report or photos verifying key features. If you have the in-house capability to machine, anodize, and assemble—or reliable vendors you manage regularly—please let me know your typical turnaround time and any questions you have about the models. I’m ready to start as soon as we’re aligned on the workflow.

Hello there! Your prototype project sounds very interesting, and I appreciate that you're looking for someone who will review the design before machining rather than simply manufacture it. With extensive experience in mechanical design, CAD/CAM, CNC manufacturing workflows, and prototype development, I understand the importance of DFM review, machining strategy, tolerance control, and assembly verification. I'll carefully evaluate your STEP files and identify any features that could affect manufacturability before production begins. **My plan:** 1. Review your STEP files, drawings, and assembly guide for manufacturability. 2. Identify any DFM improvements or tolerance concerns before machining. 3. Coordinate CNC machining using certified stainless-steel stock and verify the required material grade. 4. Manage the finishing process and ensure a consistent, durable surface treatment that meets your specifications. 5. Assemble the prototype, inspect the critical dimensions, and document the results with photos or an inspection report. 6. Package the completed assembly securely and prepare it for shipment. The most critical factors will be maintaining the ±0.02 mm mating tolerances, selecting the appropriate stainless-steel grade, and ensuring the specified finish is compatible with the material.
