We support DXF, STEP, and IGES formats — the most commonly used file types across CAD, CNC machining, and digital manufacturing workflows. Whether you're working on 2D technical drawings or complex 3D models, our platform is built to handle your files with precision and speed. Once your files are uploaded, our expert engineering team carefully analyzes them to ensure design accuracy, structural integrity, and production feasibility. You’ll receive detailed pricing based on material, process, and volume, along with ideal material recommendations tailored to your project's functional and mechanical requirements.
Sheet metal fabrication is the process of cutting, bending, and assembling flat sheets of metal or non-metallic materials to create functional parts and enclosures. At ProtoMandi, we specialize in two key operations:
| Feature | Laser Cutting | CNC Bending |
|---|---|---|
| Purpose | Cut flat profiles from sheets | Bend/curl sheets into 3D forms |
| Tolerance | ±0.1 mm (typical) | ±0.5° (angle), ±0.2 mm (position) |
| Best For | Intricate shapes, holes, contours | U-bends, flanges, and formed geometries |
