Robotics teams need strong, precise, repeatable parts for testing. DFocus supports CNC machined aluminum and plastic parts, 5-axis components, brackets, housings, fixtures, and low-volume production.
Robotics prototype manufacturing should prioritize real material behavior, tolerance stack-up, mounting accuracy, load paths, and fast iteration. CNC machining is usually the main route for functional robotics prototypes.
Functional prototypes need real material behavior
Robotics prototypes often fail when printed parts are used for loads that require machined aluminum or engineering plastics. Choose the process by test requirement.
- ✓CNC aluminum for structural parts.
- ✓POM/nylon for wear and sliding parts.
- ✓SLS for fast lightweight geometry tests.
Tolerance stack-up matters
Robot assemblies depend on mounting accuracy. Critical hole positions, bearing seats, alignment surfaces, and fastener interfaces should be called out in the drawing.
- ✓Define datum references.
- ✓Mark critical dimensions.
- ✓Ask for inspection on alignment features.

FAQ
Is CNC better than 3D printing for robotics parts?
For load-bearing or precision mounting parts, CNC is usually better. 3D printing is useful for fast geometry and fit checks.
Can DFocus support low-volume robotics batches?
Yes. CNC machining can support prototypes, pilot batches, and repeat low-volume parts.
What drawings are needed?
Send CAD plus 2D drawings for critical mounting dimensions, tolerances, materials, and finish requirements.
