Jigs & Fixtures
Jigs and fixtures designed around the operator's real task
A production aid should locate parts repeatedly, prevent confusion, and survive its expected cycles. Material selection starts with loads, contact points, and environment—not infill alone.
Repeatable location
Hold, place, or align workpieces consistently.
Clear operator steps
Make loading, checking, and removal easier to understand.
Revision-based repeats
Lock the validated file and profile for repeat orders.
Capture the real process
Geometry alone cannot show whether a fixture will survive or be easy to use.
- Push, pull, and twist direction
- Daily cycles and wear points
- Heat, oil, water, and cleaners
Design for the operator
A strong tool still fails if it slows work or allows reversed loading.
- Use keys or asymmetric features
- Provide clear handles and removal points
- Avoid sharp edges and pinch points
Trial and lock
Validate one station or one part before scaling.
- Test with the real workpiece
- Record wear and operator feedback
- Set revision and spare quantity
Decision guide
Inputs that change the design
| Factor | What to capture | Design impact |
|---|---|---|
| Load | Direction and approximate magnitude | Orientation, walls, geometry |
| Heat | Temperature and duration | Material choice |
| Wear | Contact point and cycles | Insert, surface, replaceable feature |
| Operator | Load/unload steps | Ergonomics and mistake-proofing |
Limitations to understand
- —Must be validated with the real part and process
- —Food contact and specific chemicals require separate review
- —High-load work may be better suited to machining or another material
FAQ
Questions before submitting
Should I use PETG or ASA?
PETG suits many general tasks; ASA is more relevant to sunlight and outdoor exposure. Heat and chemicals also matter.
Is 100% infill always best?
No. Walls, orientation, and geometry can matter more while using less material.
Can I order spares?
Yes after validating a test part and locking the revision to avoid mixed versions.
