Replacement Parts
Start replacement parts from function and risk—not copied shape
Parts that look alike may perform very differently. Before deciding whether FDM is suitable, capture loads, heat, mating features, original material, and the consequence of failure.
Print-ready file
Upload STL/3MF to check size and enter the quote workflow.
Physical part, no file
Submit photos, dimensions, and function for modeling or reverse-engineering review.
Test first
Validate fit and operation before stocking or continuous use.
Screen the risk
Not every spare part should be made with FDM.
- Do not substitute safety parts without qualified approval
- Review heat, load, and consequence of breakage
- Use OEM or machining when more appropriate
Capture the original
Photos alone are insufficient for mating parts.
- Measure overall size, holes, and center distances
- Photograph multiple views with a scale
- State original material and failure cause
Rights and revisions
The requester must have the right to use the design or reproduce the part.
- Infringing files or products are not accepted
- Name the revision and measurement date
- Keep the validated test part as a repeat reference
Decision guide
Replacement-part paths
| Available input | Path | What to verify |
|---|---|---|
| STL/3MF | Instant quote | Size, mesh, printability |
| STEP/CAD | Custom review | Conversion and tolerance |
| Physical sample | Measure/scan/model | Reference faces and wear |
| Photos only | Initial assessment | Dimensions required before production |
Limitations to understand
- —Not an OEM or safety certification
- —Accuracy depends on source data and measurement
- —A worn or broken sample may not represent original geometry
FAQ
Questions before submitting
Can I send only the physical part?
An assessment can start from the part, its function, dimensions, and environment. The team will identify whether measuring, scanning, or modeling is needed.
Can it be printed in PLA?
That depends on heat, load, and environment. PETG, ASA, or another process may be more suitable for functional replacements.
Is it guaranteed to replace the original?
Not from shape alone. Fit and function must be tested according to the risk of the application.
