Polymer Implant Machining
Polymer implants fail when deformation and stress release become uncontrolled. We help teams keep geometry stable across builds.
Why Polymer Implant Components Are Different
Polymer implant manufacturing requires stability-driven thinking. Typical risks include:
Deformation Risk
Deformation in thin walls and long features, compromising the intended design.
Stress Release
Stress release causing rebound or dimensional drift after machining.
Variation Across Batches
Dimensional variation that breaks fit behavior across production batches.
Common Issues vs. Rapidaccu Solutions
Common Polymer Implant Issues
- Thin walls deform and shift
- Stress release changes dimensions after build
- Prototype fits, production drifts
- Fit behavior changes between batches
- Revision notes cause confusion
How We Help Reduce the Risk
- Identify stability-critical features early
- Support stability-driven review and clarify CTQ
- Align dimensional verification with functional fit
- Support batch identification and repeatability
- Apply clear revision tracking and communication
Our Stability Playbook
To improve repeatability, we provide these inputs during drawing review to reduce prototype surprises.
Define CTQ Dimensions
Clearly define critical-to-fit dimensions to focus inspection and control.
Use Stable References
Use stable reference definitions to avoid ambiguity in measurements.
Control Feature Relationships
Control relationships between features that drive the component’s functional fit.
Review Risk Areas
Proactively review thin walls, long slots, and unsupported structures.
Prototype vs Production: Why It Matters
Polymer programs often pass prototypes but struggle in repeat production because stability-critical features weren’t defined clearly, inspection points didn’t match functional fit, and revisions introduced hidden risks. We help align engineering intent with production verification from day one.
Align Your ProductionQuality System & Medical Best Practices
Rapidaccu operates under ISO 9001:2015. For polymer implant programs, we support:
Drawing Review
Stability-driven drawing review and critical feature confirmation.
Revision Tracking
Clear tracking to prevent drift from mixed builds.
Inspection-Ready Outputs
Outputs aligned to your program workflow and requirements.
Batch Identification
Support for batch traceability and repeat orders.
Frequently Asked Questions
Why does a polymer prototype fit well, but later batches drift?
Drift often comes from deformation and stress release combined with unclear CTQ definitions. We focus early on stability-critical features and verification logic to ensure consistency from prototype to production.
What features are most sensitive in polymer implants?
Thin walls, long slots, and unsupported geometries are typically most sensitive. These features require stability-driven planning and careful process control to maintain dimensional accuracy.
Can you support documentation for approvals?
Yes. We can provide comprehensive inspection outputs, material certifications, and batch identification documentation aligned to your specific program and regulatory requirements.
What materials do you work with?
We commonly machine high-performance polymers such as PEEK, as well as other engineering polymers defined by the program’s specific functional and biocompatibility requirements. See our materials page for more.
