Choosing PA 2201
Pigment-free, slightly translucent EOS PA12 for balanced SLS prototypes, hinges and medical-industry models where natural appearance is useful.
- Consider it for
- Surgical cutting-guide and bone-model development · Functional prototypes with hinges or threads · Natural or translucent-looking PA12 parts
- Tradeoffs
- EOS describes medical-industry approval potential, not automatic approval of every finished part. The current sheet reports dry X/Y data and should not be stretched into unsupported Z or conditioned performance.
- Design and validation
- Qualify the exact process, orientation, cleaning and end-use contact. Treat a hinge or thread as a geometry-specific feature that needs representative testing.
- Finishing
- Natural, slightly translucent is the as-printed appearance. Dyeing or coating is a separate step and may remove that visual characteristic; qualify cleaning for any regulated use.
- Before choosing
- Is pigment-free natural appearance needed, or would white PA2200/PA2220 be easier to finish? What finished-part validation is required for the medical use case?

EOS PA 2201 — frequently asked
What is EOS PA 2201 used for?
Pigment-free, slightly translucent EOS PA12 for balanced SLS prototypes, hinges and medical-industry models where natural appearance is useful. Consider it for surgical cutting-guide and bone-model development, functional prototypes with hinges or threads and natural or translucent-looking PA12 parts. EOS describes medical-industry approval potential, not automatic approval of every finished part. The current sheet reports dry X/Y data and should not be stretched into unsupported Z or conditioned performance.
What should I validate before using EOS PA 2201?
Qualify the exact process, orientation, cleaning and end-use contact. Treat a hinge or thread as a geometry-specific feature that needs representative testing. Is pigment-free natural appearance needed, or would white PA2200/PA2220 be easier to finish? What finished-part validation is required for the medical use case?
How can EOS PA 2201 be finished?
Natural, slightly translucent is the as-printed appearance. Dyeing or coating is a separate step and may remove that visual characteristic; qualify cleaning for any regulated use.
