Strengths
& uses
For nested geometry and support-free surfaces FDM cannot match — and when a well-oriented FDM print does the job for less, we will say so.
Strengths
- USP Class I–VI and FDA Intact Skin rated — the skin-contact pick of the lineup
- No tooling — scales to volume
- Dyeable to a deep, even black
- No support marks — any geometry
Common applications
- Production end-use parts
- Functional housings and enclosures
- Living hinges
- Snap-fit assemblies
