What to use instead
- PSU (Polysulfone) when the temperature and chemical requirement is milder.
- PPSU (Polyphenylsulfone) when the part needs impact strength or daily autoclaving. We do not certify parts for this use.
- PEEK when the requirement is genuinely beyond what any sulfone can hold.
The FDM material selector narrows the whole range by operating temperature, load, chemical exposure, and budget.
