I currently can only print PLA. Will that suffice for this application? Thank you. — You are receiving this because you are subscribed to this thread.

Temperature, humidity, water/air tightness, and sterilisability. It's hard to sterilize PLA with hot steam/gas, if it melts at 100 degrees. ABS or PETG which have much better temperature handling capability might be best. ABS with a acetone vapour bath to smooth the surfaces and make them unable to be used by bacteria as growing surfaces is important for the health/hygiene. — You are receiving this because you commented.

I have personal experience with this - I printed some tool holders for a dentist friend using PETG, and the sterilizer destroyed them.
