For Figure 4 MED-AMB 10 material, it may be necessary to sterilize cured, finished parts to be used in certain medical applications. You can sterilize printed parts by making use of an autoclave or using gamma-ray sterilization. Do not use a dishwasher or thermal disinfector. 3D Systems recommends the following autoclave method as a baseline starting point for sterilization:
- Ensure printed parts are fully cleaned and cured before sterilizing them.
- Place your part in a standard sterilization pouch.
- Apply sterilization by placing the pouch containing the part in an autoclave for 15 minutes at 121°C or 3 minutes at 138°C. Make sure no mechanical forces are applied to the part during sterilization.
- Let the part cool down to room temperature before using it. Make sure no mechanical forces are applied to the part during cool-down.
NOTE: The above protocol is a recommended starting point and may not be appropriate for all cases. Different geometries and use may require adjustment of this protocol to maximize effectiveness.
If using an autoclave for sterilization, you will notice that your part will change color with the sterilization process. This is normal. Please see the before/after images below for reference.

NOTE: Autoclave sterilization may impact the mechanical properties. Small drops in tensile strength, elongation at break, and impact strength may occur. Such changes are typically less than 20%. Use cases that are sensitive to that should be validated.
