Liqcreate Bio-Med Clear processing workflow
For reaching the properties as described above and to insure biocompatibility it is
important to follow the validated workflow described below.
Print process
Before printing make sure to shake the bottle for 2 minutes and that the parts are printed
in an environment at 20-25°C. Validated printer settings can be found on our website:
Compatible 3D-printers with Liqcreate resins | Liqcreate.
Wash and cure process
1. Remove the parts from the build platform.
2. Remove the support structures.
3. Wash the parts for 2 minutes in IPA or ethanol in an ultrasonic cleaner.
4. Wash the parts for a second time for 2 minutes in fresh IPA/Ethanol.
5. leave the parts to dry under ambient conditions for a minimum of 60 minutes.
6. Cure the parts for 30 minutes at 60°C in the Wicked Engineering Curebox.
Biocompatibility
Liqcreate Bio-Med Clear has been proven capable of passing the cytotoxicity testing
according to ISO 10993-5:2009, sensitization testing according to ISO 10993-10:2021 and
irritation testing according to ISO 10993-23:2021 within a specific workflow. When using
