Cleaning:
a. Allow the model to clean for 3 minutes in compartment 1 of the MEDIFIVE washer containing ethanol solution (96%). After the process is complete, dry the model with a spray air gun.

b. Allow the model washed and dried in compartment 1 to be cleaned in compartment 2 of the MEDIFIVE washer containing ethanol solution (96%) for 3 minutes. After the process is complete, dry the model with a spray air gun.

Do not exceed the 6-minute total cleaning procedure as this may cause deterioration of printed objects.

Hint: Resin residues can also be removed using a brush moistened with ethanol (96%).

Finishing:

The completely cleaned print objects must be post-cured to attain the required material properties and biocompatibility.

7- Post-Curing

Caution: Post-curing outside of the recommended settings can lead to suboptimal mechanical and biocompatibility properties. Post-cure only in accordance with official recommendations from Power Resins for the best possible results.

Recommended post-curing

2x2000 flash on Otoflash G-171 curing device
