Special Consideration when Cleaning Parts
When performing the cleaning procedures provided above, you may
find that it is more difficult to remove the resin from certain parts or
particular areas of a part . The geomety of the part or the orientation of
the part on the platform may result in the following:
•
The part may hold a large amout of liquid resin in a cavity
•
An air bubble may be trapped preventing the isopropyl alcohol
from contacting the part .
In these cases, change the orientation of the parts when cleaning .
Rotate the print platform 90 or 180 degrees to release trapped air
bubbles. This will also expose areas of the part which are saturated
with liquid resin, allowing better exposure to the isopropyl alcohol.
Changing the Isopropyl Alcohol in Containers 1 and 2
The isopropyl alcohol in Container 1 and Container 2 must be replaced after cleaning 12 platforms . The discarded alcohol is
contaminated with uncured resin and is considered hazardous waste . The discarded alcohol must be stored and disposed of in
accordance with all local, state and federal regulations .
Cleaning Parts with 70% Isopropyl Alcohol
You may use 70% (as opposed to 99%) isopropyl alcohol to clean parts. Using 70% IPA requires the following minor modifications to
the cleaning procedures:
•
The cleaning times increase: 2 minutes in Container 1 and 90 seconds in Container 2 .
•
It will take longer to dry the parts with compressed air .
•
The isopropyl alcohol in Container 1 and Container 2 must be replaced after cleaning 6 platforms .
The discarded alcohol is contaminated with uncured resin and is considered hazardous waste . The discarded alcohol must be stored
and disposed of in accordance with all local, state and federal regulations .
