Propylene Carbonate is superior to TPM. It cuts through the resin 4-5 times
faster, water soluble, cheap and non-hazardous (its used in perfume and some
food products).

Subject: alternative solvent for sla parts?
Has anyone tried a different solvent, besides TPM, to clean the sla parts?
Southern California AQMD is a little more strict about the environment.
The internal Environmental office does not feel that TPM meets AQMD rule
1122 section c and d. Thus there is a need to find an alternative way to
clean sla parts. Rule 1122 says that a cleaning material shall have less
than 50 g/l of VOC as used. Or be used in an airtight or airless cleaning
system.
If I want to keep using my RAMCO wash station I need to use something else
besides TPM. (less than 50 g/l of VOC)
If I want to keep using TPM I need to buy another cleaning system, maybe an
ultrasonic cleaning system.
