Hi, I’m DWS Systems distributor.
DWS has such material: DS3000. It’s biocomatible (Class 1 certified) and transparent.
It’s main application are surgical guides.
I have no idea how to print it on Formlabs machine, but I suppose it can be done.
You can order it in 2x165g sets, or per kg.
Please contact me if you need any further information.
