What do I need to consider, when printing VXL support material to make parts, e.g. for lost molds?
You need to consider the same as for model materials with different temperature settings. Printing VXL 111 in an open printer will lead to the same difficulties as printing real ABS in an open printer. Due to the high glass transition temperature, the model will build up residual stresses which might lead to warping or delamination. You should use VXL 70 or VXL 90 in an open printer instead.
