Some objects, e.g. with an uneven bottom or overhanging structures, require the use of PVA as supporting material. It can be solved in water what usually is working.
But I now have some objects (printing material PLA) that have very small canals / tubes inside. It is a pity but the Cura slicing software will also fill these canals with PVA. After having printed the object it is now impossible to remove the PVA from within the small tubes (diameter 2mm).
1.) Is there any way of how to enhance the solubility coefficient of the PVA?
2.) Is there any way of how to tell the Cura slicinig software not to uses PVA INSIDE an object but only OUTSIDE (e.g. for an uneven bottom)?
Thanks a lot in advance for answering my questions
