Hello everybody!
I am trying to print a prototype of face masks for non-invasive ventilation (NIV) (see figures below and figures 2-3-4 on this paper to get an idea of the model Development of a 3D Individualized Mask for Neonatal Non-Invasive Ventilation - PMC )
I have designed a prototype but I am finding it very hard to print with my Form 3B, using both the Flex80A (transparent) and BiomedBlack. The problem is that the inside concave part (i.e., the part in contact with the face) and the flow pathway come out filled (see pics below).
Do you have any suggestions/explanations on why this is happening and how to solve this problem?
Thanks in advance
