I am using the 3D printed mold as a substrate in order to create a 100 micron PDMS layer. I use a release spray on the surface of the mold before applying the PDMS. However, I am finding difficulties in peeling the layer off. Is it even possible to obtain such a thin PDMS layer from the mold? If so, how is it possible to get the layer to be peeled off smoothly?
What is the photopolymer black resin composed of? details like the functional groups or the chemical constituents would be extremely helpful.
