Double Exposure method


#1

I have created a test print that checks for adhesion based on exposure time AND layer thickness. In order to get true multiple layer thicknesses within the image slices (not stacked on top of each other), I had to double, triple, and quad expose layers within the image stack.

Example:
layer 1 = 10um
layer 2 = 10um AND 20um
layer 3 = 10um

layer 5 = 10um AND 50um

layer 10 10um AND 100um
…etc…

This required that for the multiple exposure layers, I had to stop the tray rotation AND prevent the build head from lifting up. I then changed the exposure time for thicker “layers”.

interesting topic. i am working on similar concept.
