I have a question regarding warping/bowing of my prints. I am printing micro lattices, the smallest negative feature is 440 microns, and the smallest positive feature is 300microns. The whole cube is 4mm x 4mm x 4mm and I’m printing in 10 micron layers.
When I print my lattices at 45 degrees, as seen in the photo, everything prints fine, except when I get to the last 1/3 of the structure or so (the top portion of the lattice in the pic below). I get a warping of the struts. I thought it might have to do with the tray rotating and the layers getting misaligned. I tried increasing the wait time before the projector lights up so that the resin can equilibrate and settle but that didn’t do anything.
I am also posting my 5mm and 6mm build. The 5mm came out relatively fine, and the 6mm not so great.
Any ideas what the issue may be?
