I printed this on the B9Creator, on the 50µm pixel setup and sliced 25,4µm thick. It produces channels ranging from 1,0mm to 0,05mm width and 0,5mm t0 0,07mm deep, To get a slick surface without pixel spikes and nice sharp corners on walls, I want to coat the VAT with PTFE instead of PDMS. It will enable us to print microfluidic chips directly (or better molds).
