Need PCBs, CNC machined or 3D printed parts? Check out PCBWay: Today's video is a continuation of my previous one on photolithography. Using a custom-built apparatus that projects a mask onto the photoresist through a lens system, I can achieve structures in titanium on glass with a resolution of 20 micrometers through subsequent sputtering.
