During the past few months I’ve been getting a laser up and running. It has an f-theta scanning lens which has a field of view of about 100 mm diameter so I have to manually position things that are bigger. I’ve been designing an X-Y system to allow me to process bigger parts and I’m currently building this out of plywood (using the laser to cut out the pieces). Anyway, I’ve been following the RepRap movement (open source 3D printers) for quite a few months now and I’d love to build one… but I’m short of cash to buy a full kit… so I’m thinking of using the X-Y stages as the basis for a repstrap which I can use to print a prusa mendel ( before moving the stages to their new home under the laser!
