3D printing enthusiast Mo used his seriously homemade, top-down SLA 3D printer, which he built for under $30 to experiment with as a bottom-up design also. Mo's motivation in doing so was that he wanted to test out his Acer projector and see if it would work. Experiencing success with his dual design, Mo shared his list of items which after purchasing the Arduino and stepper motor on Ebay and looking around the house and at the dollar store, totaled $10. It's expected that you could do this for under $30, depending on what you have around the house to contribute to the 3D printer.
