Description
This contact printer is designed to make 16mm prints using affordable electronics and 3D printing. It is not intended as a replacement for professional printers like the Bell & Howell Model C. This project is for DIY filmmakers, independent artists and small film labs to have a machine that can produce reasonable-quality work prints with a small footprint on short lengths of film easily.
Examples
Contact the first print made on the prototype during a residency at Filmwerkplaats. Soundtrack applied by the opt_snd soundtrack recorder system by Hrvoje Spudić.
