#### NOTE: This is a work in progress. Build instructions and whitepaper to follow.
|
|
|
|
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.
|
|
|
|
This is intended to be a modular printer.
|
|
As of now there is only a single lamp design that uses standard white 5mm LEDs.
|
|
|
|
# Examples
|
|
|
|
[Contact](https://vimeo.com/flashfra/contact?share=git) the first print made on the prototype during a residency at [Filmwerkplaats](https://filmwerkplaats.org/).
