A DLP 3D printer works by shining light into a vat of photosensitive polymer using a Digital Light Processing projector, curing a thin layer of the goo until a solid part has been built up.

There are three main methods of 3D printing within the ... on their usable materials, meaning that most of these are ‘closed’ ...
