can be constructed for <$600, have made the cost of rapid pro-
ating nature (approximately 50% of its own parts can be self-printed) makes it an extremely
useful platform for open-source fabrication and maintenance of laboratory equipment. The
printing process for the additive layer manufacture of scientific experimental components dis-
cussed in this chapter is a sequential layer deposition. The RepRap extruder intakes a ilament
of the working material, then the Z (vertical) axis will raise, and the extruder will deposit an-
other layer on top of the first. In this way, it can build three-dimensional models from a series
of two-dimensional layers [
