Abstract
Additive manufacturing technology advancements includes the improvement of a threedimensional item by setting down progressive layers of material over one another. It is a
type of Rapid Prototyping, where the three-dimensional model outline is converted into
directions and is sent from a PC to a printer. Blueprints are translated into commands, in
formats such as the G-Code format. The computer sends these G-Codes to the printer
over a serial connection between the computer and the printer. At the other end, the
printer interprets the commands sent by the computer and triggers movement using the
motors accordingly.
3D printers developed for various applications use different materials. One of the most
popular materials used for 3D printers everywhere, is plastic. Further, there are mainly
two types of plastics used. In this application, the material used is taken to be semi-solid
clay. Clay is chosen as the material because of its eco-friendly nature.
Extrusion techniques are the techniques that are used at the extruder block of a 3D
printer. Bowden extrusion is the method in which the filament or material is stored
separately from the printer. Since clay is a relatively heavy material, when compared to
plastics, Bowden extrusion technique is a more practical implementation of a Clay 3D
printer.
