The usage of three dimensional printers are gaining ground in both industrial, and home environment nowadays. This technology helps in fast prototyping and manufacturing low quantity polymer parts whose prime cost would be much more expensive using other technologies. This printer will be great help in creating my future projects parts, both in professional and non-professional setting.

This paper covers a full design procedure of a three-dimensional printer, including electronic hardware design, embedded software development and mechanical design.

The main capabilities of the machine which this thesis is based on is similar to the occurrent ones on the market, however I employed some unique solutions which helps to make better output. The work area is 300mm x 300mm x 300mm which is much bigger than the usual consumer printer output sizes. The huge chamber means that bigger objects can be printed, therefore the positioning devices are direct current motors, instead of the stepper motors of the rivals. Foregoing property makes the extruder head movement, and printing much faster. Since the chamber temperature is controlled, hence superior quality is guaranteed even with printing objects of greater height.
