Design and Modelling
I designed all the parts in SolidWorks. I downloaded models of off-the-shelf parts, such as motors, on GrabCAD.
I designed the parts to be 3D printed from scratch.

How it works
How it works
The model is a cartesian printer, meaning the hot-end moves in the 3 cartesian axes.
The hot-end is placed on a carriage. The carriage slides on linear rods, and is driven by a belt, to move along the x-axis.
The whole x-axis assembly is mounted on two lead screws, which are powered by two stepper motors. These lead screws move the x-axis assembly in the z-axis.
The heat bed is also mounted on linear rods using bearings, and slides along the y-axis driven by a belt.
All the stepper motors are controlled by an Arduino and a RAMPS 1.4 board. This board receives g-code from the computer, and controls the stepper motors, extruder, and heat bed temperature. The Arduino is configured using the Marlin firmware, which is open-source.

Manufacturing
Manufacturing
The printer was built by assembling all the 3d printed parts and off-the-shelf parts.
3d printed parts include:
Braces for the frame
Supports for the y-axis
Supports for the motors
The carriage
Container for the circuit board
Tensioners
And many more
