This document summarizes and compares three types of 3D printers: Polar, Delta, and Cartesian. It describes the basic design and components of each, including the number and type of motors, movement mechanisms, bed shape, and positioning systems. Experimental prints were completed with each printer to compare printing time and accuracy. The Polar printer was fastest, while the Cartesian was slowest but most accurate. Printing speed was also varied between 40-100mm/s, showing faster speeds increased error but decreased time for the Delta and Cartesian printers, while the Polar printer was less affected by speed.

Polar, Delta and Cartesian 3D Printer
Construction of Polar, Delta and Cartesian 3D Printer Polar 3D Printer • Structural frame of Cantilever Type. • Home position orientation is at Center of the bed (0,0,0). • Number of stepper Motors used is 4. • Works on the Polar Coordinate System. • Extruding mechanism consist of GT2 Pulley. • Consisting of a Circular Bed type. • Number of EndStops used 2. • Polar use Smooth rod as a Guiding Mechanism. • Z-axis Movement use Lead Screw . • Y-axis Movement use Gear Train . Delta 3D Printer • Structural frame of Hanging Type. • Home position orientation is at Center of the bed (0,0,0). • Number of stepper Motors used is 4. • Works on the Cartesian Coordinate System. • Extruding mechanism consist of Spring Mechanism. • Consisting of a Circular Bed type. • Number of EndStops used 4. • Delta use Guiding Rails as a Guiding Mechanism. • Z-axis Movement use Belt drive. • Y-axis Movement use Belt drive. Cartesian 3D Printer • Structural frame of Beam Type. • Home position orientation is at Vertices of the bed (0,0,0). • Number of stepper Motors used is 5. • Works on the Cartesian Coordinate System. • Extruding mechanism consist of GT2 Pulley. • Consisting of a Rectangular Bed type. • Number of EndStops used 2+ Pinda Probe. • Cartesian use Smooth rod as a Guiding Mechanism. • Z-axis Movement use Lead Screw. • Y-axis Movement use Belt drive.
