3. 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.

5. Comparative Study and analyses of Polar, Delta
and Cartesian 3D Printer
• The material used Red, Green and White PLA filament of 1.75mm diameter .
•The machines printing prameters:-
# Extruder nozzles size 0.4 mm diameter
# Printing Speed - 60 mm/s
# Layer Thickness - 0.2 mm
# Infill Density- 100%
# Extrusion Temperature- 195°C
# Bed temperature of prusa MK2S is 60°C
# Bed temperature of Micro make D1 and Polar3D was room temperature as
these model not contain heating element.
