2. What is 3D PRINTING ?
 3D printing or additive manufacturing is a process of
making three dimensional solid objects from a digital file.
 The creation of a 3D printed object is achieved using
additive processes. In an additive process an object is
created by laying down successive layers of material until
the object is created. Each of these layers can be seen as
a thinly sliced horizontal cross-section of the eventual
object.

3. Fused Deposition Modeling (FDM)
Fused deposition modeling (FDM) is a additive manufacturing technology commonly
used for modeling, prototyping, and production applications.
The thermoplastics are liquefied and deposited by an extrusion head, which follows a
tool-path defined by the CAD file. The materials are deposited in layers as fine as 0.04
mm (0.0016") thick, and the part is built from the bottom up – one layer at a time. A
plastic filament or metal wire is unwound from a coil and supplies material to an
extrusion nozzle which can turn the flow on and off.

5. COMPONENTS
Software used:
1.Arduino based Marlin firmware.
2.Slicing software to design gcode fies eg Slic3r,cura
Arduino Mega with RAMPS 1.4 Controller
Aluminum Extruder Kit
0.4mm Extrusion Head
Endstops
A4988 Stepper
Motor Driver PLA & ABS
Filaments

6. :Filaments used:
Other Filaments:
PVA: Polyvinyl Alcohol: Because it is soluble, this material is generally used
to manufacture supports, as they can be easily removed from the part after
manufacture
TPU: Polyurethane: Used to create flexible parts

Microcontroller.
.STL files are Sliced into many
2D layers based on different
parameters using Slic3r and
corresponding G-code file is
generated which is platform
independent as java’s
bytecode.
Slic3r
Host Pronterface reads the G-code
commands and send it to Marlin
firmware in arduino board which in
turn commands Stepper motors
to move specific steps.

14. FEATURES of material (PLA) :
• CAS Number :26100-51-6
• Chem Spider: none
• Cost efficient – 11000 INR.
Identifiers
• Density:1.210–1.430 g·cm−3
• Melting point:150 to 160 °C (302 to 320 °F; 423 to
433 K)
• Solubility in water: Insoluble in water
• PLA polymers range from amorphous glassy
polymer to semi-crystalline and highly crystalline
polymer with a glass transition of 60 °C and
melting points of 130-180 °C. PLA has a glass
transition temperature 60–65 °C, a melting
temperature 173–178 °C and a tensile modulus
2.7–16 Gpa.

15. APPLICATIONS AND FUTURE SCOPE :
A Process called bio texture modeling allows us to print
stimulated organs with texture & wetness of real things.
3D Scans of patients can help create custom
built prosthetic and face prosthetics.
Customized bone replacements can be
executed 3D printing.
Orthodontic appliances, temporary teeth,
dental crowns can be 3D printed.
Bio printing is the process of printing out
organic tissue which could facilitate organ
transplants.

16. CONCLUSION
We get high precision regardless of uneven heating or bowed
build plate.
Sensors ensure the print head is always moving parallel to
the build plate.
No wasting time fiddling with the bed and Z height .It’s easy
of for inexperienced machinists to use it .
Use of filament effective reduces the wasting of filaments.
Hence we are intended to produce a low cost 3D printer for all
with an estimated cost of 11000 INR.
