3D printing has been a great technology in this century of amazing technology. Here is a presentation of a Arduino based 3D Printer which is very cheap to design, so that every one can afford and build this by itself.

Arduino based 3D Printer

2. What is 3d printing?
 The technology used for printing physical 3D object from digital out is called
3D PRINTING, where three dimensional object is created by laying down
successive layers of material.
 It is also called RAPID PROTOTYPES.
 Essentially, the difference between 3D and 2D printers is that of printing
versus manufacturing.

3. Contents:-
1) Manufacturing Process
2) General Principles
3) 3D Printing Technology
4) Know your Printer..
5) Why 3D Printing?
6) Applications
7) Conclusions
8) References

4. The manufacturing process used here known as ADDITIVE MANUFACTURING.
 Creates a product through adding materials to the object.
 Adds material layer by layer until printing is finished.
MANUFACTURING PROCESS

5. 3D PRINTING TECHNOLOGY
DIFFERENT 3D PRINTING METHODS:
Selective laser sintering (SLS).
Stereo lithography.
Fused deposition modeling (FDM).
Laminated object manufacturing.

6.  The quick, clean and cost efficient development method of prototyping.
 CAD diagrams converted into design specific command which later released
the melted thermoplastic accordingly.
 This process is repeated layer by layer based on specific design coordinates.
 The molten material becomes a solid object as soon it is exposed to a cooler
environment.
FUSED DEPOSITION MODELING (FDM)

7. THE PRINTING CYCLE
a) Preparation
b) Printing
c) Finalizing

8. *CAD Software
Creo 2.0 (we are using)
CURA 15.04.03
CRAFT WARE 1.14
Programing Software:- ARDUINO IDE
*Don’t worry if you don’t know how to design on CAD…
*Website like Thingiverse, Grab2Cad will be your best design centre.
SOFTWARE USED:-

9. Mechanical:-
o Acrylic Frame
o Stainless steel Rods(7.95mm) & Threaded Rods(8mm.)
o Bearings (LM8UU)
o X,Y & Z Frame Assembly
o Spool Holder
o Nozzle(0.4mm)
o Heat Bed
o Filament(PLA-1.75mm)
o Machine Weight-13kg(with Filament)

10. Electrical & Electronics:
o Arduino Mega 2560
o Stepper Motors(6)
o Arduino Mega Shield
o A4988 Drivers
o End stops(3)
o LCD Controller
o SMPS
o Thermistors(2)

11. Arduino MEGA 2560
 THE MEGA 2560 IS A MICROCONTROLLER BOARD BASED ON THE ATMEGA2560 .
 54 DIGITAL INPUT/OUTPUT PINS (OF WHICH 15 CAN BE USED AS PWM OUT PUTS).
 16 ANALOG INPUTS.
 4 UARTS (HARDWARE SERIAL PORTS).
 16 MHZ CRYSTAL OSCILLATOR.

12. STEPPER MOTOR
 Stepper motors are DC motors that move in discrete steps.
 They have multiple coils that are organized in groups called "phases".
 By energizing each phase in sequence, the motor will rotate, one step
at a time.

13. ARDUINO MEGA SHIELD
 Shields are boards that can be plugged
on top of the Arduino PCB extending its
capabilities.
 easy to mount.
 cheap to produce.

14. THERMISTORS
Thermally sensitive resistor.
◦ Formed from semiconductor materials, not metals
◦ Often composite of a ceramic and a metallic oxide (Mn, Co, Cu or Fe)
◦ Typically have negative temperature coefficients.

21. In Conclusion
3D printing is an expanding technology which may soon start an industry in
which everyone has the possibility of being a manufacturer.
3D printing has a lot of possible benefits to society, although the products
created must be regulated.
