This document provides an overview of how to make your own 3D printer. It discusses RepRap open source 3D printers, the Prusa i3 model, technical specifications, common 3D printing materials like PLA and ABS, different 3D printing technologies, practical applications, the basic printing process, required materials and tools, assembly instructions, tips for use, and resources for support. The goal is to enable readers to build their own low-cost but high quality 3D printer.

by Minchee Lab

2. Agenda
● Introduction to your printer
● Materials
● 3D printing technologies
● Practical applications
● 3D Printing Process
● Resources
● On your mark…
● ...aftermath

3. RepRap Project
http://reprap.org/
● open source 3D printers
● FDM technology
● low-cost still good quality
● self replicating
● 51 different type of machines

4. What is Prusa i3?
● Prusa series
● i3: Iteration 3
Prusa Mendel
Your Printer

6. Prusa i3 Technical Specs
● 1 Nozzle, 0.4mm diameter
● Build envelope: 200mm x 200mm x 200mm
● Layer thickness: 0.1mm
● Filament diameter 1.75mm
● Reprap Firmware (Marlin)

● Can be hacked into CNC, auto leveling, add extra parts: LCD screen, print
chocolate...

7. Material
Key problem: printing time limited by the cooling down of the material
● PLA Polylactic Acid
● ABS Acrylonitrile Butadiene Styrene
● Nylon
● Flex...

14. Printing Process
optional post-processing: polishing

15. Pre-processing: Software
● 3D modeling - not for today ;-)
● Open Source software for Prusa i3:
○ Slicer: slic3r http://slic3r.org/
○ Printrun http://www.pronterface.com/

16. Enough talking !
Let’s start making !
Go to:
https://github.com/MincheeLab/MakeYourOwn3DPrinter/blob/master/doc/index.md

17. What you will need
● Acrylic frame: 3 parts
● 5 step motors
● 1 heated bed
● 1 bag of printed plastic parts
● 1 set of electronic: Arduino + RAMPS
● 1 set of mechanical parts + cables
● power supply
● rods...find out ;-)

18. Congratulations!
You did make a 3D Printer ;-)
48 hours later...

19. Motor power
● measure the DC Voltage
● around 1.5V ~ 1.7V
● if not, rotate clockwise

20. 3D Printer best friends...

21. How to mess up with your printer ;-)
● Filament in/out - always @hot temperature
● Bed leveling - enjoy the fun ;-)
● Hot-end jammed
● Extruder temperature - depend on material quality too...
● Room temperature

22. Printing Tips & Tricks
before reaching this quality...lot of fails...

23. Hack your printer don’t stop here, get creative with your printer features too!
