6. The parts of a 3D printer
Choose a controller board:
R2C2 – Single board design
RAMPS – RepRap Arduino Mega Polulu Shield
Sanguinololu – single board design based on arduino
The aluminium frame
provides a stable printer
frame
Linear bearings for the
parts moving in the XYZ
axis

7. The parts of a 3D printer...
Stepper motors used to provide motion
along the printing axis and to drive the
filament to the printing head
The printing head
Buddaschnozzle v2.0
Try to get hold of another printer J

9. How to do your 3D objects?
• There exist several applications that you can use to design 3D models:
•
•
•
•
•
•
Solidworks
Autocad
Sketchup
Autodesk 123D
Blender
FreeCAD
In Hack-a-Day blog you can find thorough introduction tutorials for each
of the cited applications
Just google:
“Hackaday 3D Printering: Making a Thing”

11. 3D design for “normal” people
• Some other tools can be used to quickly turn an idea into a 3D model
• They already provide several 3D model templates as numbers letters and
common geometric figures
• Web browser based
• Very intuitive

12. Online repositories
• You can find lots of interesting 3D designs available in online communities
• www.thingiverse.com - is the largest community
• Due to problems related with the uploaded designs ownership new services for sharing
3D designs and projects are emerging
• www.thingtracker.net/
• www.youmagine.com/
