When you go DiY way...

5 Imagine in a new dimension – 3D Printing

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 a lumin ium f rame provides a stable printer frame

8 Imagine in a new dimension – 3D Printing

•  You can find the part list and instructions to assemble a Prusa I3 model here

•  http://reprap.org/wiki/Prusa_i3_Build_Manual

•  The best deals on bearings, power supply, heat-bed, nozzle… are found on ebay

•  You can find complete printer kits already packed in many online shops

•  www.3dprinters-shop.com

How to do your 3D objects?

9

•  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”

An example

3D design for “normal” people

11 Imagine in a new dimension – 3D Printing

•  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

Online repositories

12 Imagine in a new dimension – 3D Printing

•  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/
