• ABS - not biodegradable , stinks!
• PLA – natural & biodegradable (from mais)
• PVA hydrosoluble support
• TPU (like PA flex….)
• PETG
• Policarbonato …
NEW Materials for 3D filament
Nylon Carbon
Recycled paper on an hydrosoluble
Matrix recyclable
Parts glued together by water wetting

It’s an Open World !
Knowledge is the only thing that grows when
you share it!

Open source developement is
• Decentralized
• Transparent
• Participatory
• No need to reinvent the wheel
• More people collaborate to solve
problems. Users as a group are
smarter than any one individual
• Students collaborate in knowledge
building- a world wide community
• Service Learning
Commercial approach is
• Top down
• Black box
• Secretive
Why should we pursue open source @school

OpenSCAD www.openSCAD.org
• free software available for Linux/UNIX, MS
Windows and Mac OS X.
• You don’t need to know CAD
• One of the primary benefits of OpenSCAD
is the ability to design customizable
content.
• These are designs which are parametrized
using parameters or top-level variables.

When you share an OpenSCAD design on Thingiverse, you can
have the web site customize your OpenSCAD file based on user
input.

The trick is use variables with special comments.
Here’s the mending plate file:
/* Really simple "mending plate" with two #6 holes -- I use this
to clamp a GT2 belt, but it probably could be used for anything. Al
Williams, April 2013 */
// Length of plate (mm) length=17; // [10:100] // Width of plate
(mm) width=6; // [5:100] //
Thickness of plate (mm) thickness=3; // [.5:20]
