3D PRINTING: a tutorial
Marco Cattani & Niels Brouwers
Why this tutorial?
Research in Embedded system
Custom hardware custom enclosure
System deployments novel solutions
Is 3D printing is a tool that can empower our research?
3D printing is becoming very popular
Different technologies
Fused Deposition Modeling (FDM)
Creates models by heating and extruding a flament of plastic material
Materials: PLA, ABS (diameter
Different technologies
Stereolitography
Produces models by tracing a beam of UV light over a photosensitive pool of liquid. Over time the part is lowered into the bath.
Very expensive resin
Different technologies
Selective Laser Sintering (SLS)
Similar to stereolithography replacing the UV light with a laser and a vat of liquid with a powdered base.
From stainless steel to gold, ceramic, rubber and plastic (stainless steel costs ~ $10/cm3)
Different technologies
Solar Sinter Project
Use the sun rays instead of a laser
Different technologies
Laminated Object Manufacturing (LOM)
Machines cut and glue thousands of sheets of material together to form solids, sometimes with standard A4 paper.

Green technology?
Filabot
A 3D plastic extrusion system for mostly any type of recyclable plastic, to make usable 3D printing filament by grinding, melting, extruding the plastic filament.
What can be printed?
Organs (organovo.com)
Food (Choc Creator)
Music instruments (kalimba)
Furniture (lamps)
Clothing and shoes
Optics (from Disney Research)
What can be printed?
Velcro
The velcro is printed with 0.3mm ABS with a MK6 extruder on a Makerbot.
What can be printed?
Flexible grids
Done with a Grasshopper defnition that used the grid components to create a set of flexible triangular, square, and hexagonal grids.
