3D printing technologies:
atoms from bits

3D printing: becoming really popular
Source: http://www.shapeways.com/blog/archives/1582-3D-Printing-Hits-the-Peak-of-the-Gartner-Hype-Cycle-for-Emerging-Technologies.html
3D printing is now reaching the peak of the Gartner Hype Cycle.

Technologies: 3D printing

http://youtu.be/7QP73uTJApw
Refers to object made using ink jet technology in 3 dimensions by
layering powder and binding it with pigmented glue.

Technologies: Fused Deposition Modeling
http://youtu.be/h8XJUqHXgls
Fused Deposition Modeling (FDM) creates models by heating and
extruding a flament of plastic material.

Most of the 3D Printing community uses either ABS or PLA in either
3mm or 1.75mm diameters.

Technologies: Stereolitography
http://youtu.be/ygHVVKkJWlI
Stereolithography produces models by tracing a beam of UV light over a
photosensitive pool of liquid. Over time the part is lowered into the bath.

photosensitive pool of liquid. Over time the part is lowered into the bath.

Technologies: Selective Laser Sintering
http://youtu.be/lC0uVO_uT0s
Selective Laser Sintering (SLS) is similar to stereolithography replacing the
UV light with a laser and a vat of liquid with a powdered base.

Technologies: Laminated Object Manufacturing
http://youtu.be/FjxI2HszHzo
Laminated Object Manufacturing (LOM) machines cut and glue thousands of
sheets of material together to form solids, sometimes with standard A4 paper.

Electron Beam Melting (EBM) is similar to SLS except the process is far more exact
and capable of producing implant grade parts to be used in orthopedic surgery.

02: check your technology

Shapeways is a good resource.

03: Yes to moving parts and undercuts
But not with FDM!!!

03: FDM: use support material
PVA is the best option, it is water soluble.

3D printing: what could go wrong?
Too fast: we cannot achieve the full cylinder.
We had to slow the speed down and rise a bit the temperature.

3D printing: what could go wrong?
Too fast: the material does not have the time to solidify.
Also: too thin, and the roof collapses. On the right: slower and bigger detail.

Think about the speed
Each different material melt at a different temperature,
mixing them means slowing down the process.

Resolution
0.5 or 0.25 or 0.125 mm? Higher resolution =
more time for printing.

Skins and filling
You can add extra skins and reduce the
density of the flling, if you just need a shell.

123D Catch: result
See the orientation of the layers?

123D Catch: result
Support material (PLA) and object material
(ABS) mixed a bit.
