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 stereolithographyreplacing 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.
