Fused Deposition Modeling (FDM): Creates a 3D object layer by layer with thermoplastic filament heated to its melting point and extruded from a 3D printer's nozzle. FDM is the most common printing technique.
Selective Laser Sintering (SLS): Creates a 3D object with a laser that fuses together particles of powdered materials.
Continuous Liquid Interface Production (CLIP): Think of the film Terminator II. A digital light projector bombards a reservoir of liquid plastic with UV images to create a solid, 3D object.
Stereolithography (SLA): Creates a 3D object with a UV laser that hardens liquid plastic or resin in a reservoir.
There's a variety materials with which to print. For example, our Ultimaker 2Go uses Polyactic Acid plastic filament (PLA), a bio-degradable plastic often made from cornstarch or sugar cane.
Another common plastic filament is Acrylonitrile Butadiene Styrene (ABS), which is oil-based and with a higher melting point and environmental impact. Think LEGO bricks.
Our Ultimaker 3 Extended prints in either PLA and ABS.
Here is a glossary of additional 3D printing material.
The Coocheer 3D drawing pen - 3D pen of choice for the CSCC Library!
3D pens are small, handheld devices. They're similar to hot glue guns, allowing users to "draw" in 3D by extruding a thin line of liquid PLA or ABS filament, which instantly hardens and creates a 3-D object. Most pens allow for adjustment of speed and temperature and to quickly colors.
You can use scanners to create digital files of objects to manipulate.
