What is 3D printing?
3D printing is the process of producing a physical object directly from a digital 3D file. ETS printers are all of the FDM (Fused Deposition Modeling) class of printers which create objects by additively laying down successive layers of material until the entire object is built. The two primary materials for printing in the Studio are PLA (a corn-derived biodegradeable plastic) and ABS (AKA 'LEGO' plastic).
Who can use the 3D Printers?
Any Binghamton University students, staff and faculty may use the 3D printers provided that they have first completed the 3D printer certification course.
How does 3D printing work?
It all starts with a virtual 3D descriptor of the real-world object you want to create. This can be created by hand using 3D modeling software or scanned using a 3D scanner (both available for use in at ETS). Increasingly common are online communities like Thingiverse.com where virtual models of 3D objects can be shared and downloaded in an open community.
Once finalized, the object needs to be 'sliced' in a process where it is converted into GCode; a language which instructs the printer how to construct the object layer-by-layer, and contains all of the information regarding the object's infill (what it looks like inside), ultimate size, and other such properties.
In the studio, we have the following FDM printers available for use by students and faculty:
- Makerbot Replicator 2X
- UPrint SE Plus

The 3Doodler is a portable extrusion-based 3D printer that you control with your hand. Unlike the 3D printers above, the 3Doodler does not use stepper motors and computers to print the model. Rather, it extrudes the same plastic filament, but your arm controls where and how the filament is extruded.
