All Main Campus Library facilities are open and operating at full capacity to Georgetown faculty, students, and staff. The Library will be closed to external community members and guests through December 2021, with limited exceptions. Find the most current information available on the Library's COVID-19 FAQ.

3D Printing

3D Printing Station: What you need to know

  • The Maker Hub has both FDM printers (Ultimakers) and an SLA printer (Formlabs)
  • You need an orientation from a Volunteer to use any of the 3D printers. See the Skills Calendar to find out when someone is available, or just drop in.
  • The Maker Hub does not charge for 3D filament for the FDM printers, for reasonable amounts. Due to the price of the resin, the Maker Hub charges SLA $25 per 50ml of volume printed with the SLA printer.

Reservations

The 3D printers in the Maker Hub operate on a first-come first-serve basis. We are currently not taking reservations for the 3D printers due to the challenge of predicting how long a print will take without the use of a specialized slicer sofware. If you are curious how long a certain model will take to print, please bring your model to the Maker Hub and speak with a Volunteer.

Things to keep in mind if you are considering a 3D printing project

  • Some supplies listed here may be out of stock, and we receive new filament and resin all the time. Please contact the Maker Hub to confirm supplies, or drop by to see what we have available!
  • If you are planning a 3D printing project, know that roughly one in four 3D printers will fail during the print. Please plan your project accordingly to avoid a failed print ruining your project!

Please see our Workshops and Events page for the dates and times of our Orientation and Introductory Sessions.

What kind of 3D Printing does the Maker Hub have available?

The Maker Hub has both FDM printers (Ultimakers) and an SLA printer (Formlabs) available for use by Georgetown students, staff, and faculty. Let's learn a little more about each of these technologies:

FDM 3D Printing

FDM, or fused deposition modeling, is the most common type of 3D printing found at the consumer level. FDM 3D printers work by extruding thermoplastic filaments, the Maker Hub primarily uses PLA (Polylactic Acid), through a heated nozzle, melting the material and applying the plastic layer by layer to a build platform. Each layer is laid down one at a time until the part is complete.

SLA 3D Printing

Stereolithography was the world’s first 3D printing technology, invented in the 1980s, and is still one of the most popular technologies for professionals. SLA 3D printers use a laser to cure liquid resin into hardened plastic in a process called photopolymerization.
