CORONAVIRUS UPDATE: The library is closed effective Tuesday, March 24th.
Continuing services will include: access to online materials; reference, class or research consultations; and assistance with securing expanded online access to curriculum-based and/or research materials. For more information see the Georgetown Libraries COVID-19 Updates and Resources page and the Library's COVID-19 FAQ.
"CNC" stands for "Computer Numerically Controlled," and CNC Fabrication means "using computers to control machines to make stuff."
By using software to control hardware, we can easily turn our ideas into physical objects, test them, tweak them, and try again. This is called "Rapid Prototyping," and is the foundation of contemporary design.
The Maker Hubs CNC machines include 3D printers, a Laser Cutter, and a Vinyl Cutter. Each machine is best suited for different types of fabrication. Take a look at the pages for individual machines to learn more.
3D Printing: What you need to know
- FDM 3D Printers are the MakerBots, Ultimakers, and Monoprice Select
- SLA 3D Printer is the FormLabs (orange top)
- To learn about 3D printing, talk to someone with the 3D printing skill. See the Skills Calendar to find out when someone is available, or just drop in.
- Use of 3D printers requires a reservation. Talk to a volunteer or use the chat system to make a reservation.
- Have your 3D STL file ready to go by the start of your reservation.
- Overestimate your 3D printing time by about 10%.
- If you don’t make a reservation, and your print overlaps with someone else’s reservation, your print will be cancelled.
- Bear in mind that roughly 1 in 4 3D printers will fail. Plan your project accordingly.
- Your reservation may be delayed if another reserved print goes a little long.
- You need a safety orientation to use the FDM printers
- There is no charge for 3D filament for the FDM printers, for reasonable amounts.
- Talk to the Maker Hub Manager to use the SLA printer
- SLA printing costs $25 per 50ml of volume printed.
- SCRAP PLA FDM filament goes in the SCRAP PLA bin.
- Completed prints go in the COMPLETED PRINTS bin.
- Some supplies listed here may be out of stock, and we receive new consumables all the time. Please contact the Maker Hub to confirm supplies, or drop by to see what we have available.
Please see our Workshops and Events page for the dates and times of our Orientation and Introductory Sessions.
