Information
Laser cutting is available at The Shop which houses a 40W Glowforge Basic and a 40W Glowforge Plus, which uses a beam of light the width of a human hair to cut, engrave, and shape designs from a variety of materials.
The Glowforge Basic bed can accommodate materials measuring 18” x 20.4”. The maximum printable area is 11 x 19.5”, and it’s reduced somewhat when the laser operates at high speed, as it can take space for the laser to decelerate. There’s a tray for materials that are up to 0.5” thick, or the tray can be removed to accommodate materials up to 2” thick.
You can design with any software that saves a PDF, including choices like Adobe Illustrator, Inkscape, CorelDraw, Adobe Photoshop, GIMP, Autodesk 360, and Sketchup. Glowforge can print JPG, PNG, SVG, PDF, and other file formats. To print a file, just drag-and-drop it directly in app, and then adjust the preview to your liking.
Note: All patrons must complete the Glowforge Laser Cutter Certification class before using the Glowforge. The Glowforge is only available for use by patrons 18+.
Accepted Materials
The Library does not supply materials for the Glowforge.
Patrons must confirm that their materials are compatible with a CO2 laser.
Accepted Materials
Materials appropriate for use in the Glowforge are dependent on the job that the machine will do. Due to the weaker power of an engraving, more materials are allowed for this than if the Glowforge is set to cut through a material.
- Materials must be ¼” (6mm) or thinner for a cut job
- Materials up to 2" can fit into the bed, but must only be engraved
Library staff must approve all non-Proofgrade material. We reserve the right to refuse material if we deem it to be unsafe or inappropriate.
Please note: The Shop does not allow the use of MDF (including Proofgrade Draftboard) in the Glowforge.
