Laser Cutter

The Glowforge Plus laser cutter is available for community member projects. The Glowforge Plus is a Class 1 laser product which contains an embedded Class 4 laser. The Glowforge Plus 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. SVG is the best format for maintaining design layers. Glowforge can print JPG, PNG, PDF, and other file formats. 

The Library reserves the right to reject projects based on content or copyright. Commercial projects are not accepted at this time. Same day projects cannot be guaranteed and project completion time will vary.
