Information
Laser cutting is available at The Shop which houses a 45W Glowforge Pro HD 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 Plus and Pro HD bed can accommodate materials measuring 18” x 20”. 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 create very simple designs within the Glowforge web interface, or you can design and export a digital file to upload at the time of your equipment reservation. There are dozens of paid and open-source software options to choose from, such as Inkscape, Illustrator, Photoshop, Canva, or CorelDraw. PowerPoint and Keynote also work! Before you start designing, make sure you’ll be able to export your file in a format that is compatible with the Glowforge interface. The Glowforge can print .JPG, .PDF, .PNG, .SVG, and .DXF file formats.
Connecting to the Glowforge machine is simple. You’ll just need a laptop or tablet with internet access, and an up-to-date version of Chrome, Firefox, Safari, or Microsoft Edge. 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+. Click here to make an online reservation to use the Glowforge.
Glowforge Safety Certification Class
Glowforge Laser Cutter Certification Class: Learn everything you need to know about creating files for the Glowforge laser cutter and using the machine.
This class will go over the basics of laser cutting, safety procedures, and the accompanying app.Glowforge.com interface. Students will then be required to design and successfully cut a small and simple project that incorporates the skills and knowledge covered.
Prerequisites: Basic MAC or PC skills; previous knowledge of design software is recommended.
Accepted Materials
The Library does not supply materials for the Glowforge and 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
- The maximum height with the crumb tray is .5 inches. You can remove the crumb tray and engrave items taller than 2.0 inches, but you must put something underneath the piece to bring it to within the 2.0 inch range of the laser head. Please notify Shop staff if you plan on removing the crumb tray.
Library staff reserve the right to refuse material if we deem it to be unsafe or inappropriate.
