Glowforge Tech Specs

Three models to choose from

Glowforge pro air filter
Glowforge Pro + Air Filter

Our Pro model is designed for frequent, shared use, like a makerspace. It comes with upgraded optics, tube, and cooling. The passthrough lets you use long materials but requires additional safety precautions. Includes an Air Filter.

Glowforge basic air filter
Glowforge Basic + Air Filter

Adding the recommended Glowforge Air Filter lets you run your Glowforge anywhere without venting.

Glowforge basic
Glowforge Basic

Our standard model can create everything shown on the Glowforge home page and is perfect for home, hobby, or occasional shop use. It needs ventilation via the provided 4″ diameter (10.2cm) hose. We recommend putting the hose out a window.

What’s an Air Filter and who should buy one?

Lasers normally require some ventilation via a small tube out a nearby window. Our optional Air Filter that sits under Glowforge and ventilates using HEPA filters and charcoal, meaning no outside ventilation is required.

  • 6 month warranty for Glowforge Basic, 12 month warranty for Glowforge Pro
  • If your machine is defective when you receive it, we’ll make it right immediately.
  • For US customers, if it develops a problem later that’s our fault, we’ll either (at our option) ship you the parts that need to be replaced along with detailed instructions, or ship it back to us for repair or replacement – in either case, for free, including shipping.
  • For international customers, parts and repairs are free, but shipping is not included.
  • The warranty covers everything except the air filter cartridges.
  • Unfortunately, if you modify your firmware, we can’t cover your Glowforge under warranty (because it’s easy to break your Glowforge by modifying your firmware!)
