Your Performance Series Glowforge can create individual prints up to 11 in x 19.5 in.
Your Glowforge Aura can create prints up to 12 in x 12 in.
Depending on the settings you choose, you may encounter a smaller print area.
Here's why:
When the head moves quickly, it needs additional room to slow down, so there are margins on the left and right. For prints with engravings and high-speed scoring operations, the margins are larger and the printable area is smaller. Manual settings will allow you to engrave in the margins, at the possible expense of lower quality. This feature is in beta. You can learn more about engraving in the margins here.
