Laser at work: Using HDU board
High density urethane board does the job for thicker graphics

One of the interesting things we do with our laser is cut letters and graphics from high density urethane board. We’ve found that we can cut ½-in. Precision Board HDU with great results. It’s the only brand that we’ve cut successfully on our 35-watt laser.
We use HDU board when we want a thicker graphic than the typical 1/8- and ¼-in. acrylic graphics we frequently cut on the laser. We also often use it when we are building a sign to ship elsewhere. A ¼-in. acrylic letter mounted on ¼-in. acrylic spacers can get snapped off during shipping, but the HDU letter is bonded to the surface and will stay put.
