Hardboard

Material Overview

Our 3 mm hardboard sheets are smooth on both sides and perfect for laser cutting. Made from compressed wood fibers (High-Density Fiberboard), this brown sheet material has a high density and ensures a neat result. Thanks to the smooth surfaces, you avoid splinters and they are ready for further processing such as engraving, painting, or printing.

During laser cutting, a dark brown residue forms around the cut – the protective film limits contamination on the surface. Ideal for both hobbyists and professionals seeking dimensional stability and a clean finish.

✔ Highlights

✔ Laser compatible – cuts neatly with CO₂ lasers
✔ Ready to use – can be used directly in the laser
✔ Smooth surface on both sides – no finishing required
✔ High density – prevents splintering or burning
✔ Cutting width only about 0.2 mm – fine detail possible 
✔ Lightweight and easy to work with (sawing, drilling, milling, sanding) 
✔ Eco-friendly – made from wood fiber leftovers
