Material overview
Our 3 mm hardboard sheets are smooth on both sides and excellent for laser cutting. Made from compressed wood fibers (High-Density Fiberboard), this brown sheet material has a high density and ensures a clean result. Thanks to the smooth surfaces, splinters are prevented, making the sheets instantly ready for further processing such as engraving, painting, or printing.
During laser cutting, a dark brown residue forms around the cut – a protective film limits contamination on the surface. Ideal for both hobbyists and professionals looking for dimensional stability and a clean finish.
✔ Highlights
✔ Laser compatible – cuts cleanly 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
✔ Kerf width only approx. 0.2 mm – fine details possible
✔ Lightweight and easy to process (sawing, drilling, milling, sanding)
✔ Eco-friendly – produced from wood fiber surplus
Which laser source is this material suitable for?
✅ Suitable for CO₂ lasers
✅ Suitable for diode lasers
Applications
For hobbyists:
Use for miniatures, wall decorations, organizers, personalized signs, or boxes. The smooth hardboard base responds well to paint, markers, and stains.
For professionals:
Perfect for prototypes, scale models, displays, packaging, furniture construction, technical parts, and protective panels. Thanks to its dimensional stability and workability, it is highly versatile.

Frequently asked questions about Hardboard
How do I know if a material is suitable for my laser cutter?
Every product page indicates which types of lasers the material is suitable for (e.g. CO₂ or diode lasers). If you are unsure, feel free to contact us. We are happy to advise you.
Are the sheets exactly the specified size?
We cut or saw the sheets as accurately as possible. Minor deviations of a few millimeters may occur due to the sawing or cutting process.
Can I return materials?
Yes, unused and undamaged materials can be returned within 14 days. Custom-made or specially ordered sheets are excluded. You can find more information on our returns page.
What are the shipping costs?
Shipping costs are calculated automatically during checkout based on size, weight, and destination.
