Settings tips for Cardboard 1mm
low power, high speed; multiple fast passes beat one slow pass (fire risk). Never leave unattended. Test-cut a small square first: dial speed, not power, until it just cuts through — cleaner edge, less char.
Can your machine actually cut this?
Every laser here cuts cardboard, including the weakest diode, and it is the fastest material on the site. Because it needs so little power, the usual mistake is using far too much — which scorches the cut face brown instead of leaving it clean.
At 1 mm this is a single-pass, high-speed cut. The risk at this thickness is going too slowly: the heat has nowhere to go in a thin sheet, so it spreads sideways and you get a wide, scorched kerf instead of a crisp line. If the edge looks burnt, speed up before you touch the power. Thin cardboard also warps from the heat of a long job — cut in a different order, or tab the parts, if you see pieces lifting.
Buying the right sheet
Corrugated board hides the same trap as cheap plywood: the flutes between the liners are air gaps. The beam crosses a flute, spreads, and the cut can stop or wander. Solid greyboard and chipboard cut far more predictably than corrugated if the edge matters.
Safety — read this before the first cut
This is the highest fire-risk material on the site. Cardboard is thin, dry and porous, and it will sustain a flame happily. Never run a paper or card job unattended, even a short one, and keep the lid closed. Keep air assist low — a strong blast fans an ember into an actual flame rather than putting it out.
Getting a clean edge
Aim for the fastest speed that still cuts through in one pass. Multiple slow passes on card is how fires start, and the second pass rarely lands in exactly the same place anyway.
Cardboard 1mm FAQ
How fast can you laser cut Cardboard 1mm?
On a 100 W CO2 laser about 80 mm/s in a single pass. Diode lasers are roughly 5× slower (and need more passes above 3 mm). A 100 × 60 mm part (320 mm of cutting) takes about 4 s at 80 mm/s.
How much does laser cutting Cardboard 1mm cost?
Laser cutting is priced by machine time: cut length ÷ speed = time, × hourly rate (€60/h typical for a small shop) + setup + material. At 80 mm/s a 100 × 60 mm part is about €0.07 of machine time before material and setup.
What settings do I use for Cardboard 1mm?
Start from your machine's cardboard / paper preset, use gentle air assist, and do a test cut: if it doesn't cut through, slow down 10–15% before adding power. low power, high speed; multiple fast passes beat one slow pass (fire risk). Never leave unattended.
Where to buy Cardboard 1mm
Cardboard is the cheapest way to prototype a fit before committing plywood, and it is worth keeping a stack for exactly that.
