This page describes a laser engraving setting published for Corian / surface solide at 12 mm, tested on a Universal Laser Systems VLS3.60DT fitted with a CO2 60W source (10,600 nm CO2, 60 W). It states the exact machine, source, material, thickness and operation of the test; power, speed and number of passes are shown with a Premium pass.
Why those four facts matter: a engraving setting that works on Corian / surface solide at 12 mm does not transfer to another thickness, nor to another source. A 10,600 nm CO2 rated 60 W does not deposit the same energy as a stronger module, and the speed has to be adjusted accordingly. Copying a number without checking those four points is the first cause of a ruined part.
Published by LaserSettings (estimation). No other workshop has confirmed it yet: treat it as a starting point, and confirm it from your account if you reproduce it.
No photo comes with this setting yet. If you reproduce it, publish yours from your account: a picture of the result is worth more than a line of numbers.
Recommended routine before running the part: clean the lens, redo the focus, engrave a small test grid on an offcut of the same Corian / surface solide, then adjust the speed rather than the power. Work with fume extraction and air assist, wear glasses rated for 10,600 nm CO2, and never leave the machine unattended.
Universal Laser Systems builds modular CO2 and fibre platforms where source, lens and table change with the job. Settings are inseparable from the configuration: same machine, different lens, different result.
Corian is a mineral solid surface (acrylic resin filled with aluminium trihydrate), used for worktops and signage. A laser does not cut it, but engraves it remarkably well: the engraved bottom turns matt white, highly legible on coloured Corian.
CO2 only, and engraving only: around 60% at 1,500 mm/min with a 40 W CO2. The mineral filler does not vaporise, it whitens: that whitening is what creates the contrast.
Several light passes give a more uniform white than one strong pass, which digs in and leaves an uneven, greyish bottom.
Corian offcuts are common at kitchen fitters: an almost free material for the workshop, ideal for interior signage.
Common thicknesses: 6 and 12 mm. Cutting is done with a saw or a router, never a laser: the beam does not get through the mineral filler.
Pitfall: the white dust produced by engraving settles in the recesses and misleads you about the contrast. Blow or brush before judging the result.
