This page describes a laser engraving setting published for Silicone at 2 mm, tested on a Aeon Laser Mira 5 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 Silicone at 2 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 Silicone, 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.
Aeon Laser makes enclosed, water-cooled CO2 machines aimed at professional workshops: larger bed, honeycomb table and serious extraction. On these machines the rated tube power is genuinely available, which makes cutting speeds far higher than a diode at the same thickness.
Silicone cuts with a CO2 with clean, burr-free edges, which is hard to achieve mechanically on such a flexible material. It is the material of gaskets, moulds and technical mats. Careful: only pure silicone is suitable, not filled elastomers.
CO2 only: a diode has no effect on light-coloured silicone. Expect around 70% at 350 mm/min with a 40 W CO2 for 2 mm, in one pass.
The material is flexible and moves: hold it with a frame, magnets or low-tack adhesive. Silicone that shifts by a millimetre mid-cut ruins the part.
For engraving, stay moderate (25% at 2,000 mm/min): silicone melts and partly closes back up, so the design loses definition beyond that.
Common thicknesses: 1, 2 and 3 mm sheet. Beyond that, the edge becomes tapered and cutting precision drops.
Pitfall: composition. Many “rubber” sheets sold as silicone are actually neoprene, EPDM or a blend containing chlorine — the latter must be absolutely avoided. Only use silicone whose datasheet you know.
