This page describes a laser engraving setting published for Caoutchouc à tampon (laser rubber) at 3 mm, tested on a Vevor 60W CO2 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 Caoutchouc à tampon (laser rubber) at 3 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 Caoutchouc à tampon (laser rubber), 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.
Vevor distributes entry-level CO2 and fibre machines under its own name, often without detailed source documentation. This is the typical case where measuring with your own test grid beats trusting the advertised power.
Laser rubber is designed for the laser: it carves cleanly in depth, letting you make a complete rubber stamp in a single operation. It is also the smelliest material there is.
You engrave in negative and mirrored: the areas around the artwork are removed. Remember to flip the design before running — that mistake is a classic.
Depth matters more than contrast: about 1 mm of relief is needed for the stamp to print cleanly without ink bleeding. Achieve it with a high-power engrave in one or two passes rather than many light ones.
A slightly tapered wall lasts better than a vertical one: that is what a deep single-pass engrave naturally produces, as long as you do not slow down too much.
The smell is extremely strong and lingering, and the smoke carries greasy soot. Use only rubber sold as "laser rubber" (sulphur-free, chlorine-free) with effective extraction — and warn the people around you before starting.
Soot settles everywhere inside the machine: clean the lens and bed right afterwards.
Wash the stamp with soapy water and a toothbrush to clear soot from the recesses, otherwise the first prints will be grey.
