This page describes a laser engraving setting published for Titane at 2 mm, tested on a Sculpfun G9 fitted with a Infrarouge 2W (1064nm) source (1064 nm infrared, 2 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 Titane at 2 mm does not transfer to another thickness, nor to another source. A 1064 nm infrared rated 2 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 Titane, then adjust the speed rather than the power. Work with fume extraction and air assist, wear glasses rated for 1064 nm infrared, and never leave the machine unattended.
Sculpfun offers diode engravers with a good power-to-price ratio, extension kits and effective air assist. Their hallmark is the very fine focal spot on some modules, excellent for detail engraving but making focus critical when cutting.
Titanium is the metal of colour marking: depending on the energy applied, the oxide layer that forms takes blue, purple, gold or brown hues. A spectacular result, reserved for fibre sources.
Only a 1064 nm fibre source marks titanium. The colour does not come from a pigment but from oxide thickness: the power / speed / frequency combination sets it, and a 5 % drift changes the hue.
In practice you do not guess a colour: you engrave a test matrix on an offcut, note the parameters of each cell, and pick. This is the textbook use of a test grid.
Titanium conducts heat poorly: energy stays at the surface, which makes marking very crisp but also very sensitive to the slightest focus change.
Certified 1064 nm goggles are mandatory, lid closed: polished titanium reflects strongly. Titanium dust is also flammable — clean extraction and regular tray cleaning.
Colour marking is a very thin oxide layer: it resists corrosion well but not abrasion. Never polish a colour-marked part.
Degrease with alcohol before marking: a fingerprint locally changes the colour you get.
