What are the laser classes?
Laser class 1: inherently safe – no protective measures necessary.
Laser class 2: < 1mW, in the visible range, considered safe if they interact with eyes for < 0.25 seconds (e.g. laser pointer)
Laser class 3R: < 5mW, in the visible range (e.g. light curtains), avoid direct exposure
Laser class 3B: acute danger to eyes (e.g. laser in a DVD recorder), 5 – 500mW, diffuse reflection safe
Laser class 4: most dangerous class, danger from direct, reflected and scattered beams, plus: risk of fire
(Subclass “M” not considered here).
What is the difference between a laser cutter and a laser engraver?
Laser engravers and laser cutters are principally one device. The difference is in the respective strengths, the optional add-ons and the different wattages of the laser systems. The most suitable laser machine is decided by the primary application and the material to be lasered.
Which laser is ideal for cutting?
You can cut organic materials like wood, plastic and textiles with both the JustLaser Large Laser Cutter and the JustLaser Laser Engraver. The JustLaser Large Laser Cutter can also cut metals with a thickness of up to 4 mm. The JustCut range of products with an output of 1kW – 3kW from a fibre laser can cut metals with a thickness of up to 10mm.

Is it possible to use lasers on acrylic glass?
Acrylic is excellent to work with using a laser, regardless of whether you want to give the material a specific shape or give it an inscription. When a process is carried out correctly, the cutting edges have the same level of transparency and smoothness as all the other edges of the workpiece.
Is it possible to use lasers on wood?
Yes, you can engrave wood. Through laser cutting and laser engraving, you can give wood objects that “certain something”. Numerous types of wood can be processed according to your personal preferences or your customer’s wishes. Find more information about this here:
Is it possible to use lasers on polycarbonate?
Which woods are suitable for engraving?
Plywood, MDF, HDF, precious wood, real wood, veneers, press boards, cork and inlays are particularly good for engraving.
Can wood be cut with a laser?
The processes of laser engraving and laser cutting wood are not just used for creative designs, but also in the industrial sector. Whether it’s plywood, balsa, MDF, cork, HDF or multiplex boards, a JustLaser Large Cutter can cut numerous types of wood without any problems – from very thin boards through to 20mm-thick boards. The extraction system must be set up accordingly, especially for thick workpieces and / or if there is a large amount of glue.n.
Which laser should I use to cut wood?
On which materials can lasers be used?
Is it possible to use lasers on polycarbonate?
Is it possible to use lasers on polystyrene?
Yes, it is possible to quickly and easily use lasers on numerous foam materials – including polyurethane, polyethylene and polyester.
Which laser should I use for engraving?
Wood, acrylic, fabric, metal and many more – the laser engraver is the ideal entry point into the creative, productive and profitable world of laser engraving. Fibre lasers like that in the JustMark Lasermarker can mark and engrave virtually any metal – as well as a number of non-transparent plastics.
How does laser engraving work?
In contrast with mechanical engraving, where material is removed through scratching, piercing or chiselling, laser engraving is carried out with the help of the energy of a laser beam that heats the surface. Either up to evaporating temperature – at which point an engraving emerges – or well below it – at which point the wood reacts with the oxygen in the air and (usually) turns a dark colour.
Laser engraving
With laser engraving, a digitally-controlled laser engraver heats up the surface of a work material so much that it evaporates to a certain depth, creating a permanent and abrasion-resistant engraving. The smart laser technology in the JustLaser Laser Engraver wins people over due to its top levels of accuracy with repetitions without the need for an additional tool or any special technical skills.
Ablating
White marks can be made on anodised aluminium using CO2 lasers and fibre lasers. Setting the parameters for this is very simple. The chromophoric metal salts are thermally corroded by the rise in temperature, meaning that the inscription is white. Naturally anodised aluminum (i.e. with a metallic sheen but without any colour) and bare aluminium can be given dark or light inscriptions. With anodised aluminium, the extremely mechanically tough, chemical-resistant and non-electroconductive layer of aluminium oxide is retained.
With painted metals or plastic laminates (at least 2 layers), the coat of paint or top layer of plastic can be removed using a CO2 laser, often without leaving any residue behind.
