Hardboard is easily cut, engraved and marked by our BRM Laser machines, which is a big advantage to the traditional way hardboard is handled. It is very difficult to saw hardboard, but with a BRM Laser machine, it's very easy to handle hardboard and shape it the way you want to!
Slate is a binary material when it comes to laser engraving, i.e. it will only laser engrave with one colour, even if you use multiple passes or different laser power settings. Therefore you need to ensure your image is set up for black and white only, dithered and converted to a negative.Jan 24, 2022

MDF/Engineered woods 1/4" These are okay to use but may experience a higher amount of charring when cut. Paper, card stock thin Cuts very well on the laser cutter, and also very quickly. Cardboard, carton thicker Cuts well but may catch fire.
We can laser cut almost anything you can draw, including sharp angles, smooth curves, small screw holes, and complex lace designs, and we can also laser engrave text, logos, and photos on to your parts.

“K40” is a moniker for an affordable laser cutter that goes for about $300 to $400. There's no single manufacturer or official design specification for these machines, but they all work the same. They're usually in the 30-Watt range but are often upgraded to 40 Watts – hence the name “K40”.Feb 4, 2020

Laser etching is a process that creates marks on parts and products by melting their surface. It is part of the broader category called laser marking which also includes laser engraving and laser annealing. Highly versatile, it can be used with most metals.
Lasers release energy by emitting laser beams of specific wavelengths. When the beam hits the surface, the material reflects most of its energy. The remaining energy is absorbed and converted into heat. For laser etching, the material must absorb just enough energy to melt.
All laser marking methods have one thing in common: the laser beam is pulsed, releasing sudden bursts of energy at specific intervals. Within 1 second, a 100W pulsed laser can release 100,000 pulses. Each pulse contains 1 millijoule of energy and can reach 10,000W of peak power.
In today’s manufacturing, variants of this laser are used for laser etching, laser cutting and laser welding. 1964 – The CO2 laser is invented. Today, it is used for applications like laser marking and laser cutting. 1978 – The first laser engraver, although in its primitive form, is purchased.

In fact, the laser etching elevation can reach up to 80 microns whereas the laser engraving depth can reach 500 microns.
Etching is most commonly used to produce permanent markings such as data matrix codes, serial numbers, barcodes and logos.
Compared to engraving, laser etching creates marks without removing a significant amount of material. This makes laser etching more appropriate when dealing with very thin metal layers or fragile objects. Jewelry, particularly those made with precious metals or glass, are often processed using laser etching. Laser etching can also be done on ceramics, polymers, or materials that have been treated with metal plating.
This state of permanence is one of the major reasons why manufacturers choose to engrave marks instead of printing them on with ink . A laser engraved mark will remain legible even through several years of use, even in outdoor or heavy-duty conditions.
The standard depths needed for laser engraving are almost impossible to achieve with a single pass of a standard fiber laser. For this reason, multiple passes are almost always necessary. This significantly lengthens the processing time of a piece that is being marked with laser engraving. The time penalty is significant enough that manufacturers may think twice about using laser engraving for large-volume orders.
This makes laser engraving much more power-intensive compared to laser etching. This makes the expenses of running a laser engraver higher, both in terms of capital and operating costs.
Laser etching can typically be done on any material with just one pass of a laser beam. Since laser etching only affects a very small amount of material, it is a very fast process. This is a huge benefit to large-scale manufacturing or any process that requires a quick turnover. Compared to laser engraving, laser etching is about twice as fast.
