Change the mode on the black layer to Raster. Choose the laser cutter attached to the PC and click on the Properties button. This process will leave a ceramic (Cermark), polymer (nylon powder), or metallic (molybdenum disulfide lubricant) material permanently bonded to your workpiece.Ĭlick on File -> Print or, if in Rhino use the Print command. Most metals, ceramics, and glass can also be coated with different sprays that will bond with the surface of the workpiece after being struck with the laser. Do not use this process with galvanized sheets, due to the production of highly toxic gases. There will be minimal visible effect right away, but the engraved areas will weather and rust very quickly.
Cardboard, foamcore, and acrylic don’t lend themselves to laser engraving.īlued steel sheets can be laser engraved to remove the protective patina. Resinous woods (like pine, fir, cypress, and mesquite) and engineered products like MDF and chipboard show a high amount of contrast. Low density woods and paper products can create a deep relief, but tend to flare, which softens edges. High density woods, rubber, and linoleum show a sharp relief in depth. Wood, engineered wood products, solid paper products, rubber, linoleum, and leather all engrave very well. Keep in mind that subtle gradients tend to look smoothest at resolutions between 200-400ppi, but sharp lines and hatches will still be visible at the highest resolutions on the A laser cutters or the sub-basement laser cutter. The A studio laser cutters have a maximum resolution of 500ppi, the B studio laser cutters have a maximum resolution of 300ppi, and the sub-basement laser cutter’s maximum resolution is 1000ppi. If you want to send only raster information, Photoshop will suffice, but if you want to both engrave a raster image and then cut that same workpiece, Illustrator or Rhino will be necessary. In the case of Rhino and Illustrator, you can also send vector information to the laser cutter. For example, you can use Photoshop, Rhino, or Illustrator to send raster information to the laser cutter.
Our laser cutters receive information from printing, so users can set up their jobs in different graphics and drafting programs. The maximum power can still be adjusted in settings as a percentage, which will scale the power per pixel. A white pixel would result in a no pulse, and a black pixel in a maximum power pulse. Our laser cutters do this by turning each horizontal row of pixels in an image into a string of laser pulses where each pulse corresponds to a pixel with its power determined by how dark that pixel is. Raster engraving is a means of translating a pixel based graphic onto the surface of a workpiece.
