The acrylic is a very popular material for cutting and engraving laser is easy to engrave and cut and has a wide variety of colors and sizes.
The acrylic may be cast or extrusion. The first is used for engraving, as it leaves a whitish, tinged, leaving a clean etched with good contrast on clear material. The second etching leaves a clear but without producing a high contrast, so it is more appropriate if you just cut. This material has a lower melting point and produces a smooth and clean edge when cutting with the laser.
Acrylic printmaking techniques:
Most acrylic is recorded at the opposite, on the rear side of the material. This effect produces a clean and smooth as seen through the front of the surface. It is recommended to remove the top protective acrylic before recording.
Remember to cover the design before starting the recording. This is important because it is recording on the back of the material.
If you set a power level too high, you run the risk of distorting the material, leaving a recorded dirty, burned and irregular.
For a deep etch and clean, adjust the focus for the acrylic is slightly further from the lens (blurring). Lowering the approach approximately (1.5 mm) gives an etching cleaner, because when we get a point out of focus the laser beam thicker, producing a print of soft, clean appearance avoiding lines at the bottom of the engraving.
There are a number of acrylic products which are painted on one side to add color to the transparent part.
Laser machine can achieve a better cut effect with a relatively increased power. This combination allows the laser beam to fuse the edges of the cutting acrylic and produce a bright and polished.
Acrylics generally require only a last to be cut, but the thicker may require two or three strokes, depending on the potency of the machine. Sometimes you need to leave the protective mask on the back to absorb the rebound effect of laser cutting table. Acrylic is highly flammable and should never leave the machine unattended laser working, especially in the cut.
An MDF cutting edge is recommended dual large spiral cutting chip, which has two large capacity flute design manufacturers laser engraving machine of double edge, both the function of the chip, but also a good tool to achieve balance in high-density processing, no black, no smoke cover, long life.
(2) For machining precision CNC mill refreshments small relief, more serious is recommended round bottom.
3 cork, MDF, native wood, PVC, acrylic large deep relief process, we recommend the use of a single screw ball mill blade end.
4 in the following laser marking machine burr-free cutting, is recommended to use a single sheet, double-edged top and bottom of the cutters.
5 High densities, solid wood edge cutting teeth is recommended.
6 Wood processing wood laser cutter, is recommended double-edged cutter straight slot.
7 the use of the knife under the effect of products produced on the surface of the cutter, the treatment is not Rocker.
8 raw particle board and other board laser cutting machine multi-band is recommended.
