Laser Cutter

Cutting Acrylic
Last month, the LaserPro Application Lab introduced acrylic-cut samples and received tremendous response. This month, LaserPro will exhibit another exceptional acrylic-cut sample, using a 200W powered Laser to cut acrylic up to a thickness of 1" (25mm). Through techniques provided by the LaserPro Application Laboratory, you can effortlessly cut a magnificent acrylic sample with precision.

The LaserPro Application Lab has gathered a number of cutting techniques below for your reference.
1.Avoid acrylic flare up
Flare up during cutting could be caused by the large volume of dust generated come into contact with laser's high temperature, causing ignition/combustion. Increase the volume of air extraction will effectively impede this occurrence. Additionally, when using a moderate speed for cutting may also cause combustion easily. Turn on the nozzle head can effectively reduce this effect, but nozzle heads are not recommended for the applications of deeper cuttings (See example below).

Nozzle Head functions to aggregate air, but if used during deep cutting may cause surface acrylic scratch or damage (See below).

2.Setting Parameters with Precision
Setting parameters is of crucial importance. Speed, power, dpi and ppi can affect the overall output quality. Adapting appropriate parameters can effectively prevent coin-like markings or bottom-dragging episodes.

The new Gaia version has installed an updated Firmware which includes a "smooth" cutting function; this will improve the quality of finished cutting products.
*Laser pathway can also affect the quality of cutting, if you are unable ensure the quality of your laser pathway, please contact your local agent for further information.
 
3.Turn on Nozzle heads and increase volume of extraction

In order to prevent flare up, turn on nozzle heads and increase air extraction power.

 
4.Avoid parts from dropping before cutting completes
When cutting draws to completion, without any supporting base below, objects may appear to be hanging in the air, as shown below:
 Avoid parts from dropping before cutting completes
Laser's heating temperature may cause objects to melt, so even before laser carriage draws to completion, the acrylic parts may fall off first. Furthermore, when acrylic falls, the laser continues to fire and hits the cut object, which may damage the sample (Please see example below).
 Avoid parts from dropping before cutting completes

Here are several ways to avoid such occurrence:

.Place a supportive tool/base below the cut object to prevent

Use various sizes of screws to adjust the supportive height.
.Before cutting finishes, press [F1] to temporarily halt the machine, then paste the adhesive tape or double-sided tape to the cut segment, this will prevent the object from falling.

When pasting the adhesive tape, please take caution not to touch or move the cutting object in order to prevent displacement or shifting.
