Material safety statements from the sources
Acrylic
The cited source documents conditions for acrylic. They apply to every acrylic row on this page.
- Fire:
Experience shows that vector cutting with a laser is most likely to produce an open flame. In particular, acrylic has proven to be extremely flammable in vector cutting.
(xTool, S1 Safety First (Important), read 2026-09-21) - Fire:
Many materials are susceptible to igniting; however, acrylic (in all its forms), has shown to be especially flammable when vector cutting with the laser.
(Epilog Laser, Reducing Fire Hazards with your Laser, read 2026-09-21) - Fire:
Utilizing the Air Assist feature will reduce the instance of flare-ups when working with flammable materials such as acrylic and wood.
(Epilog Laser, Reducing Fire Hazards with your Laser, read 2026-09-21) - Ventilation:
Ensure that the workspace is well-ventilated so that the generated smoke can be discharged in time.
(xTool, S1 Safety First (Important), read 2026-09-21) - Fire:
It is forbidden to leave it unattended while the machine is working.
(Creality, Creality Falcon2 (12W/22W/40W) User Manual, read 2026-09-21) - Check the composition:
Do not engrave or cut any unknown materials.

Source-documented settings for acrylic on the OMTech Polar 350
Manufacturer-published reference parameters, not tested by CutChart
Match the machine, material and operation before reading a value. Speed is shown in the source unit and in mm/s, rounded to two decimals. Each row names its publisher and the date we read the document. A field the publisher does not print is shown as not specified; CutChart never fills it in.
| Machine | Thickness | Material as printed | Operation | Speed | Power | Passes | Fields the table does not print | Source and status |
|---|---|---|---|---|---|---|---|---|
| OMTech Polar 350 | 3 mm material | Acrylic | cut | 35 mm/s (35 mm/s) | 90% | Not specified by OMTech |
| OMTech, read 2026-09-21. Manufacturer-published reference parameters, not tested by CutChart; reviewed 2026-09-21. |
| OMTech Polar 350 | 3 mm material | Acrylic | engrave | 500 mm/s (500 mm/s) | 50% | Not specified by OMTech |
| OMTech, read 2026-09-21. Manufacturer-published reference parameters, not tested by CutChart; reviewed 2026-09-21. |
These are each publisher's own parameters for its machine and material. CutChart has not run them. Confirm the exact material, focus, air assist and lens with the manufacturer before use.
Read the evidence in context
Our source process explains the checks behind a row. The speed converter changes units; it does not move a setting to another machine. Check power labels with the optical-watt decoder, and read the safety limits before choosing a material.
Common questions
Can I use a row on another machine?
Each row belongs to the stated machine and configuration. A matching wattage or material name does not establish a setting for another machine.
Why are some fields marked not specified?
The publisher’s table prints speed, power and thickness, and sometimes passes, but not air assist, focus or lens. CutChart shows each unprinted field as not specified rather than filling it in.
Why are some combinations absent?
CutChart publishes a row only when its source, exact machine, material, operation and a sourced material-safety statement meet the reference requirements. An absent row is an unknown answer.

Publication date not printed by xTool · Read · Captured
A high-density laser beam is used by the device to irradiate the material to be cut or engraved, so as to heat up the material surface and vaporize the material without burning. But most materials are inherently flammable and may be ignited to form an open flame that can burn down the device (even if it is made of flame-retardant materials) and its surroundings. Experience shows that vector cutting with a laser is most likely to produce an open flame. In particular, acrylic has proven to be extremely flammable in vector cutting.

Do not engrave or cut any unknown materials. Vaporization or melting of many materials, which include but are not limited to PVC and polycarbonate, may release harmful smoke.
