ATOMSTACK A70 Max

What the ATOMSTACK A70 Max can make

The ATOMSTACK A70 Max is a diode laser engraver: its blue laser engraves and cuts wood, plywood, leather, paper, cardboard, fabric and dark or opaque acrylic, and marks coated or painted metal. It cannot cut clear or blue acrylic, which lets blue light through, and bare metal needs far more power or a different laser.

It has an optical output of 77 W, a work area of 850 × 800 mm (33.5 × 31.5 in) and a top engraving speed of 400 mm/s.

The brand states that it cuts up to 28 mm of wood or plywood; thicker material takes several passes, and results depend on the material and air assist.

It works with a camera for positioning designs on the material, autofocus, support for a rotary attachment to engrave tumblers and other round objects, air assist for cleaner cuts and LightBurn and LaserGRBL software.

In the United States the ATOMSTACK A70 Max sells for $1,639, above the median of $399 across 86 diode laser engravers with a US price, among the premium models.

ATOMSTACK A70 Max safety and compliance

The ATOMSTACK A70 Max has flame detection and an emergency stop.

Every laser engraver makes smoke and fumes: run it with an exhaust to the outdoors or a fume purifier. Never cut PVC or vinyl, which release corrosive chlorine gas.

The brand states FDA compliance: laser products sold in the United States must meet the FDA's laser performance standard (21 CFR 1040.10) and be reported to the FDA, which issues an accession number.

Other compliance the brand states: CE (the manufacturer's declaration of conformity with EU product rules); FCC (US authorisation for the electronics' radio-frequency emissions); RoHS (restriction of hazardous substances in electronics (EU)).
