Atomstack A20 Pro FAQ
How fast does the Atomstack A20 Pro cut 3 mm plywood?
About 6 mm/s. Cutting a 100 × 60 mm part (320 mm of cut) takes roughly 53 s of machine time on the Atomstack A20 Pro.
Can the Atomstack A20 Pro cut clear acrylic?
No. The Atomstack A20 Pro is a diode laser (~450 nm) and passes straight through clear acrylic. It can cut dark, opaque acrylic. Use a CO2 laser for clear acrylic.
What is the Atomstack A20 Pro bed size?
The Atomstack A20 Pro has a 400 × 400 mm work area (15.7 × 15.7 inches). That is the largest part it can cut in one pass without repositioning the material.
How much does it cost to run the Atomstack A20 Pro?
Laser cutting is priced by machine time: cut length ÷ cutting speed × passes = time, then time × hourly rate + setup. At €60/h a 100 × 60 mm plywood part costs about €0.89. Use the calculator to price your own file.
How much does the Atomstack A20 Pro cost?
~€500–600 as of August 2026, for the machine alone. Budget extra for extraction, a decent air assist and material. Street prices move, so treat this as a starting point and check the seller before you quote work on it. Full reasoning in our budget laser engraver guide.
