The AtomStack A20 Pro 1064nm is a 20W infrared fiber laser engraver designed for precision metal work. With a 1064nm wavelength and an ultra-fine 0.03 × 0.06 mm laser spot, it delivers fast, high-accuracy engraving and supports one-pass cutting of 0.2 mm aluminum.

A 400 × 400 mm workspace and speeds up to 400 mm/s ensure efficient production, while power-loss resume, modular 15-minute installation, and rapid laser rust removal add flexibility and reliability — a compact, professional solution for serious metal engraving.

The World's First Professional 1064nm 20W Frame Type Fiber Laser Engraver

20W Fiber Laser Power: The world's first 1064nm wavelength infrared fiber laser marking and engraving machine with optical power up to 20W.
Multi-Material Application: The AtomStack 20W infrared fiber laser engraver and cutter can be applied to all daily metals (copper, iron, aluminum, zinc, silver, etc.) and plastics for high-speed, fine engraving. It can also engrave black acrylic, leather, ceramics, and rock.
Metal Cutting: With 20W fiber laser power and 0.03*0.06mm ultra-fine spot, AtomStack A20/K1 Pro 1064nm can easily cut 0.2mm aluminum business cards by one-pass.
Resume Engraving: In the face of accidental interruption of the work, AtomStack self-developed intelligent motherboard can realize the power failure to continue carving function, continue to work without wasting materials.
Ultra-Fast Working Speed: the machine adopts the movement structure of optical axis + linear guide, more can realize 400mm/s ultra-high-speed high-precision operation, and the engraving accuracy can reach 0.01mm under the limit speed, which greatly improves the working efficiency.
Fiber-Optic Conduction: The laser energy transmission adopts the fiber-optic conduction method, which can greatly improve the energy transmission efficiency and reduce the energy transmission loss.
Relief Engraving: The 1064nm infrared laser is well suited for deep engraving on neat slate planes, demonstrating a relief effect.
New Robust Structure: This laser marking machine features an optical axis and linear guide movement structure, a modular design, and a quick 15-minute installation.
Rust Removal: The AtomStack A20/K1 Pro 1064nm fiber laser engraver and cutter is very suitable for removing the surface rust layer from metal. It can quickly perform laser rust removal on metal.
Safety Protection: AtomStack prioritizes the safety of your work. This laser marking and engraving machine is equipped with a physical switch key, sensitive gyroscope displacement detection, limit protection, and various other safety features.
