From custom jewelry engraving to small-batch Etsy production, the LONGER Nano Duo AI delivers industrial-grade results from a portable, handheld body. Combining a 20W diode laser and a 2W infrared laser, it cuts and marks wood, metal, leather, ceramics, and more with 0.00199mm precision at 10,000mm/s. LONGER's built-in generative AI turns plain text prompts into ready-to-engrave designs in seconds—no design experience needed. Whether you run a home studio, a maker workshop, or a growing online shop, the Nano Duo is built for creators who demand both versatility and reliability.
Powered by LONGER's proprietary generative AI, the Nano Duo converts a simple text description into up to 10 ready-to-engrave design options in seconds—no design software or artistic skills required.
The 16MP AI Eye camera handles auto-focus, pattern auto-fill, and delivers a live on-material preview before the laser fires, so every batch run is perfectly consistent from the first piece to the last.
The Nano Duo is the only portable engraver with two independent laser sources built in. The 20W 450nm blue diode laser powers through wood, acrylic, leather, bamboo, fabric, and plastics at full speed, while the 2W 1064nm infrared laser precisely marks bare metals, anodized aluminum, and coated stainless steel without additional consumables.
Switch sources instantly to tackle virtually any project—no second machine, no extra investment.
Starting compact at 160×140mm, the Nano Duo's work area expands to a full 300×300mm using the industry-first dual-axis extension rail system—the largest working area available on any portable laser engraver, with zero loss in accuracy.
The integrated Smart Track Vertical Cut adds true vertical cutting capability up to 16mm deep at any position, opening up creative applications impossible on conventional portable engravers.
The Nano Duo reaches engraving speeds of 10,000mm/s—matching the output of machines five times its size—while holding motion accuracy to 0.00199mm across the entire work surface.
225-point automatic position calibration ensures razor-sharp edge definition on every job, whether you're engraving microscopic text on jewelry or cutting intricate vector patterns for signage.
An adaptive depth algorithm reads material color in real time and automatically adjusts laser head lift height, producing richly detailed 3D embossing effects with no manual parameter tuning needed.
The Nano Duo's compact, lightweight design supports full 360° handheld operation—take it directly to large furniture, vertical walls, curved surfaces, or any object too large or awkward to place on a flat table. True creative freedom, wherever inspiration strikes.
