ACMER K1 Enclosed Portable Laser Engraver – Class 1 Safe, 0.04mm Precision, 150×150mm, 2.5W / 3.5W / 7W / 12W

From engraving custom coasters and leather patches at home to producing personalized gifts and signage for a small business, the ACMER K1 delivers Class 1 enclosed safety, 0.04mm laser precision, and 10,000mm/min speed in a 2.4kg desktop footprint. Pre-assembled and ready to run with LightBurn, LaserGRBL, and ACMER software, it supports four swappable laser modules from 2.5W to 12W. The K1 is the ideal enclosed laser engraver for beginners, craft makers, and home studio operators who need safe, reliable, professional-quality results from day one.

Class 1 Enclosed Design – Safe for Home, Studio & Classroom

The K1's Class 1 fully enclosed body contains all laser activity inside the chamber, making it one of the safest desktop engravers available for indoor use — with no open-frame radiation risk.

A cover safety interlock instantly pauses the laser when the lid is opened, and a tilt induction sensor cuts power automatically if the machine tips beyond 13°. The built-in exhaust fan clears smoke and fumes during operation, keeping your workspace clean and safe for home offices, shared studios, classrooms, and family workshops alike.

Modular Power – One Machine from 2.5W to 12W

The K1 supports four interchangeable laser modules — 2.5W, 3.5W, 7W, and 12W — all using a 455 ± 5nm blue diode laser with beam-combining technology. Start with a lighter module for fine engraving on leather, paper, and wood, then swap in the 12W head for deep cutting without buying a second machine.

The 7W and 12W modules cut through 3mm basswood cleanly, slice thin acrylic, and handle cardboard, non-woven fabrics, and coated materials — giving you a single device that scales from hobby engraving to small-business production.

0.04mm Laser Spot & 0.01mm Repeat Accuracy

The K1's ultra-fine 0.04 × 0.04mm compressed laser spot captures hair-thin detail — photo portraits, fine text, intricate logos, and delicate patterns — with a level of sharpness that larger machines at this price cannot match.

0.01mm repeat positioning accuracy ensures every pass lands precisely on the same line, making the K1 reliable for multi-pass cuts, batch production, and detailed artwork. Engraving speed reaches 10,000mm/min, balancing precision and productivity across a full day's work.

Ultra-Portable 2.4kg – Take Your Creativity Anywhere

Weighing just 2.4kg with a compact body of 286 × 273 × 190mm, the K1 is built for creators on the move — equally at home on a studio desk, at a craft fair table, or in a school maker lab.

The durable aluminum profile frame and pulley-track motion system keep the machine rigid and accurate during transport and operation, while the 150 × 150mm (5.9 × 5.9 inch) work plate handles coasters, tags, keychains, patches, phone cases, and small signage with ease. Pre-assembled out of the box — just connect and go.

LightBurn, LaserGRBL & ACMER Software – One-Click Home Reset

The K1 supports LightBurn, LaserGRBL, and ACMER Studio — covering every workflow from free beginner software to professional production tools — on Windows, macOS, and Linux.

Built-in limit switches keep engraving within safe boundaries and prevent axis overrun, while the one-click "Go Home" origin reset instantly returns the laser head to its start position — saving setup time and eliminating misalignment between jobs. Every K1 is factory-inspected and performance-tested before shipping for consistent, reliable output.
