Portable Laser Engraver For Makers

The ACMER S1 is a compact Class 4 laser engraver that arrives pre-assembled and ready to use. It targets hobbyists and small-scale creators who need a portable machine for detailed engraving on materials such as wood, metal, acrylic and leather. Its 250x250x162 mm footprint and 1.5 kg weight make it easy to move between workspaces. Safety limit switches on the X and Y axes simplify positioning and resets.

3.5 W Optical Power And 0.04 mm Spot

The single specification that determines suitability is the 3.5 W (3500 mW) optical output combined with a 0.04 x 0.04 mm spot size at a 445 nm wavelength. This configuration defines the machine's ability to mark or cut a given material in a single pass. Buyers must match this power and spot diameter to the thickness and hardness of their intended workpieces.

130 x 130 mm Work Area At 10000 mm/min

The engraver provides a 130 x 130 mm (5.1 x 5.1 inch) working area, allowing multiple small items or a single detailed ceramic piece to be processed at once. An integrated laser scale assists precise project positioning within this boundary. Maximum engraving speed reaches 10000 mm/min for efficient throughput. The fixed frame size means larger panels or objects exceeding 130 mm in either dimension cannot be accommodated without re-fixturing.

Questions about this item

What does the 3.5 W optical power mean when the machine is running?

The 3.5 W diode delivers 3500 mW of 445 nm blue light, giving a 0.04 × 0.04 mm spot that can mark wood, leather, acrylic and coated metals at speeds up to 10000 mm/min.

How does the USB connection limit the workflow?

The engraver streams G-code over USB from LightBurn or LaserGRBL on a host PC; there is no onboard storage or wireless link, so the computer must stay connected during the job.

What clearances are needed on a desk for the 250 × 250 × 162 mm frame?

Allow at least 250 mm square of flat surface plus room for the 1.5 kg unit, its cable and any ventilation; the 130 × 130 mm work area sits inside that footprint.
