LaserPecker 4 Dual Laser Engraver: fibre and diode lasers explained

The LaserPecker 4 (model LP4) is a compact desktop laser engraver that carries two lasers: an infrared laser and a diode laser. The aim is to let one machine mark metal and plastic as well as wood, leather, glass and ceramics, for hobby projects, small businesses and personalised gifts.

Two lasers, two jobs

Different materials respond to different wavelengths. LaserPecker says the infrared laser suits metals and plastics, while the diode laser is for wood, leather, glass, ceramics and similar materials. Diode lasers are common in entry-level engravers, and infrared lasers are the type often used for marking metal. Having both in one body reduces the need for a second machine.

LaserPecker also says the diode laser can cut wood up to 8 mm thick and acrylic up to 5 mm, and that the machine can remove rust and work on overglaze.

Work area and accessories

The working size is 160 x 300 mm. LaserPecker offers a Rotary Extension for round and curved items such as bottles, mugs, tumblers, rings and vases, and a Slide Extension for working on several pieces or longer objects. The listing is not clear on what is included with the machine, so confirm which extensions are in the package.

The structure is adjustable to different angles, which the brand says lets you engrave objects of varied shapes and heights. The unit measures about 14.6 x 10.5 x 12.0 inches (roughly 37 x 27 x 30 cm).

Accuracy and speed

LaserPecker rates the engraving accuracy at 8K (1270 dpi) and uses galvanometer technology, in which small mirrors steer the beam quickly. The brand quotes a speed of up to 240,000 mm/min. As with any such figure, real speed depends on the material, the depth of mark and the settings you use, and fast settings usually mean lighter marks.

Software

A free app for smartphone and PC handles design and setup. The brand lists multi-layer editing, variable engraving settings, import of multiple file formats and recommended settings for different materials. The LP4 is also compatible with LightBurn, a design package with more advanced controls.

Safe use

Laser engravers can harm eyes and start fires, and some materials give off harmful fumes when burned. Follow the manual on eye protection, ventilation and which materials to avoid, and never leave a running machine unattended.

Who it suits

It suits makers, small shops that personalise items for customers, jewellery and craft makers, and hobbyists who want to try both metal marking and wood or leather work.

What to check before you buy

• Materials: confirm that the materials you plan to use are supported and safe to engrave.
• Work area: 160 x 300 mm may be small for large panels.
