xTool M2 3W 1064nm Laser Module Kit

Why 1064 nm Infrared Changes the Engraving Result

Diode lasers typically operate in the 450 nm blue-violet or 455 nm range. At those wavelengths, highly reflective metals such as gold, silver, and polished aluminium absorb very little energy, producing faint or inconsistent marks that fade with handling. An infrared beam at 1064 nm sits in the near-IR band where metallic absorption coefficients are substantially higher. The result is a localised thermal reaction that oxidises or etches the surface, producing marks that are visually darker, mechanically bonded to the substrate, and resistant to abrasion — without any coating or pre-treatment.

For plastics and rubber, the 1064 nm wavelength interacts differently with polymer chains than a blue diode does. Rather than surface ablation that can cause edge charring, the infrared energy produces a controlled colour-change reaction (foaming or carbonisation depending on the polymer), preserving edge sharpness on items such as phone cases, AirPods enclosures, and candle lids.

The comparison below illustrates the real-world difference between diode laser output and infrared laser output on the same metal pet tag surface — a direct demonstration of why wavelength selection determines final mark quality.

The contrast between the two outputs underscores the core value of the xTool M2 3W 1064nm Laser Module Kit — it does not approximate metal marking; it achieves it with the permanence required for jewellery, serialised labels, and branded accessories.

Tech Tip: When engraving bare aluminium with a 1064 nm IR module, run a test pass at 80–100 % power and 300–400 mm/min to assess the anodising depth before committing to a full design. Anodised aluminium marks faster than bare aluminium; reducing power by 20 % prevents over-ablation and maintains fine line detail in serialised text or QR codes.

Enhanced Marking on Plastics and Rubber

Standard blue diode lasers frequently burn rather than mark polymer surfaces, leaving discoloured edges and uneven contrast. The infrared wavelength of the xTool M2 3W 1064nm Laser Module Kit interacts with the molecular structure of plastics and rubber to produce cleaner, higher-contrast results without compromising the surrounding surface finish.

The image below shows real output on a range of polymer consumer products processed with this IR module, demonstrating the consistency of edge definition achievable across different plastic formulations.

Applications across this materials category include branded phone cases, promotional USB chargers, personalised candle lids, and rubber gaskets requiring part identification — all workflows that demand legibility at small text sizes and long-term mark durability.

Supported Metals and Compatibility with the xTool M2

The module installs directly into the xTool M2 enclosure, inheriting its XY motion system, software interface, and safety interlocks. No additional drivers or hardware modifications are necessary. Once installed, the 1064 nm beam path is pre-aligned to the M2's work area coordinate system.

The image below illustrates the module mounted on the M2 platform, actively engraving flasks and small metal identification tags — typical use cases for jewellery studios, electronics serialisation, and personalised gifts.

The supported metal range with this IR module is broad, covering the five most commonly requested materials in engraving and personalisation workflows.

• Iron
• Silver
• Gold
• Brass
• Aluminium

The image below shows finished engravings produced by the xTool M2 3W 1064nm Laser Module Kit across all five supported metals, demonstrating the depth and contrast achievable on each material type.

Brass and gold, commonly used in jewellery and award plaques, respond particularly well at 1064 nm — both metals exhibit high near-IR absorptance, enabling sharp, legible text and fine vector artwork at power settings that do not risk warping thin stock.
