Laser Cutting & Engraving

Metal laser engraving is one of the most commercially valuable laser applications — and one of the most misunderstood. The most common mistake is purchasing a diode laser expecting it to mark metal, only to find the 450nm wavelength reflects off bare metal surfaces without effect. Metal requires a specific approach depending on the type of metal, the desired result, and the production volume. This guide explains what is possible with each xTool machine and which is right for each application. Why Metal Requires a Different Laser Wavelength Metal surfaces reflect visible light — which is why they appear shiny. The 450–455nm blue wavelength used by diode lasers reflects off bare metal rather than being absorbed. The exception is coated or anodised metals: anodised aluminium has a surface layer that absorbs the diode wavelength, which is why diode lasers mark anodised aluminium but not bare aluminium. Effective metal marking requires 1064nm — the infrared wavelength range where metals absorb rather than reflect. All fiber and IR lasers in the xTool range operate at 1064nm. Four Types of Metal Laser Processing Surface Marking (Oxidation) The most common application. The laser heats the metal surface to create a controlled oxide layer — a permanent, flush, scratch-resistant colour change. No material is removed. On stainless steel this produces marks from straw-yellow through blue and purple depending on temperature. On tool steel it produces deep black annealing marks. Used for serial numbers, QR codes, surgical instruments, tool identification, and branded metal products. Machines: All xTool fiber and IR machines. Speed and contrast increase significantly from the 2W IR (F1, F2) through 20W fiber (F1 Ultra) to 60W MOPA (F2 Ultra). Colour Engraving on Stainless Steel (MOPA) Standard fiber lasers produce oxidation in a limited colour range. MOPA lasers, with independent pulse width control, produce a full spectrum on stainless steel: vivid blue, gold, purple, red, and true black. Colours are permanent, produced by controlled oxide thicknesses, and require no pigments. Used for premium cutlery, trophy plaques, architectural hardware, branded surgical instruments, and luxury goods. Machines: F1 Ultra (20W fiber — good colour range), F2 Ultra (60W MOPA — full spectrum, deepest saturation, most consistent results). Deep Engraving (Material Removal) At sufficient power, the fiber laser removes metal material creating a physically recessed mark. Used for industrial part marking that must survive abrasion, tooling marks, and high-wear environments where surface oxidation would be removed in service. Machines: F1 Ultra (20W — light deep engraving on soft metals), F2 Ultra (60W MOPA — deep engraving on all metals including hardened steel). Thin Metal Cutting The F1 Ultra's 20W fiber cuts stainless steel up to 0.3mm, brass up to 0.4mm, aluminium up to 0.2mm. The F2 Ultra at 60W cuts up to 2mm on all three. Applications: metal stencils, jewellery blanks, decorative metal elements, and custom hardware previously requiring outsourced laser cutting.

The F1 Ultra's 0.002mm accuracy and 10,000 mm/s galvo speed make it the correct machine for rings, pendants, bracelets, and watch cases. Deep, permanent marks on gold, silver, platinum, and titanium at commercial production speeds. The F2 Ultra MOPA adds colour capability for premium pieces. Trophy and Award Manufacturing Stainless steel and aluminium plaques in high volume. The F1 Ultra processes these at 10,000 mm/s — a batch of 20 plaques takes minutes not hours. The F2 Ultra MOPA adds colour options for premium trophy work. Industrial Part Marking Serial numbers, QR codes, data matrix codes, and compliance marks on metal components requiring permanence and scan-readability. The F2 Ultra MOPA's 60W power and MOPA pulse control produce marks to industrial traceability standards. Market Traders and On-Site Personalisation The F1 Portable's 2W IR + 2kg weight + USB-C power makes it the only professional metal-capable laser that operates on battery at a market stall. For traders doing on-site metal personalisation — keyrings, tags, cutlery — this combination is unique in the market.

Every laser engraver or cutter uses one of a small number of laser technologies. The technology determines which materials the machine can process — not just which ones it does better. Understanding the physics of each laser type takes the guesswork out of machine selection and prevents costly mistakes when sourcing equipment for a specific application. How Lasers Interact with Materials — The Core Principle A laser is a focused beam of light at a specific wavelength. Whether a material is processed by that laser depends almost entirely on whether the material absorbs that wavelength. Glass is transparent to visible light but absorbs infrared. Aluminium reflects visible light but absorbs UV photons. Organic materials like wood and leather absorb broadly across wavelengths but particularly efficiently in the infrared range. This is why there is no single laser that processes every material equally well — the physics won't allow it. Diode Lasers (450–455nm) Modern desktop diode lasers use semiconductor lasers in the blue wavelength range. This wavelength is absorbed efficiently by most organic and dark-coloured materials and is the starting point for most xTool buyers. Processes well: Wood, bamboo, leather, cork, rubber, fabric, paper, dark and opaque acrylic, anodised aluminium, painted surfaces. At 40W, cuts basswood up to 25mm. Cannot process: Bare metal (reflected), clear acrylic (transmitted), glass (transmitted), white or very light acrylic (insufficient absorption). The galvo diode advantage: When a diode source is paired with galvanometer mirror steering rather than a moving gantry, engraving speed leaps from 400–600 mm/s to 4,000 mm/s. This is the architecture of the xTool F1 and F2 — the same diode wavelength at dramatically higher throughput. For high-volume engraving on organic materials, galvo diode is the most cost-effective production technology available. xTool diode machines: M1 Smart, M1 Ultra, S1 (enclosed, 20W/40W), F1 Portable (galvo), F2 (galvo). Infrared Laser (1064nm) At 1064nm, metal surfaces absorb the beam rather than reflecting it. This is the entry point to metal processing. IR modules at 2–5W (as found in the xTool F1 and F2) are specifically suited for marking bare metals — stainless steel, aluminium, brass, copper — and technical plastics and ceramics that diode lasers cannot mark cleanly. In practice, most IR module users are jewellers, metalworkers, market traders doing personalisation, and sign makers who need occasional metal marking alongside organic material work. The dual-source architecture (diode + IR in one machine) makes this accessible without purchasing separate machines. Fiber Laser (1064nm) Fiber lasers also operate at 1064nm but at significantly higher power than IR modules. Where a 2W IR module marks the surface, a 20W fiber laser engraves deeply, marks with high contrast and permanence, and cuts thin sheet metal. The xTool F1 Ultra cuts stainless steel up to 0.3mm and aluminium up to 0.2mm — capabilities impossible with diode or CO2 technology. Combined with galvo steering at 10,000 mm/s, the F1 Ultra processes metal jobs at speeds that make commercial production volumes viable from a desktop machine. Fifty engraved metal tags that would take hours on a gantry take minutes on the F1 Ultra. MOPA Fiber Laser MOPA (Master Oscillator Power Amplifier) fiber lasers provide independent control over pulse width and frequency — parameters that standard fiber lasers cannot separate. This unlocks three capabilities unavailable in standard fiber: Full colour spectrum on stainless steel: Different pulse widths produce different oxide thicknesses, producing different visible colours. Blue, gold, purple, red, and true black are all reproducible and permanent without pigments. True black on bare aluminium: Standard fiber produces grey marks on aluminium. MOPA's short pulses produce genuine black oxide — the industry standard for aluminium part marking. Coating-precise removal: MOPA removes coatings without thermal spread into the substrate — essential for electronics, precision instruments, and complex coated surfaces. The xTool F2 Ultra's 60W MOPA is competitive with industrial fiber systems at a fraction of the cost. For businesses where colour marking on metal is a core product offering, MOPA is the correct technology. CO2 Laser (10,600nm) CO2 lasers emit at 10,600nm — far infrared. Organic materials absorb this wavelength with extremely high efficiency. The result is decisive cutting power on wood, acrylic, leather, paper, and fabric that diode lasers cannot match at comparable wattage. A 55W CO2 cuts 18mm basswood in a single pass; a 40W diode requires multiple passes on the same thickness. CO2 also produces a flame-polished edge on cast acrylic — optically clear, smooth, requiring no post-processing. This is why CO2 is the standard technology for sign shops, furniture makers, and acrylic fabricators. Cannot process: Bare metal. The 10,600nm wavelength reflects off metal surfaces entirely. xTool CO2 machines: P2S (55W), P3 (80W with AI fire detection). UV Laser (355nm) UV lasers at 355nm operate through photochemical ablation — high-energy photons break molecular bonds directly, removing material without significant heat generation. This is categorically different from thermal laser processing and enables applications no other laser technology can achieve. 3D inner glass engraving: The UV beam focused inside transparent glass creates micro-fractures within the material volume — building 3D structures suspended inside glass or crystal objects. Crystal trophies, personalised glass blocks, and premium glassware decoration require this technology and nothing else. Heat-sensitive materials: Electronics, precision plastics, silicone, and coated surfaces that thermal lasers melt or discolour are marked cleanly by UV's cold processing mechanism. Ceramics and porcelain: Fired ceramic surfaces receive clean, burn-free marks without the thermal cracking risk of infrared lasers. xTool UV machine: F2 Ultra UV (5W, 15,000 mm/s via galvo, dual 48MP cameras).

Choosing a laser engraver or cutter is not as simple as picking a wattage and clicking buy. The xTool range spans eleven machines across five fundamentally different laser technologies — each suited to a different set of materials, workflows, and business models. This guide cuts through the confusion with a practical framework: understand your materials first, then choose the technology, then choose the machine. The One Question That Decides Everything: What Do You Need to Process? Every laser technology has a wavelength, and every material absorbs certain wavelengths and reflects or transmits others. A laser that works beautifully on wood will do nothing to bare metal. A CO2 laser that cuts acrylic cleanly cannot mark stainless steel. Before comparing machines, answer this: what materials will you work with most?

It's the most versatile machine at this price and the only desktop device that does full-colour printing without ink cartridges. €1,000–€2,000 — Serious Studio For pure diode power in a safe enclosed format, the S1 40W is the most capable enclosed diode laser available. For users who also need metal marking capability, the F1 Portable adds 2W IR and galvo speed at the same price point. The M1 Smart is the right choice if vinyl cutting is part of the workflow. €2,000–€5,000 — Small Business Production Two very different machines serve this tier. The P2S is for businesses whose primary material is thick wood, acrylic, or leather — sign shops, furniture makers, craft studios. The F1 Ultra is for personalisation businesses working with metals at volume — trophies, jewellery, branded merchandise. These two machines serve opposite ends of the material spectrum at the same price tier. €5,000+ — Professional and Industrial The P3 at €7,049 adds 80W CO2 power, larger build volume, AI fire detection, and built-in CO2 suppression — the choice for production CO2 operations where the machine runs all day. The F2 Ultra MOPA at €7,299 delivers 60W MOPA fiber capability — the right choice for industrial metal colour engraving, deep marking of hard metals, and applications requiring the full MOPA colour spectrum on stainless steel.
