Quick Answer: The best laser engraver for metal in 2026 is the xTool F1 — a compact fiber-plus-diode unit that marks bare stainless, brass, aluminum, and titanium while still engraving wood and leather. For heavier, faster industrial marking, the Monport 30W fiber laser is the pick, and on a budget the xTool S1 (40W diode) with marking spray handles coated and sprayed metal.
Metal is where most diode lasers hit a wall. To permanently mark bare steel, brass, or aluminum you really want a fiber laser, which uses a wavelength that bare metals absorb. Here are the machines that do metal right.

1. xTool F1 — Best Overall for Metal
xTool F1 (Fiber + Diode)
- Dual fiber + diode source marks bare metal and engraves organics.
- Galvo speeds up to 4,000mm/s for fast small marks.
- Enclosed and portable — ideal for personalization booths.
- Small 115×115mm work area limits larger pieces.
The xTool F1 is the most versatile metal-capable laser for makers. Its fiber source marks bare stainless steel, brass, aluminum, and titanium with deep, permanent results, while the diode source handles wood and leather — so one machine covers metal jewelry, tools, and organic gifts. The galvo mirrors make it astonishingly fast on small marks, and the enclosed, portable body makes it perfect for on-site personalization. The only real limit is the small work area.
2. Monport 30W Fiber — Best for Deep Marking
Monport 30W Fiber Laser
- 30W fiber source for deep etching and even shallow metal engraving.
- Large galvo field with a rugged industrial build.
- EZCAD2 software with fine control over depth and grayscale.
- Bigger, heavier, and pricier — a true shop tool.
When you need to do more than surface-mark — deep serial numbers, logos etched into tool steel, or production volumes — the Monport 30W fiber laser steps up. The extra power cuts marking time and enables real depth, and the industrial build is made for daily use. It’s a bigger commitment in price and space, but for a metal-focused business it’s the right tool.
3. ComMarker B4 — Best Portable Fiber
ComMarker B4 (20W Fiber)
- 20W fiber in a compact, desktop-friendly form.
- Quick to set up and move; great for small-shop metal marking.
- Handles steel, brass, aluminum, and gold/silver.
- Needs a safety enclosure or rated goggles — fiber light is hazardous.
The ComMarker B4 splits the difference between the tiny xTool F1 and a full industrial unit. With 20W of fiber power and a compact footprint, it marks metal quickly and is easy to fit into a small workspace. It’s a favorite for jewelers and knife makers who need solid metal marking without a huge machine. Just take fiber safety seriously — invest in an enclosure or proper goggles.
4. xTool S1 40W — Best Diode for Coated Metal
xTool S1 (40W diode)
- Marks anodized, painted, and coated metal directly.
- Marks bare stainless with Cermark or dry-moly spray.
- Enclosed safety and a large work area for bigger items.
- Cannot deeply etch bare metal like a fiber laser.
If your “metal” work is mostly anodized aluminum, powder-coated tumblers, or stainless that you can treat with marking spray, you may not need a fiber laser at all. The enclosed xTool S1 40W marks coated metals directly and does a clean job on bare stainless with a coat of Cermark. It also engraves wood, acrylic, and leather, making it a flexible all-rounder when metal is only part of your work.
5. Atomstack M4 — Best Budget Metal Marker
Atomstack M4 (Infrared Diode)
- 1064nm infrared diode marks bare metal at a low price.
- Compact and simple — a low-cost entry to metal marking.
- Marks stainless, brass, aluminum, and gold/silver.
- Lower power means slower marking and less depth than true fiber.
The Atomstack M4 uses an infrared diode at the same 1064nm wavelength as fiber lasers, so it can mark bare metal at a fraction of a fiber unit’s cost. It’s slower and shallower than a real fiber laser, but for hobbyists who want to personalize metal items occasionally without spending thousands, it’s a clever, affordable option.
How to choose a laser engraver for metal
- Bare vs coated metal is the key question. Coated, anodized, or sprayed metal can be marked by a diode. Bare steel, brass, and aluminum need a fiber (or infrared-diode) laser.
- Match power to depth. Surface marks and logos need little power; deep etching and production volume call for 20–30W+ of fiber.
- Mind work area. Fiber galvo lasers often have small fields (100–150mm). For larger items, look for an extended lens or a bigger machine.
- Take fiber safety seriously. Fiber laser light is especially hazardous to eyes — use an enclosure or wavelength-rated goggles every time.
The bottom line
The xTool F1 is the best laser engraver for metal in 2026 for most makers — versatile, fast, and capable on bare metal and organics alike. Step up to the Monport 30W for deep, high-volume marking, choose the ComMarker B4 for a compact shop fiber, or use the xTool S1 40W with marking spray if your metal work is mostly coated.
