This is arguably the most important decision. The type of laser you choose dictates what materials you can cut, engrave, and mark. Don't buy a laser until you know what you want to make with it.
- Diode: This is the most common and affordable type for hobbyists. It's fantastic for Wood, Leather, Fabric, dark Acrylic (it can't engrave clear or blue), and marking painted Metal or Stainless Steel (with a special spray).
- CO2: The versatile workhorse. CO2 lasers excel at cutting Wood and Acrylic (all colors, including clear) very quickly. They are also the top choice for engraving Glass and Stone.
- Fiber / MOPA Fiber: This is the specialist for Metal. If your primary goal is engraving Stainless Steel, Jewelry, or hard Plastic, a fiber laser is what you need. MOPA is a type of fiber laser that can even engrave in color on some metals.
- Infrared: This is a newer technology, often found as a module for diode lasers (like from xTool). It bridges the gap, allowing a diode machine to effectively engrave all metals (including precious metals for Jewelry) and plastics, similar to a fiber laser but at a lower power.
Your project goals come first. If you want to cut clear acrylic or engrave drinking glasses, you need a CO2 laser. If you want to engrave metal tools or jewelry, you need a Fiber or Infrared laser. For everything else (wood, leather, etc.), a Diode laser is the perfect, cost-effective choice.
Power, measured in watts (W), determines how fast and how deep your laser can work. More power isn't just for "stronger" engraving; it's about speed. A 20W laser can cut through a piece of wood in a single pass, while a 5W laser might need four or five passes, taking much longer.
- Diode Laser (5W - 40W+):
- Entry Level (Up to 5W): Good for basic engraving and marking. Cutting is very slow and limited to thin materials.
- Standard Hobbyist (6W - 15W): The sweet spot for many. Great at engraving and can comfortably cut 3mm-6mm wood and acrylic.
- Power User (16W - 30W): For serious hobbyists. These machines are much faster at engraving and can cut thicker materials (8mm-12mm) with ease.
- Cutting-Focused (Over 30W): These top-tier diodes rival low-power CO2 lasers in cutting speed and capability.
- CO2 Laser (40W - 100W+):
- Desktop / Hobbyist (Up to 40W): This is the standard for desktop machines like a Glowforge or Monport. It's extremely capable for cutting and engraving a huge range of materials.
- Prosumer / Production-Grade (41W – 100W+): These are larger, faster machines intended for small businesses or serious production.
- Fiber & MOPA Laser (20W - 100W+):
- Surface Marking (Up to 30W): Perfect for logos, serial numbers, and QR codes on metal. MOPA lasers in this range can do color marking.
- Deep Engraving (51W+): Needed for physically removing metal, such as for firearm engraving or making injection molds.
- Infrared Laser (1W - 5W+):
- Standard (1.1W – 2W): This is the typical power for an add-on module. It's more than enough to mark all metals and plastics effectively.
For most beginners, a 10W or 20W diode laser offers the best blend of price and performance. If you are serious about cutting, look at 30W+ diode or a 40W CO2 laser.
This is your "canvas size." The working length and width simply define the maximum dimensions of a project you can fit inside the machine. Think about what you want to make. Are you engraving cutting boards or tiny keychains?
- Small (Under 150mm): This is territory for portable lasers (like a LaserPecker) or compact fiber lasers. They are great for small items like tumblers, phone cases, or jewelry.
- Medium (150mm - 299mm): Often found on enclosed CO2 lasers (like a Glowforge Basic) or compact desktop units.
- Large (300mm - 399mm): A very common size for desktop diode lasers. A 300x400mm area is a great starting point for signs, boxes, and small panels.
- Extra Large (400mm & Over): This is the standard for most open-frame "gantry" style diode lasers (like from xTool or Sculpfun). A 400x400mm or 400x600mm area is extremely versatile, and many models are expandable with extension kits.
It's tempting to get the biggest area possible, but measure your own workspace first. For most hobbyists, a Large or Extra Large area (e.g., 400mm x 400mm) is the most flexible choice and won't feel limiting.
Speed, measured in millimeters per second (mm/s), refers to how fast the laser head can travel while engraving. Faster speeds are a huge quality-of-life improvement, as "filling" a large engraved area can take hours on a slow machine.
- Standard (Under 500 mm/s): This is typical for older or entry-level budget machines. It works perfectly well, but large, complex jobs will test your patience.
- Fast (500 - 1000 mm/s): A modern standard for many diode and CO2 lasers. This speed feels responsive and completes jobs in a reasonable amount of time.
- High-Speed (Over 1000 mm/s): This is common in high-end diodes (like xTool S1), CO2, and fiber lasers. While you may not always engrave this fast (the material needs time to burn), a high top speed means the machine's motors and frame are built for rapid, precise movements, which reduces overall job time.
Speed is a "nice-to-have" feature, but a very nice one. If you plan on running a small business or doing large "fill" engravings (like a photo), look for machines in the Fast or High-Speed categories.
This is where machines really start to differ. These features separate a frustrating tool from a creative partner. Prioritize safety features first, then look for convenience.
- Enclosed Design: A case that surrounds the laser. This is a massive safety feature. It contains fumes (when vented), blocks the powerful laser light, and often dampens noise. It's a standard on all CO2 and fiber lasers.
- Built-in Air Assist: A pump that blows air directly at the laser point. This is essential for clean cuts. It blows away smoke, prevents flare-ups, and stops the wood from getting "sooty," while also protecting the laser's lens.
- Rotary Included: A separate attachment (a "rotisserie") that lets you engrave on round objects like tumblers, cups, and even rings. If this is a major goal, getting it bundled is a good deal.
- Auto-Focus: The machine automatically detects the material thickness and sets the correct laser focus (height). This is a huge time-saver and removes guesswork.
- Built-in Camera: A game-changer for usability. The software shows you a live picture of your material on the laser bed. You can just drag your design and place it exactly where you want it.
- Touchscreen / Offline Control: A small screen on the machine that lets you select files from a TF card and run jobs without having your computer tethered to the laser.
- Portable: Small, lightweight, and sometimes battery-powered. Designed for taking to craft fairs or working on items that can't fit in a normal laser.
- Flame Sensor / Tilt Stop / Emergency Stop: These are critical safety features. The machine stops if it detects a fire, if it gets bumped or tipped over, or if you slam the big red "Stop" button. Do not compromise on these.
- 3D Engraving: A software feature that varies the laser power based on a grayscale image to create a carved, 3D-relief effect in wood.
- Color Engraving: A niche feature, typically for MOPA Fiber lasers creating colors on stainless steel or titanium.
At a minimum, look for a machine with good safety (Flame Sensor, Enclosed Design or proper eye protection) and Air Assist. For the best user experience, Auto-Focus and a Built-in Camera are worth their weight in gold.
How do you get your designs to the machine and tell it what to do? That's your workflow. Good connectivity and powerful software are just as important as the laser itself.
- Connectivity Options:
- USB: The standard, reliable, wired connection to your Mac or PC.
- Wi-Fi / App Control: Highly convenient. Send jobs wirelessly from your computer or even a tablet.
- TF Card (Offline): Load your file (the "g-code") onto a memory card, plug it into the laser, and run the job. This is great for freeing up your computer.
- Software Compatibility:
- LightBurn: The most popular and powerful third-party software for hobbyist lasers. It works with almost all non-proprietary machines, is extremely capable, and is worth the (small) extra cost.
- LaserGRBL: A free, open-source, and powerful option for many diode lasers. It's a bit more technical than other options but very effective.
- xTool Creative Space / AlgoOS / Falcon Design Space: These are brand-specific, proprietary programs. They are often very easy to use, especially for beginners, and are tightly integrated with their machine's features (like the camera). The downside is you are locked into their ecosystem.
The best setup is a machine that offers Wi-Fi and TF Card options but also has a USB port as a backup. Ideally, choose a machine that is compatible with LightBurn, as it gives you the most power and flexibility for the future, even if you start with the brand's free software.
The brand name isn't just a sticker; it's your pipeline for customer support, accessories, and community help. While there are dozens of brands, a few major players lead the pack in quality and support.
- xTool: A dominant force in the hobbyist market. They make high-quality diode (D1, S1) and CO2 (P2) lasers with a very polished, user-friendly software (Creative Space) and lots of accessories.
- Glowforge: Famous for making the "3D laser printer" mainstream. Their enclosed CO2 lasers (Aura, Plus, Pro) are incredibly easy to use, relying on a cloud-based app and camera system.
- OMTech / Monport: These brands are the go-to for more powerful, "prosumer" CO2 lasers. They offer fantastic power for the price but often require more technical setup and tinkering.
- Sculpfun / Atomstack / Ortur: These are popular and reputable brands for open-frame, budget-friendly diode lasers. They are great "tinkerer" machines and are almost universally compatible with LightBurn.
- LaserPecker: The leader in the portable laser category. If you want a small, handheld, or compact engraver for small items, this is the brand to look at.
You can't go wrong by starting your search with xTool for an all-arounder, Glowforge for plug-and-play ease (CO2), or OMTech/Monport if you're ready for a more powerful CO2 machine. For budget-friendly diode options, Sculpfun and Atomstack are excellent starting points.
