Glowforge Aura Wattage Review: The 20W Craft Laser Cutting Machine After 3 Months

After three months with a Glowforge Aura in our 14-person product-design office, here's the short answer: the Glowforge Aura is a 20W CO2 craft laser cutting machine, not an industrial cutting table. It won't cut thick metal. But for a small UK business doing prototypes, client gifts, glass etching, and light wood or acrylic cutting, it's been worth every pound.

I say that as a buyer, not a laser engineer. For the last six years I've managed office purchasing for a 14-person company in Birmingham, handling about £48,000 a year across 20 vendors. I process 60-80 orders a year and report to both operations and finance. When I took over purchasing in 2020, I learned to read spec sheets with a lot of suspicion. So when we looked at laser cutters, I ignored the hype and focused on what a machine would do on a normal Tuesday afternoon. The Aura has now been that machine for three months.

What is the Glowforge Aura wattage?

Let's get this out of the way. The Aura is listed as a 20W CO2 laser on Glowforge's product page (accessed 12 Jan 2025). Not 20W from the wall, but 20W laser output from the tube. That's enough for a surprising amount of desktop work. It is also a CO2 laser, not a diode laser, which is a way more useful type for cutting wood and acrylic at this power level.

Why does that matter? Because wattage alone doesn't tell you how a laser behaves. A 20W CO2 laser is absorbed well by wood, acrylic, paper, and leather. A 20W diode laser is not the same thing, even with the same number. If your search history includes 'laser cut acrylic,' the type of laser matters as much as the wattage.

What the Aura can't do is cut thick metal. It can mark some coated metals and anodized aluminium, but it won't cut steel or aluminium sheet. I mention this because it's the biggest misunderstanding in laser cutter reviews.

What the Glowforge Aura craft laser cutting machine does well

In day-to-day use, the wattage number translates into a simple list of jobs. We use the Aura for:

• Thin plywood and basswood blanks for packaging samples and small display stands.
• Engraving on glass, anodized aluminium, and leather client gifts.
• One-off acrylic signs and internal labels.

That's not a heavy material list. We're not cutting thick hardwood or production quantities. The Aura handles these jobs with no manual focus because it has a built-in camera and auto-focus. You place the material on the bed, choose a material profile, and press print. What I mean is that this is the closest thing to a 'laser printer' I've seen in a small machine. The software is cloud-based, which made me nervous at first, but after three months it's been more reliable than our office printer.

Before committing, I ran the same total-cost check I use for any vendor. In our 2024 vendor consolidation project, we cut eight suppliers down to three, and the lesson was that the cheapest quote is rarely the cheapest outcome. For the Aura, the total cost included the machine, test materials, a dedicated electrical socket, and staff time to learn the system. The biggest hidden cost was testing: you burn through plywood and acrylic while learning settings. That's not unusual, but budget for it.

Did I hesitate before buying? Yes. The upside was obvious: no more waiting two weeks for a vendor to quote an £80 sample. The risk was a few thousand pounds of dormant hardware. I kept asking myself whether the convenience was worth the risk of buying an underpowered machine. What changed the decision was simple: we had three booked jobs before the order arrived—glass awards, plywood sample boxes, and leather keychains. A machine with waiting work isn't a toy.

Laser etch glass: the easy win

One of the best reasons to buy the Aura is glass etching. It's genuinely simple. We bought a box of cheap pint glasses from a local supplier, set the Aura to a low-power, high-speed engraving setting, and ran a logo on the side. The result is a frosted mark that looks professional.

The catch is heat. Glass can crack if you push the laser too hard. Our first test cracked (surprise, surprise), so we turned the power down and tried again. That's where the built-in camera helps: you see exactly where the design will sit before you fire, so mistakes cost you a cheap glass, not an expensive mug.

Free laser cut patterns are a real time-saver

Another hidden value is the file library. There are a ton of free laser cut patterns in Glowforge's design catalogue and community—boxes, tags, stands, decorations, and templates. You don't need to be a vector designer to get value from this machine. We downloaded a few patterns for sample boxes and display stands and saved hours of work.

The caveat: not every free pattern is tuned for the Aura's 20W. Some were created for the larger Glowforge models with more power. Inspect the cut lines, check material thickness, and run a test cut in cheap material before committing a full batch.

Die cutting machine UK: should you compare them?

If you found this article by searching 'die cutting machine UK,' stop and check whether you're looking at the same job. A die cutting machine uses blades for paper, cardstock, vinyl, and fabric—it kiss-cuts stickers and creases card. The Glowforge Aura is a laser cutter and engraver. It can cut paper and card, but it's better at wood, acrylic, leather, and glass. It is not a vinyl cutter, and you shouldn't use it for PVC-based vinyl because the fumes can harm the machine. If your main product is vinyl stickers, buy a die cutter. The Aura is a different animal.

Support and small-business friendliness

Here's the part that often gets left out of wattage arguments: who treats you like a customer. I've been a purchasing admin long enough to get ignored by vendors who only want volume. Glowforge treated our one-machine purchase like a real purchase. Their UK support answered questions directly. When a part did not fit, they sent a replacement without a fuss. Take it from someone who has dealt with vendors that make you beg for basic service: that counts.

Cloud software: the honest caveat

I won't pretend the cloud-only software is perfect. If Glowforge's servers are down, the Aura won't operate, and that could seriously hurt a workshop that depends on it. We had one short outage in December, about 20 minutes. For our workflow, that's acceptable. If you're running a production line and need reliable offline operation, this is not the machine for you.

Who should not buy this

This worked for us because we're a small office with varied short-run projects and one person who enjoys operating the machine. If no one in your team will take ownership, don't buy it. A laser cutter is not a printer; someone still needs to clean the lens, change material, and test settings. And if your work requires cutting thick metal or running eight-hour production shifts, the Aura is the wrong tool. A 20W laser is a craft laser. That's not a criticism; it's a definition.

Final verdict

So is the Glowforge Aura worth it? For us, yes. The 20W CO2 laser is enough for engraving, glass etching, and light cutting—the jobs that actually pay for themselves. It isn't enough for heavy production, and it will never cut thick metal. The wattage number is honest; the mistake would be expecting it to be something bigger. If your work fits the Aura's size and power, it's a genuinely useful tool. If not, no amount of software will fix that.
