Let me get this out of the way: I don't think the Glowforge Aura, or any desktop laser engraver in its class, should be able to cut metal. And I'm tired of pretending that's a flaw.
I've been using the Aura for about eight months now, mostly for small-batch custom work—wedding favors, slate coasters, leather keychains. When people ask me about it, the first question is almost always about wattage. 'What's the Glowforge Aura wattage?' 'Can it cut 1/4-inch acrylic?' 'Does it engrave on stainless steel?'
These are the wrong questions. Here's why.
Most buyers focus on wattage and completely miss workflow
The Aura is a 40W CO2 laser tube. Actually, I should correct myself there: it's a 40W tube, but the effective optical power is lower. The output at the lens is probably closer to 30-35W, depending on how clean your optics are and what temperature your shop is. That's a fact of physics, not a failing of the machine.
But here's the thing—I've used industrial CO2 lasers rated at 80W and 100W. They can cut thicker materials, sure. But they also cost three to four times as much, take up the space of a small car, and require a chiller and ventilation that would be overkill for my garage. The Aura fits on my workbench. It plugs into a standard wall outlet. I can move it to a different location in about twenty minutes if I need to.
The real question isn't 'how powerful is the tube?' It's 'can you get the job done within the machine's limits?' For 90% of the work I do—engraving on slate, cutting 1/8-inch birch ply, marking anodized aluminum—the Aura is more than enough. The other 10%? I outsource it to a local shop with a fiber laser or a larger CO2 system. That's not a weakness; that's knowing the boundaries of your tools.
The question everyone asks is 'what's the maximum wattage?' The question they should ask is 'how easy is it to get from design to finished product without a degree in laser physics?'
How I learned this the hard way
In February 2024, a client called me at 4 PM needing 36 engraved slate coasters for a corporate event the next morning. Normal turnaround for that kind of job is three to four days—you have to source the slates, test the settings, run the batch, and handle the cleanup. But he'd messed up the order with his usual supplier and needed a miracle.
I had about six hours to decide: do I take the order and run the Aura all night, or do I say no and lose the $1,200 job?
I took it. And honestly? I should have said no. The slate coasters themselves were fine—the Aura handles slate beautifully at about 80% power and 400mm/s. But the rush created downstream problems. I didn't test the laser settings on the specific batch of slates he sent over, and about six of them had tiny surface imperfections that caused uneven engraving. I ended up redoing those six at 1 AM, paying an extra $50 in overnight shipping to get them to a different address because I missed the original courier cutoff.
I delivered the order on time. My margin on that job was basically zero after the rush fees and shipping. The client was happy, but I learned something: saying 'yes' to everything doesn't make you a better craftsperson. It makes you a worse business owner.
That's what I mean when I say the 'can it cut everything?' mindset is the wrong one. The Glowforge Aura cannot cut thick stainless steel. It cannot cut 3/4-inch hardwood. It will not replace an industrial laser cutting machine or a CNC router. But if you walk into a purchase thinking your desktop laser should do everything, you're setting yourself up for disappointment. More importantly, you're ignoring the one question that actually matters for small business owners: can you consistently deliver good work within the machine's real capabilities?
I'd rather work with a specialist than a generalist
This extends beyond the laser itself. I've had the same conversation about printers, about materials suppliers, about finishing services. The vendor who said 'this isn't our strength—here's who does it better' earned my trust for everything else. The one who promised 'anything you need, we handle it' usually delivered mediocre work across the board.
The Glowforge Aura is a specialist. It's designed for crafters and small business owners who need a reliable, easy-to-use desktop laser that does specific things really well. It engraves on slate, leather, wood, and anodized aluminum with consistent quality. It cuts acrylic, thin wood, paper, and fabric up to about 1/4-inch. It integrates with software that actually works, unlike some machines I've used where you need a library of forum posts to make basic adjustments.
That's its lane. And staying in that lane is a feature, not a bug.
What about making money?
People always ask: can you make money with a laser engraver like the Glowforge Aura?. My answer is yes, but only if you're honest about what it can and can't do.
Based on my numbers over the past eight months: I've processed about 120 orders, ranging from $25 keychains to a $600 bulk slate order. The Aura itself ran for about 340 hours total. I track every hour because I'm paranoid about tube life (the Aura uses a CO2 tube that typically lasts 1,500-2,000 hours, and replacement is around $300-400).
I've had failed jobs. About 5% of my orders had some kind of issue—misaligned engraving, material defects I didn't catch, settings I dialed in wrong. On a few of those, the Aura's software saved me: the preview mode, though sometimes laggy, catches alignment mistakes before you fire the laser. That feature alone has saved me more in wasted materials than the cost of the machine.
On the cost side: materials and consumables run about 15-20% of my selling price. Shipping eats another 10-12%. Rush fees on materials from suppliers add maybe 2-3%. My net margin is around 55-60% on standard orders, less on rush jobs. That's healthy enough, but only because I've learned to say no to work that doesn't fit the machine's capabilities.
The objection I hear most often
'But what if I need to cut thicker acrylic?' 'What if a customer wants a metal engraving?' 'Isn't it limiting to have a machine that can't grow with you?'
Here's my honest answer: if you're regularly cutting 3/8-inch acrylic or engraving on hardened steel, the Glowforge Aura is not your tool. There are excellent mid-range CO2 machines (around $3,000-6,000) that handle those materials, and there are fiber lasers for metal marking. If your business model depends on those capabilities, buy the right tool for the job.
For me, the day I tell a client 'actually, this slate coaster project is better done on a different kind of laser' is a good day. It's a good day because I'm not overpromising. I'm not taking a job I can't execute well. And I'm building a reputation for honesty that leads to repeat business and referrals.
That's worth more than any spec sheet claim about 'all-in-one' capability.
So what does this all mean?
The best tool for your business is the one that matches your actual needs, not an imaginary ideal of 'maximum capability.' The Glowforge Aura is a capable, accessible desktop laser that excels at a specific range of materials and applications. It's not an industrial production line. It's not a metal cutter. It's not your only option for every job.
But if you can accept those boundaries, work within them, and build a business model around them? You'll produce better work, build stronger client relationships, and sleep better at night knowing you delivered what you promised.
I've learned more from the jobs I turned down than from the ones I accepted. And I'd rather have a machine that does fifteen things well than one that promises to do fifty things poorly.
That's just my take. Based on real work, real orders, and real spreadsheets. Your mileage may vary—but hopefully, this helps you ask better questions before you buy.
