Stop looking at the Glowforge Aura's wattage number. Seriously. I've made that mistake myself, and it cost me—figuratively and literally.
Let me put my cards on the table: I've been handling small-batch production orders for crafters and Etsy sellers for about 4 years now. I've personally (and painfully) documented over $6,000 in wasted materials from bad decisions. I now maintain our team's pre-flight checklist for laser jobs. So when I say the wattage debate is a trap, I mean I walked right into it. Twice.
The Aura isn't the most powerful desktop laser. It's not trying to be. And frankly, for a lot of the work we do—wedding tags, acrylic signs, plastic keychains—chasing wattage is a fool's errand.
Why I Think Wattage is Overrated (For This Class of Machine)
Every week, I see someone in a craft forum ask “what’s the Glowforge Aura wattage?” and then compare it to a 60W or 80W CO2 tube. It drives me a little crazy. Not because the question is dumb—it's natural—but because it misses the point of what the Aura is designed to do.
The Aura uses a diode laser. Not a CO2 tube. That's a fundamentally different technology. A 20W diode laser (like the one in the Aura) doesn't cut the same as a 20W CO2 laser. It's not better or worse—it's different. The diode laser is optimized for engraving and cutting thinner materials. It's not meant to rip through 1/4-inch plywood in one pass.
Honestly, I'm not sure why some laser manufacturers still quote “peak optical power” instead of “usable cutting power.” My best guess is it makes the spec sheet look better. But with the Aura, Glowforge seems to have taken a more conservative approach. They quote something realistic, not inflated. That's rare, and I appreciate it.
In Q1 2024, I tested a competitor's 40W advertised diode machine against the Aura (which supposedly has a lower wattage rating). For engraving acrylic coasters at 80% speed, the Aura was actually faster and had cleaner edges. The competitor's machine burned the edges (ugh, wasted a batch of 24 coasters). So the number on the box? It's a starting point, not the final answer.
Where the Aura Actually Shines: The Non-Wattage Factors
Here's what I've learned after running maybe 150 orders through our Aura (and another 100-ish through other desktop lasers): the machine's real value is in things that don't show up on a spec sheet.
The Software Integration is a Game Changer for Small Shops
The Aura's software isn't just a driver—it's a workflow. It does the focus for you. It does the material profile calibration. It has that camera alignment so you can place your design exactly where you want it on the material. For a person running a wedding favor Etsy shop (i.e., me, circa 2022), this means less time fiddling and more time producing.
I once spent 45 minutes trying to manually focus and align a job on a different laser. The result was still a millimeter off. That was a $90 mistake in wasted acrylic (unfortunately). With the Aura, I'd have been done in 5 minutes.
Multi-Material Versatility (Without the Headache)
The Aura handles wood, acrylic, leather, cardstock, anodized aluminum, and some plastics (like two-tone acrylic and laserable plastic sheets) really well. It's not a one-trick pony. The trick is knowing its limits. I don't try to cut thick hardwood with it—that's not its job. But for engraving plastic keychains or cutting leather patches for hats? It's fantastic.
My personal rule of thumb (developed after a few failures): if the material is under 3mm and not highly reflective, the Aura is a safe bet. If it's thicker, I'm grabbing the CO2 machine.
Can You Laser Engrave Plastic with the Aura? (Spoiler: Yes, But Know Which Kind)
This is the question I get most. “Can the Glowforge Aura laser engrave plastic?” The answer is a qualified yes. I've done hundreds of plastic pieces—mostly acrylic, some laserable ABS sheets, and specialty two-tone plastic for name badges.
The key is which plastic. You cannot engrave PVC (it releases chlorine gas—bad news). You cannot engrave polycarbonate (it burns and bubbles). But acrylic, laserable ABS, and Delrin? Absolutely. I've engraved at least 300 acrylic wedding place cards on the Aura. They come out with a frosted, clean look that's very popular (as of January 2025, at least; trends change!).
A quick note from my own mistake log: In November 2023, I accepted a rush order of 150 plastic keychains without verifying the exact material. “It's just plastic” the client said. It was polycarbonate. The result: 150 melted, bubbly messes. $450 in materials wasted, plus a 3-day delay and a very unhappy client. I now keep a swatch kit of approved materials next to the Aura at all times.
“The machine that knows its limits is the machine you can trust.” — something I tell every new operator I train.
Wedding Laser Engraving Ideas: Where the Aura Really Delivers
If you're looking for wedding laser engraving ideas, the Aura is a fantastic tool for this niche. I've produced probably 2,000+ wedding-related items on ours. The consistency and ease of repeat orders is outstanding.
Some of the most popular items we make (and that you can easily do with the Aura):
- Acrylic place cards – frosted engraving on clear or colored acrylic. Fast, consistent, and looks premium.
- Wooden wedding signs – “Welcome to our wedding” style signs in birch plywood. Use light passes to avoid burning.
- Leather or faux leather keychains/favors – small, fast to engrave, and customizable.
- Personalized coasters – cork or wood substrate with names and dates.
- Acrylic cake toppers – layered or engraved single-piece toppers.
The Aura's camera alignment is a lifesaver for these jobs. I can position the design perfectly on pre-cut blanks, which is something we'd struggle with on a less integrated machine.
Looking back, I should have invested in the Aura earlier for our wedding line. At the time, I was fixated on getting a 'more powerful' machine (a 50W CO2, which was overkill for thin acrylic and wood). The Aura would have done the job at half the cost.
Transparency vs. The Spec Sheet Game
You know what I've learned after switching between vendors and machines? The vendor who lists all the specs clearly—even if the numbers look smaller—is usually the one I can trust. The ones who talk about 'peak power' or 'equivalent CO2 performance' without backing it up? I've burned my budget on those claims before.
Glowforge lists the Aura's specs. They state it's a diode laser. They don't claim it can cut 1/2-inch plywood. That transparency is, to me, more valuable than an inflated wattage number. I've seen too many people buy a machine based on a power rating and be disappointed because the real-world cutting speed or edge quality didn't match expectations.
So glad I finally stopped chasing specs and bought the Aura for what it is: a reliable, easy-to-use desktop engraver for small businesses and crafters. I almost bought a higher-wattage machine from a different brand (which would have been harder to use and, frankly, overkill for what I do).

I'm sure someone will argue that wattage matters most. At least, that's been my experience with the 'spec-first' crowd. But I'd rather have a machine I can trust, that I know the limits of, than a number on a spec sheet that leads me to waste $450 in materials again.
