In the video, at about 13:40 they reveal that to print you have to use the web interface which runs "On Googles Cloud".

I would not like the interface to my own printer to be "In the Google cloud". Does that mean when the company goes out of business, the printer is bricked?

And right after, they admit that they plan adding paid services. Oh oh. How will thesed paid services be announced? I can imagine how. Whenever I want to print, this thing will bug me to pay for some fancy addon.

And privacy? Goes right out of the window. Everything I print would go through all kinds of hands. The manufacturer of this printer, Google, my carrier and who knows who.

And what about security? This is probably a full blown computer they want me to give access to my lan and internet connection. Who guarantees it gets security updates?

It's a very polished product, and the "pen" mode is a cool idea. To me, they're targeting an odd demographic, Makers who can afford expensive toys / tools, but also want a very friendly, hands-off interface. I would have expected the Maker camp to be ordering ~ $700 40-50W laser cutters from Shenzhen. I suppose the Glowforge would be pretty great in a school setting, though.

Good question, I _think_ the ideas is the exact opposite -- you're not depending on Glowforge UI to be backed by a startups servers, the software runs on google cloud instead. Pros and cons, obviously, but I think the main pro is (like a Tesla) the machine's performance and usability can be improved without you installing any new software. As far as dependencies go, google's probably the best possible choice.

I am surprised it can cut paper without causing ignition.

I wonder how many of the projects shown were created using the "basic" ($2K) version and how many were produced using the pro ($4K) version?

I will say their early bird prices make these compelling for small business/etsy setups. However once they go to full price, I don't know if that will remain as true. It would take a LOT of wallets to break even at a $4K buy-in for the "basic" version.

PS - We live in an exciting world. Between 3D printers and these, you really can do more at home than ever before. And this type of technology is bringing tooling prices down massively even if you have it fabricated.

PPS - Looking at the material costs on their page, and looking at how much these items sell for on etsy right now ($39 inc. free postage), you'd have to sell over one hundred hardback skins for a Macbook Pro just to break even (and that's ignoring many of the hidden costs of running a business, like accountant, licensing, your salary, etc).

How is a 40W laser Class I, but the 45W laser is Class IV?

This one I actually know -- biohazards depend on more than just wattage -- spot size, wavelength, pulse characteristics, etc, all go into it. I think you really compare them based on the Poynting vector.
