Fuck, I hate not living in the US when things like this appear.

Worst part is that if I try to buy something like this in Brazil, it'll probably get apprehended by customs as a dangerous item.

If there are no importers/dealers in Brazil, this is a business opportunity to import machines from China.

I have a 40W hobbyist laser cutter. It's fun, and a great tool for various projects, like making board games[1,2]. That said, sometimes materials inside the machine catch fire, and sometimes the beam reflects or dwells on a section of the metal enclosure. It's interesting that they've chosen to make the entire (?) enclosure out of plastic, itself a combustible material. I get why they went with plastic (cheaper to fabricate once you have the molds, lighter to ship, perhaps better dimensional accuracy than cheap sheet metal), but it does not seem particularly safe. The also seem to gloss over the need to ventilate the machine. Plastic fumes are nasty to breathe, glue-bonded wood (think thin plywood) can release formaldehyde fumes, leather may be dyed with heavy metals. What the laser doesn't cause to combust cleanly, it vaporizes. You don't want those emissions in your house of office, and you want them vented away from the optical components as quickly as possible so there is no deposition onto mirror or lens surfaces.

Another benefit of metal enclosures is shielding the power supplies of these things. High-voltage laser power supplies are noisy, and when you PWM them, they can cause quite a bit of interference. Metal enclosures at least help to attenuate RF emissions.

The "macro camera" is a clever addition for closed-loop optical control (if it is being used for that). Reminds me of attaching an optical mouse sensor the the lens sled.

One of their sample images appears to be of the "Below the Boat" series. http://www.belowtheboat.com/ I've given those maps as gifts, and they're very nice quality. Is there any relationship between your companies? Are they using your laser cutter?

(ceo/cofounder here) There are lots of folks doing bathymetric maps with lasers; I don't know who was first to it. We generated ours from scratch from NOAA data, but owe them (or whoever did it first) a debt of inspiration.

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…

(cofounder/ceo here) I don't remember which sample items we made on which model, but everything you see is printable on the basic model. For example, the monitor stand and dollhouse don't have pieces larger than 12x20.

Pretty sure they are talking about the K40 "blue box" laser. I have heard they require some mods to get working properly but for the price some think they are worth it.

More info please :)

These things.

A 100 unit break even point is incredible low. Have you read many of the write ups on product based Kickstarter campaigns. From what I have read most break even point are into the 1,000 plus units if you have to account for fabricating molds or dies. Then these mold and dies can only be used fro one project. That is the beauty of 3D printing, laser etc. You have one tool that can be used to fab hundreds of designs or product with no tooling costs.

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

(ceo/cofounder here) You're right - it's the passthrough. CDRH is very strict about what could count as human access. We have some clever interlocks in place around the passthrough but if an examiner can place a mirror in the interior and measure laser output above the threshold without triggering the interlock, you're Class IV.

It's Brazil...

This would be a nightmare to make happen, you would need to bribe so many people to get a shipment here that your profit would be unworthy and also make you a criminal or you can run it by the lawn and never get the items or pay 100% taxes over them + their shipping costs making a machine like this cost U$5000,00
