They are circumventing China manufacturing issues by not manufacturing in China (or doing assembly in the us at least). Looks like they've solved their biggest technical hurdles (power supply issues). I think anyone can look at the posts on their community forum if you want. No idea how the software is going along. http://community.glowforge.com/t/glowforge-update-betas-maker-faire-production/2823 moron izzard fucked around with this message at 20:42 on Sep 10, 2016 |

so i learned about this recently http://wazer.com/ gonna be on kickstarter on 9/12  ++;i like: the idea of a cnc waterjet that doesn't cost $250,000 i don't like: the idea of a cnc waterjet using a 50,000 psi turbopump built by the cheapest chinese contract manufacturer

Honestly about a decade ago I went to the electronics store, picked up a small plastic enclosure and several switches that had nice feels to them and just made a lil box with all these nice fiddly bits. If you told me that was a multi million dollar idea I would have laughed at you.  edit: lmao $2.8 mil. https://ksr-video.imgix.net/projects/2589968/video-700472-h264_high.mp4 I didnt actually watch the video before but lmao at 2minutes on.

poo poo 2.8mil and the campaign has barely started; goal at 15k. Unless it was all a masterminded thing they have a shitload of problems to solve that they never thought they would have to solve to fulfill 2.8mil of orders versus even just a hundred thou $ worth.

I sure hope they worked out their costing really well and have included a healthy profit in that price. imagine getting $2.8 million worth of orders and it's all break-even

A guy I know did a reasonably successful kickstarter for a plastic widget and in the end it broke pretty even, fulfillment was what ate up the margin. Could be worse, could find out you could have just handed out 5$ bills for an afternoon and ended up the same financially. Our would have ended with MORE money in the end had you just played xbox instead of making and selling a thingie.

the usual figure thrown around is that you need to sell for ~2.5x your BOM cost to break even once you factor in all the manufacturing costs. and i dont think that accounts for shipping costs to customers

The WAZER actually seems reasonable. A professional machine at 60k psi will do 1" thick 2024 Aluminum at about 19ipm, the wazer will do 1/16" at 2.8ipm. With the massive cost difference, they're probably using a substantially lower power pump, but even for the list of materials that don't really get that thick, the speeds it cuts are believably low enough for a home unit and for some thing, much easier than by hand and possibly more convenient than a laser cutter. Looks like the money is going to manufacturing costs for bulk parts ordering and development of waterjet-specific software, and they seem to have working prototypes and most development done. Some cost cutting measures done and no divulging of the water pressure, but it actually seems doable to the extent they are almost completely sold out of the very limited machines. Not even the thing of more questionable projects where they have a virtually unlimited number of machines at some price points, they actually seem fairly legitimate.

there was a waterjet guy posting on hack-a-day who ran the numbers and figures they're using a 5000psi pressure-washer pump. the abrasive usage is linear with time and water flow, not pressure, so cutting that steel sprocket they use as an example (takes about 55 minutes they said) would use something like 30 pounds of garnet sand, and that's not reusable. essentially it's trading out the 60,000 psi intensifier pump for slow erosion and vastly increased abrasive usage. there are also a bunch of unrealistic or mistaken values in their specs for tolerance and maintenance life too apparently.

Thanks, I missed that post. That pump would make sense why it runs on average home power and has fairly poor cutting performance, it's basically being a wet grinder with horrible abrasive consumption and completely flow through water as opposed to filtering. I figured some of their values had to be optimistic given some of their cost cutting measures and having to build it to a price, but at that cost it probably would be easier to either sacrifice an old pressure washer or just snag a laser cutter, since having to vent it seems like a good tradeoff for a machine that won't suck down consumables at an insane rate and doesn't function as a fancy wet grinder.

Theres a lot of materials you can't cut in a laser cutter tbh, and especially not in an entry level one. I'm gonna have to get one of those cheapo cncs so I can cut the smaller carbon fiber and g10 stuff I wanna do soon.

Yeah I didnt see how much it used up in consumables, jesus. And most shots just show the top unit, not picturing the huge pump unit at the bottom.

Nah, it wouldn't take up anywhere near that much space. Think logically: garnet is a mineral, so it weighs more than water. One metric ton of water occupies 1 cubic meter -- a little bigger than a dishwasher. I'm guessing 1000kg of garnet would be about the size of a 55-gallon drum. It wouldn't take up your whole house, but you'd need a forklift to deliver it.

Like, I mean if you got some laser cutting to do it's probably worth it to buy a Chinese one cause you can do a lot of lasering between now and end of 2017 at earliest. Like, just dump it on kijiji or at a hakkerspace or just never touch it again when the glowforge arrives and solves all your problems letting you cut happily in the middle of the kitchen. e: I mean, I just can't fathom the idea of feeling like "I am certain I will need this particular machine in 16 months, so certain of it in fact that I will pay for it right now."

I've thought about it and it's really not up to me to tell what or where someone else places value. I mean, poo poo I'd roll my eyes at someone suggesting I buy a decent handheld router and practice a little now instead of waiting for some smart CNC thing. I guess I just thought they were much further along the 'figuring out how to build our product' road.
