Slightly off topic but I built my own CNC 3 axis milling machine (X, Y and Z) some years ago which is mostly collecting dust :-) It's pretty high precision, solid, screw/stepper drives. If I want to convert it into a 3d printer what would be my best/cheapest route? I.e. getting a printing head and software setup to drive it all?
You know what? Call me when it can connect wirelessly to my computer, just as my 2D printer does right now.

Throw it in a microwave. That is the way i sanitize my bamboo cutting boards when there are tiny traces of meat inside after tenderizing. If that bacteria have water molecules in them they will be dead. And if they don't - you may be sick but you will get nobel prize in biology anyway.
you can also dip stuff in acetone to smooth it and perhaps enamel it to really seal it up. I imagine there's a bunch of stuff you could do to improve the odds. However, treating a 3d printed spoon like any old metal spoon adds risk.
When it comes to consumer-grade 3D printing, it seems like all the focus on developing a cheap machine and none of the focus is on figuring out something that people actually want to print. So you can print a spoon and a bowl... great. But I actually already have one of those. If I ever have a need to print an endless supply of 1-inch square cubes, I guess 3D printing is just the ticket. I'm not saying they need to b…

FWIW, don't eat from 3d printed stuff. The extrusion process creates this wonderful internal maze for bacteria to thrive in. A single use shot glass is probably ok. And, the ceramic prints you can get now are food grade. But any home made abs or pla will inevitably get you sick, because it can't be cleaned.

Oh man, I've never heard of their printers before. The multi-color $2500 version looks really cool. Now if this Kickstarter project could do that for $400 I would be all over it.
so if you could get a $2500 product for $400 you would buy it?
I stopped watching when I realised this printer is "cloud based" and "connects wirelessly to their servers". You know what? Call me when it can connect wirelessly to my computer, just as my 2D printer does right now.
"We have a backup WiFi printing mode similar to Octoprint..."
Does the market need a cheaper printer, or a better one? I've used 6 types of 3D printers. (Extrusion type, ABS or PLA) 3 from the 'consumer' grade and 3 from the 'pro' grade. Each of the consumer grade printers was an exercise in frustration. All the printers had ugly, clunky software, but the pro printers would almost always make the thing I wanted. The consumer printers I've tried take 3 or 4 failures to get 'set…
Though, $250 was just too good to be true, so I went against instinct and bought one anyway. :D

why can't you wash the items with soap?
