My current night class teacher says he has a rapid prototype machine (maybe more than one, it wasn't clear) where he can make flexible or rigid products within a few hours after designing them in a cad program (out of a corn starch base that can be sprayed with a flexible or rigid coating, or made out of ABS plastic). Anyways, evidently the machines are getting more affordable (currently in the $25,000 range for the type he has), and it sounds really interesting. I want to see this thing work. He also worked for Honda doing 3d design for some motorcycles and ATVs.



Anyone have any interest in this? *cough*banzai*cough*

Mmmmm. Would the cornstarch prototype be edible?

They're pretty cool, you can made one piece parts with moving parts inside.

We used it at a place I used to work for, at the time very expensive

He explained it somewhat like this:

A layer of corn starch is layed down, then the jet squirts out the first layer of the design with glue (like an inkjet printer works), then another layer of corn starch is layed down, then more glue. So you essentially have layers of corn starch glued together.



So if you were the kid who ate ALL the paste, then perhaps you could eat it.

It really doesn't sound all that palatable. I think I'll go look in the fridge. https://www.nopistons.com/forums/pub...DIR#>/40oz.gif

Think an ABS plastic throttle body would hold up with cold air ducted to it? (n/a)

yeah at my high school we had a 3d printer in our drafting room, used it pretty often the pieces arent too durable really though...

I ask:



he answer:

I'm familiar with vapid prostitutes. Sounds close, does that count?
