Can some engineer go engineer up a new Reprap model based off of the Z-Corp's true color printers?

Why hasn't this happened yet? Z-Corp has had these printing types out far long enough, haven't they?

Also, the cost would put it outside the price range for the hobbyists who typically build/use Repraps.

I never said copy it exactly? You don't get sued if you just go by their general idea.

Z-Corp uses a different kind of 'toner' than just plastic, use something like that and go from there.

Who cares, I want a color printer that actually prints in 390,000 colors, or at least 256... I just got a new job and can afford it eventually.

For the record, I'm a 3d modeler, not an engineer.

So if you can afford it, buy a Z-Corp printer.

The issue is that the expensive part of what you want is the extrusion head. That's the part that is patented and there isn't another cheaper alternative to that part that can achieve similar color range. And that's an extremely difficult and expensive part to fabricate, not something you can print out on a Reprap. So unless you can basically afford a Z-Corp printer already, you can't afford to build a color Reprap.

No. Z-Corp's patents don't permit the kind of manufacture that is required to build an extruder or print head that Z-Corp uses on their color printers. These patents will not expire until 20 years after the filing date, at the earliest.

And besides, building a multi-color extruder head isn't easy. It's been done, but it's not easy to correctly calibrate, and the results are less than spectacular. Managing the speeds of multiple feeds isn't as straightforward as you'd think.

There are also people experimenting with multi-extruder setups, but it's not possible to mix the colors.

I didn't want to buy a Z-Corp printer cause it is already assembled... :c

I see, so it is not the toner but the head that is what makes the colors meld, much sadface here.

I didn't realize the head was what made it possible, I assumed it was a special new kind of toner.

Z-Corp uses another process: The print head spits out a bonding agent with a dye (it's not dissimilar from common inkjet printers) into a white plasticized powder. It's patented - both the head and the powder - so no one is really able to reproduce it until those patents expire.

No toner involved.

Odd... I could have sworn I said 'toner' not just toner, oh well it was late, here is what I meant to say.

As for the patent on the 'toner', it doesn't need to be exactly the same, just something similar that works in the same way.

Well, the analogous term would be "ink," not "toner." That's how these printers work - like inkjets.

Meh, I like how toner sounds more.
