Printrbot and Polar3D develop a new conveyor belt 3D printer

While it isn’t a new concept, the conveyor belt 3D printer idea is gaining more and more popularity this year. Prove of this ‘trend’ popping up is the recent launching of the Printrbelt 3D printer, which just debuted last week after its successful development by Printrbot and Polar 3D.

The Printrbelt’s printhead works by moving on an X axis angled at 35° to the Z axis. Z axis is composed of a heated print bed conveyor belt; It is compact and has extensive size, but the real beauty of it is their cloud platform allows you to have a single printer that takes the place of many printers. So instead of having a whole slew of printers printing all your pieces, you can send all your files to the print qeue for the printer belt. The printer will go and print all of them successively and just move down the belt and fall off.

Actually, Brook Drumm from Printrbot showed the Printrbelt before the machine’s first public demonstration at the International Society for Technology in Education (ISTE) celebrated last week in Texas. Drumm’s Youtube Description of the Printrbot Printrbelt teaser actually says:

“The Printrbot Printrbelt allows for very long prints, multiple copies of one print, or a whole project of files to be printed in one shot. It is a beta, but too fun to keep to ourselves”.

You can see Printrbelt at work in the video below:

The Printrbelt Conveyor belt 3D printer is available by pre order on Printrbot’s site. It is currently on sale for $1,699.15 (normal price will be $1,999). Starting in 2 weeks, Printrbot will be fabricating the machines one at a time and shipping them in order; Then, the company plans to increase production until delivering times drops to the next day. Printrbot is also running a general Fourth of July sale! – everything is 15% off until July 4th at midnight PST.

    Thanks like the new tech

  2. Jared Heifetz says

    That is a very different kind of model. Didn’t realize there were more out of the box styles

    This is really cool. I wonder if you have seen the Blackbelt 3D printer. It’s like this but on a much larger scale.
    It makes me want to buy an old treadmill off of Craig’s List and get modding! lol

  4. Richard Bynum says

    I’ve never seen a printer like that before. Is it able to print taller projects or is it limited to shallow prints because the strange way the (x) is angled? Why would they do that? Seems like it would limit what it could print. But then again, I’m new so I know I must be missing something! haha.
