As part of Francis Bitonti and Xuedi Chen's vertical studio at the architecture school of Rensselaer Polytechnic Institute, teams of 3 were given the task to design a paste extruding 3d printer. Our team initially put together a Printrbot Simple Maker's Edition, and using the basic concepts behind this printer, as well as inspiration drawn from the PiMaker, designed our own.
The main features of the PiBot are a flexible dual extruder system combined with a rotating polar bed. This grants us the ability to both print one object with a combination of materials from the two extruders, as well as print two of the same object at the same time, due to the rotating bed.
Team: Nicholas Nord, Hiroki Sawai, Lauren Famularo

I'm developing my own 3d polar printer. I see the pimaker and your printer. Both are very good jobs!

I'm very interested in your bed leveling. How it's works?


Really awesome job guys! super interested to see where you guys go with this technology. I like the idea of using the Tubes combined with syringes. I think there is room to grow your idea as well.. It reminds me of a mix between my @BotBQ extruder and @3DigitalCooks #PLYUMP extruder. Great work!

Love it!!! Let me know if you need anything.
