PiBot rotary bed 3d printer with dual paste extruder

PiBot is polar movement 3d printer that can print with paste materials from dual syringe extruders. It is inspired by PiMaker polar 3d printer which has very detailed build instructions.

From project description:

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

Video updates on Theta polar 3d printer

Theta printer has unique design, you can check the first post about it here:

http://diy3dprinting.blogspot.com/2013/11/theta-printer-4-extruder-polar-3d.html

Here are some videos that show how the printer construction is progressing:




Simultaneous printing on Theta. The blue plastic is PLA and the yellow is ABS.



Two extruders printing on the same object at the same time.

First print results in PLA and ABS at the same time on same object

Update (12.1.2014.):

here is a new video and successful print of the iconic Octopus:

From video description:

Testing the new firmware by printing an octopus. This print took about 1.5 hours with a feedrate of 20 °/s. In this case, thats roughly 55 mm/s. This printer should be capable of at least 40 °/s.

Update (21.8.2014.):

Theta was submitted for Hackaday prize contest:

R-360 simple open source polar 3d printer

R-360 features:

• Cheap when compared to any other existing printers with a large printing area and speed. This must make more people easier to have it.
• Our 3D printer consists of far fewer parts. Compared to RepRap, it contains only one third of the parts. So it's really easy to build it even if you are a beginner. We assemble the main parts of the printer, saving you from all the hard work, so you can be up and running in one hour. No soldering necessary, just plug the main parts together with a few bolts and you’re ready to print! We will upload all instruction on our website.
• The bed is a disc and turns 360 degrees. This is unique and fun! Also this keeps the bed perfectly level using a unique leveling system. We invented this bed shape to get rid of extra bearings, belts, rods and plastic parts.
• The rotating bed makes it ideal for 3D scanning applications. Scanning turntable mode is included (3rd party scanner is required)
• We are planning colourful printers, such as orange, sky blue, pink and light green. We also have white and black. This very cute 3D printer would compliment your rooms’ decoration.
• Light but robust! You can travel with it easily! You can take it apart and build it again easily, folding it up into a small, flat traveling size in minutes.
• Fully Modular, we designed it so very easy to change and upgrade any of its parts.

Future plans for R-360:

• Cloud Printing upgrade. Using your Raspberry Pi, you will be able to send prints directly from the internet to your 3D printer, turning it into a networked (wifi if your Raspberry Pi supports it) 3D printer! (Separate Raspberry Pi is required)
• We are planning to add separate 3D scanner upgrade. The disc shaped bed allows us to create for you the next step in 3D printing: the 3D copying machine! A 3D scanner will be able to scan an object and then the 3D printer reproduce it.
• Multi colour printing. Multi colour or multi material upgrade.
• Modular Upgrades: a larger printing area; 30cm printing bed and 30cm printing height, plotter & paste extruder heads, and 3D scanning apparatus.

Theta printer - 4 extruder polar 3d printer in development

Interesting looking polar 3d printer developed by RepRap forum user unlimitedbacon. He calls it "3d printing record player". The rotating circular build plate is called the ϴ ("theta") axis and the swinging arm is called the R axis. They replace the  X and Y coordinates in a standard 3d printer.

Features:

• 4 extruders for multiple colors and materials
• 320 mm print platter (meets or exceeds the area of current RepRaps)
• 80425 mm^2 print area
• 0.084 degrees/step angular resolution (ϴ Axis)
• 0.20 mm/step linear resolution (R Axis)
• it comes in two versions. The lasercut edition and the reprap edition (printed parts and threaded rods)

RepRap Lewis

Printer that was never developed to maturity, but has very interesting and unique design with SCARA arm and circular build platform. It does not need any bearings or non-printable linear systems.I hope someone will finish this project some day.

Blacksmith Printr - rotary 3d printer

Project developer claims that it is the worlds first spinning base 3d printer, but I think he is wrong. There were several other rotation based projects like:

PiMaker - DIY 3D Printer with circular buildplate

WOW!

From project description by wjsteele:

This is the PiMaker 3D Printer. It utilizes the Printrboard set of electronics to drive a circular build plate instead of the standard cartesian coordinate based system of most other 3D printers. The benefit is that it has a very large build volume for it's relative chassis size. In fact, this particular configuration utilizes an 11" build platform (with 10.5" usable) and and 8" height, giving it a build volume over 650 cubic inches.
It utilizes all the sandard firmware and software with the exception of a single post processor script that does the polar conversion. This utility is currently written in C# (Mono.) It's usage is simple... just pass it the name of the file you wish to convert. It will create a backup of the file and rename the new one with the old name. (There are a few more modifications I'll be making to this file, but it works as is right now.)
This whole project is a work in progress, so check back for updates.

There is a detailed video build tutorial:
