3Drag Printing Chocolate

3DRAG (aka Velleman K8200) is still being used in some projects like this one where it extrudes chocolate paste. Omnomnomnom...

Here are some Halloween decorations:





Here is the general overview of chocolate printing ... mmmm ... chocolaaateeeeee  ...




Oh yes, bread and 3d printed nutella, breakfast of the champions!

3D Printing food by FabLab Maastricht

Thomas Sanladerer made this interesting video on 3d Printshow Berlin 2015 about 3d printing food items on a machine developed by FabLab Maastricht. They also involve local chefs and create food silicone molds for food pieces.

Printrbot Paste Extruder

Brook Drumm of Printrbot posted on his G+ about Printrbot Paste Extruder.
He announced some possible interesting future implementations of this type of extruder:

• Heated syringe (chocolate and human cells??)
• Printable files to convert to dual chamber syringe with quick drying silicone and a mixer nozzle (off the shelf stuff)
• quick setting UV resin paste with light on the end of the tip 
• conversion to a Bowden type setup so the extruder can sit on the table getting all that mass off the printer
• a sister extruder that will push moist clay through a bigger hose for big clay prints ready to fire
• large pneumatically assisted reservoir for longer/bigger prints feeding a screw drive print head
• new material mixes for sturdier paste and firmer clay to support the weight of the print (cellulose, etc)
• metal construction to get rid of laser cut wood 
• dabble in concrete then scale it up
• -ugar paste for edible goodies
• shortbread cookie recipes for cookie paste
• pancakes, anyone?
• 3d jello art
• crazy ideas from the community welcomed here!!

3d printed extruder for continuous clay shapes

Scot A. Brown published a post on 3d printed rotational extruder "Rotruder" that produces continuous stream of clay objects. The rotating parts of the extruder form a mold when they are closing together.
Interesting concept and example of mold+extruder being made by with 3d printed parts. I think it could be used with other pasty materials or even food.
I have not found any design or technical documentation.It would be interesting to see the mechanism of power transmission that turns the six mold wheels.

Lin3s simple design tool that works great for compressed air extruders

Lin3s is a simple CAD web tool that enables you to create 3d objects from simle line drawings. It works great for paste extrusion and air pressure extruders. Lin3s is developed by 3digitalscooks crew and they use it in their 3d printed food projects. Great work!

Here is a basic tutorial on how to use Lin3s with main options:




... and here is the result 3d printed with hummus (yes, hummus!) mmmm on nom nom ...

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

3D printing with locally dug clay, builder’s silicon, wax, sugar frosting, sugar sticks, sugar fondant and wood paste

Jonathan Keep held a workshop at Burg-Halle University in Halle near Leipzig, Germany. He demonstrated 3D printing with locally dug clay, builder’s silicon, wax, sugar frosting, sugar sticks, sugar fondant and wood paste.

Keep is well known for his work with Delta printers and special extruders on clay and other materials such as chocolate.
