As part of a university research project, [Vimal Patel] was asked to make something out of biodegradable 3D printer filament. The theme of the project is called Monomateriality — making products out of a single material to aid the manufacturing process, and after the product is used, ease of recycling.
He started by experimenting with the 3D printer filament in the UP 3D printers the university had on hand. But he wasn’t content with the layer-by-layer deposition method that all FDM printers use. He was more curious about free form deposition modeling — extruding material along multiple axes at once.
Unfortunately the project budget didn’t afford him a 6-axis robotic arm 3D printing setup like this to complete the project. But he was able to build his own custom extruder using a hot glue gun, and some LEGO. It’s kind of like a 3Doodler, but much more bulky.
Using standard LEGO parts he was able to build an attachment for the hot glue gun to feed the 3mm diameter biodegradable filament through the nozzle. He’s uploaded the design files over at rebrickable.com to share with the world.
While the end product he designed (a bicycle helmet) isn’t too realistic, [Vimal’s] more excited at the accessibility of the making process — after all, you just need a hot glue gun and some LEGO.

Remember the Kickstarter for the 3Doodler? Well they have just started shipping, and a hackerspace called Open Garage in Belgium just got theirs! Like any good hackerspace after playing with it they took it apart and posted pictures.
This is great because in our original coverage on the 3Doodler, we wondered what it looked on the inside, and whether it could be adapted to use with a CNC machine to make a giant 3D printer. Garage Lab delivered on both.
Stick around after the break to see the innards, and the first test print using a CNC mill!

Here’s something that’s making its way to the top of our, “why didn’t we think of that” list. It’s called 3Doodler, a device based on the plastic extrusion technology found in 3D printers stuffed into a pen that fits in the palm of your hand.
If you’re familiar with 3D printers, the design of the 3Doodler should come as second nature to you. Inside this electronic plastic-melting pen is a small motor that forces 3mm ABS or PLA filament through a heated nozzle. With the 3Doodler, you can draw in three dimensions by simply lifting the tip of the 3Doodler into the air.
While 3Doodler is obviously aimed at creating plastic objects by hand, we’re wondering if this device could be successfully adapted to work with 3D printers. The 3Doodler team put a very, very small and inexpensive extruder and hot end inside the 3Doodler, and they’ve got something on their hands we’d love to tear apart just to see how it ticks.
You can see the 3Doodler introduction video after the break.
