This instructable follows a new set of adventures 3DigtalCooks food printing adventures with multimaterial food pastes. This was born with the idea of being able to blend flavors during a print. But for that. We need first to be able to control it ;)
My inner critic told me keep it easy bro, that is why I decided to test everything first using colors. Simpler to spot how well is printing.
The printer used for the experiments is Pinya3.
Instead of using different nozzles, I decided to workout my newbie machining skills to made nozzle/s that handle the same material without offsets.
The first nozzle tested is a coaxial nozzle. This is a nozzle withing another nozzle where the materials are not in contacted until they are extruded.
Shout out to Will Patrick for sharing his idea with me an making this possible!
It uses 1/8" barbed threaded (10-32) connector for the tubes.
Please check the video for a better look at it!
