That was my first step in this quest, second step was starting this thread. That does sound like a great project. Iād like to study a few alternatives as well. I am also thinking this is something that could use the automated syringe pump thingy that Ali Afshar (Hackscience) showed off in Santiago.
Hi @punkish,
There is also a cool recent extruder design from the GOSH community, that can be mounted on any 3d printer or CNC stage: http://irnas.eu/vitaprint
It allows temperature control of the liquid, which is really important for good results in bioprinting. Depends how low-cost DIY you want to go
Cheers,
Tobey
