 The first idea was to make a 3D printer which has double extruder controller. First syringe extruder should provide the more rigid amount of material(structure) and the second one should be more flexible(surface). I made my gelatine-based biomaterial with different ratios. I basically keep the same amount of water and glycerine ratio and systematically increase gelatine ratio(1-2-4-8). But despite my many trials when every ratio of gelatine-based materials interface with each other lost their shape and they harmonized with each other. Then I try with corn starch-based bio-material. Starch-based bio-material performance well together.

 As you can see from the chart, ı stabilize the amount of water and glycerine and only play with the gelatine amount.

 First ı tried diffrent ratio's. Turned out for ratio 3/4 water gelation is a good performance.

 For control The machine I downloaded [[http://www.pronterface.com/|[[http://www.pronterface.com/|printrun]]]] which is a 3D printing host software suite\\
 which talks to your printer and handles the printing process.

+But this ss for normal fdm settings. What we should is that turn off the bed temp. and extruder temp.

 The idea is to first remove filament extruder and replace with my new syringe extruder design. When the servo motor of the extruder moves extra structure that ı designed would push the syringes and create a shape by following pipes.

+so when you remove the filament extruder, you have to run the machine without heating the extruder heat. That's why you have to use G-code m302 code.

+====== Design syringe extruder ======
+There are not many syringe extruder example in the internet actually. I actually used [[https://www.thingiverse.com/thing:475841|this design]] and changed as 3d files to 2d to cut with the laser cutter.

+I took the section views of the parts and extended as one pieces also for carry two syringe at the same time.
