(a) Overview of the programmable 3D-bioprinting system integrating 3D-EBP with a commercial bioprinter. (b) Illustration of TMV solution impinging onto the μPA from teflon-modified needles. The solution impinging onto the μPA surface without electrowetting (left) keeps a spherical shape without further access/spreading into the microcavities (Cassie-Baxter state), while the droplet impinging with electrowetting (right) selectively wets the underlying cavities (Wenzel state).

Context 1
... 3D electro-bioprinting (3D-EBP) technique has been integrated with a state-of-the-art commercial 3D bioprinter (3D Bioplotter, Envision TEC) by simply connecting a function generator (Agilent 33220A) to the printing nozzle and the substrate as described in Figure 2a. The built-in graphical user interface allowed a highly automated and programmable 3D-EBP with precise control over nozzle pressure, printing distance, array size/density, and solution temperature. ...
Context 2
... syringe was connected during the curing step to continuously flow air through the tip to prevent blockage during the curing process. The hydrophobic coating at the tip was critical to isolate the droplet forming towards the substrate during extrusion (Figure 2b); otherwise the extruded droplets would roll-up to the outer metallic surface causing inconsistency in droplet size and printing failures. ...
