3D Printing with Two Merging Reacting Jets

alt alt The work done by Dr. Yong Huang's team under a NSF GOALI collaboration between the University of Florida, Gainesville and MicroFab Technologies appears in Volume 31 of Additive Manufacturing. The article by Shinichi Sakurada, Marc Sole-Gras, Kyle Christensen, David B. Wallace, and Yong Huang is titled "Liquid-absorbing system-assisted intersecting jets printing of soft structures from reactive biomaterials". This novel approach for 3D printing avoids premixing of the reactive components before deposition. By using two intersecting jets printing, reactive materials are dispensed separately, colliding and mixing with each other in air before landing on a previously deposited layer. Different 3D structures have been successfully printed using intersecting jets printing from sodium alginate and calcium chloride inks achieving a 2.5 height-diameter ratio. This printing technology does not influence the post-printing cell viability while printing 3T3 cells, demonstrating its promising potential for bioprinting applications.

Ink-Jet Printing of Neuronal and Other Types of Cells

Dr. Patrick Smith's research group at the University of Sheffield used MicroFab's Jetlab® printing system to demonstrate ink-jet printing of biological and neuronal cells. The precise printing technique can be used for lab-on-chip technologies and to fabricate neural networks for fundamental neuroscience studies and applications. “Ink-jet printing can be used to produce finer neuronal networks than produced by other techniques since the printed cells produce longer neural processes,” Smith explains.

3D printed micro-rockets for drug delivery

Xiubo Zhao from The Department of Chemical and Biological Engineering at Sheffield University has created microscopic swimming devices using MicroFab's Jetlab® printing systems. Thetiny rockets, which measure 300 by 100 microns, actually create their own thrust, enabling them to swim through bio fluids. How? A form of inkjet 3D printing is used to deposit a solution of dissolved silk mixed with an enzyme called catalase. Layers of dissolved silk mixed with an enzyme called catalase are built up with other methanol layers by the MicroFab's drop-on-demand printer. A chemical reaction between the methanol and the solution forms the rigid rocket shape of the device, trapping the enzyme within a silk lattice. The catalase then reacts with fuel molecules, producing bubbles which propel the rocket forward.

Survivability of ink-jet encapsulated cells for Tissue Engineering

alt MicroFab, in ongoing collaboration with Wake Forest Institute of Regenerative Medicine (WFIRM), demonstrated 7-day survival post printing & encapsulation. These experiments used a custom ink-jet Bioprinter built by MicroFab and installed at WFIRM.
