3-D Jet Writing vs. 3-D Printing
May 8, 2018 | Terry Sharrer
In order to make more authentically-sized tissues for researching anti-cancer therapeutics, Purdue University and University of Michigan researchers have used 3-D “writing” to achieve the right scale. “A 3D jet writer can produce polymer microtissues as they are shaped in the body, but on a smaller, more authentic scale than a 3D printer. Microtissue pore sizes are large enough for cells to enter the polymer structure just as they would a system in the body. This fine-tuned form of electrospinning uses a charged syringe containing a polymer solution to draw out a fiber that is then deposited onto a plate to form a structure. This structure is a scaffold that facilitates cell activity.” MORE
