May 04, 2021 While FDM, SLA, two-photon laser, drop on demand are some of the most popular biofabrication methods, this “From Academia” issue includes three less well-known but trending methods that could be complementary or alternative to the typical 3D bioprinting process. The first article introduces a biofabrication method using ultrasound waves, also known as sonolithography. This gentle method can rapidly generate 2D cell patterns for a variety of materials, as well as act as a complementary technique to additive manufacturing where surface patterning combined with layer‐by‐layer fabrication can facilitate the generation of structures with more internal complexity. However, this method does not allow selectively targeting and manipulating individual cells. The second article addresses exactly that problem with a single cell bioprinting method using short laser pulses, which allow for the precise and efficient selection and positioning of individual mammalian cells, as well as transferring of specific cell/cells to a target surface with precision and high cell viability. The third publication was written in 2017, but we are anticipating the author’s upcoming paper in a few weeks. This paper reviews the principles behind a fabrication technique called melt eletrowriting (or electrostatic writing) and also compares it to an adjacent technique called electrospinning. The author also lists potential biomedical applications of this technique.
“From Academia” features recent, relevant, close to commercialization academic publications. Subjects include but not limited to healthcare 3D printing, 3D bioprinting, and related emerging technologies.
