3-DIY: Printing your own bioprinter
Researchers at Carnegie Mellon University have developed a low-cost 3-D bioprinter by modifying a standard desktop 3-D printer, and they have released the breakthrough designs as open source so that anyone can build their own system. The researchers – Materials Science and Engineering (MSE) and Biomedical Engineering (BME) Associate Professor Adam Feinberg, BME postdoctoral fellow TJ Hinton, and Kira Pusch, a recent graduate of the MSE undergraduate program – recently published a paper in the journal HardwareX that contains complete instructions for printing and installing the syringe-based, large volume extruder (LVE) to modify any typical, commercial plastic printer.
“What we’ve created,” says Pusch, “is a large volume syringe pump extruder that works with almost any open source fused deposition modeling (FDM) printer. This means that it’s an inexpensive and relatively easy adaptation for people who use 3-D printers.”
As the researchers explain in their paper, “Large volume syringe pump extruder for desktop 3D printers,” most commercial 3-D bioprinters currently on the market range in cost from $10,000 to more than $200,000 and are typically proprietary machines, closed source, and difficult to modify.
