While 3D printing has already been used to create entire body parts, printers that can extrude living cells are still very expensive. Clinical researchers at the*Feinstein Institute for Medical Research in Manhasset, NY, a part of **rth Shore-LIJ Health System, have partnered with folks from MakerBot to use off-the-shelf 3D printers to create personalized functional tracheas for needy patients.

The team decided to try using MakerBot’s standard PLA Filament, a*resin made from sugar corn, as a scaffold to grow the cartilage tissue. The team built a bunch of windpipe models, taking them to***rth Shore-LIJ surgeons that specialize in trachea surgeries for evaluation. After repeated changes and modifications, they had created more than 100 versions of the trachea within about a month. Because the printing process involves heating up the PLA Filament, it automatically comes out sterilized and ready for the next step

Pressing forward, they used a modified MakerBot Replicator 2X Experimental 3D printer that has two extruders to apply a “bio-ink” full of living cells onto the scaffold. Placing the resulting trachea into a bioreactor allows it to promote cellular growth over the scaffold in preparation for implantation.

Here’s a video about the project:
