Open Source Bioprinter
The 'Nydus One Bioprinter' is an extrusion-based Bioprinter. It operates via a controllable mechanical press, to extrude cell-laden bioinks. Basis for the Bioprinter is a remixed version of the RepRap Prusa i3 MK2-X. The printer is capable of printing all three common cell sources: cell-lines, primary tissue and stem cells. To operate the Bioprinter, Dennis Ogiermann has written a "Composer". This open source pathplanning tool allows to dispense into standarized container and allows repetitive experiment designs. The 'Nydus One Bioprinter' was established using a experimental 'Microgel Approach'. Main idea of the approach is the use of a thermoreversible gelatin bath (called Slurry Bath) to print objects with complex geometry. The approach was published by Hinton et al. in 2015 (see Sources).
