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 modified 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 containers and cell culture vessels 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).

Composer issues
- depending on object(geometry) to be printed and the print settings, some prints might not work (trial and error, may work with some settings, but we don't know which settings are appropriate for what kind of structure)
- the pathplanning seems to be off (Old Composer issue, solved in the new one!)
- If you change the number of objects-to-be-printed later on, the composer will not recognize this and just print the initial number of constructs. To solve this issue, exit the composer and open again

OSF Repository
To allow sharing the required soft- and hardware, we have created an OSF repository: Open Science Framework Bioprinter Project
