What advantages does a mechanical extrusion system like the one designed for V1 and E4Life have over a pneumatic extrusion system?
A mechanical system allows extrusion of material with greater precision, the precision of extrusion is 1 microliter and the minimum diameter of the syringe of 150 microns (0.15mm). Additionally, the mechanical positioning allows us to make injections within a scaffold not only in the pore we want but also at the desired height and layer. This possibility is not allowed with pneumatic positioning.
