FIGURE 4.10
Biphasic and mixed CPC-alginate scaffolds. (a) CAD models and realized scaffolds in ( b) wet
and (c) dry state are shown. The biphasic CPC-alginate scaffold (left) was produced by alter-
nate plotting of P-CPC and a high-concentrated alginate-PVA paste through nozzles with an
inner diameter of 610 µm (printing speed: 3 mm/s, dosing air pressure: 5.0 bar for the P-CPC
and 7.4 bar for the alginate-PVA paste). For fabrication of the mixed CPC-alginate scaffold
(right), a CPC-alginate-PVA paste was plotted through a nozzle with inner diameter of 610 µm
(printing speed: 3 mm/s, dosing air pressure: 8.5 bar).
