Achieving Molecular Orientation in Thermally Extruded 3D Printed Objects

Biofabrication 2019 Volue 11, Number 4, Article 045004

3D printing is used to fabricate tissue scaffolds. The polymer chains in these objects are typically unoriented. The mechanical properties of these scaffolds can be significantly enhanced by proper alignment of the polymer chains. But, post-processing routes to increase orientation can be limited by the geometry of the printed object. Here we show that it is possible to orient the polymer chains during printing by optimizing the printing parameters to take advantage of the flow characteristics of the polymer. This is demonstrated by printing a polymeric scaffold for meniscus regeneration using poly(desaminotyrosyl-tyrosine dodecyl dodecanedioate), poly(DTD DD). Alignment of the polymer…
