3D Bioplotter Research Papers

We have printed microscale 3-dimensional tissue scaffolds using cellulose acetate (CA) for the first time and produced a range of pore sizes ranging from 99 to 608 μm that are potentially favorable for tissue engineering. In the process we have elucidated some of the formulation-fabrication-morphology relationships which enabled advancements in ink development, optimization of fabrication parameters, and morphological control. The challenges for printing very small pores were discussed and improved by adjustment of printing conditions and use of a rheological modifier. We believe this study will increase the knowledge base for additive manufacturing of CA and enable further research into the…

Distributed sensing of environmental parameters is going towards solutions that are more efficient by taking inspiration from flying plant seeds. Yet, present technologies mostly rely on electronics, and they are often heavy and not biodegradable. Here, we develop a biodegradable and porous material, based on cellulose acetate and lignin, and characterize its degree of porosity. We use this material to 3D print lightweight and porous artificial fliers inspired by Ailanthus altissima seeds. By 3D printing, we can tailor in a precise way the morphology of the artificial flier that strongly influences its aerodynamic behavior. We add a cellulose-based photonic crystal…
