article⁄Growth Based Fabrication Techniques for Bacterial Cellulose: Three-Dimensional Grown Membranes and Scaffolding Design for Biological Polymers (2016)
abstract⁄Selfassembling manufacturing for natural polymers is still in its infancy, despite the urgent need for alternatives to fuelbased products. Nonfuel based products, specifically biopolymers, possess exceptional mechanical properties and biodegradability. Bacterial cellulose has proven to be a remarkably versatile biopolymer, gaining attention in a wide variety of applied scientific applications such as electronics, biomedical devices, and tissueengineering. In order to introduce bacterial cellulose as a building material, it is important to develop biofabrication methodologies linked to materialinformed computational modeling and material science. This paper emphasizes the development of threedimensionally grown bacterial cellulose BC membranes for largescale applications, and introduces new manufacturing technologies that combine the fields of biomaterials science, digital fabrication, and materialinformed computational modeling. This paper demonstrates a novel method for bacterial cellulose biosynthesis as well as insitu selfassembly fabrication and scaffolding techniques that are able to control threedimensional shapes and material behavior of BC. Furthermore, it clarifies the factors affecting the biosynthetic pathway of bacterial cellulosesuch as bacteria, environmental conditions, nutrients, and growth mediumby altering the mechanical properties, tensile strength, and thickness of bacterial cellulose. The transformation of the biosynthesis of bacterial cellulose into BCbased biocomposite leads to the creation of new materials with additional functionality and properties. Potential applications range from small architectural components to large structures, thus linking formation and materialization, and achieving a material with specified ranges and gradient conditions, such as hydrophobic or hydrophilic capacity, graded mechanical properties over time, material responsiveness, and biodegradability.
