A RAPID PROTOTYPING METHOD FOR CONSTRUCTING A COMPLEX THREE-DIMENSIONAL SUBSTRATE

TL;DRAbstract

Cell culturing on three-dimensional structures has increased the possibilities in tissue engineering and bioreactor research. These structures enable cells to differentiate, proliferate, mobilize, and function in a conformation that more accurately mimics in vivo conditions. Computer generated models aid in development and rapid alteration of three-dimensional cell substrates, defining their internal structure as well as their external morphology. The rapid transition from substrate design to a viable culture is imperative to quickly advance research in biomedical and tissue engineering applications. The aim of this thesis is to investigate the feasibility of a rapid prototyping process by selectively cross-linking and assembling biocompatible films. This investigation revealed that selectively cross-linking and layering gelatin films could produce a three-dimensional substrate with a defined structure after dissolving uncross-linked gelatin. The study also revealed that freeze-drying
