The Use of Sugar Glass Scaffolds for 3D Printing

By Caleb Sooknanan ‘20 Three-dimensional (3D) printing — a form of additive manufacturing — involves the joining and solidification of material to create objects from computer files. Glasses made of sugars or carbohydrates have become practical materials for printing more complex structures, such as organs, because of their stiffness and durability. These sugar glass materials can be positioned in layers or freeform paths that utilize … Continue reading The Use of Sugar Glass Scaffolds for 3D Printing

Octopus Inspired Synthetic Tissue

By Meghan Bialt-DeCelie ’19 One of the most notable features of cephalopods like octopus and cuttlefish is their ability to quickly camouflage with the environment by changing the color and texture of their skin. They are able to dynamically adapt the textures of their skin by contracting muscular hydrostat structures referred to as papillae. Researchers, led by James Pikul PhD, from Cornell University took inspiration … Continue reading Octopus Inspired Synthetic Tissue

Controlled Degradation of 3-D Printed Biomaterials

By Meghan Bialt-DeCelie ’19 The explosion of 3-D printing technologies allows custom and precise structures to be made quickly and inexpensively. Researchers led by Thomas Valentin from Brown University utilize stereolithographic 3-D printing to create biocompatible structures that could degrade in response to chemical cues. The technique of stereolithography involves shooting photons at unpolymerized materials causing them to form crosslinks with themselves to build a … Continue reading Controlled Degradation of 3-D Printed Biomaterials
