Microstructures to control elasticity in 3D printing

3d Printing for Prototypes of Thin-film Pzt/polymer Microstructures

This work explores the viability of using 3D printing as a rapid-prototyping technique for microrobotic appendages made from thin-film PZT/polymer materials. First, the possibility of integrating piezoelectric materials into millimeter-scale (meso-scale) polymer melt-printed structures was investigated. Next, one specific robot limb geometry was chosen as a basis to compare structural modeling ...

3D printing of biomimetic microstructures for cancer cell migration.

To understand the physical behavior and migration of cancer cells, a 3D in vitro micro-chip in hydrogel was created using 3D projection printing. The micro-chip has a honeycomb branched structure, aiming to mimic 3D vascular morphology to test, monitor, and analyze differences in the behavior of cancer cells (i.e. HeLa) vs. non-cancerous cell lines (i.e. 10 T1/2). The 3D Projection Printing sys...

Finite Scale Microstructures in Nonlocal Elasticity

In this paper we develop a simple one-dimensional model accounting for the formation and growth of globally stable finite scale microstructures. We extend Ericksen’s model [9] of an elastic “bar” with nonconvex energy by including both oscillation-inhibiting and oscillation-forcing terms in the energy functional. The surface energy is modeled by a conventional strain gradient term. The main new...

Masters Thesis: Applying feedback control to improve 3D printing quality

Tion in 3d Printing

The rapid development in additive manufacturing (AM), also known as 3D printing, has brought about potential risk and security issues along with significant benefits. In order to enhance the security level of the 3D printing process, the present research aims to detect and recognize illegal components using deep learning. In this work, we collected a dataset of 61,340 2D images (28×28 for each ...
