3D Printing

March 28, 2017

Abstract:

We present a new strategy for the fabrication of artificial skeletal muscle tissue with functional morphologies based on an innovative 3D bioprinting approach. The methodology is based on a microfluidic printing head coupled to a co-axial needle extruder for h...

Abstract:

A rapid and high-resolution bioprinter based on a capillary coaxial microfluidic printer head and vacuum substrate, was conceived and built up in this work. We demonstrate the printing of porous (400 μm pitch) 3D bio-scaffolds made from calcium alginate microf...

Abstract:

Microfluidic components capable of mimicking the functions of electronic circuit elements are critical to applications including soft robots [1] and biochemical fluids processing [2-4]. The emergence of state-of-the-art additive manufacturing or “three-dimensi...

March 4, 2017

Abstract:

This paper reports the first demonstration of a fully additively manufactured, miniature diaphragm vacuum pump. Using polyjet 3-D printing technology with 42 μm XY pixelation and 25 μm layer height, a single-stage vacuum pump design with active valves that has...
