Selected area laser deposition (SALD) has been used to deposit carbon from methane, hydrogen, oxygen, and argon mixtures using a third generation deposition system. The effect of two laser scanning hardware/software ...

Metal and ceramic flexure specimens were fabricated using a photopolymer-based rapid prototyping technique. Photosensitive resins (inks) were produced by dispersing 50 - 55 vol% metal or ceramic powders in a photopolymer ...

Research suggests that topology and build parameters in Fused Filament Fabrication (FFF) play a vital role in determining mechanical properties of parts produced by this technique. In particular, the use of 2D layers ...

The mechanical performance of 3D printed components is highly dependent upon the orientation of the part relative to the build plane. Specifically for extrusion-based printing systems, the bond between successive layers ...

We present a novel method for liquid metal drop-on-demand (DOD) additive manufacturing of three-dimensional (3D) solid metal structures. This method relies on magnetohydrodynamic (MHD)-based droplet generation. Specifically, ...

Additive manufacturing (AM), or 3D printing has enjoyed a recent surge of attention over the past decade. AM is a process in which digital 3D design data is used as input to build physical objects by combining sequence ...

This paper presents the Additive Manufacturing (AM) of glass using a fiber-fed process. Glass fiber with a diameter of 100 μm is fed into a laser generated melt pool. A CO2 laser beam is focused on the intersection between ...

Directionally solidified components, such as single crystal turbine blades, are typically grown using shell molds prepared using a lost wax process that begins with injection-molded wax positives. These positives have ...

This study aims to design a green additive approach for the fabrication of controlled porosity on hydrogels. Although hydrogels have been of common use in tissue engineering, the generation of controllable porosity remains ...

Organosolv lignin, a natural cross-linked phenolic wood polymer is a by-product of the pulping process in the paper industry. It is a renewable organic natural product with potential application in many areas. It has ...
