The material extrusion (ME) additive manufacturing process is extensively used in hobbyist and prototyping applications, but it is not always suitable for the fabrication of end-use components. The thermal characteristics of the layer-by-layer deposition results [...]
E-beam additive manufacturing is a rapidly growing industry. Electron guns capable of reaching higher energies and higher average power can enable larger melt pools, higher production speed, and permit broader range of materials for metal [...]
This paper discusses a novel additive manufacturing technique that was developed in order to 3D print polymeric parts with tunable properties. This technique, known as 4D-Rheoprinting, can be applied to a number of common additive [...]
Achieving sub-wavelength spatial variations in the relative permittivity εr and permeability μr to control the propagation of the electromagnetic radiation opens up many opportunities for the development of new devices with improved or novel functionality [...]

One of the great opportunities in additive manufacturing is the ability to manufacture complex optimized internal geometries such as lattices and honeycombs for space filling applications. Some obvious applications including sandwich panels for lightweighting and [...]
Traditional manufacturing methods contain removing excess materials by trimming, cutting and sanding to get the projected shapes; however, additive manufacturing contain direct manufacturing of the objects utilizing computer assisted design model by adding a layer [...]
Recently, the proportion of 3D printing technology in the electronics industry is expected to average 50% in 2030. It is expected that the 3D printing manufacturing method will be introduced in earnest depending on the [...]
Recent advances in the field of additive manufacturing have utilized electronic circuits to develop high-valued functional devices. Here we present a novel approach to fabricate viscoelastic polymer-free metal ink and RF passive structures via material-extruded [...]

In recent years there has been a meteoric rise in interest and research in the field of metal additive manufacturing in both academia and industry. Such processes represent an attractive alternative to more traditional metal [...]
We demonstrate a 3D computational fluid dynamic (CFD) simulation of the Fused Deposition Modeling (FDM) process. Extrusion-based additive manufacturing technologies, such as FDM, are advancing rapidly as applications of rapid prototyping for finished product development [...]
The additive manufacturing laboratory at Frostburg State University utilizes three different 3D printers, studied and leaned the error in tolerance, and develop a method to approach parts with minimal tolerance error, and successfully produce the [...]
Fused deposition modeling (FDM) is the most common additive manufacturing technique for the production of cost effective polymers and composites. In fact, half million FDM systems were sold between 2013 and 2015. FDM is used [...]
