El Paso, TX, United States

The University of Texas at El Paso is a four-year state university, and is a component institution of the University of Texas System. The school was founded in 1914 as The Texas State School of Mines and Metallurgy, and a mineshaft survives on the mountainous desert campus. It became Texas Western College in 1949, and The University of Texas at El Paso in 1967.In fall 2014, enrollment was 23,079 . UTEP is the largest university in the U.S. with a majority Mexican-American student population .The El Paso, Texas, campus features a one-of-a-kind collection of buildings in the Bhutanese architectural style. The UTEP campus is located on hillsides overlooking the Rio Grande, with Juarez, Mexico, within easy view across the border.Another notable feature of UTEP is its athletic history. UTEP was the first college in any Southern state in the United States to integrate its intercollegiate sports programs. To this date it is the only school in Texas to bring home an NCAA Men's Basketball Championship, which it achieved in 1966. The movie Glory Road recounts this story. Wikipedia.

While NASA explores the power of 3D printing in the development of the next generation space exploration vehicle, a CubeSat Trailblazer was launched in November 2013 that integrated 3D -printed structures with embedded electronics. Space provides a harsh environment necessary to demonstrate the durability of 3D -printed devices with radiation, extreme thermal cycling, and low pressure - all assaulting the structure at the atomic to macroscales. Consequently, devices that are operational in orbit can be relied upon in many terrestrial environments - including many defense and biomedical applications. The 3D -printed CubeSat module (a subsystem occupying approximately 10 % of the total volume offered by the 10∈×∈10∈×∈10-cm CubeSat enclosure) has a substrate that fits specifically into the available volume - exploiting 3D printing to provide volumetric efficiency. Based on the best fabrication technology at the time for 3D -printed electronics, stereolithography (SL), a vat photopolymerization technology, was used to fabricate the dielectric structure, while conductive inks were dispensed in channels to provide the electrical interconnect between components. In spite of the structure passing qualification - including temperature cycling, shock and vibration, and outgas testing - the photocurable materials used in SL do not provide the level of durability required for long-term functionality. Moreover, the conductive inks with low-temperature curing capabilities as required by the SL substrate material are widely known to provide suboptimal performance in terms of conductivity. To address these challenges in future 3D -printed electronics, a next generation machine is under development and being referred to as the multi 3D system, which denotes the use of multiple technologies to produce 3D , multi-material, multifunctional devices. Based on an extrusion process necessary to replace photocurable polymers with thermoplastics, a material extrusion system based on fused deposition modeling (FDM) technology has been developed that integrates other technologies to compensate for FDM's deficiencies in surface finish, minimum dimensional feature size, and porosity. Additionally, to minimize the use of conductive inks, a novel thermal embedding technology submerges copper wires into the thermoplastic dielectric structures during FDM process interruptions - providing high performance, robust interconnect, and ground planes - and serendipitously improving the mechanical properties of the structure. This paper compares and contrasts stereolithography used for 3D -printed electronics with the FDM-based system through experimental results and demonstrates an automated FDM-based process for producing features not achievable with FDM alone. In addition to the possibility of using direct write for electronic circuitry, the novel fabrication uses thermoplastics and copper wires that offer a substantial improvement in terms of performance and durability of 3D -printed electronics. © 2014 Springer-Verlag London.

Additive manufacturing (AM), often called 3D printing, has received much attention recently with impressive demonstrations ranging from musical instruments, to vehicles, to housing components or even entire buildings. Although it has been argued that 3D printing could be the future of manufacturing, the potential and applicability of these methods for creating functional electronics at RF / microwave frequency remain largely unexplored. © 2014 IEEE.

It has been more than three decades since stereolithography began to emerge in various forms of additive manufacturing and 3D printing. Today these technologies are proliferating worldwide in various forms of advanced manufacturing. The largest segment of the 3D printing market today involves various polymer component fabrications, particularly complex structures not attainable by other manufacturing methods. Conventional printer head systems have also been adapted to selectively print various speciated human cells and special molecules in attempts to construct human organs, beginning with skin and various tissue patches. These efforts are discussed along with metal and alloy fabrication of a variety of implant and bone replacement components by creating powder layers, which are selectively melted into complex forms (such as foams and other open-cellular structures) using laser and electron beams directed by CAD software. Efforts to create a “living implant” by bone ingrowth and eventual vascularization within these implants will be discussed briefly. Novel printer heads for direct metal droplet deposition as in other 3D printing systems are briefly described since these concepts will allow for the eventual fabrication of very large and complex products, including automotive and aerospace structures and components. © 2016
