Abstract

Additive manufacturing (AM), or three-dimensional (3D) printing as it is more commonly known, is defined as the process of joining materials and creating objects by melting, sintering, or fusing material in a layer-by-layer fashion coordinated via 3D model data.1 Subtractive, or traditional, manufacturing methodologies often consist of machining/removing material—like a sculptor—or forming material through the application of pressure—like a potter. Conversely, in an AM process, material is added in individual volume elements and built up in a way similar to interlocking building blocks, but with volume elements that are typically the size of a grain of sand. The additive process often involves less waste when compared to subtractive techniques because material is only added when and where it is needed. Adjustments to the final structure are relatively straightforward and can be simply achieved by adjusting the 3D computer model. This makes the technology much more flexible than traditional, subtractive techniques where new tooling or forming equipment is usually needed to accommodate design changes. Also, the AM processes are beneficial because they permit the fabrication of unique geometries, such as miniaturized metal lattice structures, that cannot be achieved using traditional techniques. An example of a metal lattice structure is the Eiffelmore »« less

HYBRID MANUFACTURING TECHNIQUE USING LARGE-SCALE ADDITIVE MANUFACTURING AND COMPRESSION MOLDING FOR HIGH PERFORMANCE COMPOSITES

Conference Kumar, Vipin ; Kim, Pum ; Kishore, Vidya ; ...

Additive Manufacturing (AM) or 3-D printing has moved from small-scale prototypes to large-scale functional structures. With the introduction of large-scale 3D printers into the market a new industry has been born. For the first time, we are presenting the idea of preparing large-scale 3-D printed β-stage preforms to be used in traditional compression molding (CM) manufacturing technique to prepare final functional structures. Short carbon fiber (CF) reinforced material acrylonitrile butadiene Styrene i.e. ABS with 20% CF is used in present work. It is shown that highly aligned 3D printed short carbon fiber composite maintains its orientation after compression molding. Amore »« less

Additive Manufacturing: The Rise of a Technology and the Need for Quality Control and Inspection Techniques

Journal Article Hassen, Ahmed A. ; Kirka, Michael M. - Materials Evaluation

Additive manufacturing (AM) technology, also known as three-dimensional (3D) printing, rapid prototyping (RP), or solid free forms (SFF), was developed back in the early 1980s. The technology was quickly commercialized in the late 1980s, and since then, the technology has been widely used in different applications at several industrial sectors. AM offers distinct advantages from traditional, subtractive manufacturing techniques. Traditional subtractive manufacturing techniques, including milling, drilling, and turning, are techniques that start with a large block of stock material, which is then subtracted from until the final desired product is reached, leaving much of the initial block as wasted scrap.more »« less

Non-destructive simulation of node defects in additively manufactured lattice structures

Journal Article Lozanovski, Bill ; Downing, David ; Tino, Rance ; ... - Additive Manufacturing

Additive Manufacturing (AM), commonly referred to as 3D printing, offers the ability to not only fabricate geometrically complex lattice structures but parts in which lattice topologies in-fill volumes bounded by complex surface geometries. However, current AM processes produce defects on the strut and node elements which make up the lattice structure. This creates an inherent difference between the as-designed and as-fabricated geometries, which negatively affects predictions (via numerical simulation) of the lattice’s mechanical performance. Although experimental and numerical analysis of an AM lattice’s bulk structure, unit cell and struts have been performed, there exists almost no research data on themore »« less

Design and Manufacture of Tunable Permanent Magnet Based Quadrupole for Next Generation Electron-Ion Colliders [Slides]

Technical Report Choi, Heeju ; Jasinski, Melania ; Haley, Lori ; ...

The goal of this project is to design and construct of a prototype of quadrupole permanent magnet for the magnet transport lattice for an electron-ion collider. The technical objectives are not only to achieve the field gradient of 34.42T/m in the region of interest, at a radius 16.0mm, relative to the quadrupole axis (z-axis), but also lower the unwanted field harmonics below one unit out of 10,000, especially for Sextupole, Octupole, and Decapole components. The innovation is 1) modular design for cost saving, and 2) adjusting mechanism of each modular magnet for field tuning. The 300-mm long, quadrupole magnet assemblymore »« less

Direct 3D femtosecond laser manufacturing of SOFC

Technical Report Liu, Jian

Advanced Fossil Energy technologies allow the Nation to use its indigenous fossil energy resources more wisely, cleanly, and efficiently. SOFCs are modular, scalable, and efficient, and are considered to be the next generation fuel cell technology. However, Due to the limitations in terms of spatial control and high reproducibility of microstructures involving traditional screen printing, slurry pasting, and dip coating methods, there has been of late an increasing interest in inkjet printing and other direct-write additive processes. Based on our success in developing a variety of award winning high energy and high power ultrafast fiber lasers and our pioneered workmore »« less
