We investigate the possibility of additively manufacturing fibrous sound absorbers using fused deposition modeling. Two methods for 3D printing fibers are proposed. The fiber bridging method involves extruding filament between two points with no underlying supports. extrude-and-pull a droplet before pulling away extruder rapidly to generate thin fibers. Both can produce aspect ratios greater th...

Lightweight structures with an internal lattice infill and a closed shell have received lot of attention in the last 20 years for satellites, due to their improved stiffness, buckling strength, multifunctional design, energy absorption. The geometrical freedom typical Additive Manufacturing allows lighter, stiffer, more effective be designed aerospace applications. Laser Powder Bed Fusion techn...

A new additive manufacturing technology for industrial mass production of footwear, apparel and accessories branded as “Haptic” will be introduced. Applying traditional non-digital screen printing technology for additive manufacturing, a totally new approach of footwear manufacturing was implemented successfully in 2015 at Huafeng Textile Group in China. Production was scaled up from zero to 50...

Additive Manufacturing (AM) processes, also known as 3D printing, enable geometrically complex parts to be produced layer by on the basis of three-dimensional (3D) data generated either scanning physical objects or using design software. Compared conventional manufacturing AM offers elimination production steps, allowing rapid and relatively easy prototyping from model designs, reproduction exi...

Ultrasonic-assisted wire–arc additive manufacturing (WAAM) can refine microstructures, enhancing performance and improving stress concentration anisotropy. It has important application prospects in aerospace, weaponry, energy, transportation, other frontier fields. However, the process parameters of ultrasonic treatment as an auxiliary technology WAAM still have impact on product indicators, su...

Additive manufacturing (AM) or “3D-printing,” which is another term often used to describe all additive manufacturing processes but is in fact just a subset of AM technologies, has received substantial and rapidly growing attention in recent years in both the popular press and in technical publications. Phrases like “make anything at any time,” “art to part,” and “complexity is free,” along wit...
