“…Wang et al provided a guideline of using melt flow index (MFI) to check the printability of the material in FFF. [143b] They found out that a minimum MFI value of 10 g (10 min) −1 at 2.16 kg is needed to have successful extrusion.…”

“…Rheology plays an important role during the coating of the new layer in SLA methodology. Typical range of viscosity is between 0.1 and 100 Pa s,[62b,143a,145] although viscosity as high as 500 Pa s has also been successfully coated. For bottom‐up SLA technique, the viscosity should not be higher than 0.5 Pa s, as resin would not have sufficient time to fill in the new layer gap, thus causing fabrication failure.…”

“…For bottom‐up SLA technique, the viscosity should not be higher than 0.5 Pa s, as resin would not have sufficient time to fill in the new layer gap, thus causing fabrication failure. [143a] Zero‐shear viscosity is the parameter of interest in the melt rheology of SLS material, as no shear flow is applied. [144a] Low zero‐shear viscosity is beneficial for coalescence of particles during sintering.…”

Additive manufacturing (AM) has brought about a revolution in the way we can manufacture complex products with customized features. AM has paved its way in the application areas ranging from aerospace, automotive, consumer to biomedical. AM of composites has attracted special attention due to its promise in improving, modifying, and diversifying the properties of generic materials through introducing reinforcements. This review provides a detailed landscape of fiber‐reinforced composites processed via AM techniques. Different AM processes, various material formulations, and strengths and drawbacks of AM methods are discussed. Emphasis is paid to AM techniques focusing on continuous fibers, as they hold the promise of becoming the next‐generation composite fabrication methodology. The article also tries to identify the potential of AM technology for fiber‐reinforced composites and delves into challenges facing the area.

“…The middle plate was formed with stereolithography resin using a stereolithography apparatus 3-D printer. 21 By cutting out part of the bottom plate, we formed four pressure-guiding orifices, each with a diameter of 2 mm, for the flow field. The middle plate has 16 guiding orifices running perpendicular to the cyclone cross-section, and the three plates are arranged in a rectangular shape with fixing holes for 11 bolts.…”

A planar cyclone is designed for visualizing bubbles in the cross‐section of a degassing hydrocyclone. The pressure distribution is studied through a series of experiments and Reynolds stress model simulations. The velocity distribution of the planar cyclone mostly exhibits the quasi‐forced vortex zone and boundary layer zone. The bubble dynamics are simulated using both Euler‐Euler and Euler‐Lagrange approaches, and the output is compared with the imaging results. The Euler‐Euler simulation provides more accurate predictions of the bubble trajectory. The histograms of residence time and traveling distance given by the Euler‐Lagrange approach exhibit a reasonably regular pattern. With higher values of the inlet Reynolds number, stronger forces acting on the bubbles lead to a decreased but more uniform residence time. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2689–2701, 2018
