Fiber orientation in film gated injection-molded rectangular plates was characterized using micro computed tomography. Polyamide 12 materials with 15, 30, and 50 wt% glass fibers were used in this study. For all three materials, the typical core-shell layer structure of fiber orientation was observe...

Two key issues in the manufacturing of microfluidic devices are to obtain low surface roughness, i.e. in the range of nanometers (to facilitate optical detection and controlled flow through microfluidic networks), and to achieve robust bonding. Here we report that a chemical polishing step, used for...

The field of additive manufacturing (AM) technology is advancing rapidly, with processes becoming more versatile, stable, accurate and economical at a steady pace. Advantages of AM compared to traditional manufacturing methods include the large geometrical freedom it offers to designers, combined wi...

Flat tensile specimens were produced from IN718 in SLM280 powder bed fusion machine. The specimens were arranged from flat to perpendicular positions on the build plate with 15° intervals. Support structures were used for all samples to facilitate slant printing and minimization of sample disto...
