...Sergio Martín-Béjar; Fermin Bañón García; José Andrés Andrés López-Fernández; Carolina Bermudo Gamboa Purpose This study aims to analyze the influence of extrusion temperature, printing speed and layer thickness on dimensional accuracy, geometric deviations and surface roughness of Nylon 12 parts...

... on the mechanical properties of 3D-printed fabric yarns of three different materials, namely, polyethylene terephthalate glycol (PETG), nylon and thermoplastic polyurethane (TPU). Design/methodology/approach 2/1 Twill fabric samples with variations of extrusion temperatures and printing profiles are produced...

... embedded into both Onyx and nylon matrix were printed using Markforged-Two 3D printers. Specimens with different fibre orientations and fibre volume fractions (Vf) were printed. A drop-weight impact test was performed at energies of 2, 5, 8 and 10 J. Flexural testing was performed to evaluate the flexural...

...Javier Munguia; Kenny Dalgarno Purpose – The purpose of this paper was twofold: first, to determine if rotating bending could be used as an effective way of determining the fatigue behaviour of laser-sintered nylon, and second, to examine whether the fatigue behaviour of laser-sintered PA12...

...Thomas L. Starr; Timothy J. Gornet; John S. Usher Purpose The purpose of this paper is to measure the effect of process conditions on mechanical properties of laser‐sintered nylon 12 (Duraform^®) and to determine the range of conditions that provide consistent mechanical performance...
