... Abstract Among the wide range of additive manufacturing — or “three-dimensional (3D) printing” — technologies, “material jetting” approaches are distinctively suited for multi-material fabrication. Because material jetting strategies, such as “PolyJet 3D printing”, harness inkjets that allow...

... Abstract In recent years, 3D printing, a highly promising additive manufacturing technique, has garnered significant attention as it allows the addition of fused materials layer by layer, to create intricate structures with ease and also offers the flexibility to incorporate multiple materials...

... the 3D printing process, coupled with a minimal rGO casting, accentuates surface roughness, thus increasing the effective surface area. After undergoing this surface engineering process, the sensor’s performance, as assessed by ferricyanide cyclic voltammetry (CV), displayed quasi-reversible...

... is as strong as that of those obtained by over-molding but about 35% higher than the 3D-printed interface. On the other hand, the hybrid ABS-TPU specimens with 5 wt.% CNTs exhibit electrical conductivity in the semi-conduction range, comparable with that of the over-molded specimens and about one order...

... Abstract The depowdering process in Binder Jetting Additive Manufacturing is indispensable for the integrity of 3D-printed objects, necessitating the removal of excess powder from their surfaces. However, this step poses a formidable challenge to the productivity of powder-based AM...
