Lightweight and strong structural materials attract much attention due to their strategic applications in sports, transportation, aerospace, biomedical industries. Nacre exhibits high strength toughness from the brick-and-mortar-like structure. Here, we present a route build nacre-inspired hierarchical structures with complex three-dimensional (3D) shapes by electrically assisted 3D printing. Graphene nanoplatelets (GNs) are aligned electric field (433 V/cm) during printing act as bricks...
Thermoelectric generators (TEGs) provide a unique solution for energy harvesting from waste heat, presenting potential green energy. However, traditional rigid and flexible TEGs cannot work on complex dynamic surfaces. Here, we report stretchable TEG (S-TEG) (over 50% stretchability of the entire device) that is geometrically suitable various surfaces heat sources. The S-TEG consists hot-pressed nanolayered p-(Sb2Te3) n-(Bi2Te3)-type thermoelectric couple arrays exploits wavy serpentine...
Bionic multifunctional structural materials that are lightweight, strong, and perceptible have shown great promise in sports, medicine, aerospace applications. However, smart monitoring devices with integrated mechanical protection piezoelectric induction limited. Herein, we report a strategy to grow the recyclable healable Rochelle salt crystals 3D-printed cuttlebone-inspired structures form new composite for reinforcement devices. In addition its remarkable performance, growth mechanisms,...
Flame-retardant and thermal management structures have attracted great attention due to the requirement of high-temperature exposure in industrial, aerospace, power fields, but development protective fire-retardant with complex shapes fit arbitrary surfaces is still challenging. Herein, we reported a rotation-blade casting-assisted 3D printing process fabricate nacre-inspired exceptional mechanical flame-retardant properties, related fundamental mechanisms are studied....
Traditionally, the fabrication of temporary teeth restorations must go through multiple processes such as moulding, curing and post finishing, which requires extensive expertise dentists. In addition, handmade are usually unable to precisely fit patient’s due limited formability material. To address problem, a three-dimensional (3D) printing technology named temperature controlled mask image projection based stereolithography (TCMIP-SL) is presented for dental materials in this paper, with...
Three-dimensional (3D) printing methods, such as vat photopolymerization (VPP) and direct-ink-writing (DIW) processes, are known for their high-resolution multimaterial capabilities, respectively. Here a novel hybrid 3D technique that combines the strengths of VPP DIW processes to achieve functional structures devices, is presented. The method involves dispensing liquid-like materials via syringes into photocurable matrix material subsequently using Galvano mirror-controlled laser beam...
Purpose This paper aims to present a multi-material additive manufacturing (AM) process with newly developed curing-on-demand method fabricate three-dimensional (3D) object multiple material compositions. Design/methodology/approach Unlike the deposition-on-demand printing method, proposed printheads use digital light processing (DLP) projector selectively cure thin layer of liquid photocurable resin and then clean residual uncured effectively using vacuuming post-curing device. Each...
Abstract For the bottom-up based stereolithography (SL) process, a separation process is required to detach newly cured layer from constrained surface in fabrication process. Excessive force will cause damage built layers and surface. Different coatings, platform motions including tilting sliding, utilization of oxygen-permeable films have been developed address separation-related problems. Among these approaches, vibration-assisted (VA) method reduce has limited study. The underlying...
This paper reported a method for designing monolithic acoustic holograms with consideration of both amplitude and phase modulation, which can be used multifocal point beam forming by single element ultrasonic transducer in the frequency megahertz range. Mask-image-projection-based stereolithography 3D printing technology was induced to manufacture complex hologram pixel resolution 25 μm. A nine foci pattern letter U field shown 2 MHz were designed validate proposed method. Both hydrophone...
