Biomimetic architectures with Bouligand-type carbon nanotubes are fabricated by an electrically assisted 3D-printing method. The enhanced impact resistance is attributed to the energy dissipation rotating anisotropic layers. This approach used mimic collagen-fiber alignment in human meniscus create a reinforced artificial circumferentially and radially aligned nanotubes.
Most additive manufacturing (AM) processes are layer-based with three linear motions in the X, Y, and Z axes. However, there drawbacks associated such limited motions, e.g., nonconformal material properties, stair-stepping effect, limitations on building-around-inserts. Such will limit AM to be used more general applications. To enable 6-axis between a tool work piece, we investigated Stewart mechanism feasibility of developing low-cost 3D printer for multidirectional fused deposition...
Abstract Purpose To evaluate the accuracy of implant position using surgical guides fabricated by additive and subtractive techniques. Materials Methods A partially edentulous standardized mandibular model with different bone densities soft tissue was duplicated a diagnostic wax‐up performed for #30 area. reference radiographic guide cone beam computed tomography (CBCT) made in place. designed BlueSky Plan 4 software placed region. The STL file exported specimens (n = 15) were two...
Abstract Explosive developments in modern society bring huge fire loads. Previous detections at early stages are basically enabled by recognizing abnormal high‐temperatures, smoke particles, and flame light signals. However, the identification of these characteristic signals is generally accompanied an open or smoke, which makes it difficult to prevent further serious damage. Herein, a latent‐fire‐detecting strategy trace ammonia (NH 3 ) analysis based on nanohybrid Ti C 2 T x MXene/MoS...
Purpose Conventional machining methods for fabricating piezoelectric components such as ultrasound transducer arrays are time-consuming and limited to relatively simple geometries. The purpose of this paper is develop an additive manufacturing process based on the projection-based stereolithography fabrication functional devices including transducers. Design/methodology/approach To overcome challenges in viscous low-photosensitive piezocomposite slurry, authors developed a by integrating...
Ceramic stereolithography (CSL) is an additive manufacturing method for creating ceramic three-dimensional (3D) objects via the layer-by-layer photopolymerization of a suspension. A key challenge in CSL that support structures are required building overhanging to prevent part damage or deformation caused by gravity process-induced shears. Removing can result issues such as poor surface quality, high risk cracking, etc. To overcome this challenge, article presents new CSL-based fabrication...
Abstract Ceramic processing through the combined use of pressure and water offers a promising approach to achieve accelerated mass transport between ceramic particles at reduced temperatures, providing sustainable low‐temperature method for synthesis three‐dimensional printing. While previous studies have explored roles in fusion densification particles, underlying mechanisms, especially micro‐sized are still debated. This paper aims propose potential mechanism under effect water. Using...
Porous structure has wide application in industry due to some of its unique properties such as low density, thermal conductivity, high surface area, and efficient stress transmission. Both templating foaming agent methods have been used fabricate porous structures. However, these can only simple geometries. In recent years, many studies done use additive manufacturing (AM), e.g., stereolithography apparatus (SLA), the fabrication structure; however, porosity that be achieved is relatively...
Abstract The objective of the present study was to assess ability transduced rat bone marrow cells (RBMCs) that overexpress BMP‐2 loaded on a three‐dimensionally (3D) printed scaffold heal critical sized femoral defect. Tricalcium phosphate (TCP) scaffolds were 3D fit RBMCs with lentiviral (LV) vector expressing or GFP. rats randomized into following treatment groups: (1) RBMC/LV‐BMP‐2 + TCP, (2) RBMC/LV‐GFP (3) nontransduced (4) TCP alone. animals euthanized at 12 weeks and evaluated plain...
Piezoelectric arrays are widely used in non-destructive detecting, medical imaging and therapy. However, limited by traditional manufacturing methods, the array’s element is usually designed simple geometry such as a cube or rectangle, restricting potential applications of array. This work demonstrates an annular piezoelectric array consisting different concentric elements printed Mask-Image-Projection-based Stereolithography (MIP-SL) technology. The displays stable dielectric properties....
Abstract Cutaneous muscles drive the texture‐modulation behavior of cephalopods by protruding several millimeters out skin. Inspired cephalopods, a self‐morphing, stretchable smart skin containing embedded‐printed electrodes and actuated Twisted Spiral Artificial Muscles (TSAMs) is proposed. Electrothermally TSAMs are manufactured from inexpensive polymer fibers to mimic papillae cephalopods. These spirals can produce strains nearly 2000% using voltage only 0.02 V mm −1 . Stretchable...
Abstract Direct ink writing (DIW) process is a facile additive manufacturing technology to fabricate three-dimensional (3D) objects with various materials. Its versatility has attracted considerable interest in academia and industry recent years.

Semantic segmentation is a key technology for remote sensing image analysis widely used in land cover classification, natural disaster monitoring, and other fields. Unlike traditional segmentation, there are various targets images, with large feature difference between the targets. As result, more difficult, existing models retain low accuracy inaccurate edge when images. This paper proposes multi-attention-based semantic network images order to address these problems. Specifically, we...
