Influence of layer bonding on compressive strength of 3D printed structure: An experimental study

In this study, the effect of bonding layers on the material's compressive strength is investigated by altering the layer thickness and print speed. Since initial plastic deformation, layer thicknesses of 0. 05mm and 0. 15mm were found to be similar elastic characteristics, but the 0. 15mm layer can take additional load after initial plastic deformation. A layer thickness of 0. 3 mills has significantly reduced elastic zone load capacity, but the plastic zone's strain continues to rise.

3D-printed equipment to decouple (powder) X-ray diffraction sample preparation and measurement

An alternative storage system for sample preparation from single-crystal and powder X-ray diffraction measurements at home source diffractometers is described. A system is described for single crystals that allows the storage of preselected crystals at cryogenic and ambient temperatures. 3D printing manufactures biodegradable polylactic acid equipment that can be customized to individual needs.

A modern multidisciplinary approach to a large cervicothoracic chordoma using staged en bloc resection with intraoperative image-guided navigation and 3D-printed modeling: illustrative case

BACKGROUND Cervicothoracic junction chordomas are unusual primary spinal tumors that are optimally treated with en bloc resection. OBSERVATIONS MODERN technological advancements make en bloc resection more economically viable than ever before. LESSONS The authors explore the surgical planning and specific techniques that aided in the successful en bloc resection of this right-sided chordoma via image-guided parasagittal osteotomy during two stages. The integration of emerging visualization technologies into complex spinal column tumor diagnosis may be able to ensure optimal oncological care for patients with difficult primary tumors of the mobile spine.

Multi-Functional 3D-Printed Vat Photopolymerization Biomedical-Grade Resin Reinforced with Binary Nano Inclusions: The Effect of Cellulose Nanofibers and Antimicrobial Nanoparticle Agents

By the vat photopolymerization additive manufacturing process, multi-functional, three-dimensional printed objects were produced. Three specific spherical NPs, copper oxide NPs, and a commercial antimicrobial powder were all used for the resin's mechanical enhancement, although three different spherical NPs, copper oxide NPs, and a commercial antimicrobial powder endowed the antimicrobial powder. This research lays the first step toward novel, multi-functional materials for vat photopolymerization 3D printing biomedical applications, where mechanical reinforcement and antibacterial activity are often desired in the operational environment.

The Influence of Solar Sintering on Copper Heat Exchanger Parts with Controlled 3D-Printed Morphology

Heat transfer in solar furnaces is different in comparison to classical ones, and the effect of concentrated solar radiation on sintered parts of sintered parts must be investigated in detail to determine the feasibility of solar furnaces in manufacturing small workpieces, from a scientific standpoint. With a 5 minute hold time from the microhardness value and microstructure point of view, the best results were obtained at 930 °C with 5 min holding time from the microhardness value and microstructure point of view.

Manufacturing of a Magnetic Composite Flexible Filament and Optimization of a 3D Printed Wideband Electromagnetic Multilayer Absorber in X-Ku Frequency Bands

With the increase of electronic gadgets in our daily life, there is a demand for targeted wideband electromagnetic absorbers that could be used on any type of surface-like antennas for interference attenuation or military vehicles for stealth purposes. In the X-Ku frequency bands, a wideband extensible flat electromagnetic absorber suitable for additive manufacturing has been investigated. Hence, the introduction of dedicated materials has demonstrated the strong promise of additive technologies for the production of thin wideband flexible EM absorbers.
