Characterization of 3D Printers and X-Ray Computerized Tomography

"The 3D printing process flow requires multiple inputs for the highest printing quality. " Functional Imaging analysis is also performed using AI-based segmentation tools to characterize these 3D printers and find the three-dimensional surface roughness of three teeth and one sandstone pebble with naturally deposited layers is also compared to printed sample measurements. ProJet MJP produces the highest quality of printed samples with the least amount of surface roughness and very close to the nominal porosity value, according to the results.

Topologically engineered 3D printed architectures with superior mechanical strength

"Lightweight fabrics help energy saving and reducing the amount of resources needed for manufacturing. " Researchers have invested considerable money in such products, which need new theories in both tailoring material microstructure and structural design, as well as structural design. Architectured materials, which take advantage of new engineering techniques, have recently emerged as a new way to produce custom mixes of desired macroscopic material responses. "Using computer aided design models, comprehensive parametric and bio-inspired architectures can be produced in a simple manufacturing process. " Beyond design, additive manufacturing has enabled the rapid fabrication of intricate geometrical and bio-inspired architectures.

Micro-3D-printed multi-aperture freeform ultra-wide-angle systems: production, characterization, and correction

"Modern two-photon-polymerization 3D printing technology allows for the production of nearly unlimited threedimensional structures for the production of complex freeform optical surfaces. " During the manufacturing process of monolithically produced complex freeform lens assemblies, we present a system to include repeatable measurements and consequent shape correction. An example of how such corrections can be used for the development of low-profile multi-aperture large field of view objectives is given. ".

Metal 3d printing using high brightness blue laser systems

"Most industrially important reflective metals absorb blue light much better than they absorb longer wavelengths. " The blue laser welding industry has increased adoption of high-quality, high-speed blue laser welding in emobility, energy storage, and consumer electronics applications, and it was expected that the blue laser would have similar benefits to additive manufacturing/3d printing. Here we present findings from the first integration of the blue industrial laser into a scanner-based powder bed fusion system, the EOS M100 additive manufacturing system. Test papers were printed using SS316L powder and pure copper powders. The SS316L parts were printed twice as well as the conventional IR laser by the blue laser. The full density of as-printed parts was obtained by 97% on copper test blocks in blue industrial laser printing. Since the EOS M100 IR laser did not have enough horsepower to melt the powder, it could not be tested on the copper. ".

Rapid fabrication of customizable microneedle molds using digital light processing 3D printing methods

"We can produce sharp MNAs and good straightness with adjustable width in this paper, and adjustable length can be manufactured by using digital light processing 3D printing techniques, and PDMS molds can be made by reproducing MNAs through the soft imprinting process. " a UV imprinting device to produce microneedle molds rapidly and inexpensively by casting photosensitive resin in a PDMS mold to transfer the MNAs microstructure," we said.

3D printing of surgical staples

"Our findings revealed that staples 3D printed with carbon fibre reinforced nylon 6 had a strength value of 37 % and a implantation-suitable ductility value of 26 %," says the presenter. According to a decrease in stiffness and strength of 40% and 70% after immersion in simulated body fluid for 60 weeks, respectively. ".

Transdermal vaccination via 3D-printed microneedles induces potent humoral and cellular immunity

"We find that advanced 3D printing technologies enable the manufacture of polymeric microneedles with controlled geometries intended to improve vaccine component coating. " We established that 3D-printed microneedle delivery improved skin longevity in the skin, activation of immune cells, and more potent humoral and cellular immune responses than traditional vaccination routes.

High efficiency laser-driven proton sources using 3D-printed micro-structure

"Innovating laser-driven proton acceleration for several applications, Fiine structured goals are promising to raise laser-driven proton acceleration for various applications. " To improve the energy conversion from laser to proton beam, we use a 3D-printed microwire arrayy system here. The MWA target achieves over 1. 2 u00d12 protons with cut-off energies rising to 25 MeV, representing top-end conversion efficiency at 8. 7%. The MWA's spacing determines proton energy/conversion-efficiency, according to the dependence of proton energy/conversion-efficiency on the spacing of the MWA. ".

Silica optical fibre fabrication via 3D printing technology: material processing and related issues

"Three-dimensional printing or additive manufacturing is revolutionizing manufacturing in several industries, including photonic materials. " 3D printing, according to new study, can greatly aid in the manufacture of silica optical fibres of new material composition and structure designs that are otherwise unavailable with current manufacturing techniques. Then, the material processing for 3D digital light processing technology-based SOFs that include feedstock preparation, 3D printing, debinding, and sintering processes, is presented," says Thomas Nek.
