Characterization of 3D Printers and X-Ray Computerized Tomography

"For the highest printing quality, the 3D printing process flow requires multiple inputs. " Three teeth and one sandstone pebble with naturally deposited layers is also compared to printed sample results, while functional imaging analysis is performed using AI-based segmentation techniques to identify these 3D printers and determine three-dimensional surface roughness of three teeth and one sandstone pebble with naturally deposited layers. ProJet MJP offers the highest quality of printed samples with the least amount of surface roughness and very near to the true porosity value, according to the report.

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

"Modern two-photon-polymerization 3D printing technology enables the design of almost unlimited threedimensional structures for the manufacture of complex freeform optical surfaces. " During the manufacture process of monolithically manufactured complex freeform lens systems, we present a method to include repeatable measurements and the resulting shape correction. "This is an example of how such corrections could be used for the development of a low-profile multi-aperture large field of view objectives. ".

Metal 3d printing using high brightness blue laser systems

"Some industrially useful reflective metals absorb blue light much better than they absorb longer wavelengths. " The blue laser welding industry has soared adoption of high-quality, high-speed blue laser welding in emobility, energy storage, and consumer electronics, with the expectation that the same advantages to additive manufacturing/3d printing had existed. Here we share details from the first integration of the blue industrial laser into a scanner-based powder bed fusion device, the EOS M100 additive manufacturing system. The experiments were conducted with two completely different laser systems, the AO-650 and AI-200. The SS316L parts were printed twice as fast as the conventional IR laser by the blue laser, two years as the conventional IR laser. Full density on as-printed parts was obtained by 91 percent in blue industrial laser printing of copper test blocks. The EOS M100 IR laser could not be tested on the copper because the unit did not have sufficient power to melt the powder. ".

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

"We can simply produce sharp MNAs and good straightness with adjustable size in this paper, and adjustable size can be made with digital light processing 3D printing techniques, and PDMS molds can be produced by replicating MNAs through the soft imprinting process. " We also suggested a UV imprinting process to produce microneedle molds rapidly and abundantly by casting photosensitive resin in a PDMS mold to transfer the MNAs microstructure.

3D printing of surgical staples

"Our results showed that staples 3D printed with carbon fibre reinforced nylon 6 had a strength value of 37 % and an implantation-suitable ductility value of 26 u00b1 4%. " According to a load of 15 kg and 5 kg before and after immersion in simulated body fluid, respectively.

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

"Here, we show that advanced 3D printing technologies enable the production of polymeric microneedles with optimized geometries specifically intended to improve vaccine component coating. We compared traditional vaccination routes to 3D-printed microneedle delivery, improved cargo retention in the skin, activation of immune cells, and increased humoral and cellular immune responses compared to traditional vaccination routes.

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

"Fine measurable goals are aimed at increasing laser-driven proton acceleration for various applications. " To improve the energy conversion efficiency from laser to proton beam, we use a 3D-printed microwire arrayy system. The MWA's target is expected to produce over 1. 2 x 10 12 protons, extending to 25 MeV, corresponding to top-end energy conversion efficiency at 8. 7%. The MWA's spacing is found to be a predictor of proton energy/conversion-efficiency.

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

"3D printing, according to recent studies, could greatly aid in the manufacture of silica optical fibres of new material composition and structure designs that are otherwise impossible with current manufacturing techniques. " Then, the material processing for 3D digital light processing technology-based SOFs, is shown, including feedstock preparation, 3D printing, debinding, and sintering processes. Finally, we publish our latest findings on material processing, 3D printing, and, in particular, debinding-sintering processing, showing that a continuous debinding-sintering process, which includes a final stage of 2-h holding at 1240 u2218 C, is both cost-effective and cost-effective in achieving desired outcomes.
