Characterization of 3D Printers and X-Ray Computerized Tomography

"For the highest printing quality, the 3D printing process flow must have multiple inputs. " Functional imaging analysis is also performed using AI-based segmentation tools to characterize these 3D printers and determine their three-dimensional surface roughness of three teeth and one sandstone pebble with naturally deposited layers is also compared to printed sample measurements. ProJet MJP provides the highest quality of printed samples with the least amount of surface roughness and almost identical to the actual 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 methods enable the fabrication of almost infinite threedimensional structures for the production of complex freeform optical surfaces. " During the manufacturing process of monolithically manufactured complex freeform lens systems, we present a method to include repeatable measurements and the resulting shape correction. An example of the use of such corrections for the development of low-profile multi-aperture large field of view objectives is given. ".

Metal 3d printing using high brightness blue laser systems

"Many commercially vital reflective metals absorb blue light more efficiently than they absorb longer wavelengths. " The blue laser welding has been used by increasing adoption of high-quality, high-speed blue laser welding in emobility, energy storage, and consumer electronics, and consumer electronics applications, and it was predicted that the blue laser would have similar advantages to additive manufacturing/3d printing. Here are the first results from the first integration of the blue industrial laser into a scanner-based powder bed fusion system, the EOS M100 additive manufacturing system. The blue laser cut the SS316L parts twice as well as the conventional IR laser, enabling the production of the SS316L parts twice as well as the conventional IR laser. The full density of as-printed parts on blue industrial laser printing of copper test blocks was at 97%. The copper was not tested on the copper because it did not have enough electricity to melt the powder," the EOS M100 IR laser could not be tested on it.

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

"We can easily produce sharp MNAs and good straightness with adjustable width in this paper, and then PDMS molds can be made by reproducting MNAs using the soft imprinting process. " We also suggested a UV imprinting process to produce microneedle molds quickly and cost-effectively by pouring photosensitive resin in PDMS molds to transfer MNAs microstructure. ".

3D printing of surgical staples

"Our findings revealed that staples 3D printed using carbon fibre reinforced nylon 6 had a strength value of 37 %" and an implantation-suitable ductility value of 26 %" -- according to the company's reports. Following immersion in simulated body fluid, respectively, the carbon fibre nylon composite staples were able to withstand a load of 15 kg and 5 kg before and after immersion in simulated body fluid.

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

"We show you that advanced 3D printing techniques enable the manufacture of polymeric microneedles of controlled geometries intended to enhance vaccine component coatings. " We investigated that 3D-printed microneedle delivery improved skin durability, enhanced immune cell activation, and more potent humoral and cellular immune responses than traditional vaccination routes.

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

"In increasing laser-driven proton acceleration for various applications, fine structured goals are expected. " To increase the energy conversion efficiency from laser to proton beam, we use a 3D-printed microwire arrayy system here. The MWA target achieves over 1. 2 % cut-off energies extending to 25 MeV, which corresponds to the top-end of 8. 7% energy conversion efficiency under irradiation of high contrast femtosecond laser pulse. The MWA's spacing makes proton energy/conversion-efficiency dependent on proton generation/conversion-efficiency.

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 research, can greatly facilitate the manufacture of silica optical fibres of new material composition and structure designs, which is otherwise impossible with existing manufacturing techniques. Then, the material processing for 3D digital light processing technology-based SOFs, including feedstock preparation, 3D printing, debinding, and sintering processes, is shown. ".
