Additive manufacturing ( AM ) is a technology which has the potential not only to change way of conventional industrial processes, adding material instead subtracting, but also create entirely new production and business strategies. Since about three decades, technologies have been used fabricate prototypes or models mostly from polymeric metallic materials. Recently, products introduced into market that cannot be produced in another than additively. Ceramic materials are, however, easy...
Instead of foreseeing and preparing for all possible scenarios machine failures, accidents, other challenges arising in space missions, it appears logical to take advantage the flexibility additive manufacturing "in-space manufacturing" (ISM). Manned missions into rely on complicated equipment, their safe operation is a great challenge. Bearing mind absolute distance manned Moon Mars, supply spare parts repair replacement lost equipment via shipment from Earth would require too much time....
Most additive manufacturing ( AM ) techniques have in common that material is spread out as thin layers of a dried powder/granulate by roller or shaker system. These are mostly characterized low packing rate. On the other hand, appreciable densities can be reached use ceramic slurries. In this context, layer‐wise slurry deposition LSD has been developed. Specific features process reflected on basis already existing technologies. The microstructure laser‐sintered bodies will discussed, and...
Silicate bioceramics possess an excellent bioactivity; however, shaping them into complex geometries is still challenging. Therefore, this paper aims to present a new strategy for the of bioglass-ceramic with controlled geometry and properties starting from glass powder combined preceramic polymer, i.e. silicon resin, reactive fillers. The powder-based three-dimensional (3D)-printing wollastonite (CaSiO3)-based silicate bioceramic parts was demonstrated in work. resin plays dual role, as it...
The next steps for the expansion of human presence in solar system will be taken on Moon. However, due to low lunar gravity, suspended dust generated when rovers move across soil is a significant risk missions as it can affect systems exploration vehicles. One solution mitigate this problem construction roads and landing pads In addition, increase sustainability future missions, in-situ resource utilization (ISRU) techniques must developed. paper, use concentrated light paving Moon by...
This publication presents a solid freeform fabrication technique for ceramics in the alumina–silica system by layering binder‐free, high‐loaded ceramic slurries, followed selective laser sintering. The low melting silica phase and reaction sintering between alumina favor rapid prototyping of pure parts. On basis electroacoustic viscosity measurements, stable slurries from Al 2 O 3 /SiO powder mixtures water with high fluidity have been prepared layer deposition doctor blade like tape...
Abstract As humanity contemplates manned missions to Mars, strategies need be developed for the design and operation of hospitable environments safely work in space years. The supply spare parts repair replacement lost equipment will one key need, but in‐space manufacturing remains only option a timely supply. With high flexibility ability manufacture ready‐to‐use components directly from computer‐aided model, additive (AM) technologies appear extremely attractive. For metal parts,...
In additive manufacturing the powder bed based processes binder jetting and fusion are increasingly used also for production of ceramics. Final part properties depend to a high percentage on density. Therefore, aim is use best combination deposition method which leads packing particles. The influence flowability, process density discussed different including slurry-based ones reviewed. It turns out that reached by layer exceeds conventional deposition, however, drying depowdering extra steps...
Filigree structures can be manufactured via two-photon polymerization (2PP) operating in the regime of nonlinear light absorption. For first time, it is possible to apply this technique powder processing ceramic with a feature size range critical defect sizes responsible for brittle fracture and, thus, affecting toughness high-performance ceramics. In way, tailoring advanced properties achieved already shaping process. Traditionally, 2PP relies on transparent polymerizable resins, which are...
Introduction: Recently, efforts towards the development of patient-specific 3D printed scaffolds for bone tissue engineering from bioactive ceramics have continuously intensified. For reconstruction segmental defects after subtotal mandibulectomy a suitable engineered bioceramic graft needs to be endowed with homogenously distributed osteoblasts in order mimic advantageous features vascularized autologous fibula grafts, which represent standard care, contain osteogenic cells and are...
Dissociative chemisorption of H2O at the MgO(100)−water interface has been investigated both experimentally and theoretically. In particular, metastable impact electron spectroscopy (MIES) was used to image density occupied states on MgO(100)/Mo(100) surface for various degrees water exposure. After multilayer desorption, spectral features typical hydroxyls are present. To further study possibility dissociative water, a theoretical computational method called CECILIA (combined embedded...
