Electron beam melting (EBM) is a direct‐metal freeform fabrication technique in which 4 kW electron used to melt metal powder layer‐wise fashion. As this process relatively new, there have not yet been any independently published studies on the H13 steel microstructural properties. This paper describes EBM and presents results of analyses tool processed via EBM.
3D printing of biological architectures that mimic the structural and functional features in vivo tissues is great interest tissue engineering development transplantable organ constructs. Printable bio-inks are compatible with cellular activities play critical roles process bio-printing. Although a variety hydrogels have been used as for bio-printing, they inherit poor mechanical properties and/or lack essential protein components compromise their performance. Here, hybrid Matrigel-agarose...
Titanium aluminide (TiAl) is an intermetallic compound possessing excellent high-temperature performance while having significantly lower density than nickel-based superalloys. This paper presents preliminary results of experiments aimed at processing TiAl via the electron beam melting (EBM) process. Two routes are explored. The first uses prealloyed powder, whereas second explores controlled reaction synthesis. Issues such as parameters, vaporization alloying elements, microstructure, and...
The cells in conventional packaging foams have random size and orientation, the energy‐absorbing behaviour of these is determined by collective contribution different sizes cells. In contrast to nature stochastic foams, 3D printing technologies allow engineers design produce having engineered cellular structures. this study, structures based on classic Kelvin 1887 model were printed 30 × mm thermoplastic polyurethane cubes with a repeating 216 unit One hundred consecutive cyclic compression...
In this study, various sandwich panel structures with different reticulate lattice core geometries were designed and then fabricated in titanium via the electron beam melting (EBM) process. Bending tests performed on samples, mechanical properties such as modulus, bending strength, energy absorption evaluated. Different failure mechanisms observed, it was found that auxetic cores exhibited more homogeneous deflection compliance compared other structures. It also demonstrated of can be...
A solid silver-ligand complex, μ-oxolato-bis(ethylenediaminesilver(I)), was developed for formulating particle-free conductive metal–organic decomposition (MOD) inkjet inks. The complex comprises both a high molar silver content and solubility in compatible polar solvents. An aqueous ink formulation with 29.5 wt % printed onto glass, polyethylene terephthalate, polyimide substrates. new hybrid thermal-photonic curing approach resulting substantially improved electrical properties substrate...
We model and compare the biological financial constraints of four prescriptions that serve as alternatives to conventional clearcutting followed by planting in eastern western boreal mixedwood stands. These alternative for full or partial conifer stocking are (1) reliance on advance regeneration with without augmentation fill-planting; (2) understory scarification during a mast year; (3) direct seeding either aerially scarifier-seeder; (4) underplanting. Our main conclusions concerning...
Sustainability assessments and biomass inventories often neglect the operational challenges involved in harvesting of forest for bioenergy. Thus, concerns that increasing demands will lead to greater environmental impacts, particularly on soil productivity, need be considered from an operations perspective takes into consideration technical cost limitations recovery. We examine recovery potential harvest residue (slash) three sites located north Kapuskasing, Ontario. The are Northern...
A gold nanoparticle (AuNP) labeled CRISPR-Cas13a nucleic acid assay has been developed for sensitive solid-state nanopore sensing. Instead of directly detecting the translocation RNA through a nanopore, our system utilizes non-covalent conjugates AuNPs and targets. Upon CRISPR activation, are liberated from RNA, isolated, passed sensor. Detection can be observed as increasing ionic current in chip. Each AuNP that is detected enumerated an event, leading to quantitative molecular Leveraging...
Most adaptive slicing implementations assume a maximum allowable cusp height which applies to the entire part. Practically speaking, however, most parts do not have uniform requirements. Some faces are required be smooth while other relatively unimportant. With implementation, users must specify stringent However, with non‐uniform specifications, it is possible that further gains in efficiency can achieved. This paper presents an approach specifying First, procedure developed uses edge...
This work concerns the laser wire directed energy deposition (LW-DED) additive manufacturing process. The objectives were two-fold: (1) process mapping – demarcating states as a function of processing parameters; and (2) monitoring detecting anomalies (instabilities) using data acquired from an in-situ meltpool imaging sensor. LW-DED enables high-throughput, near-net shape manufacturing. Without rigorous parameter control, however, often introduces defects due to stochastic drifts. To...
Lead Zirconate Titanate ( PZT ) is a commonly used piezoelectric material due to its high response. We demonstrate new method of printing and sintering micro‐scale films with low substrate temperature increase. Self‐prepared ink was Aerosol‐Jet printed on stainless steel substrates. After drying for 2 h in vacuum at 200°C, the were divided into two groups. The first group traditionally sintered, using thermal process 1000°C 1 an Argon environment. second photonically sintered repetitive...
