Abstract Plymetal is the term used here to describe a composite structure where more than one solid metals are joined or pressed to gain unique set of properties. Mostly flat plates are used, which are then bonded together to form sheets for further forming processes. In this work, a novel plymetal is designed to create a structure with alternating layers of metals both in radial and in axial directions. In the radial direction, the plymetal was conceived by having a cylinder surrounded by annular structure of alternate material. In the axial direction, the centre cylindrical material is changed, followed by annular structure of alternate material. Such a plymetal is realised by laser-assisted direct metal deposition additive manufacturing technology. Two different metal powders, AISI H13 ...

Abstract The sintering densification behavior and microstructural evolvement of W-Cu-Ni alloys (90 wt% W, 5 wt% Cu, 5 wt% Ni) were investigated via selective laser sintering (SLS). Through the analysis of the surface morphology and microstructure obtained by different laser sintering parameters, revealing that the sintering mechanism evolves from solid state sintering to liquid phase sintering depends on the laser input energy. The sintered density initially increases with the laser input energy then decreases; the poring and balling phenomenon cannot be eliminated drastically. The SLS of W-5Cu-5Ni (wt%) alloys is a complete process of molten liquid phase spreading and solidifying, which is determined by the intrinsic properties of W/Cu and the laser sintering parameters.

OR Lasertechnologie (Dieburg, Germany) has launched a direct metal deposition additive manufacturing technique that enables reliable protection of sensor elements by means of a hard alloy. This technique makes it possible to significantly extend sensor elements' lifetimes in, for example, pipelines of the oil and gas industry.Each day, about a million barrels of crude oil, or 160,000m3, pass through a pipeline with a 1m diameter. Gas pipelines have an extremely high internal pressure of 100 bars, which can even reach 200 bars or more in offshore pipelines. Sensor elements used to monitor the flow suffer considerable wear as a result of corrosion and abrasion. This shortens their lifetimes and necessitates costly repairs, according to a statement.[Native Advertisement] The company's inno...

Publication date: 2016 Source:Procedia Engineering, Volume 150 Author(s): A.O. Cherniavsky, K.V. Gorbunov Technological parameters of selective laser melting determine the quality of the parts produced: porosity, residual stresses and so strength and plasticity. Numerical modeling can help understand this dependence. The modeling process must account for the fact that typical sizes of metal powder particles, used for selective laser melting, are comparable (near equal) to the diameter of the laser beam, so considering powder a continuum is not fully correct. It is shown that LS-DYNA finite element code has enough capability to model important features of the process – heat exchange, melting, contact interaction of the particles.

21. March 2016Rather than growing the entire part, the most effective use of additive manufacturing in many cases might be to grow the features onto a pre-existing blank. Part of what makes 3D printing fascinating is the seemingly magical way it produces a part. Starting as if from nothing—that is, starting with an empty machine or an undifferentiated bed of powder—the 3D printer or additive manufacturing machine proceeds without tooling and without a pattern to produce a solid and precisely detailed part. But this apparently magical effect is also, in many cases, inefficient. DM3D, an Auburn Hills, Michigan, maker of additive-manufactured production metal parts, has recently been making the case to some customers that there is a better way to additively build.

IMG - Discrete element simulation and experimental study of powder spreading process in additive manufacturing Publication date: Available online 9 November 2016 Source:Powder Technology Author(s): S. Haeri, Y. Wang, O. Ghita, J. Sun Powders used in additive manufacturing (AM) are spread into a compact layer of particles for sintering and this process is repeated layer by layer to form the final products. Spreading of rod-shaped particles in realistic AM settings is simulated using the discrete element method (DEM) to investigate the effects of particle shape and operating conditions on the bed quality, characterised by its surface roughness and solid volume fraction. It is discovered that larger particle aspect ratios, Ar, or higher spreader translational velocities result in a lower bed quality, i.e. a larger surface roughness and a smaller volume fraction. The surface roughness increases monoton...

Publication date: 2016 Source:Procedia CIRP, Volume 55 Author(s): Filippo Montevecchi, Giuseppe Venturini, Antonio Scippa, Gianni Campatelli Wire-Arc-Additive-Manufacturing (WAAM) is an Additive-Manufacturing (AM) process, allowing to produce metal components layer by layer by means of Gas-Metal-Arc-Welding (GMAW) technology. The advantages of this technology are the capability to create large parts with a higher deposition rate with respect to other AM technologies. Despite these great benefits, WAAM components are affected by severe distortions and residual stresses issues. Finite element process simulation provides an efficient way to study mitigation strategies for such issues. In this paper, a WAAM modelling strategy is proposed based on a novel heat source model that takes into accou...

The main hall of the GE Power plant in Greenville, South Carolina, has 65-foot-tall ceilings and is the length of several football fields. Here workers assemble heavy-duty gas turbines that are over 10 feet wide and 30 feet long, and which weigh up to 560,000 pounds. The largest of these turbines installed in a typical power plant can generate enough electricity for 500,000 U.S. homes. The complex job of assembling one turbine can take six weeks. In a corner of a nearby building, something far smaller is being made. One of hundreds of parts that go into a GE turbine, this one, called a flex tip, is no bigger than a can of soda.

Abstract We demonstrate how lasers can be applied for processing of sapphire. Due to its hardness, sapphire is difficult to process with mechanical tools and laser processing is the tool of choice. Based on this example, we show how novel laser material processes are being qualified and how different material qualities as well as process requirements regarding speed and accuracy define an applicative solution consisting of a combination of laser source and processing optics. Thus, one thing becomes particularly apparent: application know-how matters.

Highlights • The internal porosity of the powder feedstock is analysed. • X-ray tomography is introduced and used as non-destructive testing tool. • Quantification by image processing is applied. Abstract The deployment of additive manufacturing processes relies on part quality, specifically the absence of internal defects. Some of those defects have been associated with porosities in the powder feedstock. Since the level of porosity in the powder is generally very low, standard characterization techniques such as pycnometry and metallography are not suitable for quantification. However, the quantification of such micro sized porosity in metallic powders is crucial to better understand the potential source of internal defects in final components and for quality control purp...

Publication date: June 2016 Source:Engineering, Volume 2, Issue 2 Author(s): Anders Clausen, Niels Aage, Ole Sigmund Additive manufacturing (AM) permits the fabrication of functionally optimized components with high geometrical complexity. The opportunity of using porous infill as an integrated part of the manufacturing process is an example of a unique AM feature. Automated design methods are still incapable of fully exploiting this design freedom. In this work, we show how the so-called coating approach to topology optimization provides a means for designing infill-based components that possess a strongly improved buckling load and, as a result, improved structural stability. The suggested approach thereby addresses an important inadequacy of the standard minimum compliance topology opti...
