    Ben benieuwd of de koers nog door de 18, ath, gaat in de komende dagen. Als dat gebeurt is er een goed perspectief. Wat jij Hirshi? Of kijk je nog steeds eerst naar de sector? En daarna naar de 200 daags gemiddelde koers etc.

    Siemens completes first successful installation of 3D printed part in Nuclear Power Plant

    It seems 3D printing is touching every single industry under the sun these days, including nuclear power plants. Regardless of how you feel about them, they do exist, and they are here to stay. It’s important to continue researching ways that additive manufacturing technology can benefit power plants, as the advancement of metal additive manufacturing can help produce components for these facilities in a more secure way.

    This summer, the US Department of Energy tapped GE to lead a $2 million additive manufacturing research project that’s relevant to advanced nuclear technology, and Russia’s nuclear energy corporation, Rosatom, is working to develop the first industrial metal 3D printer for the country’s nuclear industry.

    Today, global technology powerhouse Siemens announced that it has completed the first successful commercial installation, and continuing safe operation, of a 3D printed part inside a nuclear power plant.

    This milestone is a nuclear industry breakthrough: the nuclear sector obviously has incredibly exacting reliability and safety requirements, so the fact that a 3D printed part made it through these standards is a big accomplishment. The 3D printed replacement part was produced for a plant that’s been in operation for over thirty years in Slovenia, the Krško Nuclear Power Plant (NEK).

    In terms of safety, this power plant is ranked one of the highest of all European nuclear power plants by the European Nuclear Safety Regulators Group (ENSREG), an independent, expert advisory group. The Krško plant is of critical importance to the region, because it provides over 15% of Croatia’s power and more than 25% of Slovenia’s. This isn’t the first time Siemens has worked with the plant: the company has provided service and performed modifications on its non-nuclear side, including turbine and generator equipment, for over a decade.

    The part Siemens worked with is a metallic impeller, with a diameter of 108 mm, for a fire protection pump that operates in a constant rotation and provides pressure for the plant’s fire protection system. The original impeller is pretty old: it’s been in use since the plant was commissioned back in 1981. The manufacturer of the original impeller isn’t even in business anymore, which made this obsolete, non-OEM part the perfect additive manufacturing test subject. As the original design is “virtually impossible” to get, additively manufacturing it allows older plants, like NEK, to continue operating. A team of Siemens experts in Slovenia reverse-engineered the part, and created a “digital twin.”

    The Siemens state-of-the-art additive manufacturing facility in Finspång, Sweden, which opened a little over a year ago and marked the company’s first foray into metal additive manufacturing, 3D printed the impeller.

    In order to meet quality and safety assurance requirements, and make sure that the part would perform, the 3D printed impeller was put through extensive testing over several months, in collaboration with the operations team at the Krško plant. A CT scan and additional material testing took place at a separate, independent institution, and demonstrated that the 3D printed impeller’s material properties outmatched those of the original part.

    The Krško plant and Siemens are already looking for ways to advance the design of other parts that are hard to make with traditional manufacturing techniques, like lightweight structures that have improved cooling patterns. Discuss in the Siemens forum at 3DPB.com.

    DuBox to unveil first 3D printed concrete element in Abu Dhabi

    DuBox, a modular design, and off-site construction company, will be showcasing the UAE's first locally 3D printed concrete element from real-life construction objects, at a key industrial summit to be held in Abu Dhabi.

    A leading designer of complete single or multi-storey concrete buildings using modular methodologies, DuBox said it will sponsoring a pilot project at the inaugural Global Manufacturing and Industrialisation Summit (GMIS) which will be held at the Paris-Sorbonne Abu Dhabi, UAE, from March 27 to 30.

    A joint initiative by the UAE Ministry of Economy and the United Nations Industrial Development Organization (Unido), and co-hosted with the Abu Dhabi Department of Economic Development, the summit will be held under the patronage of Sheikh Mohamed bin Zayed Al Nahyan, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the UAE Armed Forces.

    It is the world’s first global gathering for the manufacturing community, bringing together leaders in business, government and civil society to shape a vision for the sector’s future.

    As a pioneer in the industrialisation of construction through modular, off-site construction solutions together with its global R&D (research and development) platform, DuBox will showcase its journey in innovation, bringing the building process from the site into a factory environment while rapidly prototyping new ideas and technologies.

    At GMIS, DuBox will also unveil as part of its R&D programme the UAE’s first locally 3D printed concrete element from real-life construction objects, an achievement made possible through its collaboration with the University of Eindhoven in the Netherlands and the engineering consultancy firm of Witteveen+Bos, said a senior official.

    Chebel Bsaibes, the founder, and chairman of DuBox, said: "Since 2009, DuBox has handed over 150,000 sq m of built-up environment introducing new technologies and techniques, disrupting the conventional process of the construction industry."

    Entire buildings are manufactured off-site in the DuBox factory, including all services and finishes, he stated.

    He said that "Modules are trucked or shipped pre-finished to job sites, where they are installed."

    3D printing a revolution at historic Sheffield
    Published on Mon, 10 Apr 2017

    The Star.co.uk reported that Sheffield following a GBP 6 million investment in a new Precision Foundry and equipment, including the largest 3D printer in the world. The new equipment can produce wax patterns of new complexity in one tenth of the time, for one tenth of the cost and with one tenth of the material as machining a shape from steel and aluminium.

    The new process involves dipping printed wax patterns in a ceramic slurry that is baked hard. It is heated a second time to melt away the wax the 'lost wax' method - before molten steel is poured into the empty ceramic mould.

    Once cooled, the mould is broken off to reveal a finished product which needs no 'fettling", grinding to achieve a perfect finish.

    NASA develops 3D-printed metal fabrics for use in space

    Indian Express reported that NASA scientists have developed 3D-printed metal fabrics that could be used for astronaut spacesuits or as shields and insulation for spacecraft. The foldable fabric which can change shape quickly could be useful for large antennas and other deployable devices as well. Another potential use might be for an icy moon like Jupiter’s Europa, where these fabrics could insulate the spacecraft, researchers said.At the same time, this flexible material could fold over uneven terrain, creating “feet” that would not melt the ice under them.

    The prototypes look like chain mail, with small silver squares strung together. These fabrics were not sewn by hand; instead, they were made using a technique called additive manufacturing, otherwise known as 3D printing. Unlike traditional manufacturing techniques, in which parts are welded together, additive manufacturing deposits material in layers to build up the desired object. This reduces the cost and increases the ability to create unique materials.

    Mr Raul Polit-Casillas from NASA.Fabricating spacecraft designs said that “We call it ‘4D printing’ because we can print both the geometry and the function of these materials.”

    Mr Andrew Shapiro-Scharlotta of NASA’s Jet Propulsion Laboratory said that multiple functions to a material at different stages of development could make the whole process cheaper. It could also open the door to new designs.

    The space fabrics have four essential functions: reflectivity, passive heat management, foldability and tensile strength. One side of the fabric reflects light, while the other absorbs it, acting as a means of thermal control. It can fold in many different ways and adapt to shapes while still being able to sustain the force of pulling on it.The team not only wants to try out these fabrics in space someday, they want to be able to manufacture them in space, too.

    In future, astronauts might be able to print materials as they need – and even recycle old materials, breaking them down and reusing them, said Polit-Casillas. Conservation is critical when you are trapped in space with just the resources you take with you, he said.

    Gisteren is Materialise over de €10 gegaan, dat is dit jaar al een rendement van 38%. Na de kwartaalresulaten een plukje bijgekocht vooral omdat ze nauwelijks meer gesubsideerd onderzoek doen en wel goede resultaten behaalden. Klein maar fijn en wie weet groeien ze echt door. Onlangs hebben ze nog een deal met Siemens gesloten. De prijs is mogelijk zo hoog omdat het een overnamekandidaat is maar gezien hun rol lijkt de sector beter af met Materilise als onafhankelijk speler.

    Materialise was bij mij even "out of picture",maar je hebt gelijk de potentie is groot en alle mega-investeringen moeten nu wel hun vruchten gaan afleveren.
