Additive Industries levert tweede printer

De eerste levering van een 3D-printmachine aan BMW blijkt geen toevalstreffer voor Additive Industries. Het Eindhovense bedrijf heeft een tweede metaalprinter - ter waarde van 2 miljoen euro - verkocht aan Kaak Groep. Dat bedrijf gebruikt het gevaarte (5 samengevoegde modules) voor het maken van onderdelen voor industriële bakkerijmachines. Kaak krijgt dankzij 3D-printen lichtere onderdelen en een snellere doorlooptijd bij ontwikkeling van nieuwe apparatuur. Het bedrijf test sinds vorig jaar met 4 andere bedrijven een proefversie van de printer, maar die bleek niet groot genoeg.

Thales Alenia Space takes 3D printed parts into orbit
Published on Fri, 19 May 2017

Over the past two years, satellites built by Thales Alenia Space have taken over 400 3D-printed metallic and polymer parts into orbit. With the recent launches of the Telkom 3S, SGDC and KOREASAT-7 satellites, plus satellites in the Iridium Next constellation, Thales Alenia Space says it has now sent into orbit 79 metal parts made by additive manufacturing (3D printing) and 350 polymer tube supports for chemical propulsion systems.

Out of the total of 79 parts, 47 have different designs, carrying out 13 different functions The tube supports are all identical, with 35 used on each of the ten satellites launched to date.

The company sent its first 3D-printed aluminium antenna support into orbit on the TurkmenAlem MonacoSat satellite in April 2015. Since then, all of the company’s telecommunications satellites feature lightweight 3D-printed antenna supports and reflector fittings.

In mid-January 2017, with the successful launch of the first Iridium NEXT satellites, Thales Alenia Space also sent into orbit satellites with propulsion system tube supports, the first flight application of thermoplastic additive manufacturing.

The next step for Thales Alenia Space will be the manufacture of larger and larger parts using this process, such as dual antenna supports for a new telecom satellite to be launched shortly. These parts measure 480 x 378 x 364 mm, a real challenge from the manufacturing standpoint.

The benefits of additive manufacturing are well known replacement of several parts with a single piece structure, leading to reductions in weight, along with cost savings. Additive manufacturing also means greater design freedom and the absence of tooling, which makes it the perfect technology for complex parts with curves, holes or cavities that are produced in small runs or on a one-off basis.

Thales Alenia Space generally focuses on metallic materials for this process, including aluminium and titanium. The most commonly used technique is laser beam melting with a bed of metallic powder.

Ford using 3D printer to manufacture some auto parts

Computers are now part of every aspect of our lives, from the news we receive to the vehicles we drive. Robotic welders, CNC (computer numerical control) milling machines and water jet cutters are all operated by computers to produce precise parts. Another way to take advantage of computers in manufacturing is to print the part.

In the past couple decades, parts printed by computer-controlled 3D printers has gone from fantasy to reality and it changes completely the way parts are made.

If you are not familiar with 3D Printing, the concept is very simple. The computer moves a print head back and forth over an X /Y axis and deposits material from the print head in the shape it wants.

The print head then moves up and deposits another layer of material and so on. The part appears to ‘grow’ as more layers are deposited. There are many variations on the printing process but the process just describes is sometimes called additive manufacturing.

It is usually done with plastic-based materials but can be done with other materials as well.

These simple printers have now become priced low enough that small companies and individuals can purchase them, but when it comes to producing big stuff, the machinery is much more complex.

Ford is the first automotive company to manufacture parts with the Stratasys Infinite Build 3D printer. Instead of building parts vertically, this large scale 3D printer builds layers horizontally, and the part cures in the heated chamber of the printer as the printer moves the part sideways.

This allows a part to be built that is as long as the building the printer is located in, although five metres is typically the longest part made.

3D printing at the current state of the technology will not replace other forms of manufacturing for most parts such as parts make in molds using the casting or forging process. Making parts by 3D printing is still a fairly slow process, where a part several feet long can take days to print.

However, 3D printing can manufacture parts not feasible with other methods. For example, a closed cell honeycomb part cannot be made in a mold but can be printed.

Not only can the part be made with a stronger design, it can also be lighter than a similar part made with other methods.

The Statasys Infinite Build 3D printer is capable of printing virtually any shape or part. Currently, 3D printed parts are being used on the assembly line as ergonomically-designed light weight tools for vehicle assembly.

They are also being used for a limited number of parts on Ford race vehicles but the most common current use is in vehicle design. An engineer can design a part such as an intake manifold, engine cover, or body component and have it manufactured in a matter of hours compared to the days or months and cost of building molds and casting a single part that may or may not ever see production.

The potential to build 3D printed parts for production vehicles is also being studied in Ford’s Research Centre in Dearborn. Large one-piece parts such as spoilers could be printed that would not only be lighter than existing parts but also have more complex shapes.

There are still obstacles to overcome with 3D printing. One of them is in how the part starts out in the printer.

It has to have a base to build upon, so there is extraneous material that may need to be removed before the part can be installed. The designer’s mind also needs to adapt. It is not enough to print the same part as you would build in other processes.

The part now needs to be designed differently, so there may be hollow sections, more complex shapes and perhaps different materials.

NanoSteel Introduces New Tool Steel Material for Powder Bed Fusion 3D Printing

by Clare Scott | Jun 19, 2017 | 3D Printing, 3D Printing Materials, Metal 3D Printing |

There’s been quite a bit of talk about steel in the 3D printing world lately. It’s not among the most common 3D printing materials yet, but its profile and potential are rising as companies and research institutions work to develop 3D printable versions of it. Just last week, the University of Pittsburgh received an award to begin developing steel 3D printing materials, particularly for the US Navy, which requires tough, durable materials that can hold up in a harsh sea environment. For those requirements, it’s hard to beat steel.

Tool steel is especially attractive for manufacturing; as its name suggests, it’s well-suited to making tools. It’s a particularly hard material with high tolerance to heat and abrasion, and is available in multiple grades to fit a variety of applications. It’s not surprising that it should be a highly desirable material for additive manufacturing, and there’s been a lot of demand for it, as Markforged CEO Greg Mark pointed out in a recent interview. Markforged will be developing tool steel materials for its Metal X 3D printer, and today NanoSteel announced that it is launching a new 3D printable tool steel material – the company’s first material for laser powder bed fusion after its successful development of a portfolio of materials for binder jet printing.

BLDRmetal L-40 is a case-hardening steel powder with high levels of hardness and ductility: it offers a case hardness of >70HRC and 10%+ core elongation. It’s easy to 3D print, making it an attractive alternative to more difficult-to-print tool steels such as H13, and according to NanoSteel, it outperforms M300 maraging steel. Designed for parts such as tools, dies, gears and bearings, BLDRmetal L-40 proved its capabilities when it was used to 3D print an 8-inch roll thread die set, which outperformed dies machined from D2 and M2 tool steels.

“We tried nearly every combination of material and conventional CNC machining process to create our dual-thread die sets, none of which could cut or grind the complicated dual-thread geometry,” said Mark Doll, President and CEO of Perfect Lock Bolt America Inc., the only manufacturer of dual-thread fasteners in North America that are resistant to self-loosening. “The NanoSteel solution delivers exactly what we are looking for, including excellent surface finish, flexibility, as well as strength and hardness for maximum die life. This is a welcomed technological innovation to the fastener industry. We have been pleased with our testing and are slated to start production this year.”
NanoSteel developed the new material through rapid iterative development at 3D printing service provider CFK GmbH.

“For us, the most important attributes of NanoSteel’s BLDRmetal™ L-40 are that it is easily implemented and creates crack-free high hardness components, which sets it apart from the many other tool steels we have tested,” said Dr-Ing. Christoph Over, CEO at CFK. “We are proud to be a preferred printing service provider for NanoSteel, which will allow us to continue to offer the most valuable products to our customers.”

Nanoparticles improve the strength of metallic alloys

Phys.org reported that superalloys are the wonder materials of metallurgy. By fine-tuning their composition, scientists can increase mechanical strength and improve resistance to corrosion and high-temperature shape changes. A*STAR researchers have shown that adding nanoparticles can make these materials even stronger. Inconel 625 is a superalloy that is 55 to 70% nickel with added chromium, molybdenum, iron, niobium-tantalum, plus trace amounts of numerous other metals. Inconel 625 is used in industrial marine applications because of its high corrosion-fatigue strength, tensile strength and resistance to chloride-ion stress-corrosion cracking.

Guijun Bi and co-workers from A*STAR's Singapore Institute of Manufacturing Technology and Institute of Materials Research and Engineering have reinforced Inconel 625 using titanium diboride nanoparticles. The improved superalloy is fabricated by a sophisticated technique known as laser-aided additive manufacturing.

Additive manufacturing is a class of fabrication methods that can create full-scale components by building them up one layer at a time. 3-D printing is one well-known example, but for metals, high-power lasers are typically needed. One such method is laser-aided additive manufacturing, a novel additive manufacturing technology which can be utilized for 3-D printing, surface modification and repair. It works by applying a laser beam as heat source, with the additive materials melted and deposited on to the surface layer by layer.

Bi explaned that "We show that adding nanoparticles to the metal base material is an effective way to tailor the material with significantly improved physical, thermal and mechanical properties, as well as excellent performance in terms of wear and corrosion resistance.”

Bi and the team mixed and ground together an Inconel 625 alloy powder and a titanium diboride powder with particles approximately 58 nanometers in size. Their additive manufacturing system comprised a powder nozzle on a six-axis robot along with the output from a high-power fiber laser. In this way, they were able to create one-millimeter thick layers of their material on a carbon steel substrate, which they built up into a rectangular block of 120 × 70 × 10 millimeters.

Analysis of their sample indicated that the titanium diboride nanoparticles mainly aggregated at boundaries between crystalline grains of the Inconel 625. Thus, the titanium diboride acted to reinforce the grain boundary. Mechanical testing of the sample demonstrated a significantly increased material strength, relatively high micro-hardness and good abrasive resistance.

Bi said that "We hope to develop this approach and explore new composite materials reinforced with nanoparticles for additive manufacturing.”
