Victrex to Develop PAEK Grades for 3D Printing Targeted for Aerospace Industry

 Victrex is leading a consortium of companies and institutions pursuing innovation in 3D printing (additive manufacturing or AM). As part of its key role, Victrex will develop new grades of high-performance polyaryletherketone (PAEK) polymer based on innovative chemical formulations that are specifically designed to work in additive manufacturing processes. Although utilized in some AM applications today, current PAEK materials were originally developed for use in injection molding or extrusion manufacturing process. 

The new grades are targeted in particular at the aerospace industry, which is the consortium’s main focus, but will also consider applications in other areas, notably medical. Possessing intellectual property covering the new polymers being developed, Victrex was awarded funding from the UK's agency for innovation, Innovate UK, to help drive the project forward. Members of the consortium are other industry leaders such as Airbus Group Innovations, EOS e-Manufacturing Solutions, University of Exeter, E3D-Online, HiETA Technologies, South West Metal Finishing, and Avon Valley Precision Engineering.
A key objective is the improvement of the recycle rate for powders used in the additive manufacturing technique, laser sintering. This would significantly reduce polymer wastage in this type of additive manufacturing process and reduce costs. The project will also address unpredictability of inter-layer adhesion and parts surface finish in filament-based printing.

"Everyone is now keenly aware that additive manufacturing has the potential to revolutionize industrial production, since it no longer involves the high tooling and set-up costs of traditional manufacturing," noted David Hummel, Chief Executive of Victrex. "It also allows the production of very complex shapes and geometries that cannot be made by conventional means. High value, lower-volume applications such as aircraft components are the type of application that could benefit the most, although there are other areas, including medical that may also benefit."

The project now being undertaken by the consortium was originally conceived during a conference on polymer-based additive manufacturing at the University of Exeter in 2014, where Victrex presented some early-stage results on a new polymer with significant potential for additive manufacturing. The University of Exeter had already acquired experience and contacts in PEEK polymer-based additive manufacturing and was able to help bring the consortium into existence.

In fact, Victrex´s PAEK polymer is already being utilized for 3D printed parts in both filament fusion and powder-based laser sintering, while the company actively pursues new solutions. Within the industry, the consortium is looking at the innovative use of new PAEK polymer grades for potentially revolutionary aerospace-focused AM techniques. 

"This innovative project is a great example of Victrex once again leading the way and demonstrating how we are seeking to further develop the opportunities for our polymers,” commented Hummel, “expanding the market for PAEK applications and differentiating our business. We are at the start of an exciting journey in the formulation of new grades that can efficiently and cost-effectively exploit all the advantages of additive manufacturing.” 

By 2018, the project hopes to have technology demonstrators that represent proof points and a way forward to realizing all the advantages of additive manufacturing – including reduced costs and a faster time-to-market for products that include parts too complex to be manufactured using traditional methods. "Although this consortium is a multi-year program, companies who see a value for the benefits of PEEK polymer combined with the value propositions for additive manufacturing should contact us now to discuss their ideas", emphasized Hummel.

Adwen and LM Wind Power partner to present the longest blade in the world

Adwen and LM Wind Power have partnered to take a large step forward towards lowering the cost of energy in offshore, putting their respective technology expertise together to present the longest blade in the world.

The huge component of 88.4 meters has been specifically designed for Adwen's AD 8-180 wind turbine model, with 8MW nominal capacity and 180 meter rotor diameter. The first of these huge blades has just been manufactured at LM Wind Power's factory in Lunderskov (Denmark) and will be transported to a facility in Aalborg in the following days, where it will commence rigorous testing in the framework of Adwen's extensive product validation plan.

The engineering teams of both companies have been working together for months to design and integrate a blade that represents an important step forward in the race to lower the Levelized Cost of Energy (LCoE). With the largest rotor in the industry (180 meters), the AD 8-180 has the highest annual energy production (AEP) of all wind turbines. 

The LM 88.4 P blade has been designed with manufacturability and reliability in mind, benefiting from the unique know-how of LM Wind Power, developing large blades for offshore application for the past 25 years and resulting in a 925 MW installed base. LM Wind Power's track record combined with Adwen's powerful turbine, technology and unique experience from operating 630 MW offshore wind farms has resulted in a state of the art rotor integration with innovative features, building on proven technologies.







The 88.4 meters length of the blades is the best compromise between swept area, energy production, and the weight as well as the loads transferred to the wind turbine. This combination provides the optimum balance of plant costs and contributes to one of the most competitive LCoE in the industry. In addition, the blade design has been conceived with scalability in mind to enable the further development of Adwen's 8 MW platform.

"When you are building the largest wind turbine in the world, almost everything you do is an unprecedented challenge. We are going where no one else has ever gone before, pushing all the known frontiers in the industry. Having developed and integrated together with LM Wind Power the first unit of the longest blade ever and being able to start testing is a key step forward in the development of our AD 8-180 and proves that Adwen is at the forefront of the industry", says Luis Álvarez, Adwen General Manager.

LM Wind Power's CEO, Marc de Jong adds: "The LM 88.4 P blade is an extraordinary example of industrialized innovation at record breaking scale. It is based on innovation building blocks, rooted in 35 years of real life experience, in the design, technology and manufacturing of ultra-long, reliable blades. This blade is a strong proof point of the shared ambition of Adwen and LM Wind Power to bring forward best in class and proven rotor solutions for offshore application, increasing Annual Energy output through efficient and reliable technology."

Fraunhofer & Stratasys Redefine Movie Industry with Advanced Plastic 3D Printing Solution

Stop-motion animation has a unique appeal. When employing the technique, twenty-four frames equal one second of animation. Each frame must be meticulously set up with puppets and props incrementally altered in small movements. An entire movie is compiled from the individual motionless scenes, captured by a digital camera. LAIKA, the US-based animation studio, has produced three Oscar®-nominated animated films: The Boxtrolls (2014), ParaNorman (2012) and Coraline (2009). Their use of 3D printing in animation garnered them a Scientific and Engineering award from the Academy of Motion Picture Arts and Science. The studio's fourth feature, Kubo and the Two Strings, will open in theaters this year.


In order to produce the puppets facial expressions, LAIKA designs, models, animates and paints the faces in the computer, then uses color 3D printers to produce tens of thousands of slightly different facial expressions. LAIKA pioneered this technique on its inaugural film Coraline and has continued to push the limits of 3D Printing technology on each subsequent film. On LAIKA’s fifth film they will be utilizing the most cutting edge color plastic printing hardware from Stratasys combined with the powerful universal print driver Cuttlefish from Fraunhofer IGD to help achieve accurate and repeatable color from face to face.

Cuttlefish makes it possible to work with many printing materials at the same time, to accurately replicate the geometry, colors and smooth color transitions of the original, and to simulate the printout on screen in advance. “Our first tests were fantastic”, says Academy Award winner and director of LAIKA’s rapid prototyping department, Brian McLean. “We have never seen such accurate and detailed color before in a plastic 3D print.”
