Mica-Embedded PEKK Extrusion 3D Printing
Arkema PEKK
A category of semi-crystalline thermoplastics referred to as polyaryletherketones (PAEKs) characteristic chemical resistance, energy, excessive temperature tolerance, and excessive glass transition temperatures, and can be utilized as a metallic substitute in a number of industries. Supplies on this class, like polyetheretherketone (PEEK) and polyetherketoneketone (PEKK), are sometimes used as AM feedstocks, and PEKK particularly options inflexible ketone teams that decrease its melting temperature and improve its glass transition temperature, which may cut back warping and make it simpler to course of in extrusion-based 3D printers. Nevertheless, PEKK will not be with out its challenges, and researchers from the Pacific Northwest Nationwide Laboratory (PNNL) revealed a examine on tips on how to enhance the properties of PEKK by embedding it with mica platelets as a filler to enhance thermal conductivity and mechanical properties. Sheet-like phyllosilicate supplies, micas have excessive side ratios, good electrical and mechanical properties, are protected when embedded into matrixes, and low-cost, and the crew predicted that mica fillers would enhance the properties of extrusion-based PEKK 3D printing, with out adversely effecting the fabric’s chemical reactivity or stability in excessive environments.
“Right here, we report the mixing of three grades of mica platelets into PEKK at 10% and 30% mass loadings to generate an array of filament feedstocks that have been used to print objects with a easy FFF machine. The consequences of mica coating chemistry on the compatibility with PEKK and ensuing properties are described,” the researchers wrote.
“The printed composites have been successfully chilly crystallized post-printing equally to unfilled PEKK leading to elevated dimensional stabilities. All micas, when used as fillers in high and low relative PEKK crystallinities, elevated the tensile modulus of elements in correlation to the loading.”
Markforged Hires Chief Advertising Officer
On to enterprise, as Markforged has accomplished its government management crew with the appointment of Andrew Hally as Chief Advertising Officer (CMO), efficient January 4th. Hally has 25 years of expertise in know-how advertising and marketing, most lately as CMO at digital asset administration firm Bynder, and on this newly created function, he’ll assist drive model consciousness and velocity progress of the Digital Forge, in addition to oversee the corporate’s advertising and marketing operations from technique positioning to demand era. Reporting on to the corporate’s CEO and President Shai Terem, Hally will work out of Markforged’s international headquarters in Watertown, endeavoring to align and enhance advertising and marketing efforts for the corporate’s progress plans and objectives.
“Probably the most fascinating years of my early profession mixed {hardware} and software program know-how breakthroughs to speed up 3D design and prototyping. As we speak, the advance of 3D printing into end-use elements guarantees to remodel manufacturing throughout industries, with advantages not just for engineers and companies but additionally for the atmosphere and society. I’m honored and excited to hitch the crew at Markforged to assist understand this necessary imaginative and prescient,” Hally stated.
Lithoz Dispatches First Cargo from New Web site
Second manufacturing facility combines tremendously elevated capability, environment friendly warehousing and a brand new stage of high quality administration
Ceramic 3D printing chief Lithoz GmbH, a spin-off of TU Wien, opened its second Vienna, Austria manufacturing website this summer time, which is the fourth location worldwide after its American and Chinese language bases and Vienna headquarters. Now, the corporate introduced that it has entered manufacturing on the new XL hub, and that it lately dispatched the primary buyer cargo from there as nicely. This new central warehouse has extra storage capability for uncooked supplies and scalable manufacturing, each of which assist supply a faster order turnaround for purchasers, and high quality management is top-notch because of a monitored manufacturing atmosphere and a top quality assurance laboratory. All of those options mix to make sure the brand new website can supply extra environment friendly warehousing and logistics, which is able to enable for higher buyer help around the globe.
“Throughout the planning and implementation of this new manufacturing website, we targeted on sustainability, scalability and reliability,” defined mission chief Dr. Daniel Bomze. “We’re prepared and very nicely ready for assembly the quick rising demand of our clients.”
Vallourec Makes use of WAAM 3D Printing to Make Lifting Plugs
French multinational manufacturing firm Vallourec used Wire Arc Additive Manufacturing ( WAAM) to make two lifting plugs for oil and fuel firm Weatherford. These plugs, usually produced from cast thick-wall bars, are safety-critical elements that act because the junction between pipes and the rig elevator, and are used on the floor of the oil rig so operators can safely transfer and deal with lengthy, heavy tubular merchandise. They often take a very long time to make, as they require non-standard materials with distinctive mechanical properties, along with personalized dimensions so all of the elements are suitable, as a result of lifting plugs join with current gear. Weatherford wanted a VAM® TTR HW Riser Lifting Plug able to 100T for a buyer off the Australian coast, and Vallourec turned to its WAAM robotic in Singapore, which was solely a six-hour flight from Weatherford’s buyer. This know-how, which mixes direct deposition 3D printing with laser sizzling wire welding or automated metallic inert fuel (MIG) welding, was quicker, extra reasonably priced, and will deal with the required non-standard diameters, and the surface diameter (OD) of the lifting plugs—delivered in below two months fairly three or 4—elevated by 15%.
“Because of WAAM, we have been in a position to manufacture a lifting plug in half the time of the standard course of with the identical mechanical properties and assembly the client’s particular OD necessities with no minimal order amount,” stated Jinwei Li, Asia Pacific Gross sales Supervisor at Vallourec. “This wouldn’t have been potential with conventional processes as we might have been restricted to the OD of the accessible stable bar or we might have needed to buy a brand new stable bar with a bigger OD additional extending the lead time.”
3D Printed Avant-Garde SCRY Lab Shuttle Sneakers
Lastly, an rising footwear model and laboratory based mostly in Beijing, referred to as SCRY Lab, is headed by 22-year-old Zixiong Wei, who enjoys utilizing 3D printing as a result of it permits for extra experimentation in making footwear, even when a prototype doesn’t work. Wei spoke with HYPEBEAST about his Digital Embryo philosophy, the conceptual design for its signature SCRY Lab Shuttle silhouette, and just a bit about 3D printing, although I want he’d stated extra. He defined that he first turned fascinated about sneakers in junior excessive, studying about every model’s historical past and design, and the way he was first impressed by Nike’s Wind sequence for the idea behind the SCRY model. About 70% of the drain grooves within the SCRY Shuttle have been designed so it might be 3D printed in full, and Wei stated that product improvement takes about two weeks, although launching a pair of footwear entails a number of advertising and marketing and gross sales plans, so the cycle for that’s about two months.
“Outdoors a big firm, it’s a massive problem and funding to make a brand new pair of footwear. Even so, I used to be decided to decrease the brink of shoe design and manufacturing, and established the SCRY model. SCRY has been exploring totally different future potentialities, fairly than pursuing lighter, quicker, and extra resilient ahead instructions within the conventional sense. Generally, it isn’t the inner issues that disrupt an business,” Wei stated.
“The idea of “Digital Embryo” is a framework know-how that goals to run by way of all the design and manufacturing technique of a pair of footwear with a totally digital course of, all whereas attaining the 3D printing mass manufacturing capability, thus guaranteeing scalability of digital footwear. It could actually additionally understand a seamless on-line and offline enterprise mannequin.
“For instance, I can produce a number of digital simulation idea footwear and let customers select and order footwear, after which I’ll print them. Moreover, the “Digital Embryo” because the underlying framework can obtain true modular customization. A shoe can have lots of of combos.”
