Klaas Rozema, founder and CEO of Dycomet, will now hold the position of Managing Director of Titomic Europe.

“The acquisition of Dycomet is an important step in Titomic’s strategic path to become a global company. We are delighted to welcome Dycomet on board and look forward to working with Klaas and his team on the many exciting opportunities this acquisition presents ”said Herbert Koeck, CEO of Titomic. “While Titomic focuses on high pressure applications, Dycomet serves the low and medium pressure market. Through our portfolio of complementary machines and products, the combined expertise now available to the company will further accelerate the growth of the company in new markets and provide existing customers with a broader product offering.

TriMech acquires the additive manufacturing group InterPRO

Speaking of acquisitions, TriMech, which provides CAD and engineering software, additive and subtractive manufacturing solutions, as well as training, consulting and staff associated with manufacturers and engineers in North America, is expanding its advanced manufacturing and rapid prototyping offering with the acquisition of InterPRO Additive. Manufacturing group. InterPRO has one of the largest deployments in North America of the new Stratasys Origin P3 system, and also offers in-house technologies including urethane and silicone molding and large format Multi Jet Fusion, FDM and SLA printing. With this acquisition, TriMech will add more than 70 3D printers to its existing line of more than 40 3D printers at its manufacturing and prototyping facilities in Ontario and Connecticut. Dan Straka, president of InterPRO, will become TriMech’s general manager of advanced manufacturing, and InterPRO will remain in its Connecticut plant as TriMech Advanced Manufacturing.

“The pace of change in additive manufacturing continues to accelerate. Advances in plastic and metal printing, speed and workflow, as well as high volume production are changing the demands and expectations of customers, ”said Marcel Matte, President and CEO of TriMech. “This acquisition brings together more experts and a broader technology offering so that we can be the best possible partner for manufacturers of all sizes.”

Braskem and Xenon Arc launch Amazon Store for PP filaments

Moving on to materials, Braskem, which is the largest polyolefin producer in the Americas, has partnered with Xenon arc to launch its first consumer store on Amazon to make polypropylene AM filaments more accessible to consumers. Xenon arc brings data-driven marketing and sales platform technologies to help Braskem better reach its small and medium-sized customers, and the e-commerce market is showcasing Braskem’s PP 3D printing filaments in diameters of 1.75mm and 2.85mm, which can be used for aftermarket design, rapid prototyping and custom product design, among other applications, due to impact resistance, durability and the chemical resistance of the material. The Amazon store will also sell Braskem’s award-winning carbon fiber reinforced PP filament.

“We are always looking for new ways to make our documents more accessible to consumers and small business clients,” said Jason vagnozzi, Braskem commercial director of additive manufacturing. “Through our partnership with Xenon arc, we have built a new e-commerce channel that overcomes some of the supply chain complexities that large commodity producers face when trying to reach consumers directly. Amazon will allow us to better serve small makerspaces, hobbyists and educational institutions that would benefit from our polypropylene innovations.

Hexagon Adds Additive Build Prep to ESPRIT CAM Software

Hexagon’s Manufacturing Intelligence division recently added additive construction preparation to its ESPRIT CAM software, which will provide digital tools to prepare components for powder bed fusion (PBF) 3D printing to streamline workflows. hybrid production and increase AM production volumes. According to the AMPOWER Additive Manufacturing Report, PBF accounts for 86% of the global additive manufacturing machine installation base, and with this addition, Hexagon’s ESPRIT CAM software now includes its Part-to workflow. -Build patented for printing and finishing operations for PBF, including construction preparation steps and programming tools for post-processing, providing this dedicated functionality in a single software that uses a parametric workflow data-driven. Customers can better optimize their AM part designs by using ESPRIT Additive PBF with other Hexagon products, such as Simufact Additive and MSC Apex Generative Design.

“Combining construction preparation in the CAM environment is the first step towards true computer-aided manufacturing using additive methods, enabling higher levels of automation and productivity. Our goal is to make the programmer’s life easier, thus making the workshop more productive and ready for the future to apply the best machines and processes available to the part in hand, ”explained Clement Girard, Product Manager for the additive manufacturing and artificial intelligence at Hexagon. .

Thermwood Adds Third Printing Orientation to LSAM Systems

In 2020, Thermwood Corp. introduced the option of vertical layer printing (VLP) in its LSAM (Large Scale Additive Manufacturing) systems, which can print vertical layers; it already offered HLP printing, or Horizontal Layer Printing. The company has now added a third printing orientation with its new Corner Layer Printing (ALP) option, which can print at an angle of 45 °. Because each of these orientations has its own advantages, offering all three on the same system, with the complete LSAM printhead, makes it an extremely flexible solution.

LSAM machines currently in service already have VLP capability, but for newer systems this has been replaced by a VLP / ALP option. If a customer has purchased a machine without VLP, this new VLP / ALP option can be easily added to most machines already in operation, and it is also supposed to be an inexpensive solution. LSAM systems, which are said to be the most widely used large-scale composite thermoplastic 3D printing systems in industrial production today, are available in a variety of configurations, including full print and cut and print only, in sizes ranging from 5 x 10 feet up to 15 x 60 feet.

Use of 3D printed models for the preparation of rhinoplasty surgery

Segmentation phase, multiplanar reconstructions on the axial (A), coronal (B) and sagittal (C) planes, in pink the mask imported post-segmentation of the MRI. (D), 3D models of bone tissue in white, cartilage structures in red (from MRI / CT co-registration), and soft tissues of the nasal pyramid in pink (transparent).

Finally, Italian researchers published a research paper on their use of CT scans, MRI data, and 3D printing to create pre-surgical models before rhinoplasty surgery and other surgical reconstructions of cartilage structures, which can be quite difficult. The goal was to come up with an imaging strategy to merge CT and MRI data to 3D print a model that, as the researchers wrote, is “true to the patient’s anatomy.” Ten patients who were candidates for rhinoplasty underwent CT scans and MRI to characterize their nasal structures for this study; bone and soft tissue segmentations took place in the CT scan and MRI captured the cartilage segmentations.

“Subsequently, a 3D model was produced in materials and colors reproducing the density of the three major structures (bone, soft tissue and cartilage), useful for pre-surgical evaluation,” the researchers wrote. “This study has shown that the optimization of a dedicated CT and MRI protocol has made it possible to reduce the dose of CT radiation by up to 60% compared to standard acquisitions with the same machine, and an MRI acquisition time. about 20%. Custom 3D models and pre-surgical planning reduced the average operative time by 20 minutes.
