In total hip replacement surgery, short hip stems are presumed to reduce proximal stress shielding compared to traditional, long stems. Belgian researchers virtually implanted a commercially available calcar-guided short stem in a series of bones with deviating proximal geometry and performed finite element analyses. Given the large number of FEA models that had to be created, they used an automated methodology.
Patellofemoral joint complication is among the leading causes for the failure of primary total knee replacement. When the joint wears down and a total knee replacement surgery is recommended, one of the goals of the femoral component is to restore the trochlear groove in such a way that the patella follows its natural pathway during knee movement. Exactech performed a study to understand the native, healthy trochlear groove.
Sambon Precision & Electronics manufactures audio devices (earphones, headphones and speakers) and keypads for distribution in South Korea and oversea. When developing a new product, producing a prototype is a mandatory step in the development process. Sambon 3D prints the prototypes since it’s a fast and flexible method. Unfortunately, their 3D printing workflow wasn’t that smooth, and took up a lot of time for the data preparation team. Using Materialise Magics software, they were able to reduce file repair and platform preparation time significantly.
The new honeycomb structure in Materialise Magics22 allows companies to reduce material usage and printing time. As a beta tester of Materialise Magics22, Midwest Prototyping was one of the very first to try out the new feature.
Italian engineering company QualiCal saw an opportunity for innovation in lime production, and asked — could 3D printing help eliminate the single biggest cause of production downtime? It could and it has. Partnering with us, QualiCal developed a shaft level indicator that offers the potential for increased revenue of up to €1,400,000.
A growing number of patients has undergone both a total hip and a total knee replacement in the same leg. Researchers at the Biomechanics section of the University of Leuven wanted to understand whether the distance between the hip and knee implants — the ‘interprosthetic gap’ — would influence the femoral strength. This required a robust workflow for creating accurate finite element models. Using the Materialise Mimics Innovation Suite allowed the researchers to generate accurate surface and volume meshes based on medical image data.

In this case study, we investigate different part-support configurations of a patient-specific CMF implant, and determine which configuration is most suitable for the AM process. We do this by simulating deformations via inherent strain method and comparing the final deformations of the parts after support removal.
With over 9 million manufactured cars, buses, trucks and other vehicles, Tata Motors is leading the automotive industry in India. And by producing the majority of their output in their own country, they contribute to the ‘Make in India’ policy of the Indian government, launched to stimulate the country’s growth. As drivers of the Indian automotive landscape, they ventured to intensively apply 3D Printing as a new technology for their prototype development, using both Laser Sintering and Stereolithography machines. But how do they make sure they use these technologies in the most efficient way?
Sandwich panels are used in aeronautics and aerospace applications where high structural rigidity and low weight are required. Together with ATOS, a global leader in digital services, we have developed a lightweight titanium insert design for a sandwich panel. The insert design was specifically developed for production with Additive Manufacturing (AM) and allowed for a 66% weight reduction of the traditional insert design, which has a brick-like shape.
Driving pleasure, ergonomics and safety have always been important for the automotive industry. A rising new trend is smart mobility. This means applying innovation and modern technology to stimulate sustainable mobility. One of the goals of smart mobility is to cope with the negative effects of mobility such as traffic jams, pollution and traffic casualties.
A 43 year-old female runner suffered a displaced right femoral neck stress fracture that failed to heal with conservative treatment. She was treated at an outside hospital with percutaneous reduction and internal fixation.
