ROSTI GROUP: YES YOU CAN

Contract manufacturing firm Rosti Group is using Ultimaker 3D Printing Technology to produce fixtures and assembly parts.

The company says it has adopted the Ultimaker S5 Pro Bundle to accelerate product development cycles and help clients get their products to market faster.

By incorporating the Ultimaker S5 Pro Bundle, which is supported by a wide materials range and has the ability to print fibre-reinforced components with the Print core CC, Rosti is replacing traditional prototyping methods where it can to save time, while also additively manufacturing fixtures and assembly components that match the strength and quality of those produced with subtractive methods. 

The results are the supply of new products to consumer markets and product samples to clients within 72 hours: “By removing traditional manufacturing methods from the development of assembly and production fixtures, the Ultimaker S5 Pro Bundle allows us to print high-strength and high-temperature materials at a fraction of the cost of previous methods and completed within a few days instead of weeks,” commented Scott Dickson, NPD Manager of Rosti Suzhou.

“Most certainly, Ultimaker is about fast first-time-right 3D prints of high visual and functional quality, but I get particularly excited when I learn how our technology serves as a transformative business solution for renowned companies like Rosti,” offered Ultimaker CEO Jürgen von Hollen. “The company recognised that it needed a rapid step change to remain competitive. Seeing that the flexibility and sustainable value derived from our 3D Printing Platform and eco-system has a strategic business impact in such a short turnaround time is what drives our teams as well our partners across the world.”

¿Could Chinese Cyber Army use 3D Printing to cheat The Pentagon?

“Biometrics are not an Achilles heel,” said Craig Williams, director of Cisco Talos Outreach. “Biometrics are something that makes it very, very easy to use. You don’t have to remember a password. You don’t have to enter a password, which makes it very fast and easy. You don’t have to carry anything around with you. And so I think for most users, it’s still perfectly fine.”

However, it’s possible to use 3D printing technology to create “fake fingerprints” suitable to cheat most fingerprint scanners from Apple, Microsoft and Samsung mobile products: Researchers with Cisco Talos created different threat models that use 3D printing technology, and then tested them on mobile devices (including the iPhone 8 and Samsung S10), laptops (including the Samsung Note 9, Lenovo Yoga and HP Pavilion X360) and smart devices (such as a smart padlock).

The fake fingerprints achieved an 80 percent success rate on average, where the sensors were bypassed at least once. Researchers did not have success in defeating biometrics systems in place on Microsoft Windows 10 devices (though they said that this does not mean they are not necessarily safer; just that this particular approach did not work).

Manufacturing of UAVs with MJF: Aldora

ALDORA is an UAV (Unmanned Aerial Vehicle) developed by a team from Universitat Politecnica de Catalunya (UPC) in Barcelona.

After a long period of construction feasibility problems, HP offered UPC engineers the opportunity to print the UAV, which meant a faster way to iterate the initial design.

Working together with HP and the Nacar design studio, UPC engineers managed to design a structure that could be printed in its entirety, using the 3D printing technology offered by HP.

Due to the modular design of the UAV, 3D printing offered the option to individually dimension and shape each joint, taking into account the needs of each one.

Regarding the challenges, the main challenge for the Aldora project was to make a large-scale UAV that was light, rigid and resistant. In addition, they needed to convert the maximum internal space of the UAV into a useful volume without jeopardizing its integrity.

Regarding the manufacturing technology and materials, initially wood and carbon fiber would be used since these materials are light and resistant. For the outer shape they thought about milling expanded polystyrene, but due to the small thickness of the profiles designed to make the flight more efficient, it was impossible to mill the material.

The only way to achieve the shape they were looking for, was making molds, what it was a solution as good as expensive. In addition, the number of hours they had to invest were not viable considering that for each iteration they had to create a new mold. and because of this they decided to discard this idea and start to think "out of the box", but more concretely in Additive Manufacturing.

Structural rigidity, precision for the aerodynamic surface and maneuverability in internal areas of difficult access were three maxims that the HP 3D Multi Jet Fusion technology offered to the Aldora team, and this technology made possible the creation of a remarkable UAV, in which 90% of the parts were been additively manufactured in a HP MJF 3D Printer.
