AMSTERDAM AND THE MX3D SMART BRIDGE 3D PRINTING PROJECT

The project was funded by the Lloyd ‘Register Foundation, ABB, Air Liquide, ArcelorMittal, Autodesk, the AMS Institute, and Lenovo helped MX3D understand their vision. “A few years ago, we came up with the robotic metal 3D printers we had developed to print a functional life-size steel bridge,” explained Tim Geurtjens, co-founder of MX3D. The bridge design was created by mistreating generative design and topology improvement techniques, which, according to MX3D, allowed design freedom and ensured the reduction of vital material. “The distinctive design of the bridge would not be possible without 3D printing,” said Stijn Joosten, Arup’s structural engineer.

“Discovering the structural characteristics of 3D-printed steel is a critical step in the field of digital tool misuse. Written steel behaves terribly different compared to standard steel, which needed new analysis of basic materials with completely different slide rules. The ‘smart bridge’ supplies a network of sensing elements that can provide time-period knowledge flows in order for city authorities to explore the role of Network of Things systems within the engineering environment. For example, they will be able to analyze the anonymous behavior of crowds to better perceive the impact of business in Amsterdam’s Red Light District.

The project also addresses issues related to open knowledge, data ethics, and ownership of city analytics. The city of the national capital granted MX3D a biennial operating permit.

Sensitive sensor element network feeds digital twin

The digital twin will make it easier for engineers to experience the health of the bridge and control how it changes throughout its service life. The data from the sensors will also serve to “teach” the bridge what is happening on it, starting with the flexibility to count the number of people who cross it and how quickly they do it. “The expansion of our relationship with MX3D has given Autodesk a platform to test and improve our IoT digital twin technologies to assist MX3D in the development of its bridge, the world’s most sophisticated responsive structure in its design, creation and use.” said Alex Tessier, principal analyst for analytics at Autodesk. The mathematician, the U. Employing a personalized knowledge platform, the Turing supports researchers who need to access data from the detection elements to keep in their secure cloud.

Turing researchers can also develop novel and advanced digital twin models for the MX3D bridge prototypes and are currently applying these techniques to evolve the digital twin of the physical bridge because it is used. “When we combine 3D printing with digital twin technology, we can accelerate the infrastructure design process, ensuring that we create optimal and cost-effective structures in terms of environmental impact, field freedom and manufacturing costs.” freedom of the field and production costs, “said Mark Girolami, director of the data-centric engineering program at Turing.

MX3D noted that the support of the city of Amsterdam, stadsdeel Centrum, and its main technology workplace were essential to the success of the project. MX3D raised $ 2.7 million to launch its additive metal manufacturing system in April. Within the BRIDE project, funded by the government, the University of Twente, TU Delft, the Institute of Metropolitan Studies of the national capital and MX3D are learning the reactions of the social group to this type of construction.

Two-sided bridge

Building a 3D-printed metal bridge inevitably runs into obstacles and sudden changes, MX3D noted. MX3D mentioned that its engineers have continued to act on robots that will autonomously print the infrastructure in 3D. The company said this was worth its insight and confirmed that robots that print bridges without human intervention are no longer a fantasy.
