Engineering company Royal Hasconindev DHV, polymer company DSM and Composites3D printingMachine companyCEAD cooperated to build a footbridge.CEAD, a company based in Delft, the Netherlands, is planning to integrate large-scale continuous optical fiber3D printingProcess commercialization. Their CFAM printing process can produce glass fiber or carbon fiber reinforced parts with a size of 4×2×1.5 meters.3D printingMachine designThe combination of degrees of freedom and these materials can provide a whole new way of constructing bridges and other building parts.

We have heard a lot about concrete printing in the past few years. Nowadays, large polymer printers have been used in molds for templates, and designers use printers to make large parts for tunnels and other structures. The CEAD and BAAM systems directly tested the structure. This time the pedestrian bridge is the first polymer3D printingbridge.
The combination of polymers and continuous fibers can produce lightweight and high-strength rigid structures. In some cases, such structures may be too fragile for bridge applications.In the past, many3D printingbuildingIt often fails when it comes into contact with components, especially things like freezing temperatures.
Royal Has Corning Business Development Manager Maurice Kardas said, “This cooperation will bring about a change in the way we think about the form and function of bridges. Compared with steel bridges, fiber-reinforced plastic bridges have a long life and lower total cost. Famous. Now we will use the new3D printingTechnology, Let us mass-produce fiber-reinforced plastic parts. By adding sensors to the bridge, we can become the “digital twins” of the bridge itself. These sensors can predict and optimize maintenance, ensure safety and extend the life of the bridge. “

Patric Duis, the head of the dsm division of the additive manufacturer, said, “The use of Arnite has significant advantages in bridge construction. We can use more flexible designs and use recyclable materials instead of traditional materials such as steel and concrete. We can manufacture A more environmentally friendly bridge. The previous design was challenging or even impossible… now it can be passed3D printingmachineDesign. “
Concrete is a huge pollutant, and seeing bridges made of recyclable materials or recyclable bridges will be a big development. Arnite is a hard PBT or PET material, which may be ideal especially in its PET form. However, the composite material itself is difficult to recycle.
The team must prove that these complex materials can actually be turned into useful recyclables. Researchers are facing the challenge of transforming complex conforming materials into recyclable materials. Nowadays, smart manufacturers have begun to use natural fibers to make composite materials, so as to realize the use of simple and sustainable composite materials.
A printing method of CEAD is suitable for the manufacture of molten particles, many large-scale3D printingThe technology is all based on particles, because this reduces the cost of parts, the use of polymer templates or structures is the ideal solution.
