UD engineers achieve 3D printing of continuous carbon fiber
As mentioned by the University of Delaware researchers, “A heater touches and moves along the carbon fibers to generate a dynamic temperature gradient, triggering the dispensed liquid polymer to infuse and cure in the carbon fiber structures.”
3D Printed 5G antenna
3D printing has become a popular method for producing antennas due to its ability to create complex shapes and structures quickly and inexpensively. To 3D print a 5G antenna, you would need to have a design for the antenna that is optimized for the 5G frequency range. This can be done using specialized software tools that simulate the antenna’s performance in various environments and conditions. Once you have the design, select the appropriate material for the 3D printing process. Several options are available, including plastics, metals, and composites, each with advantages and disadvantages. After selecting the material, you can use a 3D printer to create the antenna. Depending on the design’s complexity and the antenna’s size, this process can take anywhere from a few hours to several days. Once the antenna is printed, it must be tested to ensure it meets the required specifications for 5G performance. This can be done using specialized testing equipment that measures the antenna’s gain, efficiency, and radiation pattern.3D printing offers a fast and cost-effective way to produce customized 5G antennas, which will likely become more common as 5G technology continues to evolve.
According to Mark Mirotznik, professor of electrical engineering at the University of Delaware,” For technologies like wearables and things like that, it means we don’t have to have flat electronics anymore or flat antennas, it can be flexible. So for those applications, it’s really novel that you can actually print all of this stuff on a flexible membrane. It opens up new possibilities. 3D printing (specifically, NanoParticle Jetting technology offered by XJet) is the only manufacturing technique capable of meeting the production demands of a new kind of passive beam steering 5G antenna designed by his team.”
