The Brightlands Materials Center, a Dutch R&D center, was established in 2015 by TNO and the province of Limburg, and is committed to improving3D printingPolymer material.Now, it will launch a self-sensing function3D printingComposite parts, which means they have the unique ability to perceive their own conditions, the material basically acts as a sensor.
On April 17, 2020, the company is using Anisoprint’s composite fiber extrusion additive manufacturing technology to manufacture composite parts with continuous fibers, so that they have this self-induction function.This will make3D printingThe parts can effectively monitor and support damage detection of important structures in the healthcare, construction and aerospace industries.
Nadezhda Kuzmenko, Marketing Director of Anisoprint, said: “This composite material can be manufactured by traditional technology, but through additive manufacturing, it can be done more easily and accurately. In addition, the present invention enables3D printingIt is more precise in itself. “
Anisotropically printed self-induced bending beam
Anisoprint said in a press release that polymer matrix composites with continuous carbon fibers have been proven to have this function because “continuous fibers have a measurable change in electrical resistance.” Typical self-induction materials are made by composite material manufacturing methods. These methods require special equipment and many steps to complete.3D printingMake it more effective.
Use continuous fiber3D printingThe carbon fiber can be oriented very accurately and positioned at a specific location inside the part. These fibers are an important part of the entire structure, which means that the material “sensor” is where it is needed. It is even possible to realize a series of sensors in the entire product by using many such optical fibers.
Anisoprint knows a lot about this, it invented a technology called anisoprinting, which uses its continuous carbon fiber3D printingTo design and manufacture the best composite structure.
Brightlands watched3D printingThe deformation of the miniature composite bridge, and a simple bending beam, to prove the self-induction capability of the composite material. Parts are in Anisoprint Composer A4 3D printingPrinted on the machine, the printer provides the freedom of carbon fiber layout and allows the user to choose any thermoplastic polymer material as the substrate. This allows the carbon fiber to extend out of the part and establish a connection with the monitoring electronics hardware so that it can properly act as a sensor.
Use this3D printingProducts made of the self-inductive composite material of the company may be incredibly important for the correct construction of bridges, the structural health monitoring of aircraft, and even diagnostic tools in healthcare.For example, if you use self-inductive materials to make3D printingThe prosthesis or orthosis can record important information about the patient’s movement patterns and pressure distribution, so that the doctor can provide a more ideal rehabilitation process.
