Track Code: 2017-GUND-67661 Tags 3D printing, Additive Manufacturing, implants, Materials and Manufacturing, polymers Background Printing of highly viscous materials is a challenge. The only available method uses very high pressure flow to push the material through the nozzle for biomedical implants such as teeth. Such systems are highly specialized and expensive and cannot be integrated with existing commercial systems. Technology Summary Researchers at Purdue University have developed a finely controlled approach to 3D printing of typical polymers and novel material systems that could not previously be printed. Printing of highly viscous materials is possible through a modified nozzle at high flow rates. It can print typical polymer based materials at lower temperatures, which reduces warping in the final parts. It can also be used with thick pastes that consist of mixtures, ceramics, and semi-solid metals, with higher resolution and faster print times. Advantages Reduced flow stress and friction Works with highly viscous materials High resolution printing at high speeds Includes precise on/off digital control Integrates into existing 3D printing systems Potential Applications 3D printing Additive manufacturing Stage of Development Prototype testing
