The Problem: Complex composite parts with hollow interiors are difficult to manufacture. Complex composite structures, with hollow interiors, present unique manufacturing challenges where internal tooling, generally referred to as a cores or mandrel, is required to define the hollow internal features. Any part configuration that traps the mandrel inside the composite part, requires sacrificial tooling* or a more complex, collapsible or inflatable tool. *Sacrificial tooling – tooling that is only used once and must be [...]

There is a new game-changing thermoplastic material for the Stratasys FDM family called Nylon 12CF. The CF is an abbreviation for carbon filled. In this material, chopped carbon fibers are added to a proven FDM Nylon 12 polymer blend resulting in one of the strongest thermoplastics in the FDM material portfolio. Commercial production of carbon fiber began in the early 1960's, resulting from requirements for lighter weight parts and alternatives to metal. Its low thermal [...]

3D printing is a powerful technology with the potential to significantly change the practice of medicine. In the field of structural heart disease, this rapidly evolving technology can make a powerful impact. Limitations of two-dimensional imaging and added benefits of 3D printing Current conventional cardiac imaging modalities such as echocardiography (EKG), cardiac computed tomography (CT) or magnetic resonance imaging (MRI) primarily utilize two-dimensional (2D) methods that require significant expertise and experience to interpret. In the [...]

There is a new FDM material from Stratasys called Nylon 6. The Nylon family of polymers is one of the most widely used thermoplastics in manufacturing. Nylon 66 was created in 1935 by DuPont as a synthetic substitute for silk. This synthetic plastic could be stretched into a fiber that increased in strength as it was stretched. Notable uses were toothbrush bristles, women's stockings and parachutes for the U.S. military during WWII. Shortly afterward; engineering [...]
