Many new product designs and innovations have been restricted by the limitations of plastic injection molding and other conventional manufacturing processes. After the design is completed, the part typically requires modifications in addition to prototyping and tooling, which are costly and cause delays.
Available for decades, traditional 3D printing allows engineers to design
more complex geometries. However, high-volume end-use part production has not been practical due to slow printing speeds and limited material selection. Additionally, most 3D-printed parts are built in layers that must adhere to one another during the printing process. Under specific thermal stress or part orientation, the layers of some geometries may separate, causing the part to fail.
