Product Design & Research
No matter what engineers are designing, they all are trying to make their products better, faster and cheaper. With 3D printing, these goals can be achieved. The speed of product design could be increased from months to days. The product development cycle becomes more efficient because by 3D printing prototypes, product designers can get feedback in the early stages of product development.
Moreover, there is total freedom to create parts with complex geometry. With a 3D printer, you will have a real-life version of the product within hours even if the model is complex and functional. The form and function of the product can be checked in the early stages of the process. And if there is a negative feedback of the model (design), it can be redesigned and 3D printed till the design is acceptable. 3D printing is shrinking manufacturing lead times and creating more room for innovation.
