3D printing is an absolutely wonderful process to create a product, develop it over time, and evolve it with flexibility. 3D printing is also absolutely right on the money and allows you to manufacture things a number of different ways. We reveal an important 3D print project that we have been working on, a Microphone Block, a real world project that we have done for our own business which has evolved over two years and now has reached a certain level of maturity. We delve into the evolution and the production of our project so you can learn great lessons and insights to help you along the way in achieving your goals with using 3D printing.
