If a product only can be made by 3D Printing, how could you use the plastic injection process to manufacture that especially in the mass production of big quantity? But if you can successfully solve this problem, you can absolutely low down the making cost. 3D Printing is only suitable for making the item with a complicated structure which normal manufacturing process can not reach. However it doesn’t mean we can not make these 2 technologies transformed freely. If you split the plastic product into several or many parts. Use plastic injection to make each part and design the clamping mechanism on each part to ensure the final assembly. Then you can make it. I have ever done that before for an Italian customer. Because our company-2fprototype is very good at it. So sometimes we need to imagine more then we can win more chances.
