There are a few factors to consider when deciding whether to 3D print the final product or just the prototypes. The main factor is the quantity required. If you only need a few prototypes, it might be more cost effective to 3D print them. However, if you need to produce many copies of the final product, it might be more cost effective to use another manufacturing method.
Another factor to consider is the accuracy required. 3D printing is generally less accurate than other manufacturing methods, so if the final product needs to be very precise, it might not be suitable. However, 3D printing can be used to produce prototypes that are close enough to the final design to be useful for testing.
Finally, you need to consider the material requirements. Some materials can only be manufactured using certain methods, so you need to make sure that the 3D printing process is compatible with the materials you need to use.
