Design and AM of the assembled products, having movable components

Additive manufacturing (AM) brings benefits in many industrial and medical applications. Sometimes it is useful to print the assembled product directly, rather than printing the individual components and assembling the product later using conventional methods.

The product can be assembled virtually, and the assembly is transferred to the AM machine software to be printed from a variety of available materials. The main advantage is a smaller number of components, which simplifies the structure of the product and saves assembly costs. However, there are also some disadvantages, as the printed product cannot be disassembled to service it or replace a defective component.

The paradigm of product design changes when the assembled product is printed directly. The spacing between moving components should be slightly larger than the grain size (e.g., in SLS - Selective Laser Sintering), but small enough to avoid clogging the joints. There will be fewer components, but their shape will be more complex. Nevertheless, AM costs do not increase significantly with component complexity. Some applications and case studies will be presented.
