What is a design limitation that AM still imposes?

Additive Manufacturing (AM), often referred to as 3D printing, is a revolutionary technology that allows for the production of complex geometries and bespoke designs. However, one of the notable design limitations it imposes is related to wall thickness.

In AM processes, particularly in techniques such as selective laser sintering or fused deposition modeling, there are specific restrictions on how thin walls can be printed. This is due to the material's capability to support itself during the layering process. If the walls are too thin, they may not be able to hold their shape or may result in objects that are weak and prone to failure. These limitations can significantly influence the design of parts, especially in industrial applications where structural integrity is crucial.

Understanding these restrictions is vital for engineers and designers who aim to leverage AM technology, enabling them to optimize their designs while remaining within the boundaries of the manufacturing process capabilities.
