Design for Additive Manufacturing (DfAM) is often touted as a "limitless" frontier. For mechanical design engineers transitioning from traditional subtractive manufacturing or injection molding, the freedom to create complex lattices and internal channels feels like a superpower. However, industrial 3D printing: specifically powder bed fusion technologies like Multi Jet Fusion (MJF) and Selective Laser Sintering (SLS): comes with its own set of rigid physical constraints.
