When transitioning from traditional 3D modeling to 3D printing, unique challenges arise due to physical material behavior and manufacturing process constraints, unlike 3D modeling’s focus on digital geometry. Key differences include: - **Material limitations**: Issues like shrinkage, warping, or poor layer adhesion can compromise part strength, a concern absent in purely digital models. - **Structural supports**: Overhanging designs require temporary supports, adding post-processing work not needed in 3D modeling. - **Speed vs. quality trade-offs**: Faster prints often reduce surface smoothness, a balance irrelevant in digital design.
To mitigate these, use slicing software to simulate printability and test small prototypes first, bridging digital design and physical output.
