Hybrid Additive Manufacturing is best described as:

• A. A Process Which Includes Both Additive and Subtractive Methods in One Single Machine
• B. A Process That Adds Only Material in Layers
• C. A Process That Removes Material to Form a Part
• D. A Process That Uses Only Casting

Answer: (A)

Hybrid Additive Manufacturing blends additive and subtractive processes in a single machine. It builds parts by adding material in layers, like traditional 3D printing, and then uses a subtractive operation—such as milling or finishing—to trim or refine features, achieving tighter tolerances and smoother surfaces without moving the part to a separate machine. This integrated approach reduces post-processing time and handling, and enables finishing steps to be done in the same setup as building. It differs from purely additive methods that only add material, and from purely subtractive methods that only remove material. Casting describes a different production route altogether and is not about layering material in an AM system.
