FSAM | Sheet | Low equipment requirements, broadens alloy selection | Requires specialized fixtures; “hook-shaped” defects cause weak interlayer bonding | Large structural components (e.g., aerospace skins, ship hulls), large-sized plate or wall-shaped parts |
FSDAM | Rod | Good interlayer bonding, no filler material required | Raw material requires repeated clamping; unbound zones exist at boundaries | Fabrication of functionally graded materials |
AFSD | Rod/ sheet/chips | High material applicability, wide material selection | Complex tools and high equipment requirements; heavily reliant on specific machine tools | Aircraft fuselage panels with rib stiffeners, dissimilar metal joining, large annular aluminum alloy components |
AFED | Rod | Continuous additive capability, high deposition rate | High manufacturing/maintenance costs | Reuse of powder or recycled materials; manufacturing of small-sized, complex geometry parts |
| FSEAM | Wire/chips | Continuous additive capability, low downward force | Wire can be fed continuously; chips require remelting | Remanufacturing using powder or scrap materials |
FRAM | Wire/ sheet | Continuous additive capability, high material utilization, low downward force | Tools require customization | Large complex components; repair of vertical plate defects in high-rib panels |
