Ефикасност материјала	High – Uses only material needed for the part.	Low – Material waste from cutting away stock.	High – Minimal waste in molding processes.
Complexity of Design	Can create complex shapes and internal structures.	Limited by tool geometry and cutting paths.	Moderate – Complex shapes require expensive molds.
Брзина производње	Slower for large batches but fast for prototyping.	Fast for mass production of simple parts.	Extremely fast for large batches, slow setup for molds.
Cost of Equipment	Moderate – Lower entry costs for desktop printers.	High–CNC machines and tooling can be expensive.	High – Tooling and molds are costly.
Опције материјала	Ограничен, but growing (пластика, метали, керамика).	Broad – Metals, пластика, и композити.	Broad – Primarily plastics and metals.
Прилагођавање	High – Ideal for bespoke, ниска количина, Прилагођени делови.	Low–standardized parts.	Moderate – Limited to mold capabilities.
Scale of Production	Best for low-volume, сложене, and customized parts.	Ideal for high-volume, Високо прецизни делови.	Best for mass production of simple parts.
