When faced with a need for 100 unique parts or a single replacement component, traditional manufacturers often shrug and quote prohibitive tooling fees. Two modern strategies have risen to dominate this niche: Custom Additive Manufacturing Solutions and On-Demand Parts Production. In the first paragraph, it is vital to understand that while they overlap, each serves distinct scenarios. Custom Additive Manufacturing Solutions focus on tailoring every aspect of the part—material, geometry, surface finish—to a specific application. Conversely, On-Demand Parts Production emphasizes speed and inventory reduction, printing parts only when a customer orders them. The choice between them depends on your primary goal: optimization or availability.
