What does "digital inventory" refer to in additive manufacturing?

Digital inventory refers to the practice of storing 3D models in a digital format, which enables on-demand production in additive manufacturing. This concept leverages the capabilities of 3D printing by allowing manufacturers to keep a vast array of designs stored digitally rather than physically producing and storing each part. When there is a demand for a specific part, it can be rapidly accessed from the digital library and printed as needed.

This approach allows for increased flexibility and efficiency in manufacturing processes since it reduces the need for large physical inventories, minimizes storage costs, and enables rapid prototyping and customization. The ability to produce parts on demand directly from stored digital files aligns with the principles of lean manufacturing, where efficiency and minimal waste are prioritized.

In contrast, other options describe alternatives that do not encapsulate the essential concept of digital inventory in additive manufacturing. For example, storing physical parts reflects a traditional inventory system rather than the innovative digital approach of on-demand production. Managing physical inventory of materials focuses on raw materials rather than finished digital designs, and utilizing multiple printers for simultaneous use emphasizes production capability rather than the digital storage aspect that defines digital inventory.
