Which statement describes a limit of additive manufacturing?

• A. High cost of equipment and materials
• B. Unlimited material choices
• C. Very fast production
• D. No post-processing required

Answer: (A)

Cost is a major limit in additive manufacturing. The equipment itself tends to be expensive, especially industrial-grade printers, and the materials—such as specialized resins, polymers, or metal powders—often carry high ongoing costs. Those upfront and ongoing expenses can make the economics challenging, particularly for low-volume production, part customization, or educational settings where the same budget must cover multiple projects. This cost barrier helps explain why additive manufacturing isn’t automatically the cheapest option for every part, even though it offers benefits like design flexibility and rapid prototyping. The other statements don’t describe limits that apply as universally. Material choices aren’t unlimited because the printing technology and process impose constraints on what can be printed, in what form, and with what properties. Speed isn’t guaranteed to be very fast either; build times can be lengthy for complex or large parts, and post-processing adds time. Finally, post-processing is often required for cleaning, surface finishing, and achieving desired mechanical properties, so saying no post-processing is required isn’t accurate.
