Question

Quizplus · Accepted Answer

Additive manufacturing, also known as 3D printing, builds products by adding material layer upon layer. CAM (computer-aided manufacturing) involves using software to control machines to manufacture products, but it does not necessarily involve layer-by-layer buildup. STEP (standard for the exchange of product model data) is a file format used for sharing 3D product data, but it is not a technology for building products. Replicator and virtual reality are concepts from science fiction and not currently available technologies for building products.
