B。原因:文章中明确提到“A special machine called a 3D printer uses a digital design to create a physical object. The principle of 3D printing is similar to building a tower with blocks. One layer is added on top of another until the object is complete.”所以 3D 打印机是一种特殊的机器,...
Generally speaking, what is a 3D printer? A. A device that can create two-dimensional objects. B. A device that can create three-dimensional objects by building them up layer by layer. C. A device that can only be used in the field of medicine. D. A device that is not very useful...
3D printing, also calledadditive manufacturing, is a family of processes that produces objects by adding material in layers that correspond to successive cross-sections of a 3D model. Plastics and metal alloys are the most commonly used materials for 3D printing, but it can work on nearly anythi...
Learn how to 3D print. 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
Application of 3D printers3D printers are used in many industries, like aerospace engineering, dentistry, archaeology, biotechnology, and information systems. For example, a 3D printer might be used in archaeology to physically reconstruct ancient artifacts that were damaged over time....

The 3D printer can make many things. What is the material that a 3D printer usually uses? A. Paper B. Wood C. Plastic D. Metal 相关知识点: 试题来源: 解析 C。解析:3D 打印机通常使用塑料作为打印材料,纸一般不是 3D 打印机常用材料,木头和金属相对较少使用。
Although the field of 3D printing has a lot of complexities, the theory behind the technology is elegantly simple. Instead of removing material from something larger to shape it—a method humans have used to create things for millennia—3D printing adds material to a manufacturing substrate, givin...
