A. small items can be made in the corner of an office B. it is currently the preserve of hobbyists in academic and industrial niche C. additive manufacturing is too complicated to be popularized at present D. the blue print of 3D printing has to be designed three-dimensionally ...
相关知识点: 试题来源: 解析 B。解析:文章中提到 3D 打印通过层层构建物体,只使用必要数量的材料来减少浪费,所以 B 选项正确。A 选项错误,应该是使用更少的材料;C 选项错误,3D 打印可以定制化生产,不一定是大量生产;D 选项错误,3D 打印是可定制的。反馈 收藏 ...
Wireframe modeling:This is one of the easiest methods to make a 3D model from scratch. Here, you bend “wires” along the edges of an object to create a three-dimensional structure. These objects consist of points, arcs, lines, curves, and circles. Triangles are the basic elements of a ...
When designing a 3D model that you will print using a desktop 3D printer, you might want to consider building size limitations. Your 3D printer might not even be big enough to produce the prop or action figure you are designing. It would be great if you can split the model into several ...
How does 3D printing affect prototyping? A. It makes prototyping more time-consuming. B. It reduces costs and saves time for prototyping. C. It has no impact on prototyping. D. It makes prototyping more difficult. 相关知识点: 试题来源: ...
These printers are fast, producing the meniscus in about half an hour, one thin strand at a time.After printing, some bioinks will stiffen immediately; others need UV light or an additional chemical or physical process to stabilize...
根据文章第一段“They also want to figure out how to make 3D-printing faster and cheaper. Mr. Zerbe says that currently, 3D-printing a house with concrete costs more than building a house with wood.(他们还想弄清楚如何使3d打印更快、更便宜。Mr. Zerbe说,目前,用混凝土3D打印房屋的成本高于用...
Preparing the Model for 3D Printing Once the model has been imported into the slicer app, we can convert the .STL file into a 3D printable file. A 3D printable file contains all of the instructions needed to turn the .STL 3D model into a printed part by controlling the XYZ motors, extr...
How fast can 3D printing be? A. Very slow. B. As fast as traditional manufacturing. C. Very fast. D. Not mentioned. 相关知识点: 试题来源: 解析 C。解析:文中提到“Another advantage of 3D printing is that it can be very fast.”。
On the downside, straight cuts can be time-intensive when it comes to assembly, as you have to manually align each part and make sure they remain in the correct position until the adhesive fully bonds them. Step 2: Printing Your Model By default, the stereolithography (SLA) 3D printing pro...
