题目内容
【题目】As you enter university, you are likely to be confused by new demands and challenges. You need to decide for yourselves what you want to achieve when you graduate. It is important that you have appropriate and realistic expectations of a university education and know how far you can go towards achieving your personal and academic goals, so that you will have a sense of achievement at the end of your first year as well as when you graduate.
This website aims to be a quick one stop information hub to help you understand more about learning at HKU and make better use of HKU’s support services.
University Life is an adventure that—literally everyone here is a key player.
Your strategic moves at each stage have a direct impact on the outcomes of this adventure. The key to winning is mainly about how you manage your resources, especially your time. Most successful players engage themselves in activities that meet their needs and goals.

【题目】We see the world in three dimensions. Now, we can print in three dimensions, too, thanks to a manufacturing process: 3D printing.
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive (连续的) layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizon till (水平的) cross-section of the eventual object. Today’s 3D printers are being used to print everything from design models to jewelry, crafts, product parts, body parts, and even food.
3D printing starts with making a virtual design of the object you want to create. This virtual design is for instance a CAD (Computer Aided Design) file. This CAD file is created using a 3D modeling application or with a 3D scanner (to copy an existing object). A 3D scanner can make a 3D digital copy of an object.
You will have to prepare a 3D model before it is ready to be 3D printed. This is what they call slicing. Slicing is dividing a 3D model into hundreds or thousands of horizontal layers and needs to be done with software.
Sometimes a 3D model can be sliced from within a 3D modeling software application. It is also possible that you are forced to use a certain slicing tool for a certain 3D printer.
When the 3D model is sliced, you are ready to feed it to your 3D printer. This can be done via USB. SD or WiFi. It really depends on what brand and type 3D printer you have.
When a file is uploaded in a 3D printer, the object is ready to be 3D printed layer by layer. The 3D printer reads every slice (2D image) and creates a three dimensional object.
Before you pick up a 3D printer and experimenting in the 3D world, consider how big the objects you might want to create. If your goal is to print foot-long rulers, you’ll fall short of that goal if the printer you choose can only handle objects smaller 6 inches in height and width.
Another reality check is print speed. You’ll be able to knock out a day’s worth of chores (琐事) while the printer is running, with a typical 4-inch model requiring as many as 12 hours to print. As with ordinary printers, print speed also depends on how well it prints.
