What does 3D printing produce?

a paragraph describing an object

The text describes the steps involved in 3D printing. What happens after a 3D printer starts squirting out thin layers of a material like plastic or metal?

The layers build up and harden, becoming a physical object.

The layers soften and melt into a plastic for architects to use.

The person operating the printer must assemble the object.

The 3D printer shuts down for a year to rest and restart.

Read these sentences from the passage. “Can you imagine building a house in one day? A collaboration between a nonprofit organization and construction company in Texas is leading a revolution in homebuilding. It uses a gigantic 3D printer to build small homes by squirting layers of concrete to build floors and walls.” What can you conclude about 3D printers based on this information?

3D printers can make large objects more quickly than traditional methods.

3D printers are usually a little slower than traditional building methods.

Construction companies in Texas only use 3D printers.

3D-printed houses are usually much larger than normal houses.

The author says that 3D printers are being used to ice cakes and make plant-based burgers and steaks. What does this tell you about the kinds of materials used by 3D printers?

3D printers can print in many different materials, including food.

3D printers can only print very large objects in outdoor spaces.

3D printers are best at building things in concrete and metal.

3D printers can easily break if softer materials are used in them.

What is the main idea of this passage?

People are using 3D printing technology to build things from houses and medical devices to cakes and jewelry, saving time and money through the new technology.

Many chefs now use 3D printing technology to create vegan steaks and burgers, saving time that the chef would usually spend assembling and cooking the meat.

A 3D printer usually uses a 3D scanner or a computer program to sketch out what the printer will create in thin layers of materials like plastic or metal.

Architects have begun using 3D printers to make small, realistic models of houses they design to give clients a sense of what the finished home will look like.

Printing the Future

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like). Where does it come from? Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham. Where can I get some? There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.
