The 3D-printing industry is accelerating its efforts to help fight the new coronavirus and the disease it causes, COVID-19.

On Tuesday, HP announced it’s working with those who bought its 3D printers to make medical face shields, hands-free door openers and an adjuster for face masks for medical staff who often must wear them for hours. It’s also testing “hospital-grade” face masks meeting the higher-end FFP3 (过滤式面罩) standard and parts for simple emergency ventilators (呼吸机) and it’s looking into nasal swabs to test for COVID-19 infection. HP also is offering free downloads of its 3D-printed medical equipment designs.

Carbon, whose 3D printers are used to make everything from bicycle seats to teeth straighteners, said it plans to send face shield designs to its network of customers who’ve bought its 3D printers. Carbon co-founder and Executive Chairman Joseph DeSimone said on Monday the company expects to send the designs by early Tuesday.

3D-printcr makers typically sell their products to others that actually do the 3D printing. One such customer, Ford, said Tuesday that it’s made 1,000 face shields and shipped them to Michigan hospitals, with plans to make 100,000 face shields a week. It is also working with 3M and General Electric on respirator masks and ventilator designs.

The effort is one of several to apply 3D-printing technology to the fight against coronavirus. 3D printing isn’t as fast at churning out products as conventional mass production methods. But 3D printers are flexible and able to make many different parts anywhere there’s a printer and raw materials like the plastic resins Carbon printers use.

Some 3D-printing efforts have focused on ventilators, which expected to be in short supply with a surge of COVID-19 patients suffering from respiratory (呼吸器官) problems. Also in short supply arc N95 masks that can be useful in reducing the likelihood a wearer will spread COVID-19 to others.

Carbon’s DeSimone is cautious about the enthusiasm, though, saying that regulatory approval is important and that 3D-printcr enthusiasts shouldn’t be making components not intended for close human contact that might release unhealthy gases.

For the business traveler who is all about efficiency: Check out these hotels that will get you in and out with a minimum of trouble. When you are pressed for time on a business trip, nothing can infuriate you more than a slow hotel check-in process. On your next trip, try these hotels that offer a speedier check-in process.

1.　 Yotel New York

The self-service kiosks at this high-tech New York hotel work just like the ones you’d see at an airport. There are just five-steps to register and obtain your card key. There is even a robotic luggage bellboy. You tap in the number of bags you are carrying and sizes, then wait for a robot arm to swing down and store your luggage in a locker (say, for a day trip). This also speeds up the check-in process if the first thing you need to do, like me, is head to a series of meetings.

2.　 Marriott Detroit Airport

Another option for business travelers in a hurry: Marriott is rolling out its mobile check-in app to 325 hotels this year, including the Marriott Detroit Airport hotel. (I’ve tested the app itself but not for a real visit quite yet.) Here is the basic idea: you download the iphone or Android app. The night before, you can “check-in” virtually. When you arrive, you get an alert that the room is ready and your key, which is already tied to your reservation, is waiting for you at the desk.

3.　 Hyatt Regency Minneapolis

I happened to stay at this hotel recently and liked how fast the kiosk check-in works. Like the Yotel, the kiosk asks you to insert your credit card, similar to an airport terminal. The whole process took about three minutes, when I left, I was equally impressed with the fast check-out. An agent meets you in the lobby with an ipad and asks for an email to use for a receipt. The big advantage: you never have to wait in line.

4.　 Radisson: LaCrosse

The Radisson is trying to make the kiosk process even faster, at a few select hotels like the Radisson Lacrosse in Wisconsin, you use a mobile app to register and then receive a barcode by email or text. When you get the kiosk, you scan the barcode to get your key without any other steps required. It’s super fast. You can find this new check-in system at the Radisson hotels in Salt Lake City, Seattle, and Phoenix as well.

1.What does the word “infuriate” in paragraph 2 most mean?

A. annoy　　 B. remind　　 C. amuse　　 D. impress

2.Which two hotels offer a mobile app for customers to check in?

A. Yotel New York and Marriott Detroit Airport.

B. Marriott Detroit Airport and Radisson: LaCrosse.

C. Marriott Detroit Airport. and Hyatt Regency Minneapolis.

D. Hyatt Regency Minneapolis and Radisson: LaCrosse.

3.Which hotel will send you a receipt by email?

A. Yotel New York.

B. Marriott Detroit Airport.

C. Radisson: LaCrosse.

D. Hyatt Regency Minneapolis.

4.Which of the following is TRUE according to the passage?

A. At Yotel New York, a robot will help you with all the check-in process.

B. With its check-in app, you may enter your room in Marriott without a key.

C. The barcode you receive from Radisson contributes to the fast check-in.

D. Hyatt Regency Minneapolis is close to an airport terminal.
