Tanks of Gel Make 3-D Printing Fast and Easy

Time is a 3-D printer’s worst enemy. The machines work by piping out the printed object's material in thin layers, and have to wait for each layer to dry before adding the next one. If they didn't have to wait for the material to dry, a printer could construct items like furniture in a matter of minutes instead of hours. A team at MIT believes they found a way around this issue using giant tanks of gel.

As Co.Design reports, a new technique called Rapid Liquid Printing doesn’t require any layering. Instead, a needle injects the material (either liquified rubber, foam, or plastic) directly into the gel. The gel supports the hot liquid so the machine is able to move on with the rest of the design without waiting for the structure to harden.

MIT’s Self-Assembly Lab developed the technology after they were approached by the office furniture company Steelcase last year. Yuka Hiyoshi, a senior industrial designer for Steelcase, compared the method they landed on to “calligraphy or drawing” when speaking to Co.Design.

The Self Assembly Lab isn’t the first group to come up with a rapid 3-D printing process. The continuous liquid interface production (CLIP) method from Carbon3D uses oxygen and UV light to liquify and harden materials instantaneously. But while that technology is good for printing small, detailed objects in a few minutes, MIT’s printer is ideal printing larger items in the same time frame.

Rapid Liquid Printing works with any item that fits in a vat. Furniture for Steelcase, specifically tops for coffee tables, has been the first big experiment for the printers. Results have been promising, but the company doesn’t plan to integrate the technology into its commercial products just yet. Manufacturing car and plane parts is another possible application for the machine.

Stuck in a Never-Ending Group Chat? Here's How to Stop It

The more contacts on your phone, the more likely you will be periodically pulled into the dreaded group chat—a meandering, pestering chain of communication on apps like Facebook or WhatsApp that keeps your cell in a constant state of alert. While some group chats start out informative, they can quickly devolve in utter banality. (One warning sign: a funny nickname for the chat.) How can one free themselves from this chorus and get on with their lives?

David Nield at Gizmodo recently broke down the steps you can take to pull yourself free, though it depends on which chat app you’re using. If it’s WhatsApp, for example, you can go to Settings, Account, Privacy, Groups, and then set who can add you to a group chat. That way, only people in your inner circle can loop you in. If someone who isn't on your approved list adds you to a chat, you'll get a direct message inviting you to join, which you can accept or ignore. If you’re already in group chat hell, WhatsApp will allow you to mute notifications by tapping on the Menu button and selecting Mute Notifications.

Facebook Messenger doesn’t allow you to pre-emptively opt out, but you can exit existing group chats by tapping “i” inside the thread and selecting “Leave Group” in Android or tapping the chat thread and clicking “Leave Group” in iOS.

The same is true of Apple’s iMessenger—you can’t insulate yourself from chats. Once it starts, though, you can leave by tapping the top of the conversation, selecting “i,” and selecting either Hide Alerts (which mutes the chat) or Leave This Conversation. If people in the chat are using SMS, the messages will still come through, however. They have to be either muted or removed from your phone and life entirely.

Veterans Can Now Access Their Health Records Through Apple’s Health App

Apple’s iOS Health app is great for more than just checking how many steps you took during a lengthy walk in the park—it also stores health records from Johns Hopkins, Quest Diagnostics, Allscripts, and more than 400 other healthcare organizations.

Now, Fortune reports that the U.S. Department of Veterans Affairs (VA) has joined that list, making it easier than ever for military veterans who receive healthcare through the Veterans Health Administration to access all of their health records, including medications, immunizations, lab results, and other information. In the press release, Apple explains that the app will automatically update the records, so all veterans need to do is log into their providers’s patient portals through the Health app for a “single, integrated snapshot of their health profile whenever they want, quickly, and privately.”

Though the official announcement coincides nicely with Veterans Day on Monday, the change itself has been in the works for several months—the VA released the new feature to certain patients over the summer.

According to its website, the Veterans Health Administration is the largest integrated healthcare system in the country, servicing more than 9 million patients across 1255 healthcare facilities. With such an expansive network, any successful attempt to streamline processes and improve the flow of information—especially when it comes to sensitive, personal data—has the potential to be a major game-changer for veterans.

“Helping veterans gain a better understanding of their health is our chance to show our gratitude for their service,” Apple COO Jeff Williams said in the press release. “By working with the VA to offer Health Records on iPhone, we hope to help those who served have greater peace of mind that their healthcare is in good hands.”

Wondering what you can do to help veterans? Here are 11 honorable ideas.
