3D Printing: From Spaceship Engines To Personalized Orthotics

Published

on

3D printing is going mainstream, and is the future of mass production, manufacturing anything from plastic to human organs to aircraft and spaceships.


We often look at digitization through the lens of how it will transform industries, economies and governments but lose sight of the impact it will have on people. The manufacturing process is no longer what it was. With exponential technologies, we’re moving from analogue to digital, and as digital becomes more dominant, what is now referred to as the Fourth Industrial Revolution is, in fact, a human revolution.

 “With this next industrial revolution, what we have is the opportunity to have something that involves data, involves a connectedness, and as a result of that, has profound implications in terms of a true ability to participate globally in the new economy, explains Scott Schiller, HP Inc.’s Global Head of Customer and Market Development.

“It comes down to personalization, localization, customization… and all of these things change the way we interact. There’s a lot of benefits, but they’re, in the end, they’re really a human benefit.”

A common misconception with 3D printing links to commercial, desktop printers that create once-off objects. The consumer 3D printing process is exciting, but tedious. Looking at next-generation manufacturing, mass industrial 3D printing is about building complex components or objects with internal structures that would be difficult, if not impossible, to replicate without a 3D printer.

NASA is testing the use of 3D-printed parts for its spaceship engines. Lonmin, a British producer of platinum group metals operating in South Africa, is using platinum powder to 3D print jewelry. Then, there’s Aeroswift, the largest 3D printer on the African continent, which can build 3D titanium aircraft parts with metal powder.

3D printing is going mainstream. It’s revolutionizing design, accelerating process-driven manufacturing across every industry and the accrued benefits are impacting society and the healthcare sector at scale.

Globally, and working closely with the World Economic Forum, HP has built a mutually-beneficial ecosystem around their Multi Jet Fusion technology and materials producers. From 3D-printed orthotics, which can be personalized to change the mechanics of how a person walks, to 3D-printed prosthetics, medical modeling is not new – it’s been around since the late 1980s (and if anything, the healthcare sector is where 3D printing first took off, thanks to the hearing aid market).

The key differentiator in digital manufacturing is mass production.

“Improved scanning technologies means the ability to get things exactly right, rather than roughly right, brings new possibilities.” says Schiller, adding that Invisalign Teeth Straightening uses a 3D-printed mould.

“The most important areas of improvement in 3D printing is not in the technology per se, but in the application of the technology to create meaningful impact,” explains Nkholise.

“I truly believe that as a continent, we need to adopt the impact of 3D printing in achieving economic growth, particularly in healthcare, where the benefits of the technology are proven to create a positive shift in how we provide quality healthcare for every person on the continent – through products such as costing made prosthesis, bio implants and surgical planning models.”

3D printing is an integral part of what iMed Tech does, and it is used for both the creation of physical products as well as the development of prototypes.

“There is a backlog of medical products, such as prosthesis, which we have a high need for, particularly in a continent like Africa where there is a high number of people damaging or losing valuable body features due to traumatic accidents or diseases such as diabetes, which contributes to a lot of people losing limbs from lower-limb amputation. We are a human population that is experiencing a high rise in non-communicable diseases, which are resulting in physical damage to body features – the rise in breast cancer is one such disease,” says Nkholise.

“iMed Tech has recently been involved in optimizing digital 3D design and printing through the online platform for creating 3D surgical planning models to help surgeons reduce time for planning for surgeries, achieve accuracy and better respond to patient care.”

Digital technologies are reshaping the manufacturing landscape. They allow people living in remote or under-developed areas to become an integral part of the new global digital manufacturing system.

Surge Of Smartphone Apps Promise Coronavirus Tracking, But Raise Privacy Concerns

Published

on

By

Topline: A pan-European team of researchers announced Wednesday their plan to release a smartphone app that would notify users if they’ve been exposed to someone infected with coronavirus, the latest example of tech-driven coronavirus solutions that have also raised concerns about user privacy.

  • A European project called Pan-European Privacy Preserving Proximity Tracing is working toward releasing a coronavirus tracing app in the next week that would use anonymous Bluetooth technology to track when a smartphone comes in close range with another, so if a user were to test positive for coronavirus those at risk of infection could be notified.
  • Contact tracing, or determining people who may have been exposed to someone with a virus, is an established aspect of pandemic control and was used effectively to tackle coronavirus in countries like China, Singapore and South Korea in the form of smartphone tracking.
  • University of Oxford researchers and the U.K. government are working on a similar project— but unlike other smartphone tracking systems, the British version in development would be based on voluntary participation and bet on citizens inputting their information out of a sense of civic duty.
  • The U.S. government is in talks with companies like Facebook FB and Google GOOGL and other tech companies about tracking if users are social distancing using large amounts of anonymous, aggregated location data— this information is less precise, and more likely to anticipate outbreaks rather than pinpoint individuals who have been exposed to the virus.
  • 1.5 million Israelis have voluntarily downloaded a mobile app that alerts users if they’ve come into contact with someone with coronavirus— but Prime Minister Benjamin Netanyahu has still ordered that potential coronavirus carriers have their phones monitored, a controversial move the government says is necessary, as the 17% of the population using the app is not enough to fight off the pandemic.  
  • Moscow , on a city-wide lockdown since Monday, announced Wednesday that a new phone app that will officials to track the movements of people diagnosed with coronavirus in the capital city would be launched on Thursday, saying the government will lend a smartphone to anyone unable to download the app.

Crucial quote: “We’re exploring ways that aggregated anonymized location information could help in the fight against [coronavirus]. One example could be helping health authorities determine the impact of social distancing, similar to the way we show popular restaurant times and traffic patterns in Google Maps ,” Google spokesman Johnny Luu told the The Washington Post. He made sure to note it “would not involve sharing data about any individual’s location, movement, or contacts.”

Key background: Private and public entities alike are looking for ways to fight off coronavirus as the pandemic continues. On Wednesday, there were more than 900,000 confirmed cases worldwide and nearly 50,000 deaths.Officials told The New York Times NYT that The National Health Service, Britain’s centralized national health system, is trusted by citizens— and paired with the strong data privacy laws in place, said they think people would agree to join the effort to share their private information to help trace infections. However, American tech firms are reported to still be skeptical about sharing substantial data with the U.S. government ever since Edward Snowden revealed the NSA was collecting information from the firms clandestinely. 

Surprising fact: The information tech companies have access to data that sheds light on Americans’ behavior in light of the coronavirus pandemic. According to a Facebook analysis, restaurant visits fell about 80% in Italy and 70% in Spain— while Americans only stopped eating out at a rate of 31%.

Apple Is Donating 9 Million Masks To Combat The Coronavirus

Published

on

By

Topline: Apple will donate 9 million N95 protective masks to combat the coronavirus, Vice President Mike Pence said on Tuesday, making Apple one of several California tech companies pitching in as hospitals across the country report a shortage of protective gear.

  • Pence thanked Apple for agreeing to donate 9 million N95 respirator masks to healthcare facilities across the country during a press briefing on Tuesday.
  • Pence’s remarks come after Apple CEO Tim Cook tweeted over the weekend the company was “working to help source supplies for healthcare providers fighting COVID-19” and “donating millions of masks for health professionals in the US and Europe,” but did not offer more specifics.
  • N95 respirators are masks that form a protective seal around a wearer’s mouth, filtering  out at least 95% of particles in the air, according to the Centers for Disease Control, which makes them necessary to protect healthcare workers from being exposed to the disease from patients.
  • Facebook has also said it is donating its stockpile of 720,000 masks purchased during the California wildfires last year, which degraded the air quality in the San Francisco Bay Area.
  • Apple did not immediately respond to a request for comment from Forbes asking if all of the donated masks were stockpiled because of the wildfires or if the company got them from somewhere else.

Chief critic: Teddy Schleifer, a reporter at Recode, wrote that health systems shouldn’t rely on the generosity of big tech companies to make up for the failures of the federal government. 

“But there is a risk in relying on corporate philanthropy—rather than the government—in solving this problem. For starters, it depends on the voluntary generosity of these companies to deal with an unprecedented emergency, an altruism that could vanish at any time,” he wrote.

Crucial quote: “And I spoke today, and the president spoke last week, with Tim Cook of Apple. And at this moment in time Apple went to their store houses and is donating 9 million N95 masks to healthcare facilities all across the country and to the national stockpile,” Pence said.

Key background: Apple is one of several California tech companies to give away N95 masks. In addition to Facebook, Salesforce, Tesla and IBM have also announced mask donations.

News peg: Doctors and nurses are sounding the alarm that they don’t have enough masks to protect healthcare workers. Not only does inadequate protective gear put important frontline health workers at risk, public health experts say, any situation endangering medical personnel may only further depletes the U.S. health system which already doesn’t have enough capacity to handle a surge in cases. State officials in New York and Illinois have criticized President Donald Trump for not stepping in to force companies to manufacture masks or allocate masks from private companies to ensure that states don’t outbid each other for the same supplies.

Video Games Are Being Played At Record Levels As The Coronavirus Keeps People Indoors

Published

on

By

Topline: With school closures, mandatory work-from-home policies and lockdowns taking place in the U.S. as a result of the Covid-19 coronavirus pandemic, gaming has seen higher engagement, especially over this past weekend.

  • Steam, the most popular digital PC gaming marketplace, reached new heights Sunday, drawing a record 20,313,451 concurrent users to the 16-year-old service, according to third-party database SteamDB.
  • Counter-Strike: Global Offensive, released by Steam-owner Valve in 2012, seems to be the top beneficiary of the increased engagement, breaking it’s all-time peak on Sunday with 1,023,2290 concurrent players, topping its previous peak last month by a million, which itself beat the record set in April 2016.
  • Like other esports, CS:GO has had to cancel events due to the virus, particularly the Intel Extreme Masters in Katowice earlier this month, though its peak viewership reached over a million, making it one of the most watched tournaments in the esports’ history.
  • Activision Blizzard’s new free-to-play battle royale spinoff Call of Duty: Warzone, launched March 10 on PC, Xbox One and PlayStation 4, is also likely benefiting, drawing in a staggering 15 million in three days, besting the record 10 million in three days by last year’s battle royale sensation Apex Legends.
  • These new heights follows similar effects of the virus on China and Italy: Telecom Italia’s CEO told Bloomberg it saw a 70% increase in traffic over its landline network, with Fortnite playing a significant part, while Chinese live-streaming service Douyu experienced increased viewership of the country’s most popular games, according to market analyst Niko Partners.
  • While gaming was considered “recession proof” during the 2008 market crash, stocks aren’t immune to the current historic drops: software developers like Activision Blizzard are facing a 9% decrease in price year-to-date, while hardware companies that rely on Chinese manufacturing like Nintendo are seeing bigger drops of 24%.

What To Watch For: If these records keep rising as the closings and lockdowns continue. Arriving this week is Nintendo’s long-awaited Animal Crossing: New Horizons for the Switch console, a relaxing “life-simulator” that’s set to have a big day with many fans not-so-jokingly asking Nintendo to launch early.

Surprising Fact: Plague Inc., a game that tasks players in creating a virus that wipes out humanity, surged in popularity late January, becoming the top-paid game on the Chinese app store at one point, but the game has now been removed in China at the direction of the government.
