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.

5 Ways Tech Can Revolutionize Education

Published

on

Professor Sally Smith, Dean of School of Computing at Edinburgh Napier University, was in South Africa to share how tech can revolutionize education and what Africa can learn.


With the Fourth  Industrial Revolution gaining speed, the nature of work and economic activity is set to dramatically change. One woman is on a mission to prepare the education system for such changes.

Professor Sally Smith, the Dean of School of Computing at Edinburgh Napier University, traveled from Scotland to South Africa to share her know-how, as one of the speakers at the Future of the Education Summit in Johannesburg.

Hosted by Africa Business News, the summit brought together thought-leaders and professors from all over the world. Smith met FORBES AFRICA a day before the summit to speak about her experiences in the education industry for 26 years:

1.What trends have you picked up in the sector over the years?

In terms of technology, it has been very fast-moving so the big challenge for universities is conducting research and translating that into useful programs for students when they graduate.

In terms of the kind of trends and developments, we have seen huge growth in areas such as creative computing. There have been developments around designing meaningful interactions with computers, and that’s no longer just [limited to] a desktop computer; that will be your mobile phone, it’ll be augmented reality systems, virtual reality systems and other recent trends like cyber security.

With more of our lives being conducted online, there’s a need to make sure we secure our data security, our identity is secure and businesses as well need to protect themselves. Those have been really interesting ways in which I have seen a big change in recent years.

And the other thing that has changed is there has been a lot of growth in AI. Some of those kinds of machine learning tools are now being put to wider use than ever before by things like self-driving cars. So that’s an area of great interest now to our students and when they graduate to apply these algorithms.

2.What do you think are the challenges in this sector?

One of the things we’ve been disappointed with in much of the western world is how few women are interested in studying computer science and it has been fairly constant at sub-20% of our undergraduate program since I have been in academia. And we have really been unable to make any great inroads into changing that.

3.What differences have you picked up between education in Scotland and South Africa?

Making sure graduates have the right skills to go to work, and part of that is getting work experience and it’s a challenge for all of us to make the case for businesses to take on a student so they can take on relevant work experience before they graduate. Some of the challenges I have seen around are about trying to get those partnerships.

4.How do you see collaborations of universities around the world with the 4th Industrial Revolution?

Yes, I think there are fantastic ways we collaborate over research and a lot of the big funds now are only interested in collaborations where we can draw on the strengths of universities from different countries and I think that the same will be true about teaching.

READ MORE |Is This Technology the Answer to World Hunger?

At the moment, we are competing with each other but if we can put great programs together that draw on the strength of different universities, there’s a future for more collaborative work.

5.How can the private sector help upskill young people?

We’ve introduced a new way in which people can get degree level qualifications in the UK and degree level apprenticeships. Industry will employ someone and they attend university 20% of the time and work towards their degree while they are in work.

So that is a new way to make sure the degree is appropriate for employers and these programs are employer-led so employers are part of designing the program. The other project we have is a digital skills partnership which is where we try and get industry and lecturers to work more closely together on things like developing curriculum.

Banks Are Promoting ‘Female’ Chatbots To Help Customers, Raising Concerns Of Stereotyping

Published

By

Meet Amy. And also Debbie, Inga, Mia, Erica, Eva and Cora.

These aren’t the members of a new, all-female rock group, but names that several large banks have been giving to their automated digital assistants.

So-called chatbots have become a useful cost-cutting tools for companies with large subscriber bases (think banks, insurance firms and mobile phone operators). As they replace human call-center workers, such bots will help save banks an estimated $7.3 billion in operational costs by 2023, Juniper Research predicts.

But the proliferation of bots with female names raises questions about whether they might also perpetuate gender stereotypes, particularly around the notion of women in the role of assistants. That criticism has already been levelled at Amazon’s digital assistant Alexa and Apple’s Siri.

Now a Forbes analysis of Europe’s 10 biggest banks ranked by assets shows that at least three have deployed chatbots with female names on their websites and apps. HSBC has a chatbot named Amy; Deutsche Bank’s Debbie helps market traders; ING of the Netherlands has Inga, a chatbot that will “respond with empathy” to customer problems such as losing a card.

ING’s other chatbot Marie, available to retail customers on Facebook Messenger, was given the name “because it conjures up an image of someone who is helpful and friendly,” Tim Daniels, a programme manager for ING was quoted as saying on the bank’s website. (ING has a male chatbot named Bill, aimed at dealing with corporate customers.)

Among the other lenders, Santander, Barclays and Societe Generale appear to have unnamed chatbot assistants. Credit Agricole has an internal chatbot with a male name: Hector.

Female chatbots abound in other regions and industries. Bank of America recently deployed a digital assistant called Erica, while Mia, the chatbot released by Australian digital bank UBank, was described by the company earlier this month as “empathetic,” “fun” and “a little bit cheeky.”

IPSoft, a New York-based software company that sells chatbot technology to banks like Sweden’s SEB as well as mobile network giant Vodafone, has its own white-label version of a customer-facing chatbot, named Amelia.

IPSoft’s CEO Chetan Dube denied that the chatbot’s name perpetuated stereotypes, when asked by Forbes during an interview in December, and said it instead highlights “the thought leadership that is represented in females.”

“She was the first female aviator that tried to go around the world,” Dube added, referring to the 1930’s aviator Amelia Earhart.

Forbes revealed earlier this month that Vodafone was measuring the success of its chatbots on how many staff could be replaced by the software. While that may be an uncomfortable metric, the more worrying consequence of chatbots, according to four industry experts questioned by Forbes, is the risk that they could reinforce certain stereotypes.

“Gender bias is an increasingly serious issue in chatbot design, especially for voice-based chatbots,” says John Taylor, CEO of action.ai, a British startup that makes chatbot software for banks and travel companies. “These assistants often perform tasks that many view as menial.”

Vitor Shereiber, a language specialist at the German language-learning app Babbel, says that focus-group testing might lead companies to assign a gender to a chatbot on the notion that it makes customer feel more comfortable.

But, he adds, bots could spread unrealistic expectations of how women should present themselves professionally, just as photoshopped pictures have done for women’s perceptions of their bodies.

Part of the challenge for companies is finding a balance between automating customer service without putting customers off. PwC recently described chatbots as being able to “massively enhance customer delight and loyalty” because of their “personal touch.”

Taylor suggests software designers should try creating more chatbots with male names and male voices.

On the sidelines of a technology conference in London on Wednesday, Seth Juarez, an artificial-intelligence engineer based in Redmond, Washington takes it a step further. He calls Siri up on is iPhone to ask the time, and a male voice responds.

“I make it a guy specifically because I find it morally reprehensible that all of the service-based bots are female, and all the intelligence based bots [like IBM’s Watson] are named after dudes.”

He added that artificial intelligence generally shouldn’t be anthropomorphised. Chatbots should be used to manage “cheap thoughts,” or “stuff that a human would do robotically” rather than on more complex issues. “I would leave those problems to humans.”

BMW And Daimler Pool Resources On Automated Driving Technology

Published

on

By

Daimler and BMW deepened their alliance on Thursday to share spiraling development costs for highly automated driving technologies, even as each carmaker pursues separate efforts to develop fully self-driving cars.


The enormous cost of designing and building computer-powered vehicles has already prompted Honda to pool its efforts with General Motors, while Volkswagen is pursuing talks with Ford about an alliance on autonomous cars.

BMW and Daimler deepened their alliance for similar reasons, said Michael Hafner, head of automated driving at Mercedes-Benz research and development said in a blog post which accompanied a joint press release by the companies on Thursday.

“We have learned that the development of these systems is a bit like climbing a mountain,” he said.

“Taking the first few meters from the base station to the summit seems easy. But the closer you come to the goal, the thinner the air around you becomes, the more strength is required for each further step, and the more complex become the challenges you have to resolve.”

It made sense to distribute the technological and financial challenges of automated driving, Hafner said, so BMW and Daimler will jointly develop technology to enable automated driving on highways.

“Initially, the focus will be on advancing the development of next-generation technologies for driver assistance systems, automated driving on highways and parking features,” the companies said in the statement.

“In addition, the two partners plan to discuss the possibility of extending their collaboration to cover higher levels of automation, both on highways and in urban areas.”

BMW and Daimler’s move comes as even deep pocketed technology companies struggle to gain traction in autonomous driving. Apple Inc said on Wednesday it planned to lay off 190 employees in its self-driving car program, Project Titan.

The market for advanced driver assistance systems and autonomous vehicles is expected to grow to $96 billion in 2025 and $290 billion in 2035 from about $3 billion in 2015, according to Goldman Sachs.

BMW and Daimler already cooperate in high-definition mapping with HERE and in the area of procurement, and earlier this month unveiled a joint ride-hailing, parking and electric car charging business.

They said on Thursday their new partnership will center on so-called level 3 and level 4 automated driving technologies, including cars that still require steering wheels and drivers.

Daimler will pursue a separate development alliance for level 5 robotaxis between its luxury brand Mercedes-Benz and supplier Robert Bosch. Level 5 cars require no driver.

BMW, for its part, continues its development alliance for robotaxis with Israeli autonomous vehicle tech company Mobileye and chip maker Intel, with the aim of putting autonomous cars on the road by 2021. -Reuters
