3D printing: What would Da Vinci say?

Published

on

When relatively new technology receives the endorsement of a megastar such as Black Eyed Peas will.i.am, its popularity skyrockets and suddenly the application possibilities seem endless.

Appointed recently as the chief creative officer of a global 3D printing company, will.i.am has set about taking 3D printing beyond the limited reach of staunch tech enthusiasts. His aim is to promote a simple-to-operate 3D printer that would reduce material waste by using recycled materials. This effort to promote sustainable living and highlight the environmental impact of manufacturing is only the tip of an iceberg that is both mind-blowingly large and infinitely useful.

 

 

“3D printing has been around for some time. However, consumers have recently begun to become more engaged in the 3D printing value chain,” says Simon Bromfield, Channel Manager at Adobe Systems Sub-Saharan Africa. “When most people talk about 3D printing, the focus is on the printers. But what will ultimately drive the growth of the consumer 3D printing market is the availability of content that is compelling to consumers.”

3D printing or additive manufacturing is being developed and adapted to spread its influence across a number of sectors and processes. 2014 has seen a number of significant breakthroughs in the use of this technology. Swedish supercar manufacturer, Koenigsegg recently unveiled the One:1, a supercar that utilises many components that were 3D printed. This year, 3D printing has begun to be used in production versions of spaceflight hardware. Healthcare advances have also been profound: scientists are using 3D printing and living tissue to produce ears, kidneys and livers.

But one of the most rapidly evolving applications of 3D printing is taking place in the creative space. Sculptors, modelers, artists, concept designers, illustrators and even jewellers and architects are embracing the potential of 3D printing to create complex objects that could not be made in other ways.

“A big part of what influences the value of content has to do with colour. Much of the content created today is monochrome, but with the right software, creative and designers have the control and flexibility to add colour, polish and texture to transform a 3D object into something meaningful and vibrant,” says Bromfield.

Designer Francis Bitonti, well known in design circles for a 3D printed gown that he created for fashion icon Dita von Teese, sees computational methodologies, smart materials and interactive environments as an opportunity to create new aesthetic languages for the creative industry.

“My design process is a collaboration with artificial intelligence,” says Bitoni. “We are transposing these ideas from design methodologies to tangible consumer experiences.”

In order for creatives to produce inspirational pieces, many of them are working with software that is developed specifically for the production of physical output.

Tobias Klein, architect and creator of The Garden of Earthly Delights, an art piece orientated on the work of Hieronymous Bosch and featured at the 3D Print Show London 2014, explains its use in practice: “We use Photoshop CC distinctively at the front end in its capability to quickly generate artwork and colour schemes for the later application onto the models. This helps us considerably to communicate the design in a fast and effective way as we can export the painted models between various platforms.”

“3D printing has opened up a creative pathway that is fantastical, boundless and alive with possibilities,” says Bromfield. “The production of high quality full colour content is already changing high-end jewellery, sculptures, household goods, fashion and architecture. Technologically advanced software can turn visionary design ideas into tangible reality.”

Android Go puts reliable smartphones in budget pockets

Nokia, Vodacom and Huawei have all launched entry-level smartphones running the Android Go edition, and all deliver a smooth experience, writes BRYAN TURNER.

Published

on

Three new and notable Android Go smartphones have recently hit the market, namely the Nokia 1, the Vodafone Smart Kicka 4 and the Huawei Y3 (2018). These phones run one of the most basic versions of Android while still delivering a fairly smooth user experience.

Historically, consumers purchasing smartphones in the budget bracket would have a hit-and-miss experience with processing speed, smoothness of user interface, and app stability. The Google-supported Android Go edition operating system optimises the user experience by stripping out non-important visual effects to speed up the phone. Thish allows for more memory to be used by apps. 

Google also ensures that all smartphones running Android Go will receive feature and security updates as they are released by Google. This is a major selling point for these smartphones, as users of this smartphone will always be running the latest software, with virtually no manufacturer bloatware.

Vodafone Smart Kicka 4

At the lowest entry-level, the Vodafone Smart Kicka 4 performs well as a communicator for emails and WhatsApp messages. The 4” screen represents a step up for entry-level Android phones, which were previously standardised at 3.5”.

The display is bright and very responsive, while the limited screen real estate leaves the navigation keys off the screen as touch buttons. It uses 3G connectivity, which might seem like an outdated technology, but is good enough to stream SD videos and music. Vodacom has also thrown in some data gifts if the smartphone is activated before the end of September 2018. 

Its camera functionalities might be a slight let down for the aspirant Instagrammer, with a 2MP rear flash camera and a 0.3MP selfie snapper. Speed wise, the keyboard pops up quickly, which is a huge improvement from the Smart Kicka 3. However, this phone will not play well with graphics-intensive games. 

Nokia 1

Next up is the Nokia 1, which adds a much better 5MP camera, improved battery life and a bigger 4.5” screen. It supports LTE, which allows this smartphone to download and upload at the speed of flagships. It also sports the Nokia brand name, which many consumers trust.

Although the front camera is 2MP, the quality is extremely grainy, even with good lighting. This disqualifies this smartphone for the social media selfie snapper, but the 5MP rear camera will work for the landscape and portrait photographer. 

The screen also redeems this smartphone, providing a display which represents colours truly and has great viewing angles. Xpress-on back covers allows the use of interchangeable, multi-coloured back covers, which has proven to be a successful sales point for mid-range smartphones in the past. 

Huawei Y3 (2018)

The most capable of the Android Go edition competitors, the Huawei Y3 (2018) packs an even bigger screen at 5”, as well as an improved 8MP rear camera and HD video recording. The screen is the brightest and most vibrant of the three smartphones, but seems to be calibrated to show colours a little more saturated than they actually are. 

Nevertheless, the camera outperforms the other smartphones with good colour replication and great selfie capabilities via the 2MP front camera – far superior to the Nokia 1 despite the same spec. LTE also comes standard with this smartphone and Vodacom throws in 4G/LTE data goodies until the end of September 2018. The battery, however, is not removable and may only be replaced by a warranty technician.

Comparing the 3

All three smartphones have removable back covers, which provide access to the battery, SIM card and SD card slots. The smartphones have Micro USB ports on the bottom with headphone jacks on the top. The built-in speakers all performed well, with the Y3 (2018) housing an exceptionally loud built-in speaker. 

Although all at different price points, all three phones remain similar in performance and speed. The differentiators are apparent in the components, like camera quality and screen quality. It would be fair to rank the quality of the camera and battery life by respective market prices. The Vodafone Smart Kicka 4 performed well, for its R399 retail price. The Nokia 1, on the other hand, lags quite a bit in features when compared to the Huawei Y3 (2018), bwith oth retailing at R999.

The southafrica.co.za  site carries content about the country’s collective heritage in South Africa’s eleven official languages.

Designed as a nation building,  educational and brand promotion web based tool, the free-to-view platform features award-winning photographic and written content by leading South African photographers, authors, academics and photojournalists.

The emphasis is on quality, credible, factual content that celebrates a collective heritage in terms of the following: Cultural Heritage; Natural Heritage; Education; History; Agriculture; Industry; Mining; and Travel.

At the same time as reflecting on the nation’s history, southafrica.co.za celebrates South Africa’s natural, cultural and economic assets so that the youth can learn about their nation in their home language.

Southafrica.co.za Founder and CEO Hans Gerrizen conceptualised southafrica.co.za as a means for youth and communities from outlying areas to benefit from the digital age in terms of the web tool’s empowering educational component.

“We can only stand to deepen our collective experience of democracy and become a more forward planning nation if we know facts about our nation’s past and present in everyone’s home language,” he says.

Southafrica.co.za, with sister company Siyabona Africa, is the organiser and sponsor of the Mandela: 100 Moments photographic exhibition that runs until 30 September at Cape Town’s V&A Waterfront-based Nelson Mandela Gateway to Robben Island.  The 3-month exhibition, which runs daily from 08h00 until 15h00, is showcasing one hundred iconic Nelson Mandela images taken by veteran South African photojournalist and self-taught lensman Peter Magubane.
