3D Printing: The Stories We Didn’t Cover This Week – April 11, 2015

This week’s 3D printing stories we didn’t cover run the gamut from quite serious to whimsical, beginning with serious news of an MIT student’s use of 3D printing to document his brain tumor diagnosis and treatment, to a new Minecraft-inspired 3D design app, more Ultimaker files released, Taiwan’s new Fab Trucks, an Instructable for a homemade 3D scanner, and fun printed fashion and food news, too.

MIT Doctoral Student Documents Brain Tumor

Steven Keating, an MIT doctoral student in the Mediated Matter Group, used 3D printing to document his experience during the diagnosis and treatment of a tennis ball-size brain tumor. Keating’s experience and background in data management and additive manufacturing was used to create digital and 3D printed models of his tumor, brain, and skull surgery. Not only did he intend to share important medical knowledge with people in similar situations, but he also wanted to show how 3D printing can help people take charge and be centrally involved in their own medical treatment. And he did just this. His surgery was videotaped and he’s advocating an open approach to usually private medical information in the spirit of collaboration, with 3D printing centrally involved.

Minecraft-Inspired 3D Design App Launches

A Minecraft inspired UNTITLED Creator app created by Thailand-based Treebuild makes 3D design more fun and user-friendly at the same time. You can use theLUBAS app to make pixelated artwork while also nostalgically indulging in Minecraft-esque imagery. Even better is that you can easily export your designs or choose to save the work into STL, OBJ, X3D, 3DDOM, HTML, or VRML. You can also send them to a 3D printing service that can print the design and ship them to your doorstep. We covered its beta release last month, and now the app is up and running.

Ultimaker Releases More Open Source Files

3D printer manufacturer Ultimaker has gone out of its way to facilitate its customers’ central involvement in the making and upgrading of their 3D printers. The company continues to show its commitment to the open source movement and the maker spirit, recently launching its Ultimaker Original+ and Ultimaker heated bed upgrade files, which you can access on GitHub.

Printer manuals, assembly instructions, and mechanics are all improved with the launching of these files, and the company continues to express its dedication to customers as the 3D printing technology develops and evolves.

Taiwan’s Fab Trucks for 3D Printing High School Education

Taiwanese officials have shown great support for 3D printing technology, and in a recent turn of events, the country has decided to dedicate resources over the next two years to ensure more high school age students gain exposure to 3D printing. Fab Trucks — maker labs on wheels — will visit almost 500 high schools throughout Taiwan, reaching 160,000 students and teachers. The Ministry of Education has spent $224K (USD) on the six laboratory trucks equipped with professional 3D printing-related equipment. This equipment includes DLP (light curing) and FDM 3D printers, laser cutters, a CNC milling machine, and additional accessories and materials. Students will be encouraged to use the trucks as much as possible when they are available on their campuses in the hopes that Taiwan and the world will see a new generation of makers and 3D printing innovators on the horizon.

FIT Student 3D Prints Captivating Fashion Piece

The relevance of 3D printing for a growing number of students can also be found in a Fashion Institute of Technology student’s project that used 3D printing to make an elaborate neck and matching dress piece. Rachel Nhan took her class assignment theme “Mad Max Meets the French Court” to heart as she designed a piece that perfectly merges these seemingly disparate themes into one captivating design.

After considering 25 different design concepts, Nhan used Autodesk Maya to create the selected model, which was split into 14 pieces and 3D printed by FIT’s PrintFX Lab on a uPrint Stratasys Machine with a 6″ x 8″ x 6″ printing bed. Nhan reports having some difficulty fitting the different components onto the print bed, but you would never know she had any difficulties by looking at the finished product. Capturing the Mad Max/French Court theme quite well, Nhan’s piece is also a reminder of 3D printing’s growing popularity in the fashion design world, as more and more people rely on it to realize their own customized, outlandish, and futuristic fashion visions.

Danish Teacher Makes 3D Scanner

While students (like FIT’s Nhan) continue to use 3D printing in a wide variety of applications, teachers are also a standout source of knowledge and innovation in the 3D printing scene. Using webcams, a video projector, and other household items, Danish teacher Hesam Hamidi has made a perfectly functional structured light 3D scanner — a scanning device that measures objects’ three-dimensional shapes using a camera system and projected light patterns. This project is called “HHSL3DS” and Hamidi, who has been working in Denmark’s Copenhagen Fablab for some time, shared all of his designs and even the software and code he has written for it online. You can find entire tutorial, as well as all the downloadable files, on Instructables.

World’s First 3D Printed Food Conference in Netherlands

For those who get excited about the merging of culinary arts and 3D printing technology, good news: the world’s first 3D printed food conference will take place in Venlo, the Netherlands on April 21, 2015. This conference promises to bring printed food from “hype to reality,” while addressing important questions such as: “Which industries will be influenced by the technology?” “Which food components can be printed in the near future?” “Which aspects should be taken into account to ensure safety and maintainability of 3D printed food?” Also, topics to be explored, which are also listed on the official conference website, include: food components (protein, carbohydrates, and fats); custom nutrition; food processing and design; safety issues; new value chains; applications for the elderly and the health care industry; hardware and software developments; business models and legal issues. There’s still time to register on the conference website if you are in that growing group of 3D printed food fans!

3D Printing’s Musical Journey

Friends, customers, printaholics – lend us your ears and join us along a 3D printed musical adventure!

A recent post which featured one of Malta 3D Printing’s favourite little musical toys – a kazoo – inspired us to continue down this musical vein.

To place things into perspective, the 3D printable instruments of today are split into three categories.

Firstly, we have ‘experimental pieces’, which don’t have a conventional equal outside of the realm of 3D printing. Secondly, there are ‘enhanced instruments’, which improve the qualities of an already existing instrument thanks to 3D printing’s unique capabilities.

3D Printing Will Soon Turn This Design Into Reality

Finally, we have replications of existing instruments, which have no real added benefits compared to the traditional piece.

Pictured above is a prime example of a 3D printable musical piece still in experimental stages.

This unusual trumpet is reminiscent of a modern painter’s masterpiece rather than a practical musical device.  While this aesthetically pleasing instrument is yet to be created, there are others which are already in circulation.

The video below provides a quick explanation about a 3D printed flute. Using the powerful Objet500 Connex, this wind instrument’s 3D model was produced using Rhino.

In a different interview, flute player Seth Hunter emphasized the plastic flute’s acoustic similarities to the traditional metal ones. He also noted the slight misplacement of the keys – but remember – 3D printing encourages technicians to fix any minor errors in the subsequent print.

Created by yet another student from MIT, Amit Zoran was not far away from creating an exact replica, and this was way back in 2011. The traditional flute falls under the ‘existing instrument’ category, but our next pick certainly has its fair share of enhancements.

A laser-cut violin made from plywood, this stringed instrument was created by Ranjit Bhatnagar, a sound art enthusiast.

Its’ bulky wooden outer shell provides a stern contrast to the graceful sounds it can produce. Bhatnagar even took his masterpiece to the streets, inviting different violin players to fiddle away. Check out the videos here!

An ‘Enhanced Instrument’ – 3D Printed Violin

‘Ranjit’ as he is known on Thingiverse, has a personal page chocked full of free designs for different instruments – including an okarina, organ pipe, spiral panpipes and more.

Next up is another piece seeking to replicate an original design, but this one is slightly different. At four feet long, this home-made behemoth requires many printing sessions.

Clearly, this great bass recorder functions well – and the creator has since improved on his original work. The recorer is made up over 48 inches of PVC pipe measuring 1.5″, a few sections made of 2″ and multiple, custom built 3D pieces.

Created by Instructables user ‘sngai’, a quick internet search will reveal that opting to print this object as opposed to purchasing a store-bought one will save players a lot of money.

Who knows what the future holds? PLA pianos, ABS acoustic guitars and printable drum kits may soon become popular. As the number of 3D printed instruments continues to grow, its only a matter of time before musicians hop on the fast-moving bandwagon!
