3D Print 200 Million Year Old Dinosaur Skull From CT Scan!

For those interested, you can now 3d print a dinosaur skull from a full recreation of a 200 million-year-old dinosaur, thanks to PhD student Kimberly Chapell, from the University of the Witwatersrand in Johannesburg, South Africa.

The dinosaur, known as Massospondylus carinatus, lived in the Early Jurassic. Found in the upper Elliot to lower Clarens Formations of South Africa and Lesotho. One of the first dinosaurs ever described in the importance of South African Paleontology for the study of dinosaur evolution. 

Until now, research has been restricted on M. carinatus due to a lack of detailed internal cranial descriptions.  Thus the current research aimed to produce a 3D representation of the braincase and skull of M. carinatus.  Allowing researchers to describe the cranial anatomy and internal structures and in turn, making it possible for them to establish possible cranial autapomorphies of M. carinatus.

Massospondylus was a mid-size sauropodomorph, around 4 meters (13 ft) in length,  weighing approximately 1,000 kilograms (2200 lb). Researchers have long debated its diet and lifestyle, though recent studies strongly suggest that it was herbivorous or omnivorous, not carnivorous. Interestingly, scientists have also found fossils where these dinosaurs had rocks inside their stomachs. This was interpreted as a gastric mill, to aid ingestion of plant material, compensating for its inability to chew – as is common with several modern birds.

Thanks to Kimberly Chapelle, the 3d scan is available for free download. So anyone wanting to 3D print their own dinosaur skull can do so.

3D Printing Degradable Biomaterials

Using a stereolithographic technique, biomaterials can now be printed for the purpose of being put through a controlled degradation using ionic crosslinking. This, in turn, could become useful for new applications that require a biomaterial that is adaptive and responsive to certain stimuli such as drug delivery applications.

Stereolithographic printing typically uses photoactive polymers that link together with covalent bonds — which are strong, but irreversible. A research team from Brown University experimented with using potentially reversible ionic bonds to create 3D printed structures.

A simplistic view would of using a 3D printer is to build attachments between polymers then remove them when needed. Basically building a support for a structure then removing the support once the structure is ok to stand on its own. They can pattern the transient structures then dissolve away when needed.

Using different compounds derived from seaweed and using different combinations of ionic salts, researchers were able to create structures with a varying stiffness that could be dissolved away at different rates.

The research demonstrated that temporary alginate structures could be useful for making lab-on-a-chip devices with complex microfluidic channels and for making dynamic environments for experiments with live cells. To demonstrate, researchers surrounded alginate barriers with human mammary cells and observed how the cells migrated when the barrier was dissolved.

For 3D Printing Inspiration, Some Fascinating Scrap Metal Sculpture

This Artist Turns Scrap Metal Into Incredible Animal Sculptures

Ok, here is something that might not be related directly to 3D printing but it may provide some good 3D printing inspiration. Some very incredible animal sculptures made out of scrap metal.

I could definitely see some of these being modeled and printed on a 3D printer then assembled with some articulation or just to look pretty.

Anyway, here you go. Let me know what you think.

Inspired by the native wildlife in his hometown in rural West Wales, artist and animal lover J. K. Brown creates incredibly detailed animal sculptures from fragments of discarded metal (talk about creative recycling). He patiently reassembles these pieces into wonderful metal models of birds, butterflies, horses and even dragons! […]

“Maverick” 3D Printed Pilot Skull

Here is another cool 3D print that you can do at home. A 3D printed skull, aka Maverick the pilot skull!

This one was submitted by Paul Braddock at myminifactory.com

This was originally made as a pendant, however, people were asking for a more display friendly version, without the top loop.

We think it is above and beyond in detail when compared to most modeled skulls. Very creative use of detail in his design including the helmet and face mask.

This image shown here was printed by Paulo Ricardo Blank. Printed on a Minibot 120 3D printer:

The Design Process For A 3D Printed Airsoft Gun Holster

This is an older article I came upon while combing the internet for cool information on 3D printing. It came from a makerspace blog located in Southampton, UK. A nice short tutorial on designing a new holster for a modified airsoft gun.

Starts with a little intro on what the model looked like in Autodesk123D all of the way to the finished product. A very short and sweet insight of the design process. If you enjoy, please leave a comment or click on one of the share icons.

On Saturday 7th August, SoMakeIt Member Lee came to the space with an interesting challenge. He had purchased a torch attachment for an Airsoft gun which he was using for a costuming project, but the large barrel of the torch meant that the gun no longer fitted in the supplied holster. So of course we decided that using 3D printing we could quickly make a replacement that fitted perfectly.

Snapmaker : The All-Metal 3D Printer/Laser Engraver/CNC Carver

Doing some casual research on Kickstarter, we came across a cool new 3D Printer that has some very cool features along with being very modular. Enjoying attachments for 3D Printing, Laser Engraving, and CNC carving. To top things off it is also made entirely of metal.

This machine looks to be a promising new entry into the small footprint of 3D printers. While it is not as bulky as some printers it packs a serious punch with all of the added cool features.

After many stages of analyzing the mechanical design and making prototypes, we’ve developed the Snapmaker 3D Printer to provide an enjoyable user experience. Moreover, It’s also a desktop makerspace, a combination of 3D printer, laser engraver, and CNC machine with interchangeable heads. We can’t wait to share it with the Kickstarter community and have you help nurture this unique machine with us.

It appears that it is very easy to swap out each head for whatever your next project requires. The modular design makes it fairly inexpensive and affordable for most. The metal extrusions enable a low-cost machine but high tolerance capabilities.

Snapmaker has an innovative modular design, which enables a flat-packed and low-cost shipping, quick assembly, strong expandability and manufacturing cost reduction. In particular, we designed a new type of linear module, which can be used in any of x, y, z direction and performs high precision linear motion.

According to the manufacturer, you can setup the printer in under 10 minutes. 10 parts in 10 minutes seem like it is very doable. Not something you can say about many other 3D printers.

 

No more hassle of prying loose your print from the print bed! Snapmaker comes with a hassle-free and reusable platform sticker, offering better results than traditional blue painter’s tape and glue sticks. Prints stick well on the printing sticker base and are easy to remove when completed.

Unfortunately, all of the $199 and $249 options are gone, but if you catch it early enough, you can get the next step up at $299 or more if you want to add laser engraver and/or CNC attachments.

Worlds first 3D Printed Skyscraper in Dubai!

Worlds first 3D Printed skyscraper to be built by a Dubai construction technology firm, Cazza.

Cazza announced plans to build the first of its kind 3D printed skyscraper using a new technology called ‘crane printing’. Cazza will outfit cranes with added units created specifically for use in 3D printing tall building structures.

CEO of Cazza, Chris Kelsey, said: “When we first thought of implementing 3D printing technologies, we were mostly thinking of houses and low-rise buildings.

“Developers kept asking us if it was possible to build a 3D printed skyscraper. This led us to begin researching how we could adapt the technologies for taller structures.

Through these technologies, it will be awesome to see how fast a skyscraper will go up compared to standard construction methods. Not to mention what materials will go into the 3D printing process itself.

The cranes will print specific parts of the building while the rest of the construction is to be completed through normal construction methods.

Using existing cranes and outfitting with new 3D printing equipment will save time and cost opposed to having to build a complete 3d printing/crane from scratch.

One can see how a standard crane could be easily adapted to the 3D printing process.

According to Xavier Hernand, mechanical engineer at Cazza, the printing process will include components typically required for tall buildings such as steel rebar.

Xavier Hernand, mechanical engineer at Cazza, said: “The material side leaves vast possibilities with concrete and steel being just one of many materials that can be used with 3D printing.”

Cazza’s crane printing process includes all major structural components required for tall buildings, including reinforcement with steel rebar.

The cranes will 3D print specific parts of buildings, with the rest of construction undertaken through existing methods.

Fernando De Los Rios, chief operating officer at Cazza, added: “The crane printing system can be easily adopted with existing cranes which means we don’t have to build cranes from scratch.

“We are adding new features to make it adaptable to high wind speeds along with the use of our layer smoothing system that creates completely flat surfaces. You won’t know its 3D printed.”

Cazza has already been in the 3D printing construction business using mobile 3D printing robots with existing construction methods to lower costs, speed up development processes, and also make things more environmentally friendly.

Has Ultimaker Turned to The Dark Side? Dutch Manufacturer Files First Patent

The world renown Dutch 3D printer manufacturer, and leader in the open source 3D printer community, Ultimaker, has filed its first patent.

The patent in question is NL2015361:

According the present invention a print bed levelling system of the type defined in the preamble is provided, wherein the print bed levelling system comprises a nozzle head assembly movably arranged with respect to a substantially flat print bed member, the nozzle head assembly comprising one or more nozzle bodies each having a nozzle end, and a contactless sensor member disposed at a print bed engagement end of the nozzle head assembly, wherein the contactless sensor member comprises a sensing surface in sensing engagement with the print bed member over a relative sensing range between a distal sensing position and a proximal sensing distance.

– Reference: NL2015361

Has Ultimaker gone over to the Dark Side? At first glance, it would seem that way. But not so fast says the Ultimaker Community and Event Manager Sander Van Geelen. “Owning a patent is one thing, but how we act upon it is another.

Sander went on to state that they will not change their behavior and attitude toward other users and goes on to explain why the patent is necessary for a company that has made their roots in open source.

Well, with the Ultimaker 3 in particular, we are tapping into a new market of enterprises and competitors who play a whole different game. Forcing the competition out of the market through lawsuits and court is not uncommon. And we need to be prepared. Hence this defensive strategy.

It seems their intention is not to flex their muscles with casual users but to continue supporting collaborations and help stimulate research.

They also plan to keep sharing the files of the Ultimaker 3 and so on at their Ultimaker GitHub page. The file sharing should help alleviate some fears as to their real intentions.

When you think about it, it makes total sense as to why Ultimaker would want some protection from the harsh tactics of big business.

Only time will tell how this affect the relationship between them and the open source community. For now, we will have to take their word on it. If you have an opinion and would like to share then, please leave a comment below.

3D Printing Pioneer Janne Kyttänen’s Resigns From 3D Systems

 

Rumor has it that Janne Kyttanen has resigned from his position with 3D Systems. Janne, a conceptual artist, and designer, is best known for his work in 3D printing. Founder of the “Freedom of Creation” studio and up until now Creative Director of 3D Systems, his work has been exhibited in museums and galleries around the world. Not to mention his time spent as a pro squash player, playing in two different world championships and also two team championships.

Well known for leading the pack in design for 3D printing, his studio, Freedom of Creation, was one of the first to work with in implementing 3D printed designs along with using rapid prototyping to produce textiles.

For the span of his career, his work has won numerous awards while being displayed in many museums, galleries, fairs and exhibitions throughout the world.

After selling his companies to 3D systems he spent time learning how things work in the corporate world. The experience of running into roadblocks while working toward bringing new ideas to the consumer side of 3D printing he soon realized that the corporate world was more interested in the industrial side. Taking this as a clear sign there was no purpose for him at 3D Systems he decided to jump ship and start a new journey. A journey to hopefully alleviate some of the roadblocks that do not add value. His new company ‘What The Future Venture Capital’ is working toward taking out the inefficiencies that the corporate world brings.

Janne Kyttanen – 3D Printed Sofa

In a recent interview, he was asked if 3D Printing is overrated in its use for the consumer market.

Yes, at the moment 3D printing is totally overrated . Only a selected few have machines in their homes. I still believe in the industry though. In the last 25-30 years, it has been growing steadily with 25-30% every year. There will surely be more consumer machines, especially now that the Chinese have joined the race and are cutting prices at an astonishing rate. However, it will take a lot longer than people expected.  […]
