The Natural History Museum’s well known and much loved dinosaur skeleton, nicknamed Dippy, is going on tour in the UK. Visitors can now get hands-on with the dinosaur thanks to 3D printed replica skulls.

London’s Natural History Museum is the permanent home of the Diplodocus dinosaur, nicknamed Dippy. However, the popular dinosaur is now going on tour throughout the UK. As a result, a further five million people will have the chance to view the bones.

But not only will visitors get the chance to view the complete dinosaur, they’ll also be able to get up close to Dippy’s skull. Belfast’s 3D printing specialist Laser Prototypes Europe (LPE) was deployed to create eight exact replica skulls.

In order to do this, Dippy was laser-scanned from head to tail last year. This process captured the dinosaur’s exact size and shape including the smallest of details. LPE was then able to use the data to 3D print the replicas.

“Our process was perfect for recreating the complex free-form shape of Dippy’s skull, giving an exact copy of the scanned data,” explains Campbell Evans, sales director at LPE.

“The project was a really interesting one for LPE, as much of our work is for electronic housings, covers, connectors and everyday engineering components. It’s not every day we see a dinosaur coming through the doors, let alone eight of them.”

Dippy Visiting Seven Locations on the UK Dino-Tour

LPE 3D printed the replica skulls in a single piece from the scan data using lightweight, durable resin. As a result, each of the replicas weighs around three kilograms. By using 3D printing, it’s possible to avoid the traditional mold and cast process.

3D printing is viewed as a safe way to create models. As a result, visitors will be able to touch the replicas and get up close to Dippy during the tour.

Of the final eight skulls, two will be going on tour with the dinosaur. Meanwhile, five will be go to the Real World Science partner institutions for education and one will remain in London for research and study.

The tour began at the Dorset County Museum on the Jurassic Coast and will travel to seven venues, finishing up in Norwich, UK in 2020. Find out more about the tour by visiting the Natural History Museum website.

New Concrete 3D Printing Technique Creates Weaving Structures in Thailand

New Concrete 3D Printing Technique Creates Weaving Structures in Thailand
By Anne Freier

The Thai cement manufacturer SCG has developed a special concrete material to 3D print structures with a unique weaving pattern. The 3D printed concrete technique offers improved structural integrity and a stunning aesthetic. 

Forget what you’ve learned about construction and architecture, concrete is taking on whole new shapes thanks to 3D printing. The Thailand-based cement manufacturer Siam Research and Innovation Company (SCG-SRI) has developed an unbelievably innovative concrete 3D printing technique.

Dubbed “Triple S”, the project combines traditional Thai craftsmanship with additive manufacturing, creating a stunning architectural structure. The Triple S design concept stands for Surface, Structure and Shelter.

The concept derives from a 250-year-old tradition of Thai folk handicraft, which was initially founded in the country’s previous capital Phra Nakhon Si Ayutthaya. This old weaving pattern is a fish-like ornament made of coconut leaf, and is directly integrated into the concrete 3D printing process.

After the concrete block is printed, the weaving pattern is extruded and implemented into the structure, creating a structural truss that is able hold its own weight.

SRI first began using additive manufacturing to print cement material back in 2014. Ever since, it has established a portfolio of impressive designs like the 2015 “Helix” project, which is a range of outdoor shelter designs that resemble shells.

SCG 3D Printable Concrete Offers Structural Integrity and Weaving Aesthetic 

The company states that the primary challenge of the entire process is formulating the 3D printable concrete material. This cement is made from a special formulation that consists of powder and fiber materials.

The concrete needs to be able to dry fast and bond firmly to help twist it into the desired shape. And so, the company uses a formula that resembles bone, strong on the outside, but spongy on the inside. This makes it tougher and more resilient than other types of concrete material.

To showcase the value of the Triple S project, SCG is presenting wall-like structures measuring 3 x 3.5 x 3 meters. The design focuses on both the outer layer and inner truss, giving both sides of the concrete a unique aesthetic and structural functionality.

Moreover, the weaving pattern enables the outer surface layer to offer the structural performance as the inner truss. It also keeps the outer surface from having a delicate and vigorous appearance.

Overall, the SCG designs are more lightweight than traditional concrete structures because the method uses less material. It also provides a compressive strength greater than 45 MPa and the flexural strength greater than 80 MPa.

Last year, SCG also collaborated with Thai artist Anon Pairot to create outdoor terrace 3D printed furniture. Using this specially formulated concrete, Pairot created sofas and tables as part of the “Fluctuation of Precision” project.

Cheddar Man Reconstructed with DNA, 3D Scanning & 3D Printing

Cheddar Man Reconstructed with DNA, 3D Scanning & 3D Printing

A facial reconstruction of the oldest complete British skeleton, the Cheddar Man, is made from DNA analysis, 3D scanning and printing. 

In 1903, researchers discovered the skeleton of what is believed to be one of the early settlers of Britain in Somerset’s Cheddar Gorge. The skeleton became known as the Cheddar Man and researchers have long been trying to reconstruct its face.

The reconstruction of the Cheddar Man’s face was previously based on guesswork. It has long been assumed that the face of the man who lived 10,000 years ago was pale skinned and fair haired.

But thanks to modern technologies like DNA analysis, 3D scanning and 3D printing, the actual face of Cheddar Man is rather different to what researchers first believed.

In fact, Cheddar Man had dark skin with dark, curly hair and striking blue eyes. This update changes our understanding of how lighter pigmentation spread through Europe. Dr Tom Booth from Britain’s Natural History Museum, explains:

“Until recently it was always assumed that humans quickly adapted to have paler skin after entering Europe about 45,000 years ago. Pale skin is better at absorbing UV light and helps humans avoid vitamin D deficiency in climates with less sunlight.”

Cheddar Man Hits the Small Screen

Scientists from University College London (UCL) and the Natural History Museum worked together to use newly available DNA analysis, 3D scanning and printing to reconstruct the Cheddar Man’s face.

They began by drilling a 2mm hole in his skull to collect the ancient DNA. This information was then used by reconstruction specialists. A 3D scan was taken which helped create a 3D model of the skull.

For the printing stage, Minke Van Voorthuizen was enlisted. She used an Ultimaker 3 Extended machine and printed using PLA with PVA support pillars. The print took 13 hours as it didn’t need to be highly detailed. This printed model was used to protect the fragile fossil and provide the foundation for the reconstruction.

Researchers believe Cheddar Man emigrated from Africa via the Middle East when Britain was still connected to Europe. He was 5 ft 5″ and would have been a hunter-gatherer.

“Cheddar Man’s genetic profile places him with several other Mesolithic-era Europeans from Spain, Hungary and Luxembourg whose DNA has already been analyzed,” explains Professor Thomas from UCL.

“These ‘Western Hunter-Gatherer’s’ migrated into Europe at the end of the last Ice Age and the group included Cheddar Man’s ancestors.”

Cheddar Man has received a huge amount of attention from the British public and press. This Sunday, Channel 4 is broadcasting “First Brits: Secrets of the 10,000 Year Old Man”.

Porsche is 3D Printing Metal and Plastic Spare Parts for Classic Cars

Porsche is 3D Printing Metal and Plastic Spare Parts for Classic Cars
By Hanna Watkin

Porsche

Porsche is using 3D printing to reproduce classic car parts which are either extremely rare or extinct. The technology offers an economical way to produce spare parts of high-quality.

As a classic car collector, there’s nothing worse than hearing that a part is no longer available. After an extensive hunt, this can often lead to a car being put out of action.

Porsche Classic, the branch of the company trying to ensure this doesn’t happen, has a solution to the problem. The company is using 3D printing to create parts. What better way to create extremely specific metal parts?

At the state-of-the-art warehouse, the company has around 52,000 parts and components built using traditional methods. However, 3D printing will help recreate those parts which are either very rare or no longer exist. In doing so, they’ll be reducing the time-intensive work for restorers.

So far, the company is working on nine parts and testing a further twenty parts to see whether they’re suitable for printing. One such model is the a release lever for a clutch on a Porsche 959. Only 292 of these parts were ever built, so they’re extremely difficult to come by.

Porsche used 3D printing technology to create the part and pressure tested it with three tons before installing it in a test car and driving it “extensively”. The part passed its tests with ease.

Go for a Ride in a Porsche Classic Built with 3D Printed Parts

To ensure parts meet the specifications of the original parts and are high quality, Porsche is relying on a selective laser sintering (SLS) printer for plastic parts.

Metal parts are all steel and alloy, produced with the selective laser melting process. Porsche explains this process, stating:

“A layer of powdery steel tool less than 0.1mm thick is applied to a processing plate in a computerised process. In an inert atmosphere, a high-energy light beam then melts the powder in the desired locations to create a steel layer.”

A 3D printed part is then built up, one layer at a time. So far, Porsche Classic is impressed with how the 3D printed parts perform during testing.

The company explains that the benefits are economical, reduce waste and warehouse storage space and that 3D design data or a 3D scan is sufficient for production to begin.

As a result, Porsche is now testing whether 3D printing is suitable for the production of a further twenty components, and we’re sure more parts are to come too. Visit the Porsche website to find out more.
