3D Printing a Full-Size Tyrannosaurus Rex Skeleton

In Jurassic Park, Cloning a Tyrannosaurus Rex Amber involves the discovery of fossil dinosaur blood, a whole lot of genetic engineering, and a prodigious disregard for health and well-being. To a team of researchers from the Naturalis Biodiversity Center in Leiden, the Netherlands, mimicking one T rex Some state-of-the-art laser scanning technology, a giant 3D printer, a just-as-large postage bill, around 45 million square millimeters of acrylic paint and a group of experts willing to push the boundaries of additive manufacturing.

Let’s back up. A little over a decade ago, in 2013, a group of paleontologists from the Netherlands discovered a beautifully preserved skeleton of an adult T rex On a dig in Montana. About 75% to 80% of its bone volume remains intact, it was the third most complete T rex Ever discovered

He called his 11,000-pound, 42-foot-long, 66 million-year-old specimen “tricks”.

Trix will now take place at the Naturalis Biodiversity Center (or, at least, again in May when the museum reopens after Kovid). It’s only one of a couple Tyrannosaurus Specimens of permanent exhibitions on mainland Europe.

T rex Skeletons are, perhaps, rare. Since first discovered in 1902 – Hale Creek, Montana – excellent 32 adult names T rex Fossils have been discovered in total. sometimes. It is out of this population that scientists now believe that the species had 2.5 billion in a few million years. To put it another way, out of every 80 million T. Rex Have ever thought to live, just a trace has been made.

When a new dinosaur museum in Japan – set to open in Nagasaki in October 2021 – began pulling together its collection, it could wait to try and get a hand on an actual skeleton. However, the chances of this disappearing are small. Luckily, Nagasaki became a twin with Leiden. As a result, the team behind the Nagasaki Museum arrived in Naturalis to ask if they would be ready to produce a 3D reproduction of Tricks to sit in pride of place at the new site. The Naturalis team said they would.

“It was quite a challenge, but we were very happy to accept it,” Hensack Jacobs, Dynasource’s project manager at Naturalis, told Digital Trends.

The reinvention of Trix was made a little easier by some previous work done by paleontologists who discovered skeletons in 2013. As a way to preserve it, the team had 3D-scanned several bones at high resolution. This collection of bones was augmented with new scans of certain parts – such as the bones of the foot, jaw, and skull – by anatomist Pasha van Bijlert. The scanning process was performed using various Artech laser scanners, including Artech EVA, Artech Spyder and Artech Leo. On a computer, the Naturalis team manipulated the skeleton so that it appears in the “attack” of the Nagasaki Museum.

However, producing a digital copy of one T rex The skeleton was only a phase of the process. This is the difference between Apple CEO Tim Cook holding a CAD drawing of the next iPhone and a customer holding the finished product in his hand. Printing was another ball game.

“Full printing T rex Is the work of a demon. “It took nearly a year for two huge builder Extreme 3D printers and eight Ultimaker 2+ printers to print all 320-plus bones. Some of the bones were still large enough to fit perfectly in the printer, so they were cut digitally to fit. “

The process of printing bones using PLA was a time-consuming stress headache. “Some prints took about two weeks to expire,” she continued. “Because the office was closed during the weekend due to COVID, it can be quite nervous to leave and have to keep an eye on everything on Monday.”

Once printing was complete, it was on to the next stage of the process. For one thing, the pieces had to be painted: a process done by hand to color appropriately aged the white 3D-printed material. Because the “bones” had to be shipped to Japan, the researchers did not collect the fully prepared skeletons. However, he glued hundreds of different prints together into 50 different pieces, which could then be joined together. Each of these sections was to be mounted on steel frame parts, which would fold up like a giant Lego set.

The biggest challenge, Jacobs said, was time. “It had never been done before,” he said. “We did not know if the calculations were correct and how long all this would take, especially in the post-print processing and production of frames. Luckily we had a very efficient team that was very flexible and good at troubleshooting. “

Finally, the project was completed and the Twin of Tricks was sent to Japan. It will now be installed in its new home ready for the opening of the Dinosaur Museum on 29 October.

This can also be a good thing when it comes to the sale of Dino skeletons. According to paleontologists, the idea of ​​fossils becoming curios in the fourth living room of some billionaires is a tragedy. This means losing access to a sample that can help advance growing global research in this area.

“Here it is [a possibility], ”Said Jacobs. Unfortunately, she said, perhaps not the full scale that her team did. ((or,) [if you really do want that,] You have to talk to our CEO, “That laugh.”

But corporate retreats Jurassic Park When the original version of the park went horribly wrong, it did not give up and a swarm of people died as a result. They came back – in the story, at least – together Jurassic World. In other words, these things are about persistence. And, in this case, the agreement.

“If you have a 3D printer yourself, you can take your own cat-shaped print T rex Jacob said Naturalis offers online through the manual. “A 3D-print is also available to us triceratops

It will not break even the bank. “It’ll take you around a roll of filament, some glue, and some patience I’ll say,” she said.
