Car component quality testing technology helps hip surgeons ensure prostheses bind to bones

Hip surgeons are making significant advances in designing hip replacement components using additive manufacturing (3D printing) but have been struggling to devise easy methods of testing the designs they have created without using destructive testing techniques. Now researchers in WMG at the University of Warwick have devised a way of examining and ensuring the quality of those designs without destructive testing using scanning techniques normally used to examine new component designs for high-end automotive manufacturing.Professor Mark Williams

Successful surgical reconstruction or replacement of a joint (arthroplasty) requires integration of the prosthetic implant with the bone to replace the damaged joint. Surgeons therefore seek to use Bone-mimetic biomaterials for implants as their mechanical properties and porous structure can be designed to allow bone ingrowth and help fix the implant.

Dodo’s violent death revealed

The famous Oxford Dodo died after being shot, according to breakthrough research by Oxford University Museum of Natural History and WMG at the University of Warwick.

Using revolutionary forensic scanning technology and world-class expertise, researchers have discovered surprising evidence that the Oxford Dodo was shot in the neck and back of the head with a shotgun.

The significant and unexpected findings, made by Professor Paul Smith, director of the Museum of Natural History, and Professor Mark Williams from WMG at the University of Warwick, only became apparent when mysterious particles were found in the specimen during scans carried out to help analyse its anatomy.

Dodo remainsSubsequent analysis of the material and size of the particles revealed that they are lead shot pellets, typically used to hunt wildfowl during the 17th century.

The findings cast doubt on the popular theory that the Oxford Dodo is the remains of a bird kept alive in a townhouse in 17th-century London.

Queen’s wedding cake resurrected with scanning tech for 70th Anniversary

Queen’s wedding cake resurrected with scanning tech for 70th Anniversary Cutting-edge technology has brought Queen Elizabeth II’s wedding cake back to life in time for hers and Prince Philip’s 70th anniversary, thanks to research by WMG at the University of Warwick.

Professor Mark Williams at WMG, alongside the British Sugarcraft Guild (BSG), employed 3D scanning technology to recreate a full-sized replica of a cake presented to the royal couple on their wedding day in November 1947 – which was almost totally destroyed by vandals in 2015.

The technology was able to accurately scan the cake to within 0.1mm and reproduce a high-resolution 3D model that was then be used to digitally repair the cake.

Analysing the surviving parts of the cake – an intricate 6ft ensemble, consisting of 6 tiers – Professor Williams was able to discover exactly how it was formed, and to determine precisely how to restore its original grandeur.

There were elaborate pictorial panels on each tier of the cake, the moulds of which had been lost through the decades. However, WMG’s engineering technology recreated these images from the wedding cake, and produced new silicone moulds through 3D scanning.

Oldest known marine navigation tool revealed with scanning technology

Details of the oldest known marine navigation tool, discovered in a shipwreck, have been revealed thanks to state-of-the-art scanning technology at WMG, University of Warwick.

Professor Mark WilliamsProfessor Mark Williams was tasked with scanning the artefact – an astrolabe from the late fifteenth century, used by mariners to measure the altitude of the sun during voyages – which was excavated in 2014 by Blue Water Recovery.

When the team found the object, no markings were visible – they believed it was an astrolabe, but they could not see any navigational Astrolabemarkings on it.

They then approached Professor Williams, who conducts pioneering scanning analyses in his laboratory at WMG, to reveal the artefact’s invisible details.

The scans showed etches around the edge of the object, each separated by five degrees – proving that it is an astrolabe.

These markings would have allowed mariners to measure the height of the sun above the horizon at noon to determine their location so they could find their way on the high seas.

World's 'first named dinosaur' reveals new teeth with scanning tech

Professor Mark Williams at WMG has revealed five previously unseen teeth in the jawbone of the Megalosaurus – and that historical repairs on the fossil may have been less extensive than previously thought.

Sophisticated engineering scanning tech helps archaeologists identify rare ‘ghost coin’

IndioSophisticated CT scanning technology normally used by researchers from WMG at the University of Warwick to assist high tech manufacturing, has helped uncover the existence of a rare silver coin called an ‘Indio’ discovered by archaeologists investigating a shipwreck off the coast of Oman.

Over 2,800 artefacts were found in the wreck, including a bronze bell with an inscription dating back to 1498, gold coins from the era and an important bronze disc embossed with the "esfera armilar" — a personal emblem of Dom Manuel I, the then-king of Portugal.

Warwick Researchers Help Reconstructing the Michelangelo Bronzes

En3D Digital Modelgineers and imagers from the University of Warwick’s WMG and anatomists from Warwick Medical School at the University of Warwick are helping art historians from the University of Cambridge have been working together to try to understand how the two mysterious Renaissance bronzes were made and why they look the way they do by making accurate replicas of the originals. The latest technology-neutron imaging, XRF analysis, 360 degree laser scanning, 3D printing, and real-time x-ray videography - has been involved in this Renaissance ‘whodunnit’.
