Kenneth John Lacovara (born March 11, 1961) is an American paleontologist and geologist at Rowan University and fellow of the Explorers Club, [1] known for the discovery of the titanosaurian dinosaur Dreadnoughtus and his involvement in the discovery and naming of the giant sauropod dinosaur Paralititan, [2] [3] as well as his work applying 3D printing technology to paleontology.
The field of organ printing stemmed from research in the area of stereolithography, the basis for the practice of 3D printing that was invented in 1984. [5] In this early era of 3D printing, it was not possible to create lasting objects because of the material used for the printing process was not durable.
Different models of 3D printing tissue and organs. Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and ...
Replica made with a 3D printer. OH 24 (Olduvai Hominid No. 24, nicknamed "Twiggy") is a fossilized skull of the species Homo habilis. It was discovered in Olduvai Gorge, Tanzania by Peter Nzube in 1968. The skull was found crushed almost flat and was therefore named after the famously skinny model of the time Twiggy.
[2] [12] At the time of the auction, the fossil was mounted on a steel armature, and positioned in an attacking stance. [13] The missing bones were replaced by sculpted and 3D-printed replicas, [16] including mirrored versions of existing material. [8] The auction lot also included 3D scans of the fossil, with a license to use the scan data. [7]
3D printing is becoming an efficient way to produce artificial bones. First, a bone model is created by means of reconstruction of CAT scan images obtained from the patient. Then the artificial bone materials are used as "filament" for 3D printing. According to the resolution grafts, the 3D bone model would be divided into some layers.
