Shanghai researchers develop 3D printed fracture fixing glass

November 3, 2016

  • Bioglass is a material made of calcium and phosphate salt. It is used in medicine and dentistry to bond defects found in bones and tooth enamel. Though bioglass bonding is highly effective, its fusion in larger bone defects has room for improvement. A team of researchers from Shanghai Jiaotong University and the University of Shanghai for Science and Technology in China have proposed a possible solution, by combining mesoporous bioactive glass (MBG) with C3S, one of the main materials found in common Portland cement, and 3D printing a result. Their findings were recently published under the title Three-dimensional printing of tricalcium silicate/mesoporous bioactive glass cement scaffolds for bone regeneration in the Journal of Materials Chemistry B from the Royal Society of Chemistry.

Chinese doctors successfully implant a 15cm long 3D printed titanium vertebrae prosthetic

Aug 29, 2016

  • A team of doctors from China’s Shanghai Changzheng Hospital have successfully implanted a 15 centimeter long 3D printed titanium vertebrae prosthetic into a patient suffering from a serious case of cervical chordoma. The patient, 40-year-old Ms. Zhou from HuNan province, had been suffering from the debilitating disease for nearly 7 years and had just about given up on life until 3D printing presented an almost miraculous treatment option. During the course of her disease, Ms. Zhou underwent a number of surgeries which proved ultimately unsuccessful, as the tumor located on her upper spinal cord and neck kept returning. The malignant tumor itself, which had grown to envelop the length of six vertebrae, was causing a number of problems, including severe compression of the trachea and esophagus, which made breathing and eating two very difficult tasks for the patient.

China aims for 3D skin printing technology

August 5, 2016

  • CHINESE researchers and companies are developing the technology and processes to make 3D-printed skin a reality. They expect to achieve this within two to three years. Wu Jun, director of the Burns Institute at the Southwest Hospital in Chongqing, said he has been testing the process with pig skin. “In printing skin, the biggest challenge is the ‘ink.’ We need to find the right material that can be made into a certain form while not damaging its activity,” he said. The ink he refers to is the skin tissue. 3D printing in the medical industry mostly produces hard items, the flexibility of skin makes this process more difficult.

Chinese-made All-in-One 3D Metal Printing Technology being used in China’s Stealth Jet Fighters

Jul 24, 2016

  • The first-of-its-kind device, the Micro Forging & Casting Sync Composite Device, uses a technology perfected in China called “smart micro casting and forging.” The technology combines metal casting and forging technology to significantly improve the strength and ductility of metal molds, thereby expanding their service lives and reliability. Combining 3D printing, casting and forging also contributes to stronger parts and added toughness; improved product lifecycles and better reliability, according to the inventors. The team said its casting and forging process is being used to create titanium 3D printed joints for a new Chinese fighter — likely the J-20 — which has entered limited production. These joints would have been impossible to create as a single piece using any subtractive manufacturing technique.

Chinese Construction Company 3D Prints an Entire Two-Story House On-Site in 45 Days

Jun 16, 2016

  • Beijing-based HuaShang Tengda is a major competitor of fellow Chinese construction company WinSun, which we’ve followed in the past since they surprised us with their 3D printed homes, including a six-story apartment building and a mansion. Not long after that, WinSun’s reputation was tarnished by quite of bit of controversy when Dr. Berokh Khoshnevis, creator of the revolutionary Contour Crafting technique of 3D printing buildings, stated that the Shanghai company had blatantly stolen his patented technology and were passing it off as their own. Moreover, Dr. Khoshnevis said, WinSun’s claim that they were 3D printing entire homes was untrue; in fact, they were 3D printing small sections of walls and then cobbling them together on-site using other construction methods.
