A startup compnay focusing on medical implants made by new printable bio-materials through novel 3D printing processing

• Designed and constructed gas-protected metal casting and hot extrusion system• Developed patented bioabsorbable Zinc alloys which obtained ultimate strength of 360 MPa and suitable bio-degradation profile for coronary stent application• Produced miniature Zinc alloy tubes with diameter of 3 mm and wall thickness of 0.15 mm by adapting rotary swaging and hot-rolling process• Assessed In-Vitro and In-Vivo bio-corrosion and toxicity of Zinc alloys through immersion, cell culture, and animal (rat and rabbit) tests according to ISO 10993

Project #1: Bioabsorbable Metallic Medical Implants• Designed and constructed high temperature ultrasonication dispersion platform and high pressure metal powder compressing die set• Incorporated nano-particles which boosted strength, ductility, and corrosion resistance of Magnesium with patented ultrasonication dispersion technology• Designed pseudo-physiological test bench specific for the development of bioabsorbable metallic materialsProject #2: Vascularized Hydrogel Liver Scaffolds• Conducted CAD design and created a hierarchical biomimetic model of liver vascular structure based on bionics and numerical simulation• Developed novel polymer-scaffold fabrication process by combining 3D printing, transfer-molding and freeze-drying to produce porous scaffold with complex internal vascular structures• Invented 3D perfusion device for dynamic cell culture which increased liver-cell viability by 63%

• Arranged lab resource, visitor reception and lab safety preparation• Trained graduate students and summer students on bioabsorbable metallic material research methods

Built a high-performance student volunteer team and assisted organizing the 10th Annual Conference with 300 attendees
