Additional seminar information – 3D printing or additive manufacturing (AM) is becoming important in clinical needs for on demand patient matched implants due to better functionalities, lower cost and shorter lead time to manufacture. Establishing process property relationships for different AM techniques are vital towards successful implementation of these manufacturing practices in biomedical devices. Additive manufacturing of multiple materials in single operation is also an exciting innovation. Hard biomaterials, e.g., calcium phosphate (CaP) ceramics being compositionally similar to the inorganic part of bone, are often used in bone implant applications, as both 3D printed tissue engineering scaffolds and surface modified hip and knee implant devices. We have used CaP scaffolds, fabricated using 3-D printing technology, for bone tissue engineering.  Dopant chemistry in CaP plays a vital role in controlling their resorption or degradation kinetics as scaffolds, mechanical strength, and biological properties of resorbable CaPs. 3D interconnected channels in CaP scaffolds provide pathways for micronutrients, improved cell-material interactions, and increased surface area allows improved mechanical interlocking between scaffolds and surrounding bone. Use of polymer helps in controlling drug release kinetics. In vivo studies show improved osteogenesis, angiogenesis and controlled drug delivery using natural medicinal compounds (NMCs) in these 3D printed scaffolds and coatings. These systems show promise for use in orthopedic and dental devices while eliminating the need for the autografts and the second site surgery for harvesting, as well as improving current hip / knee implant lifetime. The presentation will address design of next generation bone tissue engineering scaffolds and hip / knee devices based on clinical needs in fixation of bone disorders and scientific challenges

Susmita Bose, Ph.D. – Susmita Bose is the Herman and Brita Lindholm Endowed Chair Professor at the School of Mechanical and Materials Engineering, affiliate faculty of Department of Chemistry and Elson Floyd College of Medicine at Washington State University. Prof. Bose’s interdisciplinary research interest lies at the interface of Chemistry, Materials Science, Mechanical Engineering, Bioengineering and Biology, focusing on 3D printed bone scaffolds, implant materials and drug delivery vehicles.
