Semisolid Extrusion Printing and 3D Bioprinting

This chapter provides an insightful overview of two transformative technologies in the realm of additive manufacturing: semisolid extrusion printing (SEP) and 3D bioprinting. Semisolid extrusion printing, a novel technique, has emerged as a promising approach for fabricating complex structures with intricate geometries using viscoelastic materials. On the other hand, 3D bioprinting revolutionizes tissue engineering and regenerative medicine by enabling the precise deposition of living cells and biomaterials to fabricate functional constructs. This review delves into the principles, advantages, and challenges associated with both technologies, exploring their applications in diverse fields, including pharmaceuticals, medical devices, and tissue engineering. By addressing critical aspects such as material selection, process optimization, and regulatory considerations, this chapter illuminates the significant contributions of semisolid extrusion printing and 3D bioprinting outlining the evolution of additive manufacturing and its profound impact on healthcare and biotechnology.
