In addition, many new biodegradable resins have been developed and the effectiveness of the scaffold produced by vat polymerization has recently been demonstrated in vivo. CONCLUSION From an engineering viewpoint, the possibilities for vat polymerization use continue to expand. For future applications, new photopolymers, a mix- ture of other targeted materials, and related processes must be developed. The trade-off between mechanical strength and heat resistance character- istics should also be solved. Application developments should take advantage of two of the most important characteristics of vat polymerization: highprecision and transparency. Vat polymerization offers a sophisticated approach to fabricating both medical devices and drug delivery systems. ~AM&P This article is excerpted from H. Kanematsu, D.M. Barry, R. Noorani, and P.
