Dear Colleagues

We have witnessed more and more medical-related applications that 3D printing has made possible. Personalized implants, hearing aids and other medical products utilize the benefits of 3D printing and are already in commercial use. Many utilize different 3D printing processes and material combinations and have links to design and medical imaging. ISO/ASTM standards categorize 3D printing processes into seven categories based on the process's fundamentals. Inside these categories, different devices work similarly but with different principles. Development of the processes and new materials offers all the time new possibilities for new applications, which were not possible before.

This special issue seeks submissions related to medical 3D printing and focuses on new applications and the role of different 3D printing processes in these applications.
