Our next article in theState of Resin 3D Printingseries contains insights from a scientist with a deep understanding of additive manufacturing and material science.
Joanna Ortyl教授，博士，DSC。，Eng。Ortyl应用研究团队克拉科夫大学的技术。我的项目nclude Opus, looking at carbon dots and applications in photopolymerisation, and the development of a 3D printer to work with nanocomposites. Research spans bioprinting of hydrogels, cationic and free-radical photoinitiators to 3D-vat printing.

3DPI：您认为要克服基于光聚合物的3D打印的下一个技术障碍是什么？
Joanna Ortyl: The next technological hurdles that photopolymer-based 3D-VAT printing technology must overcome are primarily the ability to print integrated circuits and electronics. For example, to obtain highly conductive materials combined with insulators. Maybe even 3D printing and combining semiconductors with conductors and insulators in the future. Moreover, all this while maintaining the precision and resolution of 3D printing at 1um or below. Another technologically important issue is the possibility of 3D printing magnetic materials that could be positioned by a magnetic field. In the future, one might be tempted to 3D print from micromotor photopolymers. Imagine – a small rotor rotating in an external magnetic field, obtained by 3D printing.
3DPI：您认为哪些增值税光聚合的应用是市场不足的，为什么？
Joanna Ortyl: I consider a photo-curable composite or nanocomposite resins to be particularly underdeveloped by the current market. 3D printing of composite materials offers excellent opportunities, but it is not easy to obtain a working material that exhibits an ordering of the filler, such as fibres aligned in one direction.
我在3D打印中看到了光聚合技术，尤其是在获得导电材料时。在这种情况下，有必要将光的感知扩大为光聚合过程的来源，而不仅限于可见光谱的范围，而且还限于NIR范围。将光谱的功能扩展到NIR范围，例如980 nm，有可能将全新的材料用于引发器系统的角色。此外，LED光源不应受到限制，但是应考虑电子和光学方面的新技术解决方案。
3DPI：关于增值税光聚合技术的材料开发的机会在哪里？
乔安娜Ortyl: Photopolymerisation在3 d技术printing allows you to freely modify the composition of the raw material from which we print, to the extent that is not possible with other 3D printing techniques that use thermal processing of materials (FDM, SLS printing). The photopolymerization technique allows processing materials at temperatures close to room temperature, making it possible to modify photo-curable resins by adding temperature-sensitive components that would thermally decompose in standard 3D printing techniques (FDM, SLS). Thus, using the photopolymerization technique, it is possible to introduce materials for 3D printing that are not suitable for use in other techniques such as FDM SLS. Moreover, due to the nature of energy transport in the form of light, the use of photopolymerization allows the use of 3D printing devices in different media such as vacuum, or water environments, where the use of classical 3D printing techniques FDM or SLS is not possible due to the transfer of energy in these techniques in the form of thermal energy.
