Abstract: Since 3D printing has developed into a highly available method throughout industry and research, numerous methods and techniques have emerged in life sciences. Especially in tissue engineering, several attempts of preparing sca olds for regenerative medicine have been made so far. The requirements for sca olds in tissue engineering, such as high porosity, appropriate pore sizes and a suitable range of mechanical properties have not yet met with 3D printing technique. Nano ber based sca olds have attracted a lot of attention because they can be tuned and tailor-made for the respective application. Nano ber based aerogels are extending the bene ts of nano ber sca olds into the 3rd dimension. They are prepared by freeze-casting methods and shown excellent properties regarding density, porosity and Young's modulus. Unfortunately, those structures always require a mold for shaping of the aerogel. We herein present a novel method for the layer-by-layer fabrication of nano ber structured aerogels. Starting from a commercially available 3D printer, a completely new hardware for the controlled deposition of nano ber suspensions was developed. 3D printing of those suspensions was nally facilitated by including a magnetic stirring system within the printing head as well as providing a cold print bed which is capable of keeping the surface temperature at - 50 °C.
