Abstract: The invention presents a patterning device (1) for the preparation of three-dimensional structures of a sample (S) comprising particles (P) free to migrate in a matrix (M). The device comprises a pattern generator (3) and a holder (2) connected to the pattern generator (3) on which is placed a sample (S). The patterning device (1) further comprises at least one transformation device (D) adapted for the transformation of the matrix (M) into a modified matrix (A/P) wherein the particles (P) are no longer free to migrate. The invention is also directed to a process for the production of a three-dimensional structure.

Abstract: A cartridge (1) for a 3D printer, wherein the cartridge (1) has a nozzle or is designed in such a way that a predefined nozzle can be formed in the cartridge (1). The cartridge (1) contains a dental composite material, and the dental composite material comprises a curable, in particular a light-hardenable, matrix and only fillers having a maximum particle size of <5 ?m. The dental composite material has a viscosity, in a non-cured state, in the range of 1 to 10,000 Pa*s, preferably 10 to 2,000 Pa*s, more preferably between 50 to 800 Pa*s.

Abstract: An electrospinning printing device and method thereof are disclosed. The device may comprise: a printing head arrangement configured to replaceably hold at least one printing head for discharging a fibrous material, and a collector arrangement configured to electrostatically attract material from the printing head, in which the collector arrangement may comprise an at least partially electrically insulated collector that is arranged to be connected to an electric power supply, and the at least one printing head is electrically grounded when held by the printing head arrangement.

Abstract: A cartridge for use in a tissue substitute printing system is disclosed, the cartridge may have: a material reservoir, the material reservoir storing a tissue substitute material in a flowable, in particular paste-like form; a material aperture arranged at a bottom side of the cartridge, the material aperture being fluidic coupled with the material reservoir for releasing tissue substitute material stored in the material reservoir; at least one auxiliary aperture arranged at the bottom side of the cartridge for releasing an auxiliary medium, the at least one auxiliary aperture being arranged in proximity to and fluidic separate from the material aperture. A tissue substitute printing system and a method for manufacturing a tissue substitute are also disclosed.
