- Item3D Printed Bionic Prosthetic Hands(IEEE, 2017) Koprnický Jan; Šafka Jiří; Najman PetrThis article deals with upper limb prosthetic made by 3D printing technology. For tests and analysis the number of open-source bionic hands (eNable and exiii’s HACKberry projects) were chosen. These hands represent low cost solution of conventional or myolectric prosthesis. Our investigation was focused on three main parts: 3D printing using different 3D printers, technologies and materials; assembly with the use of commonly gettable fasteners and devices on Czech market; functionality testing under laboratory condition. In conclusion our results of these fields are summarized and possible improvements are outlined.

- ItemComposite 3D printed scaffold with structured electrospun nanofibers promotes chondrocyte adhesion and infiltration(Taylor&Francis Online, 2018) Rampichova Michala; Kuželová Košťáková Eva; Filová Eva; Chvojka Jiří; Šafka Jiří; Pelcl Martin; Daňková, J.; Prosecka Eva; Buzgo Matej; Plencner Martin; Lukáš David; Amler EvženAdditive manufacturing, also called 3D printing, is an effective method for preparing scaffolds with defined structure and porosity. The disadvantage of the technique is the excessive smoothness of the printed fibers, which does not support cell adhesion. In the present study, a 3D printed scaffold was combined with electrospun classic or structured nanofibers to promote cell adhesion. Structured nanofibers were used to improve the infiltration of cells into the scaffold. Electrospun layers were connected to 3D printed fibers by gluing, thus enabling the fabrication of scaffolds with unlimited thickness. The composite 3D printed/nanofibrous scaffolds were seeded with primary chondrocytes and tested in vitro for cell adhesion, proliferation and differentiation. The experiment showed excellent cell infiltration, viability, and good cell proliferation. On the other hand, partial chondrocyte dedifferentiation was shown. Other materials supporting chondrogenic differentiation will be investigated in future studies.
