    Tato bakalářská práce se zabývá výrobou součásti pomocí metody Fused deposition modeling a ekonomickým porovnáním této výroby s jinými výrobními technologiemi. Danou součástí je příslušenství ručního kuchyňského robota, které je vinou špatného upínacího průměru nepoužitelné. V programu Autodesk Inventor byl vytvořen model, který je, s výjimkou pozměněných funkčních rozměrů, totožný s původní součástí. Finální příslušenství šlehače bylo vyrobeno metodou Fused Deposition Modeling na zařízení uPrint.This bachelor thesis deals with the production of component using the Fused Deposition Modeling method and economic comparison of this production to other manufacturing technologies. This component is accessory of manual food processor, which is due to poor clamping diameter unusable. In Autodesk Inventor model was created, that is, with the exception of altered functional dimensions, identical to the original parts. The final accessory of beater was made by using the Fused Deposition Modeling method with uPrint equipment.

    Poly(ϵ-caprolactone) and poly(ethylene glycol) based magnetic nanocomposite scaffolds were fabricated using fused deposition modeling and stereolithography approaches, and a hybrid scaffold was obtained by combining these additive manufacturing technologies. Viscoelastic properties in compression were investigated at 37 °C, spanning a range frequency of four decades. Results suggest that poly(ϵ-caprolactone) and poly(ethylene glycol) based scaffolds adequately reproduce viscoelastic properties of subchondral bone and articular cartilage tissues, respectively. By combining fused deposition modeling and stereolithography it is possible to manufacture a hybrid scaffold suitable for osteochondral tissue regeneration.

    3D printing technology is a leading technology for producing 3D virtual shape product. It is getting more popular by its accuracy and three dimensional objects. The objective of thesis work is to present a technology review on additive manufacturing processes and to produce prototypes of human spare parts such as organs by using 3D printer. Fused deposition modeling additive manufacturing process is used for prototyping of human organs. Human organs are designed by solid modeling software. Thermoplastic polymer materials like polylactic acid, acrylonitrile butadiene styrene and nylon are used in this process. The Author concludes that fused deposition modeling additive manufacturing process can be simplified by bio printer additive manufacturing process. Human living cell and biomaterial can be used as a material in this process. Organs can be designed by solid modeling software. The scheme is to explore 3D printing technology for producing human artificial organs for saving thousands lives. Further experiment is necessary for functional and clinical use of printed organs
