Fabrication of Ankle Foot Orthosis using digital technologies
Lasota, Marek ; Koutecký, Tomáš (referee) ; Koutný, Daniel (advisor)
This bachelor thesis presents a new way of an orthotic devices fabrication via digital technologies of 3D scanning, CAD modeling and rapid prototyping. First, as a part of an analysis of a present knowledge, is the usual way of an AFO fabrication described, including its disadvantages. Then the new method is outlined. Following, a thorough research of past works, which were already dealing with this subject, is done. In the second half of the thesis is the novel approach demonstrated in a development of an ankle-foot orthosis concept based on scanned data of a healthy subject‘s leg. In conclusion, an overall review and comparision of both fabrication processes is made.

Object reproduction with using 3D printing in the hyperbaric environment
Kadlec, Martin ; Vondrášek, David (advisor) ; Dvorský, Jaroslav (referee)
Title: Object reproduction by 3D printing in the hyperbaric environment. Objectives: The bachelor thesis is designed as pilot study examining "Object reproduction by 3D printing in the hyperbaric environment". Its aim is mainly to acquire sufficient knowledge as precursor to further research in this field. Methods: Data was organized into tables and charts (based on proprietary test results). Descriptive methods and inferential statistics (T-test) were used to determine hypothesis. Results: T-test did not determine a statistically significant difference in weight (p = 0.98026) between objects printed at atmospheric pressure (101,7 kPa ± 2 kPa) and objects printed at absolute pressure of 150 kPa ± 3,6 kPa. The weight difference of compared build sets was well within substantive significance threshold limit ≤ 5 %, <0,35 % - 4,37%>. All objects (build sets n1 = 10; n2 = 10) did meet the required criteria in proprietary functionality test, therefore we can assume that fairly affordable 3D printer will be capable of printing in hyperbaric environment ( ≥ 150kPa ± 3,6 kPa) and objects will be able to fulfill their main purpose as well. Even though the results are meaningful, further research is needed. Keywords: 3D printing, 3D digitization, hyperbaric environment, 3D printing in the unusual environment
