This study is aimed at applying existing calculation methods for pressure-loaded parts to additively manufactured pipe structures, considering the two materials EN AC-43000 (3.2381, AlSi10Mg) and AISI 316L (1.4404, X2CrNiMo17-12-2). For this purpose, systematic tensile tests are carried out for both materials. In addition, a statistical evaluation is performed to determine the design-relevant strength characteristics with a survival probability Ps of 97.5 % for both materials in the as-built and heat-treated condition.\r\nPipe specimens are manufactured, half of which are heat treated, geometrically measured and then subjected to a burst pressure test to experimentally determine the failure-critical internal pressure. These results are compared with calculated burst pressures. The calculations are based on the application-relevant methods identified in this study, considering the strength values determined for the respective material condition. This comparison is used to assess the suitability of the calculation methods for additively manufactured pipe structures, based on the materials investigated.","lang":"eng"}],"publication":"International Journal of Pressure Vessels and Piping","title":"Analytical and experimental determination of the failure-critical pressure of pipe structures manufactured by PBF-LB/M","publisher":"Elsevier BV","date_created":"2026-01-07T08:39:04Z","year":"2026","quality_controlled":"1","article_number":"105753","_id":"63512","department":[{"_id":"146"},{"_id":"9"},{"_id":"624"},{"_id":"149"},{"_id":"321"}],"user_id":"97759","status":"public","type":"journal_article","doi":"10.1016/j.ijpvp.2026.105753","main_file_link":[{"url":"https://doi.org/10.1016/j.ijpvp.2026.105753","open_access":"1"}],"oa":"1","date_updated":"2026-01-14T11:56:01Z","author":[{"id":"38077","full_name":"Koers, Thorsten","last_name":"Koers","first_name":"Thorsten"},{"last_name":"Magyar","id":"97759","full_name":"Magyar, Balázs","first_name":"Balázs"},{"id":"93904","full_name":"Bödger, Christian","last_name":"Bödger","first_name":"Christian"},{"first_name":"Thomas","id":"553","full_name":"Tröster, Thomas","last_name":"Tröster"}],"citation":{"ama":"Koers T, Magyar B, Bödger C, Tröster T.

One disadvantage of FDM is the shrinkage of the components during the manufacturing process. The filament is molten in the nozzle, deposited layer by layer, and cools down again. During solidification, the filament shrinks inhomogeneously in the x/y/z direction, which leads to distortion of the component geometries. Particularly with higher nominal lengths and complex local geometries, there is a need for optimization with regard to dimensional accuracy. The aim of this paper is to counteract this on the software side with global as well as local shrinkage factors. The expected shrinkage within a layer is predicted with an in-house developed software. The geometric accuracy of the model is verified by experimental investigations on cylindrical test specimens. In these, the so-called clover effect occurs as a result of the shrinkage. The circular shape of the deposited layer is deformed by the distortion in the x–y plane comparable to a clover. Finally, the results are validated by analyzing a demonstrator in the form of a bracket."}],"publication":"Macromolecular Symposia","language":[{"iso":"eng"}],"intvolume":"       411","citation":{"ama":"Koers T, Magyar B.

As a result a possible drawing entry of support structures was developed.
