Streszczenie

Praca przedstawia opis stanowiska badawczego do bezdotykowego pomiaru geometrii powierzchni, uzyskanych w trakcie nakładania kolejnych warstw druku 3D metodą MEX. Stanowisko bazowało na 6-osiowym, hybrydowym centrum obróbkowym wyposażonym w głowicę drukującą, laser pomiarowy oraz kamerę termowizyjną. Badania wykonano dla różnych rozmiarów dysz głowicy drukującej, szybkości nakładania ścieżki oraz strategii budowy kolejnych warstw. Uzyskane wyniki pomiarów pozwalają lepiej zrozumieć procesy formowania powierzchni zewnętrznych drukowanych części i mogą być podstawą do budowy dokładniejszych modeli predykcyjnych w wytwarzaniu przyrostowym. Możliwość realizacji druku 3D na obrabiarce wieloosiowej otwiera nowe obszary badań i potencjalnie, nowe perspektywy optymalizacji strukturalnej i parametrycznej operacji druku 3D.

Laser Measurement of 3D Printing Path Geometry

Abstract

The study presents a description of a research setup designed for non-contact measurement of surface geometry formed during the deposition of successive layers in MEX 3D printing. The setup was based on a six-axis hybrid machining center equipped with a printing head, a laser sensor, and a thermal imaging camera. The experiments were conducted for various nozzle sizes of the printing head, different path-deposition speeds, and multiple layer-construction strategies. The obtained measurement results provide a deeper understanding of the mechanisms governing the formation of outer surfaces in printed parts and may serve as a basis for developing more accurate predictive models in additive manufacturing. The capability to perform 3D printing on a multi-axis machine tool opens new areas of research and, potentially, new opportunities for structural and parametric optimization of 3D printing processes.
