Compressive properties of cell structures manufactured by photo-curing technology liquid polymer resins – Polyjet Matrix

ABSTRACT: The article presents the results of compressive strength tests of cylindrical samples with a hexagonal cell structure. The samples were made of MED 610 material using the photo-curing technology liquid polymer resins. The compressive strength was estimated on the basis of a static compression test of the printed elements. It has been shown that the PolyJet Matrix 3D printing technology enables the printing models with a thin-walled cell structure, which, while maintaining the appropriate strength properties, can be used in the design and production of certain utility models.

KEYWORDS: 3D printing, PolyJet Matrix, compressive properties, cell structures

STRESZCZENIE: Przedstawiono wyniki badań wytrzymałości na ściskanie próbek cylindrycznych o heksagonalnej strukturze komórkowej. Próbki wykonano z materiału MED 610 z zastosowaniem techniki fotoutwardzania ciekłych żywic polimerowych. Wytrzymałość na ściskanie oszacowano na podstawie statycznego testu ściskania elementów drukowanych. Wykazano, że technologia druku PolyJet Matrix 3D umożliwia drukowanie modeli o cienkościennej strukturze komórkowej, co – pod warunkiem zachowania odpowiednich właściwości wytrzymałościowych – może być wykorzystane przy projektowaniu i produkcji niektórych wzorów użytkowych.

SŁOWA KLUCZOWE: druk 3D, PolyJet Matrix, właściwości ściskające, struktury komórkowe
