Abstract
Diplomsko delo vsebuje pregled tehnologije dodajalne izdelave ter se podrobneje osredotoči na dodajalno izdelavo kovinskih izdelkov. Opisan je postopek, kjer smo s pomočjo postopka dodajalne izdelave na 3D tiskalniku (Markforged Metal X) natisnili različno oblikovane kovinske epruvete za natezni test iz nerjavnega jekla 17-4 PH. Dodajalni izdelavi je sledilo čiščenje in sintranje vzorcev 26 ur v atmosferi iz argona. Vzorce smo najprej pregledali vizualno, naredili analizo makro in mikro obrusov, merjenje trdote in natezne teste. Ugotovili smo, da na zapolnjenost volumna vzorca z materialom vpliva njegova oblika, kjer lahko načrt gibanja poti dodajalne glave povzroča nezadostno zapolnjevanje volumna. Na mehanske lastnosti vpliva predvsem oblika in velikost vzorčnih izdelkov, negativni vpliv pa kaže predvsem zapolnjenost volumna z materialom. Oblika epruvet nima vpliva na trdoto preizkušancev.

Title:Additive manufacturing of stainless steel with Markforged Metal X
Abstract:
The thesis contains an overview of additive manufacturing technology and focuses more on the additive production of metal products. The procedure is described, where we printed metal test tubes of various shapes for tensile testing from stainless steel 17-4 PH using the additive manufacturing process on a 3D printer (Markforged Metal X). Additive manufacturing was followed by cleaning and sintering the samples for 26 hours in an argon atmosphere. The samples were first visually inspected, macro and micro abrasions were analyzed, hardness and tensile tests were measured. We found that the filling of the sample volume with material affects its shape, where the plan of the path of the additive head can cause insufficient filling of the volume. The mechanical properties are mainly affected by the shape and size of the sample products, and the negative impact is mainly shown by the filling of the volume with material. The shape of the test tubes does not affect the hardness of the test pieces.

Keywords:additive manufacturing, metal printing, tensile test, microstructure analysis, fractures analysis, stainless steel 17-4 PH
