20.500.12556/RUL-148958 Uporaba 3D tiskanja za izdelavo livarskih peščenih form Application of 3D printing for manufacturing sand casting forms Cilj diplomskega dela je bil zasnovati in izdelati valj dvotaktnega motorja iz aluminijeve litine s pomočjo tridimenzionalnega tiskanja. V modelirniku smo zasnovali valj in ga prilagodili za namen litja. Na podlagi zasnove v modelirniku smo natisnili modele in jedrnike z uporabo tridimenzionalnega tiskalnika ter z njimi izdelali peščeno formo, v katero smo vlili aluminijevo litino. Ulitek smo dodatno mehansko obdelali in ga uporabili na motornem sklopu. Ugotovili smo dejansko praktičnost in hitrost izdelave livarskih peščenih form z uporabo tridimenzionalnega tiskanja. Tekom procesa izdelave smo odpravili storjene napake, optimizirali zasnovo v modelirniku in s hitrim prototipiranjem uvedli tehnične izboljšave v peščeno formo za izdelavo čim bolj dovršenega izdelka. The objective of final thesis was to design and manufacture a two-stroke cylinder from aluminium metal with the use of three-dimensional printing. With the use of modelling software, a model cylinder was designed and modified for casting. Based on the design in the modelling software, patterns were printed via three-dimensional printing and used for the construction of a sand-casting mould, which was then used for casting aluminium metal. Additionally, the casted cylinder was machined and used on the engine assembly. The practicality and speed of sand-casting mould production using three-dimensional printing was established. During the manufacturing process, previous errors were mitigated, the design in modelling software was optimized and with rapid prototyping technical improvements were introduced into the sand-casting mould to produce a perfected final product. 3D tiskanje livarski model litje v pesek hitro prototipiranje 3D print casting pattern sand casting rapid prototyping true false false [K.
