Optimizacija 3D tiskanega veznika za stol : diplomsko delo = Optimisation of a 3D printed chair connector : B. Sc. thesisCvetko, MetodV diplomski nalogi smo preučevali različne verzije 3D tiskanega veznika za stol za domačo rabo. Namen raziskave je bilo nadomestiti originalni kovinski veznik, ki povezuje štiri noge in sedišče ... stola, s 3D tiskanim veznikom in s tem zmanjšati maso. Pri izdelavi veznika smo želeli uporabiti lesno-plastični kompozit ter s 3D tiskanjem izdelati oblikovno zanimivejši detajl stola. Veznik je bil po originalu modeliran v programu SolidWorks, v katerem so bile narejene tudi simulacije obremenitev. Simulacije so pokazale deformacije in napetosti na vezniku, hkrati pa območja, potrebna ojačitve. Uporabili smo tudi študijo topologije, katere namen je zmanjšati maso izdelka, vendar kljub temu ohraniti trdnost celotnega izdelka, in zmanjšanje deformacij, ki se pojavijo ob delovanju obremenitev. Ojačan model smo s pomočjo študije topologije optimizirali in preoblikovali. Optimizirana 3D tiskana veznika smo natisnili iz polilaktične kisline (PLA) in lesno-plastičnega kompozita ter testirali v Laboratoriju za preizkušanje pohištva po zahtevi standarda SIST EN 12520:2010. Optimiziran 3D tiskan veznik, narejen iz PLA materiala, je zahtevi standarda zadostil, veznik, narejen iz lesno-plastičnega kompozita, pa ni ustrezal, saj je prišlo do loma. Ugotovili smo, da je s simulacijami v programu SolidWorks mogoče dokaj natančno modelirati model, ki bo zadostili zahtevam standarda. S študijo topologije in natančnim poznavanjem lastnosti materialov je mogoče veznik optimizirati ter zmanjšati maso, ne da bi zmanjšali njegove mehanske lastnosti.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
