Mehanske lastnosti 3D tiskanega izdelka iz materiala PLA : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoKavčič, Žan, strojnik3D-tisk je proces izdelave izdelka, plast za plastjo. Obsega različne tehnologije. V zaključni nalogi smo se osredotočili na metodo ciljnega nalaganja. Zanimalo nas je, kako stopnja notranje ... zapolnitve vpliva na mehanske lastnosti izdelka iz materiala PLA. Po standardih za polimerne materiale smo natisnili preizkušance ter nato naredili test na napravah za upogibni in udarni preizkus. Udarno žilavost smo izračunali iz razmerja udarnega dela in površine preseka vzorca na mestu preloma. Pri upogibnem preizkusu smo merili silo in izračunali upogibno napetost. Ugotovitve so bile, da je material PLA krhek. Mehanske lastnosti se višajo z večanjem stopnje zapolnjenosti. Pri manj obremenjenih delih bi zato uporabili minimalne stopnje zapolnitev, medtem ko bi za bolj obremenjene predele uporabili najvišjo stopnjo zapolnitve.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
