Pregled aditivnih tehnologij za obdelavo kovin in keramik ter njihove karakteristike

Rupnik, Andraž (author), Valentinčič, Joško (mentor), Lebar, Andrej (co-mentor)

Adiativne tehnologije predstavljajo široko področje tehnologij, ki se vedno bolj uveljavljajo v industriji. Uporabljajo se tako za izdelavo prototipov kot tudi končnih izdelkov. Ina izmed omejitev za večjo uporabo teh tehnologij v industriji je predvsem poznavanje zmožnosti teh tehnologij. V zaključni nalogi smo predstavili glavne tehnologije s področja 3D tiska kovin in keramik. Predstavili smo postopke selektivnega laserskega sintranja, selektivnega laserskega topljenja, topljenja z elektronskim žarkom, laserskega depozicijskega varjenja, depozicijskega varjenje z elektronskim žarkom, oblikovnega obločnega varjenja, nalaganja krojenih slojev, hladnega naprševanja in brizganja veziva. Za vsak postopek smo navedene glavne značilnosti, ter prednosti in slabosti. Naredili smo primerjavo med posameznimi postopki.

• Title: Overview of additive technologies for procesing of metal and ceramics and their characteristics

Abstract

Additive technologies represent a wide range of technologies that are increasingly gaining ground in the industry. They are used for both prototyping and manufacturing of finished products. One of the limitations for increasing the use of these technologies in industry is primarily knowing the capabilities of these technologies. The final thesis presents the main technologies in the field of 3D printing of metals and ceramics. The procedures of selective laser sintering, selective laser melting, electron beam melting, laser deposition welding, electron beam deposition welding, wire and arc additive manufacturing, ultrasonic consolidation, cold spraying and binder jet are presented. The main characteristics are given for each procedure. A comparison is made between individual procedures.
