Abstract

V magistrskem delu smo z identifikacijo fizikalno kemijskih procesov in pojavov tako med vrstičnim nalaganjem kontinuirnih valjev s tvorbo slojev, kot pri ohlajanju 3D tiskanih slojev, dokazali, da je na osnovi poznavanja razvoja mikrostrukture 3D tiskanega polimernega kompozitnega materiala moč optimizirati procesne parametre in vplivati na fizikalno kemijske procese pri tvorbi in razvoju tiskanih slojev tako, da se dosežejo željena mikrostruktura in ciljne lastnosti izdelka. Z določitvijo narave interakcij med magnetnimi delci in polimerno matico v posameznih stadijih oblikovanja izdelka in ovrednotenjem vpliva parametrov 3D tiskanja na vrsto, porazdelitev in koncentracijo defektov ter na magnetne lastnosti tiskanih vzorcev plastomagnetov, smo postavili model mehanizma sinteze vrstic in slojev pri 3D tiskanju polimernih kompozitov s kovinsko utrjevalno fazo. Velja omeniti, da do časa objave magistrskega dela potencialne metode za direktno spremljanje kinetike in mehanizma kemijskih reakcij (FTIR spektroskopija) ter analizo strukturnih sprememb oziroma za In situ vizualizacijo razvoja mikrostrukture v materialih, še niso bile uporabljene pri eksperimentalnem študiju 3D tiskanja. Z izračunom točke stroškovne brezbrižnosti (ang. cost indifference) in primerjavo dveh tehnologij, 3D tiska ter injekcijskega brizganja, smo ugotovili, katera tehnologija je po izračunanem številu izdelanih magnetov, stroškovno učinkovitejša.

Secondary title:	Microstructure evolution during 3D printing of bonded magnets
Secondary abstract:	This Master's thesis identified the physicochemical processes and phenomena during in-line loading of continuous rollers with layer formation and the cooling of 3D printed layers. We have proved that knowing the microstructure development of 3D printed polymer composite material enables the optimization of process parameters and influences the physicochemical processes in the formation and development of printed layers to achieve the product's desired microstructure and properties. By determining the nature of the interactions between the magnetic particles and the polymer matrix at each stage of product formation and evaluating the influence of 3D printing parameters on the type, distribution, and concentration of defects and the magnetic properties of the printed plastic-magnet samples, we have established a model of the line and layer synthesis mechanism in 3D printing of polymer composites with a metal curing phase. It is worth mentioning that at the time of publication of this thesis, potential methods for direct monitoring of the kinetics and mechanism of chemical reactions (FTIR spectroscopy) and the analysis of structural changes or for in situ visualization of the microstructure evolution in materials have not yet been used for experimental study of 3D printing. By calculating the cost indifference point and comparing 3D printing and injection molding, we determined which technology is more cost-effective according to the calculated number of magnets produced.
