Abstract

3D tisak klasificiran je kao aditivna, bazirana na prahu, solid freeform fabrication tehnika.

Istraživana metoda može se tako�er smatrati novom i propulzivnom vrstom digitalnog tiska

koja proizvodi trodimenzionalne objekte (“otiske“). Tehnika se temelji na konvencionalnom

ink jet tisku, koristeci materijal u obliku praha umjesto tiskovne podloge i tekuce vezivo kao

tiskovnu boju.

Svojstva materijala za 3D tisak samo su periodicno istraživana sa gledišta standardne

graficke tehnologije. Stoga, teza nudi cjelovitu studiju svojstava osnovnih materijala i samih

otisaka, koristeci postojece i modificirane metode karakterizacije koje se koriste u grafickoj

industriji, strojarstvu i ostalim srodnim industrijama. Istraživanje objašnjava raznolika

svojstva materijala za 3D tisak i 3D otisaka, ukljucujuci strukturna svojstva, reprodukciju

boje, postojanost boje, utjecaje ubrzanog starenja, mehanicka svojstva, te nudi opcenite

modele istraživanja i definira metodologiju.

Cilj teze je karakterizacija strukture i definicija trajnosti i stabilnosti materijala i otisaka u 3D

tisku upotrebom odabranih mikroskopskih metoda, spektrofotometrijskih metoda, metoda

slikovne analize, metoda za evaluaciju površinske strukture, metoda mehanickog ispitivanja

te metoda za starenje i odre�ivanje postojanosti materijala. U evaluaciji i karakterizaciji

korištena su prikupljena i novo stecena znanja tijekom interdisciplinarnog istraživanja, te su

diskutirana optimalna rješenja i metode.

Rezultati teze su specificno u slijedecem, verifikaciji odabranih metoda za karakterizaciju

kao pogodnih za istraživanje svojstava materijala i otiska u 3D tisku; definiciji metoda i

procedura ispitivanja strukturnih, površinskih i kolorimetrijskih svojstava, te svojstava

postojanosti i stabilnosti boje 3D otisaka; doprinos razvoju metodologije za valorizaciju

postojanosti 3D otisaka, s naglaskom na postojanost prema svjetlu u uvjetima ubrzanog i

prirodnog starenja; sistematski prikaz i analiza kvantitativnih i kvalitativnih podataka vezano

uz specificna svojstva 3D otisaka.

Abstract (english)

3D printing is classified as an additive, powder-based, solid freeform fabrication technique.

The method researched can be also regarded as a novel and propulsive form of digital

printing, creating finished objects in three dimensions. It is based on conventional ink jet

technology, using powder material instead of a substrate and liquid binder, clear or coloured,

as an ink.

As 3D printing materials and 3D prints properties have been only periodically researched

from the view of standard graphic technology, the thesis offers a comprehensive study using

the existing and customized characterization methods usually employed in the graphic and

material science and other related industries. The work explains the variety of characteristics

of 3D materials and prints, including the structure, colour reproduction and methodology,

permanence and colour stability, effects of accelerated aging and mechanical properties, as

well as provides the general research models and defines the methodology.

The goal of the research was to characterize the structure and to define permanence and

stability of 3D printing materials and prints by applying selected microscopic,

spectrophotometric methods, image analysis methods, surface evaluation methods,

mechanical testing and permanence testing methods. These were performed with compiled

existing and newly acquired knowledge during the interdisciplinary research and optimal

solutions and methods were discussed.

The thesis outcomes are specifically in the following, verification of the selected

characterization methods as suitable for 3D printing materials and prints properties research;

definition of methods and procedures, for research of 3D prints structure, surface,

colorimetric and colour stability characteristics; contribution to the development of

methodology for valorisation of 3D prints colour permanence, with emphasis on light

fastness of 3D prints under natural and accelerated aging conditions; systematic presentation

and analysis of quantitative and qualitative data regarding the 3D prints specific properties.
