Abstract

Posljednjih godina u svijetu sve više raste ekološka osviještenost i na razne načine se

nastoji smanjiti zagađenje okoliša. Iz tog razloga sve više u uporabu ulaze biorazgradivi

materijali koji su s jedne strane ekološki prihvatljivi a s druge strane optimalni

kvalitetom. Cilj ovog diplomskog rada je ispitivanje uzoraka materijala koji su ekološki

prihvatljivi te izrada tiskovne forme od biorazgradivih materijala koja bi bila

primjenjiva za visoki tisak. Osnovni materijali uzoraka koji će biti korišteni su PLA

(polilaktidna kiselina) i PCL (polikaprolakton). PLA jedan je od najraširenijih

biorazgradivih polimera. Često se primjenjuje u medicini te je i rastući polimer u

proizvodnji ekološki prihvatljivih ambalažnih materijala. PCL je biorazgradivi polimer

sintetičkog porijekla. Razgradiv je u prirodi od strane bakterija i gljivica, ali nije

razgradiv unutar ljudskog ili životinjskog organizma radi nedostatka određenih enzima.

Uzorci materijala će biti pripremljeni u obliku filamenata za 3D tisak. Aditivna

proizvodnja je brz i jednostavan način izrade različitih modela, a u ovom diplomskom

radu će biti korištena za izradu tiskovne forme za visoki tisak. U eksperimentalnom

dijelu rada izrađene su pločice određenih dimenzija na kojima će biti provedena različita

mjerenja radi određivanja njihovih površinskih, strukturnih i mehaničkih svojstava s

ciljem karakterizacije odgovarajućeg materijala koji bi svojstvima odgovarao tiskovnih

formama koje se koriste u visokom tisku.

Abstract (english)

Over the last few years, environmental awareness has been growing in the world and

efforts are being made to reduce environmental pollution in various ways, which is why

biodegradable polymers are increasingly being used. It would be useful to find a

material that will be environmentally friendly, apart from its quality. The aim of this

thesis is to examine samples of materials that are environmentally friendly and to make

a printing form from biodegradable materials that would be applicable to letterpress

printing. The basic sample materials to be used are PLA (polylactic acid) and PCL

(polycaprolactone). PLA is one of the most widespread used biodegradable polymers

which is often used in medicine and is a growing polymer in the production of

environmentally friendly packaging materials. PCL is a biodegradable polymer of

synthetic origin. It is degradable in nature by bacteria and fungi, but it is not degradable

within the human or animal body due to the lack of certain enzymes. Material samples

will be prepared in the form of filaments for 3D printing. Three-dimensional printing

technology is a quick and easy way to create different models, and in this thesis will be

used to create a printing form for letterpress printing. In the first step, plates of certain

dimensions will be made on which various measurements will be performed to

determine their surface, structural and mechanical properties in order to characterize the

appropriate material that would match the properties of printing forms used in

letterpress printing.
