Abstract

Razvojem računalne tehnologije postavili su se novi zahtjevi u obliku ubrzanja proizvodnje te
povećanje kvalitete i raznovrsnosti proizvoda na tržištu. Kao odgovor na nove trendove pojavio
se koncept brzog razvoja proizvoda (eng. Rapid Product Development) , čije su mnogobrojne
inačice prije desetak godina obuhvaćene izrazom - aditivna proizvodnja (eng. Additive
Manufacturing). Aditivna proizvodnja podrazumijeva, na temelju računalnog modela,
dodavanje materijala sloj po sloj tvoreći na taj način trodimenzionalni proizvod. U modernoj
industriji, aditivna tehnologija svoju primjenu pronalazi prije svega kod maloserijske
proizvodnje složenih geometrija, gdje je zahtijevana preciznost izrade. Jedna od aditivnih
tehnika jest nanošenje rastaljenog polimernog materijala (eng. Fused Filament Fabrication -
FFF), razvijena 2005. godine. Naime, uporabom 3D pisača, polimerni materijal u obliku
filamenta se tali te se kao i kod ostalih aditivnih procesa, nanosi u slojevima prateći konture
računalno modelirane konstrukcije. U začetcima, 3D pisači koristili su se za izradu prototipova,
međutim danas se njima izrađuju konačni proizvodi. Ekspanzijom proizvođača, a samim time
i modela, potencijalnim investitorima se značajno otežao izbor 3D pisača jer vrsta i model
samih uređaja izravno utječu na svojstva proizvoda.

Abstract (english)

The development of computer technology has imposed new requirements for products offered
in the market in terms of variety, quality, and production acceleration. The concept of Rapid
Product Development and its numerous versions, which have been grouped under the term
Additive Manufacturing, emerged in response to these recent trends. Additive Manufacturing
encompasses the creation of a three-dimensional object by layering materials, with a
computational model of the product as the basis. This type of construction is nowadays most
commonly applied in small-scale manufacturing of complex geometries, a field that requires
high precision to detail. An example of a technique used in Additive Manufacturing is Fused
Filament Fabrication (FFF), developed in 2005: filament-shaped polymer material is melted
using a 3D printer and applied in layers in accordance with the contours of the computermodeled construction, which is a procedure followed in all Additive Manufacturing processes.
While 3D printers were used for prototyping when they were first developed, today they are
used to create final products. With the expansion of manufacturers, and subsequently printer
models, potential investors might have a hard time choosing the perfect 3D printer, as the device
type and model directly affect product quality.
