According to the great impact of additive technology on the development of modern industry, a lot of research is being done to obtain 3D printed parts with better properties. This research is extremely important because there are no scientific papers in the field of post dyeing of acrylonitrile/butadiene/styrene (ABS) 3D printed parts. The experiment was carried out using disperse dyes on ABS specimens. The obtained coloration of the specimens was in the primary colors (yellow, red, and blue) in the specified dyestuff concentration range and was evaluated using an objective CIELab system. Based on the obtained color parameters, remission values and Kubelka-Munk coefficient, dye mixtures and an ombre effect were performed to obtain patterns in the desired hues. Abrasion resistance of disperse dyed specimens was tested using different abrasive materials over a wide range of fineness to simulate different indoor and outdoor soils and was compared to abrasion resistance of specimens produced from the industrially dyed wire with the master batch. The results show that 3D printed ABS products can be produced in one or more desired shades with satisfactory abrasion resistance. This undoubtedly represents the added value of 3D printed ABS parts and extends their application to the field of creative industries and design, specifically footwear design.

Functionality and appearance are key aspects of good footwear. Developments in recent science and technology offer a wider scope of innovations, contributing to diversity and higher complexity of the production concept of footwear. Contemporary industrial footwear market offers a practically limitless number of new design and fashion solutions, often of quite similar appearance, but with significant differences in quality level, both regarding manufacture, raw material content, durability, and in some special functional finishes. The materials for footwear manufacture are functionalized for functional protective purposes, such as antimicrobial, waterproofing, fire resistant, wear and tear resistant, and recently for some therapeutical purposes. Novelties in material functionalization for the materials built in the footwear are most often promoted and presented on tags and labels and are used as advertisement issues, while some functionalities have become a logo for some brands.

U industriji obuće, sve je veća pozornost na dizajnerski oblikovane potpetice. Ali taj dizajn uključuje mogućnost proizvodnje složene geometrije, personaliziranih potpetica male mase i ako je moguće jeftinu izradu. Tehnologija koja omogućuje i obuhvaća navedeno je aditivna proizvodnja (e. additive manufacturing - AM). Jedna od AM niskobudžetnih tehnologija i uređaja je postupak taloženog očvršćivanja (e. fused deposition modeling - FDM). U FDMu se proizvod izrađuje sloj po sloj, s različitim oblicima i gustoćom unutrašnjih ispuna što omogućuje izradu složenih geometrija i malu masu. Tijekom hodanja potpetica je opterećena odozgo pritisnom silom same težine osobe, dok je bočno izložena savijanju i udarnom opterećenju. Uzimajući u obzir dizajn same potpetice, potrebno je pravilno orijentirati proizvod u radnom prostoru stroja, jer orijentacija utječe na mehanička svojstva. U ovom su radu provedena ispitivanja savojnih svojstava kod dvije različite orijentacije s obzirom na proizvodnju stvarne potpetice i njene primjene. Nadalje, načinjena je analiza parametara prerade (debljina sloja, gustoća ispune i temperatura ispisa) kako bi se utvrdio njihov utjecaj na savojna svojstva u te dvije orijentacije.
