Uobičajna svrha ove intervencije je zaštita moždanog tkiva, smanjenje lokalnog bola i poboljšanje estetike kranijalnog svoda. Kranijalne proteze mogu biti napravljenje od različitih materijala: autologne kosti, titanijuma, keramike i polimera. Njihova proizvodnja je skupa i često zahtijeva kompleksne intraoperativne procese, što ponekad rezultira slabim estetskim rezultatima kod velikih i kompleksnih defekata. Ovaj rad, na konkretnom primjeru, predstavlja metod za izradu implanta po mjeri pacijenta od polimetil metakrilata, uključujući trodimenzionalnu rekonstrukciju baziranu na CT snimcima, tehnologiju 3D printanja i izradu kalupa od zubarskog gipsa.

3D printing technology is leading to great advancements and expanding the limits in many engineering fields and education. Geometrical accuracy of the parts produced by 3D printing could be a very important characteristic for some purposes. In this paper the geometrical accuracy of parts produced by FDM (Fused Deposition Modelling) 3D printing technology is investigated. For this purpose a benchmark part is designed and size, form, orientation and location accuracy of different features on it are evaluated using coordinate measuring machine. Two different FDM desktop 3D printers are used for the benchmark part printing.

This paper gives an overview of possible applications of contemporary e-learning platforms in the organisation of teaching in higher education and their advantages and disadvantages compared to the traditional approach. Two platforms, namely, Moodle and Blackboard, are considered with the focus on the possibility of their application for knowledge assessments. Two examples of the online organisation of the knowledge assessment using E-learning platforms are given.
