Abstract
Diplomsko delo obravnava možnosti tiskanja nosilnih gradbenih konstrukcij z uporabo 3Dtiska. V ta namen so na začetku predstavljene prednosti tehnologije in njeni pozitivni vplivi tako na področju varovanja okolja, kot tudi na finančnem področju. Sledi klasifikacija različnih tehnologij in njihova kratka predstavitev. Poudarek je bil narejen tudi na vpliv orientacije vlaken s tehnologijo modeliranja s spajanjem slojev (FDM) natisnjenih vzorcev na njihovo natezno in upogibno nosilnost ter odpornost na utrujanje. V nadaljevanju so predstavljeni dosežki 3D-tiska na področju gradbeništva, podrobneje pa je predstavljeno področje tiskanja kovinskih konstrukcij oziroma konstrukcijskih sklopov. Na primeru mostu v Amsterdamu, ki bo v celoti izdelan s tehnologijo 3D-tiska, je predstavljena možnost gradnje polno nosilnih gradbenih konstrukcij in njenih prednosti pred trenutno uporabljanimi tehnikami gradnje. S topološko optimizacijo vozlišča palične konstrukcije smo pokazali, da uporaba 3D-tiska tudi v gradbeništvu omogoča nov pristop k projektiranju konstrukcij. Zaradi sposobnosti tiska poljubnih oblik, brez dodatnih stroškov, lahko gradimo lažje konstrukcije, material pa uporabimo samo na mestih, kjer je to nujno potrebno. V delu je poleg topološke optimizacije predstavljena tudi optimizacija strukture materiala, ki z uporabo 3D-tiska dobiva nov pomen. Na ta način je možno razviti nove materiale, ki bodo bolj nosilni, hkrati pa tudi lažji od sedaj poznanih. Tiskanje gradbenih konstrukcij ni iluzija in samo vprašanje časa je, kdaj in do kakšne mere bo 3D-tisk nadomestil utečene tehnike gradnje objektov.

Title:Printing of construction components; illusion or reality?
Abstract:
The thesis deals with possibilities of printing of load bearing constructions with the use of a 3D printer. Therefore in the introduction, advantages and positive impacts of this technology both in the field of environmental protection, as well as in the financial sector are presented, followed by classification and short presentation of different technologies. The focus is also made on the significance of how fibers orientation in the FDM printed specimens effects on tensile, flexural and fatigue strengths. Furthermore, achievements of 3D printing in construction are presented, and, in detail, the field of metal construction printing and construction components, respectively. Additionally, a bridge in Amsterdam is presented as an example of 3D printer capability to build load bearing constructions. It also shows us advantages that 3D printing has over traditionally used construction techniques. With topological optimization of truss nodes, it is shown that use of 3D printing technology in construction enables a new approach to construction designing; we can build lighter constructions and use the construction material only in places where it is crucial. This is due to the unique ability to print any form, without additional expenses. Besides topological optimization, the thesis also includes material optimization, which gets a whole new meaning using 3D printing technology. It is possible to develop new materials which are stronger, yet lighter this way. 3D Printing of building construction is not an illusion, it is only a question of when and to what extent will this technology replace the well-established techniques of building construction.

Keywords:graduation thesis, 3D-printing, topological optimization, material optimization, free form, construction components
