Povzetek

Oblikovali in natisnili smo vezne elemente, s katerimi bi skupaj z enostavnimi lesenimi elementi lahko sestavili estetsko zanimivo mizo, ki bi ustrezala zahtevam standardov. Miza je bila oblikovana tako, da je enostavna za sestavo in pri tem ni potrebna uporaba posebnih orodij. Konstruirana je bila s programom SolidWorks, v katerem smo s simulacijami obremenitev tudi preizkušali variante veznikov. Izbrano varianto veznikov smo nato 3D natisnili iz PLA-polimera, za ostale dele mize pa smo uporabili topolovo vezano ploščo in borove palice. Lesene in 3D natisnjene dele smo sestavili s poliuretanskim lepilom in vijaki. Mizo smo nato testirali po metodah standarda SIST EN 1730:2012 in zahtevah standarda SIST EN 12521:2010. Miza ni prestala prvega testa vertikalne obremenitve, saj so popustili trije vezni elementi. Na podlagi teh testov in simulacij smo nato konstruirali še tretjo verzijo mize. Simulacije v programu so pokazale, da bi ta miza lahko prestala večje obremenitve in pri tem imela manjše deformacije. Ugotovili smo, da je mogoče izdelati mizo s 3D natisnjenimi vezniki, vendar je za zadostitev zahtevam standarda SIST EN 1730:2012 potrebna še optimizacija celotnega procesa

Sekundarni naslov:	Development of a table with 3D printed connectors
Sekundarni povzetek:	We designed and 3D printed connectors that, along with simple wooden elements, allowed us to assemble an aesthetically interesting table that meets the requirements of the related standards. The table was designed to be easily assembled without the need for special tools. It was designed using the SolidWorks program, in which we also tested various connection variants with load simulations. The selected variant of the connectors was then 3D-printed from PLA polymer, and for the other parts of the table we used poplar plywood and pine elements. The wooden parts and 3Dprinted parts were assembled using one-component polyurethane glue and screws. The table was then tested according to the methods of the SIST EN 1730: 2012 standard and the requirements of the SIST EN 12521: 2010 standard. The table failed the initial vertical load test because three connecting elements failed. Based on testing and simulations, we then designed another, third version of the table. The simulations in the program showed that this table could withstand higher loads and had lower deformations. We concluded that it was possible to produce a table with 3D connectors, but optimization of the whole process is still needed to meet the requirements of the standard SIST EN 1730: 2012.
