Razvoj profila materiala Ultrafuse 316LX za 3D tiskalnik BigRep STUDIO 62 : diplomsko delo

Brdnik, Tin (author), Mrvar, Primož (mentor)

V podjetju BigRep je bil ustvarjen profil za tiskanje materiala s kovinskim prahom Ultrafuse 316LX za 3D tiskalnik BigRep STUDIO G2. Profil z izbranimi parametri za tiskanje, v programskem orodju BLADE, omogoča 3D tiskanje kompozitnega materiala polimera z dodatkom nerjavečega jekla (okoli 80 mas. %). Model je najprej ustvarjen v programski opremi za 3D modeliranje. Sledi pretvorba digitalne datoteke v .stl format. Model se v programskem orodju za razrez razdeli na sloje določene višine ki so natisnjeni na 3D tiskalniku. Po končanem tiskanju sledita postopka odstranjevanja veziva in sintranje. Rezultat je popolnoma kovinski produkt. Diplomsko delo predstavlja pogled v razvoj in uporabo aditivne tehnologije. V eksperimentalnem delu so bili izvedeni različni testi optimizacije profila. Med drugimi lastnostmi so bile določene vrednosti optimalne temperature tiskanja, največje hitrosti, največjega možnega kota tiskanja, možnost tiskanja z različnimi vrstami podpore, izboljšana je bila adhezija na tiskalno podlago. Po končanem tisku so bile izmerjene dimenzijske vrednosti modelov v treh smereh. Poslani so bili podjetju BASF, kjer sta bila izvedena procesa odstranitve veziva in sintranje. Iz ponovnih meritev je bil izračunan skrček med procesom sintranja. S pomočjo te vrednosti je mogoče načrtovati dimenzijsko ustrezne modele v prihodnosti. Izveden je bil tisk modela diska s hladilnim kanalom, ki predstavlja geometrijo, ki jo je težko izdelati s tradicionalnimi metodami. Z namenom prikaza možnosti uporabe materiala je bila prav tako natisnjena serija modelov različnih geometrij.

Abstract

The development of the printing profile of Ultrafuse 316LX material for 3D printer BigRep STUDIO G2 was made while working in the BigRep 3D printing Company. The profile parameters in slicing software BLADE enable 3D printing of the composite material made from polymers with addition of stainless steel particles (around 80 wt. %). At the beginning the model is designed in 3D CAD software. Then the digital file is converted to .stl format. Slicer software is used to cut the model in slices with certain height and printed on 3D printer. After the printing, the part goes through processes of debinding and sintering. The result is completely metal product. The thesis presents a view on the development and usage of additive technology. In the experimental work test were made to insure optimisation of the profile. Optimal values for the following parameters were assigned: temperature of printing, maximal speed, maximal angle of printing, possibility of printing with support, bed adhesion was improved. After the printing was complete measurements of the part were made in X, Y and Z direction. Parts were sent to the company BASF where they were implemented to the processes of debinding and sintering. With the measurements after sintering process shrinkage was calculated. This value enables the design of dimensional accurate parts in the future. A disk with cooling channel was produced with this method. It represents geometry that is hard to produce with traditional methods of production. A series of different models were also printed to show the areas of possible application for the material.
