Izdelava litofana z uporabo 3D-tiska

Klokočovnik, Jure (author), Muck, Deja (mentor)

V diplomskem delu je opisan postopek izdelave litofana s pomočjo 3D tiska. V teoretičnem delu je najprej predstavljena tehnologija 3D-tiska in podrobneje opisana tehnologija ekstrudiranja materialov oziroma termoplastov, modeliranje s spajanjem slojev. Sledi pregled materialov, ki se uporabljajo za 3D-tisk z omenjeno tehnologijo. V nadaljevanju so opisani postopki 3D zajema in reproduciranja reliefnih predmetov, na koncu teoretičnega dela pa je predstavljen še sam litofan. V eksperimentalnem delu je predstavljen celoten postopek izdelave litofana. Za izdelavo modela litofana je bil uporabljen program za 3D modeliranje, Blender, litofani v fizični obliki pa so bili izdelani s 3D tiskalnikom Creality Ender 3 in z uporabo filamenta PLA. Pri izdelavi barvnih litofanov sta bila dodatno uporabljena še kapljični in elektrofotografski tiskalnik. Primerjal se je tudi vpliv LED svetila in halogenske žarnice na končni vtis reprodukcije litofana. V poglavju rezultati, se je primerjalo litofane izdelane z različnimi nastavitvami tiska in različne barvne reprodukcije le-teh. Rezultati so pokazali, da je najboljša debelina stene en milimeter in debelina slojev najmanjša vrednost, ki jo omogoča tiskalnik. Orientacija litofana med tiskom, močno vpliva na končno podoba motiva. Najboljša orientacija je pokončna. Barvna reprodukcija je najboljša z uporabo elektrofotografskega tiska v kombinaciji z akrilnim lakom. Ugotovitev glede osvetlitev je pokazala, da so LED svetila bolj primerna od halogenskih žarnic. Končni litofan je bil zadovoljive kakovosti in bi ga lahko uporabili kot dekoracijo doma ali priredili umetnostno razstavo večjega števila barvnih litofanov in pri tem reproducirali različne umetnine in motive.

• Title: Making a 3D Printed Lithophane

Abstract

In this diploma thesis, a lithophane has been created with the help of 3D printing. The theoretical part presents a look at 3D printing technology and a more in-depth look at material extrusion technology also known under the term fused deposition modelling. An overview of used materials and methods followed. Methods of 3D capture, relief reproduction and lithophanes are further described at the end of the theoretical part. The whole process of making a lithophane is described in the experimental part. The model of the lithophane was created with 3D modelling software Blender, however the lithophane itself was printed with 3D printer Creality Ender 3 and PLA filament. For the colour reproduction part of the thesis, inkjet and electrophotographic printers were used. In addition, LED and halogen bulb light and their effect on colour were observed. In the results chapter, lithophanes with different printing settings and colour reproduction of them were compared. Moreover, the results show, that the best parameters are a one-millimetre-thick wall and the best layer height our printer could do. The orientation of the lithophane during the print is crucial. The results show that the best orientation is upright. The best colour reproduction has been achieved with an electrophotographic print and acrylic varnish. Backlight research showed that LED is much better suited for the job than a halogen lightbulb. The finished product was satisfactory and could be used as a home decoration or even as an art display, where we would present many coloured lithophanes with different motives on them.
