V diplomski nalogi je predstavljena izdelava prototipa glave filtra za komprimiran zrak z uporabo 3D tiskanja in vključuje idejno zasnovo, modeliranje, pripravo na tisk in tiskanje končnega izdelka po dveh različnih tehnologijah 3D tiska. Za uporabo 3D natisnjenega izdelka pri aplikaciji stisnjenega zraka, mora biti ta neprepusten in prenesti zahtevan nadtlak. V tem delu je prikazana vizualna in funkcionalna primerjava ter izvedba merjenja porušitvenega tlaka obeh natisnjenih prototipov. Dodatno je z računalniško simulacijo izvedena določitev tlačnega padca pri delovnih pogojih prototipa filtra, ki ima drugačno zasnovo zaradi zagotavljanja nižjega tlačnega padca. Rezultati kažejo, da je tisk s tehnologijo brizganja fotopolimera lahko uporaben za izdelavo tlačno obremenjenih izdelkov, saj je izdelek prenesel 11 bar nadtlaka, medtem ko izdelek, natisnjen s tehnologijo ciljnega nanašanja polimera, ni zagotavljal neprepustnosti in zato ni primeren za uporabo pri tlačnih aplikacijah. Računalniška določitev tlačnega padca pa nam je pokazala, da drugačna zasnova filtrske glave ne zagotavlja izrazitega zmanjšanja tlačnega padca v primerjavi z obstoječimi filtrskimi glavami konvencionalne zasnove.

• Title: Use of 3D printing to produce a compressed air filter head prototype

Abstract

This diploma thesis presents the production of compressed air filter head prototype using 3D print technology and includes conceptual design, modeling, print preparation and product printing with two different 3D print technologies. If 3D printed product is intended for compressed air application, it must guarantee fluid impermeability and withstand required pressure. Therefore, this thesis presents visual and functional comparison and also implementation of bursting pressure measurement of both printed products. Additionally, pressure drop of filter prototype under working conditions is determined using computer flow simulation, where structural design of filter head prototype is different than conventional to reach lower pressure drop. The results indicate, that the material jetting print technology is suitable for production of products, which are intended for compressed air applications, as the printed product did withstand a maximum pressure of 11 bar, whereas fused deposition modeling technology is not suitable, as the impermeability of the printed product was not achieved. Computer pressure drop measurements revealed, that different structural design of this filter head prototype does not guarantee noticeable lower pressure drop compared to the conventional design of filter head.
