Izdelava funkcionalnega prototipa plezalne opreme s 3D tiskom

Caserman, Mark (avtor), Muck, Deja (mentor)

Namen diplomskega dela je bil raziskati potencial tehnologije 3D tiska za izdelavo prototipov kompleksne plezalne opreme, specifično plezalne vponke. Osredotočenost je bila na procesu od digitalnega modeliranja do fizične izdelave plastičnega in kovinskega prototipa. V programskem okolju Fusion 360 je bil najprej zasnovan 3D model vponke, pri čemer so bila upoštevana nekatera načela oblikovanja za dodajalno izdelavo. Nato je bil izbrani model fizično realiziran z uporabo tehnologij modeliranja s spajanjem slojev FDM (angl. Fused Deposition Modelling) in selektivnega laserskega taljenja SLM (angl. Selective Laser Melting). Po končanem tiskanju so bili izvedeni osnovni koraki naknadne obdelave, kot sta odstranjevanje podpornih struktur in površinska obdelava. Izdelani prototipi so bili ovrednoteni z vizualno oceno kakovosti izdelave in kakovosti tiska površine ter z izvedbo dimenzijskih meritev za primerjavo z originalnim CAD modelom. Z rezultati je bilo potrjeno, da je s tehnologijami 3D tiska, kot sta FDM in SLM, mogoče uspešno izdelati geometrijsko natančen prototip plezalne vponke, ki je uporabna kot fizični model za oceno oblike in prileganja. Čeprav v SLM tehnologiji obstajajo obetavne možnosti za izdelavo kompleksnih kovinskih komponent plezalne opreme, sta za potrditev dejanske funkcionalnosti in varnosti za uporabo v praksi nujni nadaljnja optimizacija procesa in predvsem rigorozno mehansko testiranje v skladu z veljavnimi standardi.

Izvleček

This diploma thesis aimed to explore the potential of 3D printing technology for prototyping complex climbing equipment, specifically a climbing carabiner. The focus was on the process from digital modelling to the physical fabrication of both a plastic and a metal prototype. A 3D model of the carabiner was designed in Fusion 360, incorporating principles of Design for Additive Manufacturing. The model was then physically realised using Fused Deposition Modelling (FDM) and Selective Laser Melting (SLM) technologies. After printing, basic post-processing steps, such as support structure removal and surface finishing, were performed. The manufactured prototypes were evaluated through visual inspection of the build quality and surface finish, as well as by dimensional measurements for comparison with the original CAD model. The results confirm that 3D printing technologies, such as FDM and SLM, can be used to produce a geometrically accurate prototype of a climbing carabiner, serving as a physical model for form and fit assessment. Although SLM technology offers promising possibilities for manufacturing complex metal components for climbing equipment, further process optimization and, crucially, rigorous mechanical testing in accordance with applicable standards (e.g., UIAA, EN) are essential to confirm actual functionality and safety for practical use.
