Abstract:S skokovitim razvojem in razmahom naprav za proizvodnjo, tako klasičnih odrezovalnih kot postopkov slojevitih tehnologij (znanih tudi kot 3D tiskalniki), se pojavi vprašanje, kako med množico tehnologij in naprav izbrati ustrezno. Delo opisuje osnovne značilnosti STL formata, kot izhodne CAD datoteke, ki predstavlja osnovo za analizo in razvoj postopkov določevanja kompleksnosti oblike samega modela. Predstavljenih je več modelov iz realnega okolja, na katerih je izvedena analiza vhodnih podatkov in postopek določevanja kompleksnosti oblike. Predstavljeni so aktualni izdelovalni postopki, primerni tako za izdelavo unikatnih izdelkov kot tudi za serijsko izdelavo, s posebnim poudarkom na slojevitih tehnologijah. Na osnovi temeljnih lastnosti izdelovalnih tehnologij so analizirani testni modeli in s pomočjo ocene kompleksnosti določeni primerni postopki izdelave oziroma čas, potreben za poobdelavo posameznega izdelka, izdelanega po postopkih slojevitih tehnologij. Rezultati so primerljivi z izkustveno določitvijo izdelovalnega postopka na osnovi ocene strokovnjakov, sistem določevanja izdelovalnega postopka je mogoče z manjšimi prilagoditvami praktično uporabiti.

Title:DEVELOPMENT OF A PART-COMPLEXITY EVALUATION MODEL FOR APPLICATION IN ADDITIVE FABRICATION TECHNOLOGIES
Abstract:With the rapid development and expansion of devices for the production of both traditional (cutting) procedures and layered technologies (also known as 3D printers or rapid prototyping/manufacturing), the question arises as to how to find the appropriate production technology. This work describes the basic features of the CAD output file STL. The STL file format is a widely-used file format developed for layered technologies and, as such, a basis for analysing and developing methods when determining the complexity of a model. Several real-life models are presented for the analyses of basic data, and complexity determination. Actual manufacturing procedures suitable for the manufacture of unique products or serial production are presented, with accentuation towards layered technologies. Technological test models are analyzed based on the fundamental properties of manufacturing and certain manufacturing processes are chosen using complexity estimation. Complexity evaluation is also used for post processing time determination. The results are comparable with those choices of manufacturing procedures on the basis of experts' estimates; the system of determining manufacturing procedures on the basis of model-complexity has practical usage.
