Abstract
Knowledge about the capabilities of a production system is an important issue. The three-dimensional (3-D) printing (drop-on-bed) process has become a well-established Additive Manufacturing (AM) technology. Initially intended for use mainly as a concept modeller, its scope of application has expanded to include, among others, fit and functional models, pattern-making for casting and moulding processes, rapid tooling, and medical and architectural models. This growth in applications has stimulated a reciprocal improvement in available materials and the technological capabilities of 3-D printing, such as accuracy, strength and elongation, surface finish, build time, and cost. These factors are of significance to users who want to control their processes better and to designers who want to define their expectations and determine their requirements. Thus this paper aims to provide a technical update, highlighting the influence level of different factors on a system’s capabilities. This paper uses the example of the ZPrinter 310 system from the Z Corporation, applies appropriate statistical techniques, and takes into consideration the latest material and machine developments, in order to report on the current improvements of the capability profile of this important process.
Kennis oor die vermoëns van ’n produksie sisteem is ’n baie belangrike kwessie. Die 3-D druk proses het ’n goed gevestigde additiewe vervaardigingstegnologie geraak. Aanvanklik was die hoof doel hiervan om konsepte te modelleer, maar nou is die toepassing uitgebrei om, onder andere, pas en funksionele modelle, patroon vervaardiging van giet prosesse, snel vervaardiging van gereedskap, mediese modelle, en argitektoniese modelle in te sluit. Hierdie groei in aantal toepassings het ’n wedersydse verbetering in die beskikbaarheid so wel as tegnologiese vermoëns van 3-D druk soos akkuraatheid, sterkte, verlenging, afwerking, bou tyd, en kostes tot gevolg gehad. Hierdie faktore is baie belangrik vir gebruikers om beter beheer toe te pas oor hul prosesse, en vir ontwerpers om hul verwagtinge te definieer en om vereistes te bepaal. Hierdie artikel het ten doel om ’n tegniese opdatering te gee van wat die invloed van verskillende faktore op ’n sisteem se vermoëns is. Deur gebruik te maak van die ZPrinter 310 sisteem van Z-Corporation as voorbeeld, en met die toepassing van gepaste statistiese tegnieke en inagneming van onlangse materiaal- en masjienontwikkelinge, word die nuutste verbeteringe van die vermoënsprofiel vir 3-D druk tegnologie bespreek.
