Abstract

The advantages of individuality and complexity for free are commonly known in the field of additive manufacturing, but, nevertheless, they compete with advantages of conventional manufacturing methods. On the one hand, a small size production can be economically viable through additive manufacturing. On the other hand, conventional manufacturing methods are well known and optimized, so that they have low cost per unit. Therefore, to evaluate the economic efficiency various criteria are needed to compare additive and conventional manufacturing methods. In the following part comparative criteria and influence factors for economic efficiency are identified and described. Besides general aspects personal reasons may influence a manufacturing decision. Therefore, the identified criteria are used to build a method which helps the user to decide on a manufacturing method depending on personal preferences. The structure and use of this method is described in the second part. After this, an outlook and conclusion is given.

Die Vorteile der kostenlosen Individualität und Komplexität sind im Feld der Additiven Fertigung allgemein bekannt, trotzdem konkurrieren additive Fertigungsverfahren mit konventionellen Fertigungmethoden. Einerseits kann vor allem die Produktion kleiner Losgrößen ökonomisch lohnend sein bei Nutzung eines Additiven Fertigungsverfahren. Andererseits sind konventionelle Fertigungsmethoden sehr gut erforscht und optimiert, sodass niedrige Stückkosten erzielt werden können. Um die Wirtschaftlichkeit der additiven und konventionellen Fertigung zu vergleichen, müssen Vergleichskriterien genutzt werden, die im Folgenden identifiziert und beschrieben werden. Zusätzlich beeinflussen individuelle Präferenzen die Entscheidung für eine Fertigungsmethode, weshalb diese neben den Entscheidungskriterien Beachtung finden. Die Erkenntnisse werden in einer Methode zusammengeführt, die einem Nutzer die Entscheidung für eine Fertigungsmethode erleichtern soll.German
