Additive manufacturing - Design - Part 1: Laser-based powder bed fusion of metals (ISO/ASTM 52911-1:2019)
This document specifies the features of laser-based powder bed fusion of metals (PBF-LB/M) and provides detailed design recommendations.
Some of the fundamental principles are also applicable to other additive manufacturing (AM) processes, provided that due consideration is given to process-specific features.
This document also provides a state of the art review of design guidelines associated with the use of powder bed fusion (PBF) by bringing together relevant knowledge about this process and by extending the scope of ISO/ASTM 52910.
Additive Fertigung - Konstruktion - Teil 1: Laserbasierte Pulverbettfusion von Metallen (ISO/ASTM 52911-1:2019)
Dieses Dokument legt die Merkmale der laserbasierten Pulverbettfusion von Metallen (PBF LB/M) fest und bietet detaillierte Konstruktionsempfehlungen.
Einige der grundlegenden Prinzipien gelten auch für andere additive Fertigungsverfahren (AM Verfahren), vorausgesetzt, dass die prozessspezifischen Merkmale berücksichtigt werden.
Dieses Dokument bietet eine Übersicht von Konstruktionsleitfäden auf dem Stand der Technik im Zusammen¬hang mit pulverbettbasiertem Schmelzen (PBF), indem relevantes Wissen zu diesem Verfahren zusammengeführt und der Anwendungsbereich von ISO/ASTM 52910 erweitert wird.
Fabrication additive - Conception - Partie 1: Fusion laser sur lit de poudre métallique (ISO/ASTM 52911-1:2019)
Le présent document spécifie les caractéristiques de la fusion laser sur lit de poudre métallique (PBF-LB/M) et fournit des recommandations de conception détaillées.
Certains des principes fondamentaux sont également applicables à d'autres procédés de fabrication additive (FA), sous réserve que les caractéristiques spécifiques à un procédé soient dûment prises en compte.
Le présent document fournit également un État de l'Art des lignes directrices de conception associées à l'utilisation d'une fusion sur lit de poudre (PBF), en compilant des connaissances pertinentes sur ce procédé et en élargissant le domaine d'application de l'ISO/ASTM 52910.
Aditivna proizvodnja - Konstruiranje - 1. del: Selektivno lasersko pretaljevanje kovinskega prahu (ISO/ASTM 52911-1:2019)
Namen tega standarda je zagotoviti inženirjem za načrtovanje in proizvodnjo delovno podlago, ki jim omogoča sprejemanje utemeljenih odločitev glede uporabe laserske fuzije kovinskih prahastih plasti. Ta standard opisuje značilnosti laserske fuzije kovinskih prahastih plasti in podaja podrobna priporočila za načrtovanje. Nekatera temeljna načela je mogoče uporabiti tudi pri drugih procesih aditivne proizvodnje, pod pogojem, da se upošteva značilnosti procesa. Namen tega standarda je izvajalcem pomagati raziskati prednosti laserske fuzije kovinskih prahastih plasti ter prepoznati omejitve, povezane s procesi, pri načrtovanju delov.
Dokument ponuja tudi najsodobnejši pregled smernic za načrtovanje, povezanih z uporabo fuzije prahastih plasti, ki združujejo ustrezno znanje o tem procesu in razširjajo področje uporabe standarda ISO/ASTM 52910, »Standardnega vodila za načrtovanje aditivne proizvodnje«.
