Space product assurance - Processing and quality assurance requirements for metallic powder bed fusion technologies for space applications

The scope includes metallic Powder Bed Fusion technologies for space applications.
A clear definition and implementation of quality monitoring and control means is mandatory and shall address the full end to end metallic PBF process, encompassing:
• Design / Simulation
• Materials management (Powder, shielding gases, other consumables, recycling, etc.)
• Processing
• Post Processing
• Testing
By developing a single standard which can be tailored in the Project definition phase, it will help the Space Industry in performing the following functions
related to metallic PBF technologies over the full end to end process:
(i) select and qualify metallic PBF processes for the appropriate application,
(ii) select and validate raw materials for the appropriate applications,
(iii) define monitoring and control means during production to ensure that metallic PBF parts are produced with the required quality,
(iv) define requirements for applying Non-Destructive Inspection methods for the different metallic PBF parts,
(v) define requirements to verify/qualify space parts produced by metallic PBF processes for the selected applications and associated environment,
(vi) define specific requirements for operators/inspectors/instructors certification,
(vii) define requirements for metallic PBF machines certification,
(viii) define requirements for metallic PBF Companies certification.
The Standard will be complemented with informative Annexes, listing guidelines and best practices on specific technical aspects.

Assurance produit des projets spatiaux - Exigences de traitement et d'assurance qualité pour les technologies de fusion sur lit de poudre métallique pour applications spatiales

La présente norme définit les exigences de traitement et d'assurance qualité pour les technologies de fusion sur lit de poudre destinées aux applications spatiales.
La présente norme spécifie un ensemble de phases propres aux technologies de fusion sur lit de poudre métallique qui doivent chacune être suivies lors de la définition, de la vérification et de la fabrication des pièces. De plus, elle décrit les exigences relatives au personnel d'exploitation et de supervision ainsi qu'aux installations et équipements.
La présente norme ne vise pas à prescrire des paramètres de procédé en rapport avec l'utilisation des technologies de fusion sur lit de poudre métallique.
Même si cette norme a été développée autour de techniques basées sur la fusion sur lit de poudre, ses principes peuvent également servir de référence pour d'autres procédés à base de métaux et de polymères. Il s'agit, entre autres, de la fabrication additive par arc électrique (WAAM, Wire Arc Additive Manufacturing), de la stéréolithographie (avec métaux), de la projection de liant, mais aussi du frittage sélectif par laser (SLS, Selective Laser Sintering), de la stéréolithographie (avec polymères) et de la modélisation par dépôt fondu (FDM, Fused Deposition Modelling).

Zagotavljanje kakovosti proizvodov v vesoljski tehniki - Zahteve za obdelavo in zagotavljanje kakovosti za fuzijske tehnologije kovinskega prahu za uporabo v vesoljski tehniki

Področje uporabe vključuje fuzijske tehnologije kovinskega prahu za uporabo v vesoljski tehniki.
Jasna opredelitev ter izvajanje spremljanja in nadzora kakovosti je obvezno. Dokument obravnava celoten postopek fuzijske tehnologije kovinskega prahu, ki vključuje:
• projekt/simulacijo
• upravljanje z materiali (prah, zaščitni plini, drug potrošni material, recikliranje itd.)
• obdelavo
• naknadno obdelavo
• preskušanje
Z razvojem enotnega standarda, ki ga je mogoče prilagoditi v fazi opredelitve projekta, bo standard pomagal vesoljski industriji pri izvajanju naslednjih funkcij,
povezanih s celotnim postopkom fuzijske tehnologije kovinskega prahu, kar vključuje:
(i) izbiro in preverjanje postopka fuzijske tehnologije kovinskega prahu za ustrezno uporabo,
(ii) izbiro in potrditev surovin za ustrezno uporabo,
(iii) opredelitev načinov spremljanja in nadzora med proizvodnjo, da se zagotovi, da so deli, izdelani s fuzijsko tehnologijo kovinskega prahu, zahtevane kakovosti,
(iv) opredelitev zahtev za uporabo metod neporušitvenega preskušanja za različne dele, izdelane s fuzijsko tehnologijo kovinskega prahu,
(v) opredelitev zahtev za potrjevanje/preverjanje vesoljskih delov, izdelanih s postopki fuzijske tehnologije kovinskega prahu, za izbrano uporabo in povezano okolje,
(vi) opredelitev posebnih zahtev za certificiranje upravljavcev/inšpektorjev/inštruktorjev,
(vii) opredelitev zahtev za certificiranje strojev za postopke fuzijske tehnologije kovinskega prahu,
(vii) opredelitev zahtev za certificiranje podjetij za postopke fuzijske tehnologije kovinskega prahu.
Standard bo dopolnjen z informativnimi dodatki, seznamom smernic in dobro prakso glede posebnih tehničnih vidikov.

Introduction
This Standard specifies the processing and quality assurance requirements for
the different types of Powder Bed Additive Manufacturing for Metallic Materials
for space flight applications. It can also be used for Additive Manufacturing
activities on space related ground equipment and development models for flight
hardware. The Standard covers all Powder Bed Additive Manufacturing
processes using Laser or Electron Beam as melting source. This includes, but is
not limited to:
 Selective Laser Melting (SLM)
 Direct Metal Laser Sintering (DMLS)
 Laser Sintering in Solid Phase (LSSP)
 Laser Beam Melting (LBM)
 Electron Beam Melting (EBM)
This standard may be tailored for the specific characteristic and constraints of a
space project in conformance with ECSS-S-ST-00.

Scope
This Standard defines requirements for processing and quality assurance of
powder bed fusion technologies for space applications.
Within this standard a set of phases are specified, each to be followed when
defining, verifying and manufacturing parts using metallic powder bed fusion
technologies. In addition, requirements for operating and supervision personnel
and equipment facilities are described.
This Standard does not aim to prescribe process parameters relevant to the
fabrication using metallic powder bed fusion technologies.
Although this standard is developed for powder bed fusion based techniques, its
principles can also be used for other metal-based and polymer-based processes.
These include Wire Arc Additive Manufacturing (WAAM), Laser Powder Build
up Welding (LPBW), Stereolithography (with metals), Binder Jetting, but also
Selective Laser Sintering, Stereolithography (with polymers), Fused Deposition
Modelling (FDM), and oth
...

Introduction
This Standard specifies the processing and quality assurance requirements for
the different types of Powder Bed Additive Manufacturing for Metallic Materials
for space flight applications. It can also be used for Additive Manufacturing
activities on space related ground equipment and development models for flight
hardware. The Standard covers all Powder Bed Additive Manufacturing
processes using Laser or Electron Beam as melting source. This includes, but is
not limited to:
 Selective Laser Melting (SLM)
 Direct Metal Laser Sintering (DMLS)
 Laser Sintering in Solid Phase (LSSP)
 Laser Beam Melting (LBM)
 Electron Beam Melting (EBM)
This standard may be tailored for the specific characteristic and constraints of a
space project in conformance with ECSS-S-ST-00.

Scope
This Standard defines requirements for processing and quality assurance of
powder bed fusion technologies for space applications.
Within this standard a set of phases are specified, each to be followed when
defining, verifying and manufacturing parts using metallic powder bed fusion
technologies. In addition, requirements for operating and supervision personnel
and equipment facilities are described.
This Standard does not aim to prescribe process parameters relevant to the
fabrication using metallic powder bed fusion technologies.
Although this standard is developed for powder bed fusion based techniques, its
principles can also be used for other metal-based and polymer-based processes.
These include Wire Arc Additive Manufacturing (WAAM), Laser Powder Build
up Welding (LPBW), Stereolithography (with metals), Binder Jetting, but also
Selective Laser Sintering, Stereolithography (with polymers), Fused Deposition
Modelling (FDM), and others.
