1 19 JAN 2024 This revision streamlines the qualification process for Powder Bed Fusion (PBF) Additive Manufacturing procedures and components and added allowances for additional PBF technologies. The requirement for approval of the PBF Procedure prior to execution of procedure qualification builds has been removed. The requirement to perform nondestructive testing for procedure qualification has been rescinded, and nondestructive testing requirements have been revised for other areas.

Destructive testing requirements have been streamlined for procedure qualification and part verification. Electron beam PBF requirements have been added. Other clarifications to requirements have been made throughout the document.

FOREWORD-1/(FOREWORD-2 Blank)

FOREWORD

This document covers general requirements, provisions for quality assurance and process control plans, test procedures, and instructions for preparation for delivery for powder bed fusion-produced parts.

TECHNICAL MANUAL FEEDBACKS

Ships, training activities, supply points, depots, Naval Shipyards and Supervisors of Shipbuilding are requested to arrange for the maximum practical use and evaluation of NAVSEA technical manuals. All errors, omissions, discrepancies and suggestions for improvement to NAVSEA technical manuals shall be submitted via one of the following methods:

1. The preferred method is to submit the Feedback directly into MBPS at https://mbps.navseaplm.navy.mil/Windchill/. MBPS is an unclassified system, do not include U-NNPI or Classified data as attachments to a feedback. See option 5 for classified data. To request a MBPS account submit a ticket to the National Help Desk Service Management (NHDSM) at https://nhdsm.navair.navy.mil/ (DoD PKI Certificate required).

2. Submit a ticket via NHDSM. When submitting the ticket, include a completed copy of NAVSEA 4160/1 (TMDER Form). All data submitted via NHDSM shall be unclassified only.

3. Email a completed copy of NAVSEA 4160/1 to nav_helpdesk.fct@navy.mil. All data submitted shall be unclassified only.

4. For non-Help Desk account holders, submit the feedback via the following link (CAC or ECA Cert Required):

https://nhdsm.navair.navy.mil/HEAT/alp.aspx?Scope=SelfService&CommandId=NewServiceRequ estByOfferingId&Tab=ServiceCatalog&Template=1DE99338DBF9480D9CD3F6EE57B08124 When submitting the ticket, include a completed copy of NAVSEA 4160/1. All data submitted shall be unclassified only.

5. For NNPI and Classified data, continue to use the paper copy of NAVSEA 4160/1 and submit using the current process.

All feedback comments shall be thoroughly investigated, and originators will be advised of action resulting therefrom. One copy of NAVSEA form 4160/1 is at the end of each separately bound technical manual 8-1/2 x 11 inches or larger.

CHAPTER 1

SCOPE AND APPLICABILITY

1-1 SCOPE.

This document provides the minimum qualification requirements, part verification requirements, and performance requirements for fabricating metal parts using powder bed fusion (PBF) additive manufacturing (AM). This document also covers general requirements, provisions for quality assurance and process control plans, test procedures, and instructions for preparation for delivery of PBF-produced parts. Procedure qualification, part verification, and operator qualification requirements, as well as completion of all assessments and requirements for NAVSEA’s use of AM shall be met prior to any production fabrication. The requirements in this document are devised to demonstrate that sound PBF parts can be produced. This document does not purport to address all the safety concerns, if any, associated with the use of PBF. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1-2 NON-APPLICABILITY.

1-2.1 NAVAL NUCLEAR PROPULSION. This document does not apply to naval nuclear propulsion plant systems, equipment, and facilities under the cognizance of the Deputy Commander, Naval Nuclear Propulsion Directorate (SEA 08). As outlined in EO 12344, the SEA 08 Deputy Commander has responsibilities and authorities over all facilities and activities which comprise the Naval Nuclear Propulsion Program, which is a joint Department of Energy and Navy organization. These responsibilities and authorities include all technical and logistical matters related to naval nuclear propulsion. Accordingly, nothing in this document supersedes or changes those authorities, and SEA 08 shall be consulted concerning all matters related to naval nuclear propulsion.

1-2.2 STRATEGIC SYSTEMS PROGRAMS. This document does not apply to Strategic Weapons Systems, Attack Weapons Systems, and associated spare and repair parts under the cognizance of Strategic Systems Programs.

1-2.3 NON-CRITICAL APPLICATIONS. This document does not apply to applications covered by NAVSEA ltr Ser 05Z/191 or applications with service condition level severities of level 7 and N/A in accordance with NAVSEA’s Guidance on the Use of AM.

1-3 REQUIREMENTS SUBJECT TO NAVSEA APPROVAL

Any items contained in this document specifically requiring NAVSEA approval shall be forwarded to Naval Sea Systems Command, SEA 05T1, 1333 Isaac Hull Ave, SE, Stop 5142, Washington Navy Yard, DC 20376-5142 via the AM authorized representative. Subcontractors shall submit such items to the contracting activity in accordance with the contract or purchase order. Contracting activities and authorized representatives shall thoroughly review and make recommendations as to the acceptability of the item submitted.
