FY17 Department of Navy Additive Manufacturing Print FY17 Department of Navy Additive Manufacturing Print - - a a - - Thon Thon Small Arms Support Component Small Arms Support Component - - MK93 STOW LOCK MK93 STOW LOCK Org Logo Here Many small arms support components are traditional- ly manufactured from multiple welded machined and sheet metal pieces. Misalignment of the pieces and/ or warping during welding can bring the final compo- nent out of geometric specification and result in fit is- sues which impact use of the overall system. In the past, orders to vendors not experienced in the manu- facture of these components lead to high initial scrap rates and back-and-forth dialogue before the part can be produced within specification. In-house metal AM has the potential to reduce lead-time significantly when responding to a rapid, low volume component demand. Transition: Transition Customers - MK93 Users: US Navy Marine Corps Naval Special Warfare (NSW) US Coast Guard Timeline Potential: Short Term (Testing Required) Business Case: Current, Traditionally Manufactured: 60-90+ day Lead Time $130 / part in orders of 50+ Additively Manufactured: 5-10 days $660 / part in orders of 1 Warfighter Support: A faster end-product turn around time for urgent, low volume demand. The Technology: System: 3DSystems ProX 300 Powder Bed Fusion (PBF) Material: 17-4PH Stainless Steel Challenges: Printer Size Limitations: The chosen component in the ideal orientation had to be manufactured in 3 pieces and then welded. However, the risk of component warp or misalignment during welding is reduced significantly from the traditionally manufactured design due to the reduction of welds and low-risk weld locations. Cost savings and further risk reduction could be had with removal of the welding step (using a printer with a larger build volume or using other orientations which may require further post-processing). Testing/Schedule: Full functional, dimensional, and on-platform testing could not be conducted prior to the Print-A-Thon. Readiness/Sustainment Concept Readiness/Sustainment Concept
