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 idealorientation had to be manufactured in 3 pieces and then welded.However, the risk of component warp or misalignment duringwelding is reduced significantly from the traditionally manufactureddesign due to the reduction of welds and low-risk weld locations.Cost savings and further risk reduction could be had with removal ofthe welding step (using a printer with a larger build volume or usingother orientations which may require further post-processing).
Testing/Schedule: Full functional, dimensional, and on-platformtesting could not be conducted prior to the Print-A-Thon.
