In the recent article “Lockheed Martin Looks to Catch Up in 3D Printing”(http://advancedmanufacturing.org/lockheed-5ps-additive-manufactuirng/), an overview is provided of a seminar in which Robert Ghobrial, the additive manufacturing lead, spoke. Robert Ghobrial was clear that while Lockheed Martin is still exploring 3D manufacturing and the most effective ways to use the new technology, they were making great headway, and had already seen some recent successes. Ghobrial also provided what he called “The 5Ps of Additive Manufacturing”, which outline how additive manufacturing can help aerospace, defense, and other businesses. The 5Ps are:
- Proposal: “3D printing can make giveaways at trade shows; architectural and space models; and aid in customer/client communication.”
- Prototype: “3D printed prototypes help with design validation and proof of concept development.”
- Procurement: “Can we make something vs. buying it?”
- Production Support: “3D printing can support production by helping make assembly fixtures, manufacturing tooling, production templates, inspection fixtures and machine safeguards.”
- Production: “AM can produce end-use parts; make parts on demand for spares, warranty and repairs support; and even manage obsolescence.”
These 5Ps provide all of a unique perspective into some of the ways many businesses may be able to employ 3D printing. How effective will additive manufacturing be in the long run? Only time will tell.
