DoD Sites and Platforms:•US Navy: TRF Kings Bay, NUWC Keyport, NFPC Philadelphia Detachment, NAVAIR China Lake, Portsmouth & Pearl Harbor Naval Shipyards• US Army: Anniston & Tobyhanna Army Depots• US Air Force: OC-ALC,

Other Government: • DOE, NNSA – Honeywell FM&T• NASA – Marshall Space Flight Center

Technology Transfer:•Inserted 12 pieces of ADF-RP equipment into DoD Maintenance facilities and 12 pieces of ADF-RP equipment for initial piloting at industrial partners - conducted >68 case studies to date

Problem: •Military depot facilities need fabrication processes and engineered materials to build or repair hard-to-replace legacy parts •Need to reduce long-lead-times for cast parts with unavailable data packages through use of rapid molds and patterns•Need to reduce long-lead-times for other parts with unavailable data packages through use of ADF-RP processes

Technology Application: •ADF-RP processes include laser sintering (LS), electron beam melting (EBM), stereo-lithography (SLA), fused deposition modeling (FDM), direct metal deposition (DMD), and ultrasonic consolidation. •Objective is to install rapid tooling capability in at least one maintenance facility•Industry/government Team pilots the building of net-shape and near-net-shape parts, directly or indirectly using ADF-RP,in parent alloys and engineered materials, evaluating materials and process performance parameters

Readiness Benefits:

Cycle Time: >280 weeks of cycle time savings*

Cost: >$4.5 MM in cost avoidance*

Reliability:Parts verified by CAD, RP models, metallurgical & performance testing to spec

Availability:Continuous improvement - key enabler to system maintenance turn around improvements

Laser Projection of CamouflageLaser Projection of Camouflage Patterns Patterns

✔ Problem:● Every system repaired or fabricated at Tobyhanna AD is painted by the Paint Shop in the Mobile Equipment

Refinishing Branch, a historical bottleneck to system flow. ● Chalking of the Camouflage and stencil patterns is a manual method dependent on the skill of the technician. ● Cycle time reduction is required to make the painting operation more efficient and to reduce the disruption of

the product flow while increasing quality. ● A method to reduce dependence on the skill of the technician and to reduce the time required to manually chalk

a system and to change to another system is required. ✔ Technical Approach:

● Demonstrate a system and techniques of Laser Projection Technology from Assembly Guidance. ● Full setup by a trained shop person (30 minutes training) is less than 2 minutes, each dimension thereafter is

available in less than 4 seconds, and low accuracy coverage of five sides of large structures can be accomplished with two projectors, each covering 2 1/2 sides. Subject application was a shelter.

● The system can also rapidly change between product systems like shelters, trailers and vans. (Would require building models and digital data package for each model.)

● Development tasks in bringing the commercial technology to a production level for maintenance activities include: data creation, process configuration and new reference targeting methods.

✔ Projected Benefits:● Delivery of multiple Laser Projection heads and a Lap Top Computer plus control software. The hardware will

also include any electro-mechanical devices necessary to facilitate the rapid change between systems. ● $35k savings for one shelter application● a Laser Projection System can reduce the time to chalk the camouflage pattern by .5 hours. This does not

include the stencil package where the Laser projector would eliminate time required to measure for the location of the stencil. Therefore the payback on 80 items would be one week. Extrapolate that to a year at 80 items
