The APTA Emerging and Innovative Technology Committee met yesterday to discuss ongoing work this year related to both Senior/Disabled Assistive and 3D Printing Technologies.  The session on 3D printing was excellent, with new participants chiming in with great ideas for what the committee could achieve in this topic.  From prototyping components, to Buy America support, to solving problems with older parts, 3D printing has huge promise for the public transportation industry.
