As advances in materials and speed are made in 3D printing, the opportunity to use these processes for low-volume production is now very real.  One of the primary benefits of this process is printing parts as you need them (just-in-time manufacturing).  Parts can be printed digitally allowing for the ability to make changes during production without incurring delays or tooling modifications.  Another strength of this process is the ability to make highly customized parts without a need to modify tooling.  HP’s revolutionary Multi Jet Fusion (MJF), 3NTR’s Elastomeric Fused Deposition Modeling (MMFDM), Direct Metal Laser Melting (DMLM) and Selective Laser Sintering (SLS) are all good candidates for producing production quality parts.
