Barriers to 3D printing in Mining, page-127

Whilst this is a 2014 article (probably referenced here many times before ) ,

the "science ,technology and speed " that Aurora are bringing forward in the 3D manufacturing process , will also be scrutinized by the chemical metallurgists .....as to where strength and heat additives like niobium/vanadium/scandium/zirconium/hafnium can be added to , or substituted for ( where necessary and applicable )to improve the performance and longevity of machinery or parts thereof .

All about cost , performance and speed ----but we are in another revolutionary period in transportation/communication/medical science/exploration and mining techniques ,largely ( but not exclusively) brought about by the dynamics of the Chinese economy .
The changes in the next 10 years will likely be extraordinary , and Aurora is hopefully going to be a big part of it .
