Comprehensive List of common Acronyms and Abbreviations used in 3D Printing and Manufacturing industry


Rapid innovation and adoption of new technologies is driving major improvements in the performance of additive manufacturing (AM), also known as 3D printing. It is believed the Fourth industrial revolution has extensive dependency on fast-paced AM systems. Several 3D printing processes have been invented since its inception which is growing at fast-pace and terminology may be misused, thus creating confusion. We have created a comprehensive list of 3D printing and additive manufacturing related acronyms and terminology.
