Among the new technologies currently positively used in manufacturing are augmented reality/virtual reality, 3D Printing, artificial technology, and nanotechnology. An AR|HUD system displays perspective-accurate surrounding information for a user to visualize 3D.Digital instructions are more detailed due to workers being allowed to see moving digital pieces being projected onto the work surface, reducing errors and stress.Industry 4, also referred to as the Fourth Industrial Revolution or 4I, is the next phase in the digitization of the manufacturing sector.Personalization and customization of products can be easily enabled with the low-volume production capabilities offered by on-demand additive manufacturing, creating an object by building it one layer at a time. Burst pressure tests on small numbers of products can identify weak points in product materials that could compromise performance, quality, or safety. AI is designed to accomplish tasks without explicit programming instructions.Nanotechnology is manipulating matter on a near-atomic scale to create new structures, devices, and materials.
