3D printing, also known as additive manufacturing, is a process for creating three-dimensional objects from digital files by laying down successive layers of material. It allows users to turn any digital file into a 3D physical product and offers immense customization potential. 3D printing offers businesses unique opportunities for customized marketing and promotional items, as well as interactive designs, while also allowing manufacturers to produce complex shapes and parts not possible with traditional methods. The versatility of 3D printing continues to expand across industries such as healthcare and manufacturing.
