Polyvinyl alcohol is playing a key role in the advancement of 3D printing technology. Researchers have discovered that PVA can be used as a dissolvable support material in 3D printing, making it easier to create complex geometrical shapes. The PVA support material can be easily removed by soaking the printed object in water, leaving behind a perfectly formed structure. The use of PVA in 3D printing has significant implications for the manufacturing industry, and is expected to lead to more streamlined production processes and improved product designs.
