3D Printer Creates Patterns Smaller Than a Blood Cell

Jun-27-15 A 3D printer able to print objects smaller than a red blood cell could simplify the process of creating circuit boards and other electronic prototypes.

The printer, created by a team from the Ulsan National Institute of Science and Technology, is able to create a variety of ultrafine patterns, including rounded walls and helix-shaped pillars. The fine level of detail is achieved by using an electrohydrodynamic inkjet loaded with special, multiple function inks that can be layered to create specific shapes. The process works at room temperature, and the patterns are as small as 0.0001 mm, which is thinner than a red blood cell.

The development team believes the 3D e-jet technology could be combined with conventional 3D printing to create highly integrated devices, and could have applications in next-generation electronics.
