The US Patent & Trademark Office today published a series of new patent applications from Apple, and one of them is an inkjet printer for printing on a 3D object.
Inkjet printer creates a digital image by propelling droplets of ink onto paper, plastic, or other substrates. However, inkjet printers may also be employed for other purposes. For example, inkjet printers may be employed to print conductive ink. Conductive ink is a type of ink that includes conductive particles (e.g., powdered or flaked silver particles) therein and it may be used to form circuits or perform related functions.
