and also had to develop new methods to print electronics rather than use the techniques commonly used in the electronics industry.
Mcalpine said that one of 3-D printing's greatest strengths is its ability to create electronics in complex forms.
Unlike traditional electronics manufacturing which builds circuits in flat assemblies and then stacks them into three dimensions 3-D printers can create vertical structures as easily as horizontal ones.
Mcalpine said that he does not envision 3-D printing replacing traditional manufacturing in electronics any time soon;
In this case the researchers were able to custom 3-D print electronics on a contact lens by first scanning the lens and feeding the geometric information back into the printer.
