It is now easy to make your own custom solder-free circuit boards through 3D printing. An independent creator on DIY website Instructables has 3D printed its own personally designed circuit board. The circuit board was created in CAD, printed, and its trace channels lined with conductive material. Once built, this circuit board does not require solder to establish working electrical connections, an easier and cleaner way of building your own circuit boards. This is perfect for hobbyists but also indicative of the many custom applications 3D printing can have in technology development.
