3D-Printed Circuit Boards, for solder-free printable electronics

Fpgd9Obh1Lwpqp5

3D-Printed Circuit Boards, for solder-free printable electronics.

Given the schematic for a simple circuit, make it a real circuit with the base components, some conductive thread, and a 3D printer. No solder, no etching chemicals, no sending away for anything.

This Instructable is to serve as the how-to guide for a 3D-printed electronic circuit library implemented in OpenSCAD, 3D-PCB.  I recreate the full replication process of a simple analog circuit of a blinking LED made from a few transistors, capacitors, and resistors, a single LED, and a AAA battery. I will review how to import the library, and use it to place components in OpenSCAD in a grid, and teach you the basic wrapping techniques for all the included features.

Also included is a more useful example of an LED flashlight.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
