3D Printed Carbomorph Circuit Boards

Electrically conductive ABS-based carbomorph filaments have started to make an appearance on the market. This development in 3D printing can allow makers to quickly produce custom circuit boards, electronic devices and game controllers that can, for example, perfectly fit a specific hand shape. 

Although this type of 3D printing method requires slightly more skill due to the requirement to use dual extrusion methods to produce integrated devices, these technologies are now within reach.

The first generation of electrically conductive materials used finicky polycaprolactone polymer mixed with conductive carbon black powder. The introduction of conductive ABS-based carbomorph materials that are easier to work could kickstart a revolution in home-built consumer electronics fabrication.

At Swansea Universities Welsh Centre for Printing and Coating these materials are being investigated to produce simple yet important integrated machines. The team has determined that by printing different features, carbomorph can be used to detect: changes in temperature, when water is placed onto it, applied pressure, whether a device is being flexed. … (Read more)
