Conductive fabric laser cutting:
It is important to take all the security considerations to laser cut conductive fabric as it is mainly fabricated with silver which means a reflective material. We used double sided fabric in one side and cover the other side of the conductive fabric with paper.
- Iron fusible interfacing textile (entretela in spanish) to stretchy conductive fabric. Avoid high temperatures and spending too much time over one spot or you will damage the textile and it will not be conductive at all. ( It happened to us ). Leave the protective paper.
- We used a LaserPro – Spirit machine which has a metal honey comb table useful for small cuts that you don’t want to loose. For cutting textiles it is very important to prevent the fabric to move or to wrinkle, that’s why we added a 3mm plywood as a “second underneath table”.
- Put the conductive fabric over the plywood with the fusible interfacing side to the top. We added a white paper over it in order to double avoid reflections from the silver, but the paper was obviously burned very fast and fire appeared some times (!). So just leave the fusible interfacing to the top and that’s it.
Comments and recommendations:
- We are using stretchy conductive fabric from Plug and Wear online store, adding fusible interfacing will obviously reduce it’s stretchy characteristic. You can also try making some patterns like Nadya Peek in her “Talk to my shirt” project.
- The longer the distance for your conducive fabric traces, the wider they should be.
- Parameters for Epilog laser cutting machine: speed – 10%, power – 100%, frequency-1000Hz.
