Conventional PLA. Since its the cheapest and surprisingly extremley stable for Ghz range RF applications I recommed you to read the research paper "Measuring the Electrical Properties of 3D Printed Plastics in the W-Band " (https://scholarworks.uark.edu/cgi/viewcontent.cgi?article=10...) It was really useful for us when developing our lens with an FDM printer. Be warn that it does require an infill of 100% , so it will be quite heavy. |
