Comment Comment by jboirazian Conventional PLA. Since its the cheapest and surprisingly extremley stable for Ghz range RF applicationsI 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. parent jboirazian 2 years ago
