I want to contain a very small PCB (roughly a square centimetre) in a casing. For demonstration purposes I want to 3D print a couple of those casings as well.
The most obvious method available would be using ABS for the printed casings. However, nylon appears to be smoother and tougher. Those traits are often a plus during demonstrations. However, since the PCB contains a S band antenna I'm slightly worried about the RF properties of the material used.
Are there any downsides to switching from ABS to nylon that I'm not seeing? I'm especially interested in the RF characteristics in 2-4 GHz range. Cost is not an issue.
