Thanks for the response! I hadn't thought about using a coating post-print so I will look into that to see if I can find something that will work (ideally for more than one bake cycle but if it is a simple dunk to get ESD protection then that is do-able)

Hydrophilic surfactants depend on humidity to dissipate ESD.  A hot oven usually has near 0% relative humidity.  If you use a coating, it needs to conduct independent of humidity.

Learn something every day -- I wasn't aware this stuff depended on humidity (though I was well aware humidity in a hot oven tends to be very low).

<p>I am trying to develop a process to print fixtures/jigs that can withstand a convection oven temperature of 165 °C. The tricky thing is that these parts have to be considered ESD safe (surface resistivity of <span class="math-container">$10^4 - 10^11, with 10^5 - 10^7$</span> being optimal).</p>

Please prepare a list of materials that meet your needs. With that list, we might suggest various manufacturing methods. It may be that your can print something like PEEK or PPSU in near-net-shape, and then machine it to your tolerances (if needed).

Material selection is where I am struggling right now, from my research PEEK has a surface resistivity of about 10^16, which is considered insulative so it will not provide ESD protection against the electronics I am working with

# 3D printing ESD safe/high temp parts

(Asked by: username_0 on 2021-07-09)

I am trying to develop a process to print fixtures/jigs that can withstand a convection oven temperature of 165 °C. The tricky thing is that these parts have to be considered ESD safe (surface resistivity of $10^4 - 10^11, with 10^5 - 10^7$ being optimal).

I have found tons of options where I can get one property or the other, but have had little to no luck finding any companies that are able to fulfill both requirements.

Also: the parts that I need to print need a high level of detail, (X/Y/Z accuracy of at least .005", ideally tighter) so from my experience, I have focused my efforts on resin printers, but am also open to filament printers if they can provide the accuracy I need.

If anyone has any suggestions on printers to look into or companies that I may be able to reach out to for an inquiry it would help me a ton.
