Here we go, I can maybe get nylon done here via multijet fusion for not too much money: jlc3dp.com

After checking price, the body part would be 43 dollars, in nylon. The top part only just over a dollar. That is too much for me, will try lathe in delrin first. Maybe 7 or 8 dollars in material. Will report back on that. Will also look at modifying my printer for nylon.

Dan, just wondering why the call for Nylon, from what I know of it Nylon is very hygroscopic, is that not a big issue in this application with it being submerged in water.

Evengravy,


I have been printing cells from both PETG and PA6CF. The PA6CF cells always weep through the material and bleed pressure, leaving water on my workbench. No matter how hot the print or how much i overextrude to fill any microscopic gaps. PETG has held up well and proved to be water tigh even under pressure. I ordered white and clear PETG last week and plant to print the stacked cell device that Stan and McKane describe next. I found derlin filament but it sounds like a headache to print so I wont go that route unless I run into unforseen issues with the next few PETG prints. Now I just need to find some 430 to wind my coils with.

Cheers. It's easier for me to go delrin as I have the machinery to do it here (lathes cnc etc.) But might try PETg also, have some here also. Thanks for the info, appreciated
