As others have mentioned plastic may not yield what you are looking for as even if it can withstand temperatures above espresso machine temperatures who know how the physical properties change close to that. Would you want a pf to start to soften at 100C and start to flex and shoot streams of 9bar hot water? Some form of milling/CNC would be a much more stable option especially for long term use. I have had the same thoughts as the OP though. I look forward to the day when I can afford a 3d printer that can work with metals.

I would strongly advise against this. While ABS in it solid form may have the capability to withstand the applies stress, a 3D printed (FFF) part will not. You are relying on the bond the material makes when melted a loosely attached to the previews layer.
You may find that machining out of aluminum is cheaper than a 3D print that is strong enough for your application.
