Metal Prusa
I know that this is an expensive, but I want to know if some had used metal parts instead of plastic. I already bought the bear kit (I haven't started to assemble it yet) I think that I can get an improvement if instead of using plastic for the Z-top and motor holders I use aluminum or even if I replace everything. I already quoted the z parts and I know that I'm talking about another ~$120 but after seen how fast and reliable can be just by using PA11CF I got curious regarding using an even stiffer material. Let me know if I'm just nuts and with ABS-GF or any other strong filament can achieve greater results than using aluminum.
Here is a quote from PCBWay for all the z parts of the bear kit, cnc job Aluminum 6061 - Bead blast + Anodized color(Black)

I don't know why you need metal unless you are doing lots of high temp prints in an enclosure. I was thinking of why printer parts were plastic and now understand that they are stable for most people. Depending on what you are printing with, you can print the parts in a higher temp material and replace the PETG parts. I am doing that with my print head and changed it to ASA from PETG.
It may be PCBWay that will 3D print metal parts from your files for a price. Check a quote on this for the printer parts. May get better metal for the same price.

Actually, I'm doing a lot of ABS-GF and ASA-CF and I had some issues when calibration Z because of the minor deformations of those supports.
RE: Metal Prusa
That is a good reason.
I have run into issues with Aluminium and thermal expansion but that was for much more precision than you will be printing. I would still look at the metal 3d printing services to see how much it would cost to get the parts 3d printed since it may be a better, more heat stable material. I would also be looking at the other components of the printer. Looking at the GT belts specifications, they have different belt material for higher temperatures (>85) and you may want to look at that as well.
