Colorfabb XT, i saw they put it in a dishwasher to change the color at 70°c [...]
It must really be at 70°C as I tested it at 65°C and it neither changed color nor opacity.

It seems that what you want is ABS.
No i don't want ABS because of the fumes mainly.
I also believe that nylon is much stronger than ABS. I don't know about XT.
I'm currently testing colorfabb regular filament and it's going pretty good.
My main concerns are:
1. Fumes toxicity?
2. Maintenance of the printer if you use this material.
I'm using a UM2 by the way
As I said elsewhere, Taulman nylons have no toxicity. The key to maintenance is to ensure you buy their newly made nylons after they retooled to a nominal size of 2.85mm vs the previous tooling of 3.00mm.
The previous nylons have a strong tendency to jam in the Bowden tubing.
You need to trust your supplier on this and stress that you want 2.85 not 3.00. The problem is that both sizes have 3.0mm printed on the reel label. If they sell you old stock you will be stuffed. Eventually one can surmise that this old stuff will work itself out of the supply chain although irritating that Taulman did not re-label.
Apart from this point my assumption is there is not really any maintenance.
The above does not apply to their t-glase nylon as they say this was always manufactured with the new tooling. For clarity it certainly applies to 618 and 645, do not know about Bridge.
Thanks I will have to ask the suppliers then because i don't want to spend money on a filament that will not work good on the printer.
Didier,
I print a lot with XT and really love it.
It's very strong and has no fumes like ABS or Nylon, you can compare the fumes with PLA/PHA, almost nothing.
Also, I never had a clog of any kind with it ans also never have any problems with the bowden tube.
A little instruction I wrote to swap between XT and PLA/PHA filaments:
Thanks for the tip harold
Would you say that XT is strong enough to manage some friction? Like the piece for the lawn mower will have (it's a pulley)
Your welcome Didier.....
XT can handle some friction, of course it always depends on the kind and amount of friction.
The filament has, from my opinion, better properties than ABS.
I'm in the process of rebuilding my UM1 into an alu frame construction.
All parts are printed with XT, even the extruder and hot-end mount.
Even if it's unsure that XT will hold as a pulley for your lawn mower (I think it can), it's definitely filament you should have for strong, heat resisting parts.
I tried a few meters of HIPS (even more heat resistant than XT), but the fumes where killing, even worse than ABS.

XT is easier, prettier, and has a higher glass transition. Nylon is a pretty cool material, but more specialized for simpler parts that need to be strong and a little flexible.
I would do XT.
