High temp print head?
The multi-head nature of the XL makes many possible upgrade options possible. Any word from Prusa on heads they are planning to offer? The first one that I want right now is a high-temp head. Something that can approach 500C melt zones for exotic materials. Can probably do it myself swapping out plastic for FDM metal parts and upgrading the cooling system but this seems like such an obvious thing I was wondering if Prusa had plans to sell one.
RE: High temp print head?
My understandings is that at Formnext 2025 Prusa Announced a Hight Temp Hotend for the XL. Not sure if anyone and confirm if this is true. It would be great to have some upgrades for the XL. I know they released the Hight Temp for the Core1. Appears the Core1 and the XL use a different Hotend mounting system so they are not interchangeable.

RE: High temp print head?
I don't think a HT hotend for the XL was announced. It was "high temperature for the Core One family, silicone for the XL". See Prusa's blog post: https://blog.prusa3d.com/prusa-at-formnext-2025-indx-core-one-ht-hotend-silicone-dryboxes-and-more_125127/
There has been disappointment about this before; see this thread for example: https://forum.prusa3d.com/forum/original-prusa-xl-tool-changer-general-discussion-announcements-and-releases/ht-hotend-for-xl-why-not/
If it's any consolation, the high temperature hotend for the Core One family has not yet materialized either. It has been in "notify me when available" status ever since it was announced.

According to Tommy, the delay has been caused by the Bowden bend and Nextruder not being able to handle brittle filaments like PPA-CF and PPS-CF (for example). They had to redesign that and the bogie arm (which has had a community mod available for brittle filaments for quite some time).

Ultimately, these reasons were what prompted me to modify my XL as well.
When I was looking to buy an XL with an enclosed enclosure, the enclosure itself was what put me off the most. My second concern was the brackets that run from the printer to the toolhead.
After a year of work, this is what I came up with:
A horizontal drag chain mounted in stages. For now, it only works with two or three toolheads, but I’m currently designing a version for all five. Why did I do this? Because I wanted a more compact and aesthetically pleasing enclosure. A lower and deeper ceiling height reduces the volume that needs to be preheated. I liked the Prusa MK4 enclosure best because I was able to extend the profiles very easily.
The original goal was to convert the Prusa XL to HT and then use that knowledge to build the Core One on top of it. Now it’s turned out exactly the other way around, and I’m glad about it.
PPA-CF can be printed with the Prusa XL—I've tested this successfully, and I'm sure others have as well.
