Any info on the Prusa XL?  

RE: Any info on the Prusa XL?

For those who aren't following closely, the upgraded Prusa XL allegedly does include tool changing.  Sweet!  I presume that will help keep its relevance for quite some time into the future.

RE: Any info on the Prusa XL?

They are similar, but Prusa take it to the next level with 5 heads and less of a builders kit.

My hint: have a look to E3D toolchanger.

It is already in use in the market.

You will have a fair understanding of what can be expected from the XL toolchanging system (even if, yes, Prusa will customize it to its personal needs, convictions and vision)

I think we are safely beyond 'allegedly' now 🙂

RE: Any info on the Prusa XL?

Hopefully so!  Believe me, I want it to be true.  However, those keeping score know that not 100% of all prior announcements were ultimately delivered.  So, at least for now, I'll stick with "allegedly". 

RE: Any info on the Prusa XL?

I would say they are more reliable than most other printer manufacturers.

Agreed!

RE: Any info on the Prusa XL?

Features are actually over-delivered in general.  They keep on adding things to the PrusaSlicer and firmware updates for old machines.  My MMU isn't as reliable as it should be.  I thought that I heard on one of the podcasts that they talk about color and material changes possible with the tool changes.

I'm very disappointed in the price. I've been looking at CoreXY printers and was hoping to get an XL. But I can't justify spending that kind of money on a hobby.

I was expecting something way cheaper than that. 

I am a bit confused on the public target. If the XL shares the same options / interfaces with the Pro AFS then why would people spend more money on the PRO AFS version? 

It's not like you can't build a print farm with the XL version.

 

 

Prusa states that they are surprised by the large number of pre-orders, so even though some are disappointed, many of us are not.

Well, I've pre-ordered a 5-head machine, so we're far beyond "allegedly".

RE: Any info on the Prusa XL?

Compared to the feature list, this printer is well prices and on the cheap end.  

RE: Any info on the Prusa XL?

I am very tempted to preorder a 2-head XL, but it’s way beyond my current needs.  If I’m spending 2000US on a 3d printer it will be resin rather than filament.  And if it comes to that, damn me if you must, but a cheaper Anycubic might be “good enough.”  I love the whole philosophy, engineering, and pluckishness of this company though and hope for a slightly less expensive resin solution from Parusa down the road.  (Kinda like the mini is to the i3)

RE: Any info on the Prusa XL?

Indeed! I'm hoping for a Prusa resin printer down the line as well. FDM still has it's place for me - each solve a different problem.

RE: Any info on the Prusa XL?

So in bonkers print job land, it seems (if a slicer could support this) you could have a multi-material print that used custom dissolvable support for each material type (like say HIPS and PVA supports for different parts of the model) - to make that kind of setup sane a small display on each head that shows the currently loaded material type would prevent stupid errors (or reduce)

RE: Any info on the Prusa XL?

You could, actually, have multiple types of support material on such things as the MMU2S, Mosaic Palette, or even that rabbit feeder thing.

However, I've yet to come across any case where more than one type of support material is needed.  I regularly use generic PVA for PLA and ABS, and occasionally for PETg and never had issues.

Are there cases where different support material types are needed?

RE: Any info on the Prusa XL?

I have an MMU2S. The only thing that the prusa slicer allows to be use in the "support material extruder" is dissolvable materials. Even if we ignore the cost and shorter self life (due to their humidity sensitive nature) and the fact that they end up messing the wipe tower, i still would like to be able to use pla ,for example, as a support material or even sometimes an older filament of any type. This can be achieved at some point if you "claim" for it to be soluble and play with the settings but i would like to spend less time playing around with possible settings and actually printing. I'm currently avoiding using MMU2S with soluble supports (unless i really need to) but the multiple head approach it seems to me a nudge to a better direction. Each head keeping a specific temp (no delays for dropping and increasing temp PLA to ABS or PC is a rather big change in temp), no contamination, no throwing away support material in a messy wipe tower etc. And actually may it will be easier to implement using any kind of material for support.

I fail though to understand what a small display to the head will offer (other than added cost). The type of material can easily be displayed in the main screen.

I have never had the need for more than one, but I am interested if anyone has had the need.  I find the need for alternative support materials to be of limited use.  That being said, I will experiment more when I get my XL.  

RE: Any info on the Prusa XL?

The XL uses belts for the x and y axis.  You can't scale a printer larger than the XL without losing the belts and going with some sort of screw or steel wire drive, both of which require redesign of the basic frame.  If you try to, you are subject to all sorts of vibration or belt stretching.  I believe even 400x400 is pushing it.

RE:

Am wondering:   How does the multi-head Prusa XL compare to the single-head but multi-filament Bambulab 3D printer?  I guess the Prusa XL multi-head wouldn't have to purge as much when switching between filaments?  Resulting in less waste and theoretically faster prints?

RE: Any info on the Prusa XL?

I do not think it requires little, if any, purging to change heads.  I saw it in action at a conference, and I never saw any, but then again, I was not looking for that.

RE: Any info on the Prusa XL?

The videos from ERRF including one I ttok and posted on the “Delays” thread, there is still a purge tower.  Small by comparison to a Palette or the MMU2.
