Original Prusa i3 MK4  

Re: Original Prusa i3 MK4 or MK3s

Magic eight ball say “not likely”.

Re: Original Prusa i3 MK4 or MK3s

My inside source says that they'll be announcing a new software-programmable print surface that allow the user to select the surface texture for every print, thereby rendering the powder-coated and PEI print surfaces obsolete. Textured powder-coated PEI sheets will begin regular shipment at that time.

My source, Chad Prusa (no relation), is pretty sure on this one. He's usually reliable so long as he remembers to take his meds, at least since he got out of rehab last time.

The big hangup this time seems to be the Tesla delivery vans they want to use. Instead of setting dates and disappointing everybody, they're just going to wait until the Teslas show up before announcing anything.

Very funny...

Re: Original Prusa i3 MK4 or MK3s

I'll repeat what I posted in the other thread that went a bit off-topic.

Data taken from Wikipedia
2015: Original Prusa released (I don't know the month)
+ 6-18 months: Prusa i3 mk2 (May 2016)
+ 10 months: Prusa i3 mk2s (March 2017)
+ 6 months: Prusa i3 mk3 (September 2017)
+ 8 months: MMU2 (May 2017 - my estimate)
+ 4 months: ...?

So there does seem to be a product cycle of around 6-14 months for printers (10 months between mk2 and mk2s; 6 months between mk2s and mk3). Additional info that I would consider: marlin 1.1.9 is the final release for 8 bit (link), and on the blog-article on inconsistent extrusion (link) Prusa tested their printer using a Duet board (the photo in the article also shows other boards that are not mentioned by name). So that means they run other boards in a test configuration. The mk2 introduced the Rambo board, so already some time ago. Considering this, I would say that a mk3s does not seem impossible.
On the other hand, the issues with and redesign of the MMU may have delayed the planned printer's product cycle, so that is a counter argument.

There are also the rumors concerning Prusa and 3DWarf, so perhaps a Prusa branded-3DWarf is possible, but everything is so quiet on this that I don't think so.

But in the end, this is all just speculation... We'll have to wait till September. 🙂

Perhaps that's the reason that currently is "3days" for shipping on KIT MK3 version as they want as much as possible orders ?

The time between Prusa printer releases has been steadily decreasing to the point that we're approaching time inversion. New printers will soon be released before previous versions. In September, Prusa will announce the new Mk4 which will have been being available for 6 months. Pre-orders (actually post-orders) may will have been submitted starting 6 months prior. Those wishing to pre-order will be having had the opportunity to get in the queue starting 6 months prior to that date, at which point they will have been angrily posting daily. Their printers will ship the day before the announcement, but may be held up due to future supply chain constraints on the 2020 Haribo gummi bear production, in which case any printers received on release will not have been manufactured.

I can see why their shipping software is complicated.

No, man. Chad swears it's that software-configurable bed surface. The dude knows, man.

If anybody knows where I can get spare parts for my Mr. Fusion, I'm all set. I'm really looking forward to this release. It has been awesome. Too bad it's already obsolete.

Well, MMU is in the list, which is technically not a printer... 🙂 So it is not decreasing, rather fluctuating.

New printers will soon be released before previous versions. In September, Prusa will announce the new Mk4 which will have been being available for 6 months.

I wanted to add to my previous post that I'm not expecting anything spectacular that would suddenly make the others models obsolete or so. I mean, a board upgrade is easily retrofitted and - I could be wrong - does not impact quality much. If I could, personally I would not wait (I have to wait till New Year, but that is my personal situation).

Perhaps that's the reason that currently is "3days" for shipping on KIT MK3 version as they want as much as possible orders ?

I think they just managed to get rid of their back log. They did increase their production capacity (nice video on Youtube on that). Besides, advertising 3 days is one thing, but if you don't deliver on that promise it is also negative. Given the fact that many components are 3D printed and updated (new versions of the components), I guess they are close to the point where they can work with a minimal stock.

Did you check with that guy who printed the DeLorean?

😀 It looks amazing though...

Meanwhile, if you want to ask what is coming when, just ask them:

Re: Original Prusa i3 MK4 or MK3s

I suspect that they will release a new printer 2 days after I get my new MK3.

I can sympathize. The cell phone I've wanted all year is now $200 off and available, but new models are expected in 60 days.

Always a risk... but you cannot really plan for it.
I once bought a computer, thoroughly selecting components based on Intel's published timeline to maximize upgrade potential. Literally two months after I got it, they revised the entire timeline, killing any possible upgrade path I might have had in the process (and if I had gotten a lower model, I would have had an upgrade path).
When I got my camera, I waited for a new model to come out, but when it came out I decided the small functionality improvements were not worth the extra cost, so I got the old model. No regrets about that one. 🙂
At one point you just have to say "it is good enough": the device you get now does not get worse because something else comes out. But I understand you: we want our investments to be as cost-effective and sensible as possible.

Re: Original Prusa i3 MK4 or MK3s

I would say one thing: At least with this company, it appears there is usually an upgrade route.

Ain't technology wonderful? 🙄

Ain't that the truth.

Re: Original Prusa i3 MK4 or MK3s

Just my thought, is the next Prusa printer release will be Resin SLA. I don't have any facts just a wild guess.

Re: Original Prusa i3 MK4 or MK3s

Or a larger format. I think a 500mm x 500mm or larger would be a good idea.

Prusa's purchase of a resin DLP printers is not a secret.
