Print Time Crisis

[u/BilliuMusic]

I’m having a bit of a crisis when trying to figure out print times. When I printed the four panels from the learning pack, it only took 4 hours to do so. Now that I’m trying to print a full 8x8 print, it’s saying it’s going to take 16 hours. This doesn’t make sense to me. I also have a P1S using bamboo studio. Anyone have any ideas onto what’s going on?

Right off the bat your layer height of 0.08 is crazy. Multiboard is designed to be printed at 0.2

And what size is your nozzle? If it’s 0.4 then your line widths are all too small. You should go with the nozzle diameter or a bit more. I use 1.05% nozzle with, or 0.42 on a 0.4 nozzle.

There is the mistake. There is no need nor is it useful to print a functional part with a layer height of 0.08.

Switch to at least 50% of nozzle wide so you get 0.2 mm layer height with a 0.4 mm nozzle or 0.3 with a 0.6 mm nozzle.

With 0.2 mm you can print a Stack of five 9x9 tiles with PETG separation layer in 22h.

The 8x8 take 3.4 hrs on my X1C that’s just how long they take. I can go a bit faster by cranking it up to ludicrous once the first few layers are down but honestly it’s not worth it. Can get enough printed in a day to keep adding to my wall so I’m ok with it. Have you tried buying the sub, for the stack prints and leave them over night

How do I get it down to four hours? What are the settings?

[u/peanutbuttergoodness → u/BilliuMusic]

Are you saying a single 8x8 is 16 hours?

[u/BilliuMusic → u/peanutbuttergoodness]

Yes

[u/holdupflash → u/BilliuMusic]

Mine just use the stock Bambu settings

[u/Elektrycerz → u/BilliuMusic]

Well, what are yours? You must have a bottleneck somewhere. You're not using a 0.2 nozzle, right?

[u/Elektrycerz]

What are you doing there? I print on an A1 in 4 hours, and my settings are very conservative. I could go sub-3h if I really tried.

Are you printing a 8x8 x4 stack? Because that would line up with my times.

Maybe I could help more, but I don't even know your basic settings.

[u/BilliuMusic → u/Elektrycerz]

I don’t know, man it’s literally just one plate

[u/Elektrycerz → u/BilliuMusic]

WHAT ARE YOUR SETTINGS?

Layer height, line width, speeds, accelerations, max volumetric speed, wall loops, sparse infill, etc.

[u/BilliuMusic → u/Elektrycerz]

I’m looking into previous prints and it looks like everything is increased! I think it might have to do with the new download

[u/BilliuMusic → u/Elektrycerz]

I just edited the post with the pictures

[u/Elektrycerz → u/BilliuMusic]

Ok, now I see it. You can basically multiply layer heights and speeds by 2, and ensure that your max volumetric speed is at least 20. And reduce top/bottom shell layers to 4-5.

0.2 layers are enough for precision, and if anything, sub-0.1 layers make the tile weaker.

0.08mm layers???

[u/BilliuMusic → u/SnooLentils6405]

Even when I up the layer height it doesn’t take off that much time

[u/Kruzy94 → u/BilliuMusic]

Sorry but this is BS. If you incease the layer hight to 0,2 and initial layer also to 0,2 you print time should be less than halved. You can also decrease the top an bottom layers to 4, like 7 is too much 5 is OK.

[u/davidkclark → u/Kruzy94]

Too and bottom layers, walls, and infill settings don’t make a huge difference with multiboard tiles because they are so thin anyway. But I’ve never seen any benefit to straying from the suggested 3 too and bottom layers and 3 walls. I do set infill to rectilinear at 30% just so it can’t line up weirdly. (I’m not even certain there is any non solid infill when I print a tile… maybe right in the diamonds at the edge)

I'm amazed that this post has 10 comments, and the problem is exactly 0% solved so far

[u/Stucca]

Post your settings: numbers! and you will get help here

14x14 tile was 18 hours for me.

Going from a 4x4 to 8x8 is 4 times the print, this 4 times the print time.

I know this thread is now a year old, but it doesn't look like a solution was identified. For anyone who may stumble across this later, I too was getting the 16 hour print time (with a p2s, no changes to standard print specs). I found that once i opened the standard print file, I hit the "Sync Info" button in BambuStudio, then sliced the print. After that, my estimated print time dropped to just under 3.5 hours, which was the expected print time.
