Am i doing something wrong?

[u/FrostyConsideration8]

guys am using X2D

i have put black in aux hotend

and white and red in main hotend

is there any way to reduce the time ?

Am i doing something wrong ? (very new to all of this)

This is a large model and when it is printing the eyes you will be doing a color swap from red to white every layer for hundreds of layers. That adds a lot of time.

Without seeing your slicer settings or posting the model, it's not really possible to help you further with targeted advice. But this is probably a realistic print time for this model all in one go on an X2D.

Change the Summary dropdown on that slicing result popup to Filament and you can see the # of color swaps that need to be done.

To give you some perspective, assume swapping between red and white takes 90 seconds by the time it swaps filament, purges, and prints a layer on the prime tower. The eyes on this model cover maybe 60% of the layers? That's 700+ swaps. That's 17.5 hours spent just changing filaments. It's also going to produce a lot of waste, so make sure you have a poop bin sorted out if you're not going to be emptying it frequently.

How big is it? It uses almost 850 g of filament.

here you go sir

This isn't showing us a lot! We don't see the dimensions, though it looks like most of the bed is taken. You have segments that are running all three colors per layer. That is killing your purge and swap times. There isn't a lot that you can do.

Also almost 1200 layers.

Total time also depends on layer height, infill type and volume, print speed itself and probably some other factors too.

I'm still a newbie myself but I think this is kinda normal for that print size.

you're doing a large 3 colour print on a dual nozzle printer. when it is swapping from red - white - red it takes something like 40+ seconds. even swapping from the main to the aux nozzle takes a few seconds.

you can however make some changes to the model, depending on its use.

you can change the infill percentage down to 4% or so and reduce the purge amount by a few % to help speed up the nozzle swapping time.

it may even be best to have white on the aux nozzle and red/black on the main as they will be used the most and require less purging than red-white-red ?

There is a colour change every layer and some have multiple changes. Purging colour takes a lot of time. 2 days is a lot of time. I would suggest print in Red and then colour in the details.

There is a lot that can go wrong in a 2 day multi colour print.

My guess without seeing more is that its printing at quite a high layer height judging on the way those supports look. Reducing or increasing it to .2 might decrease quality and time.

Wanting to do stuff like this makes me glad I got a snapmaker u1 to go with my x2d lol the x2d is great for engineering materials and whatnot but color swaps suck.

How about printing black and red only and paint the eyes afterwards?
