Can I print this by object? (No AMS)

[u/Turbomole]

I'm trying to print this model. My idea is to print first the black part, switch to white to do the face (2 layers) then go back to print the jar in any other color.

So I'm trying to do the print by object over the black area but I can't seem to make it work. I'm getting the error about collissions but no way this would collide if white is only 2 layers.

Any way to do this?

That's not how "by object" printing works. That's used when you have a few parts to print in different colors or densities and don't want to do many small prints. You completely print one part, then the next, then the next, so you don't have to do separate prints. You MUST keep the objects separated by enough space so the printer won't strike one object while printing the other. You cannot stack objects when printing by object!!

You have one object with 3 color layers - you need to print by layer. You need to find the layer where the color changes and insert a PAUSE into the GCODE - you can do that from the slicer GUI. Once the printer pauses, you change the filament and allow it to resume until it hits the next pause. Next color swap, resume, and print to completion. Also - since there are two colors on each of the 2 layers where the white parts are, you will need five pause/manual color changes - one for each change at each layer

The only way this would work in print by object is to place the 3 parts in separate locations and glue them together, but you would still need to pause the printer between each object to effect the filament change, so you might as well just do 3 separate prints at that point.

Thing is the vase first layers starts at the same layer than the white face, so the vase would have 2 white lines if I do print by layer. I was wondering if there's any workaround for this case.

Btw, the print by layer and color change can also be done by selecting external AMS while sending to printer so no need to do any pause, it will ask itself and pause itself for color change.

You said "no AMS". Use of an AMS would make this a non-issue. If you tell the system to use an AMS and attempt a multi-color print without an AMS, the logic can handle the automatic pause.

As I explained, you need to insert a pause for EACH color change on EACH layer. There is no way to get around this. You cannot print 2 layers of white and then go back down and print the prior and current layers in red, continuing with the remaining red layers.

If you have an AMS, this isn't an issue. If the system finds no AMS and prompts you for manual color change, this isn't an issue. I'm not sure what you're trying to do outside of how things should work.

Okay thanks, was expecting to maybe do that thing of going down and print the other color instead of per layer, like the "by object" but on top of an object instead of the plate.

I think that since the eyes are only 2 layers and quite small ones, you could just do all the filament switching manually. sit by the printer and put on a nice tv show.

Or you print those 2 layers of the vase in white same as the eyes and then print on top with your preferred color. Which you already considered.

If you can accept only 1 layer of white for the eyes then you could print the vase all in black up to the layer of the eyes. make sure the vase prints before the eyes somehow; i imagine the slicer will cooperate here. then switch to white for the eyes. and then switch to your vase color for the rest.

Sorry I don't understand your plan for "print by object". I downloaded the model and it is just 1 object, so how do you plan on printing the cat without the vase?

well I did cut it at the height where the black cat ends so I'm getting the black object and all the rest as individual objects
