Change Nozzle Size Mid-Print

Bambu Lab Software Feature Requests
1

I print a lot of parts that involve fine detail, raised text printed on top of flat rectangles. To get the resolution I need for the text, I need to use a 0.2 mm nozzle for the print. Because of this, my prints take over 16 hours to complete. Most of that time is spent printing something that could be done with a 0.4mm nozzle or larger.

I would like to request a feature to be added to allow users to select a layer at which they would swap their nozzle. Much like selecting a layer to pause at.

I use an A1 so nozzle changes are not hard mid print.

If implemented, it would likely shave HOURS off of my print times. I’m sure many others would have a use for this.

Huge fan of this feature, missing a lot. Especially while swapping nozzles in A1 series is very convinient

3

Would be nice, but the device would probably have to recalibrate z offset after this. At least on one point of the hotbed.

4

This would be amazing. Quite often I am printing objects with text at the top and that is the only part I need in better quality and this would be such a time saver to be able to change the nozzle only for the top part.

It would be great if us H2D users could use 2 differently sized nozzles and choose which layers or features will print with one and which will print with the other.

I think the concern with swapping nozzles on a single nozzle unit would be handling the hot nozzles. While you’re ok with it - I don’t think Bambu would want to encourage that especially with the target market of most of their printers.

That said - I’m always a fan for having the option. I would think such a feature would probably need to come with a warning.

That said - I guess if you keep the bed hot - you’d have time to let it cool down, swap, and heat back up.

Would I be able to pause the build at a certain point, change nozzle and have the print speed lowered?

7

No.

The slicer is not capable of setting a nozzle change like this for single nozzle prints.

You pausing part way through to swap a nozzle will not change this and only ruin the print or damage the printer.

8

What if i split the model into 2 parts for text on a box like the OP’s example. Just set the offset for printing the next plate. Then I could change the nozzle and settings.

9

This. Print the text in a little “surround” that juuuust is big enough to hold it all together, then set up a pause - insert text - resume in the main print body. Tolerance it right and it’ll be nearly invisible.

10

The slicer will send the project in full the second time from the build plate.

This would drive the nozzle into the existing model already printed.

11

Are you trolling?

Have you never had to resume a big print from a half way failure? You can set where in the G code and layers to start printing from layer 120 or wherever you need to be and offset the Z axis to start printing at a certain height off the build plate.

Thanks Carbon Forge, You understand what I mean. With a little trial and error with a sample print you could print multiple times on the same plate if the settings were right to avoid collisions. Would need the build plate to stay hot though.

13

Trolling, nope.

Where are you seeing this option in Bambu Studio?

Please share screenshots and the process.

You speak as if this is a built in feature, I would love to see it.

14

I too would like to see where this option is in Bambu Studio.

15

I am in the same boat. I print bracelet charms. Most are generic shapes with some type of writing on top. The base is best printed with a 0.4 mm nozzle but the text/ top layers would look 10x better in a 0.2 mm nozzle.

unless i doble my print time and stick to 0.2 but I need my A1 to finish jobs asap.

16

same thought here, has this been implemented anywhere?
