How to prevent multi-part prints merging into each other?

So I’m trying to create a basic keyring for my dad for Christmas, it has a black base and then white text on top. I would like the base to have an ironed finish and then the text to print directly on top of that. From my previous experience using Flashprint this was never an issue, however with Bambu Studio it seems to imprint the text into the base when slicing. I don’t know if it does this to try and increase the strength of bond between the two parts or if I’m missing a setting somewhere?

Anyone else have this issue? It prevents the base getting ironed smoothly because it has to iron around the text imprint which ends in a less than impressive finished product

EDIT: forgot to add this isn’t a numbers issue as I have all the measurements right to make sure the text height is placed mm perfect

Hello,

I think this might solve your problem but if you can post photos it would help us out.

You want to use a height range modifier, set your mm range of your part and turn iron on for all solid layers in the modifier objects settings.

( Sample photo part was @ 3 mm in part height )

Ironing type = All solid layers in the layers objects setting.

Hope this help you out with dad’s Christmas project :grinning:

Hi there, thanks so much for the reply. Am I being stupid because I can’t find that height range option anywhere?

Just right mouse click on your part then you will see the drop down menu.

Still doesn’t seem to do anything, what exactly does the heigh modifier range do?

From the example you showed there, I want to iron the square base then print the text on top in a different colour, but when I do it the slicer seems to start carving the shape of the text out of the base and then does the ironing around the imprint. Then it will change colour and finish off the text

So the cube sample is 3 mm to the top surface not including the text height so you would put 0 to 3 mm in your modifier.

This will also not iron your top letters but you can change that also in the other settings.

Is your part text sunk into the part ???

See if you can find a u-tube video on PrusaSlicer on modifiers this will help you out to understand more about using them.

Well the issue seems to be when I right click on an individual part the Height Range option doesn’t show. I have to right click on the print as a whole

Then you can click on these and you can change your settings like I put 0 - 3 mm so it would only iron the cube surface then you pick the iron setting you want.

I’m not sure if this helps, but I have 2 x STLs (both 2mm height), I load the base in as a normal object, then the top as a part. I centre them both and then raise the text to 2mm z-height. Then I choose the base object and turn on ironing (all top layers). Now when I go to slice it shows an imprint of the text in the base which means the ironing happens around it as shown in this screenshot. It’s really frustrating me as I’ve never had this issue with my old Flashforge printer

I tried adding a Height Range and still the same outcome, imprint in the base and ironing around it

Ok is your text a custom logo stl ?

If just words you can use this text tool in the slicer.

Text

If it is a logo text then you will have to get all your parts sized and z adjusted of how you want them then right click and select assemble then do the height iron modifier you must set the height range @ 0 to 2mm for your part sample.

This is two stl done like you want.

I’m using a custom font I’m afraid

Ok then the logo way should work also OcraSilcer has more text settings you can also check it out.
