I 3D print a LOT of signs for work and I’m coming across a “quality” issue that I believe is coming from Bambu studio auto generating an “embedded depth” of 0.2mm in layer height with the letters I place ontop of my solid base of my signs.
Example: if I’m making a black sign that says “keep out” in white letters on the flat black base/background. I would model the black base/background at 1mm tall then place the white “keep out” letters ontop of the black base
background and make the white letters also 1mm tall then group the pieces together and send to the sclicer.
In prusa sclicer the model mentioned above would print the entire black base first, then would pause for the colour change, then print the white letters ontop of the black base and it would come out nice and smooth.
In Bambu studio the model mentioned above prints the black base but at the 0.8mm tall layer, it starts to outline certain letters in a completely random order (doesn’t outline all letters just some) and then continues until it gets to the 1mm tall layer then pauses changes to white filament and continues printing the letters.
The “quality” problem I’m having is that when the Bambu studio embeds some of the letters into the black base at 0.8mm layer height (0.2mm into the base layer) it seems to really mess up the smooth layer lines of the base as it’s trying to outline/embed some letters instead of keeping a consistent smooth base until the colour change and letter printing is supposed to begin at layer height 1mm
I don’t know how to turn off the embedding 0.2mm into the layer below when printing my signs and to be honest the quick and simple way prusa sclicer scliced my files produced a much higher quality print.
I don’t have the answer, but I have the same problem. I create my text models in Blender and set the text exactly on top of the background layer, but Bambu Studio still partially embeds some of the letters in the background layer before switching colors. Not only does this mess up the neatness of the background layer, but it adds to the print time.
Edit: sorry for the misinterpretation. I don’t print signs, but I spent a significant time working with the slicer text option to find all combinations.
If understood correctly, you want to print a 1 mm thickness all black colour filament with the letters debossed. In the next layer, white text is printed and the rest of the layer remains black. Is this correct?
I think I’ve experienced the same thing with prusaslicer, Where it will never do a complete top fill if there are letters above even if you use 100% infill. You know how the annoying paper clip Joe pops up and says “It looks like you’re making a logo, shall I insert a color change?”, well I feel they needed to add " and use as many different fill types as I can to make your base look like ****?"
I now do all my sign face down make the letters 0.6mm thick(3 layers) which results in about 2 or 3 color changes at the beginning and the signs look much better.
I haven’t tested this extensively, but it worked on one of my projects. Try changing the “Only one wall on top surfaces” setting to “Topmost surface only” instead of “All top surfaces.”
