I had to give this a try after putting up Christmas decorations. I reprinted this Christmas Tree with my new A1.
Both trees were printed in vase mode, or spiral vase, depending on the slicer. The same roll of filament was used for both. The one on the left printed by an Ender 3 V3 SE and the one on the right by the A1. There is a significant improvement in the A1 print that stands out more live.
But both of these models still have the same obvious defects, the top layers. This is easily seen in the ornaments, and I didnāt get a pic but in the star as well.
Does anyone have any suggestions to improve these little gaps, or maybe hide them? I know this model was never meant to be printed in vase mode but it gives such a cool lighting effect. Thanks in advance.
Yes, it is just standard vase mode. When I use settings for a thicker wall it doesnāt let as much light through.
However I will keep track of these settings for future reference. When I print drink koozies, or collapsible swords and lightsabers, I use the thicker walls settings and I havenāt tried to set those in Bambu Studio yet.
In vase mode, It isnāt possible to print the tops of the ornaments. They are spatially separate from the tree, but at the same height as a layer of the tree. So, there is no way for the extruder to get over there and print them properly without breaking its single extrusion, which is the one hard and fast rule of vase mode.
Does that make sense?
I might just try a ānormal modeā print with single wall, extra thick wall width, no infill print for these. There will be a seam, But the bambu lab printers are really good at unobtrusive seams. Put the seam in the back too to hide it.
I understand about the top layer, thatās why I asked for ideas to hide it. The single wall, no infill idea is brilliant. Iāll give it a try. Thanks
The number of walls is determined by Wall Loops is it not? I havenāt been able to get just one wall when looking at the cross section. Plus itās still getting the same defects as with Spiral Mode even when I increase Top Surfaces.
Itās probably something worth spending a lot of time on. The little holes arenāt really noticeable. Itās just that I know they are there so bugs the ā ā ā ā out of me.
Yes, made sure it was off. I donāt know why I canāt get it to one wall. There is something Iām not understanding in Bambu Studio.
Edit: Think I just figured it out. I am only getting one wall. One on the outside and one on the inside of the model. If it werenāt open at the bottom it likely would only have the outside wall.
Still looks the same, although the little holes look better. But I think itās going to continue to create one wall on each surface, the outside of the model and the inside.
Maybe I just need to print the tops of the little ornaments and glue them in place. Or maybe I just need to quit worrying about it since itās not a big deal. Yeah, probably that second one.
Your 3D model probably is a shell with thickness so is normal to get one wall inside and one outside. If you want only the exterior wall you need the 3d model to be just an exterior surface with caps, like a solid piece of wood for example. Then you will be able to use the one wall method.
The one wall method dough wonāt help with the holes , the top layers wonāt have any support to build onto. There are some domes over there. It might help to use a 0.6mm or 0.8mm nozzle with 0.24mm layer height , it will withstand cantilevered layers better and in the end might result in just very small holes that wonāt bother you that much.
Thanks for all the replies. I may try to make this with a solid bottom to cut out later but itās not really that important. It does need to be open on the bottom to fit on the base I made and for the light to get to the inside of the model. The single wall made by vase mode acts kink of like a lens and creates this nice lighting effect.
I saw a tree the other day that had little ribbons or bows on the ornaments like they were trying to hide where the hook latches on. Got me thinking I could print tiny bows to cover the holes and maybe that would help me get over it. It really is a I know they are there thing as the holes are pretty small.
FYI, the lighting effect looks much better than in the video.
