Morning everyone!
Nearly all settings stock; calibrations and such untouched (honestly, I’m newer to the scene and don’t know how to do those yet because my P1S-es have run so well out of the box), primary edits are regarding top/bottom layer count and gyroid infill at 15%. That might even be all of the modifications, but there is certainly nothing drastic like flow rate or temp edits. Because of the shape, I will mention that no, this was not in vase mode. The nozzle is .4mm, I’m not 100% sure if it is the stock nozzle or hardened steel one. I bought some nozzles to try out different things and don’t recall what material made it back on the machine after I was happy with .4 as a general purpose option.
Material is 3DGenius rainbow filament. I’m making a toy for my children that involves an Arduino as a project for an engineering class and this was available in a small spool for just a few dollars. I don’t have a dryer, but it does live in my sealed tote currently reading 32% humidity with desiccant. On an unrelated note, the point wasn’t to try something described as silk PLA but I do like the finish, are more known brands of PLA typically better at achieving a given adjective such as silky or the wooden styles that I’ve seen touted? If I get some Bambu, Sunlu, or Polymaker silk will I reasonably be able to expect an even silkier finish?
I’ll expand more in the next paragraph, but I have found ever so little when googling ‘seam artifacts P1S’ and such, and the most useful thing was a Reddit thread that adds to my confidence but is 2 years old and didn’t really offer any enlightening information.
Now that the preliminary stuff is over, does anyone know what causes this problem? I’d be willing to bet that it is seam related but not 100% sure, as it is on the seam line and worst on said seam, even though it exists on the other corners of this rounded square profile. The seam is atrocious but for several reasons I’m going to roll with it. Of the corners that are on either side of the seam the issue persists, but maybe at 40% intensity and the opposite corner as well but maybe at 15% intensity, using the seam as a 100% reference.
I printed 4 of these at varying height where the primary difference is they’re scaled in one direction; this is the ‘original’ model, with the other three being .5x, 1.5x, and 2x taller, before adding finishing touches such as a uniform thickness baseplate.
Again, these are going to end up being a part of a toy for my toddlers so I didn’t pay attention to the other three until I saw this one; one is good enough along the seam that I’d send it to a customer, the other two are much less egregious but still have some of this issue.
When modeling, I opted for 1/16" wall thickness if memory serves.
I’ve printed things before and since with this printer without this problem, but not with this filament. If not related to the seam and not related to wet filament then I’m not sure where the problem would be (again, I’m newish to this and a vast majority of my experience regarding education has been on the modeling side of things; I went with Bambu because I wanted to 3D print things, not learn how to be an extrusion CNC tech, though I am both willing and capable; this issue is just so severe and seemed to come out of left field I figured it was proper to investigate a little).
I’ve not finished assembling so if needed I can get more pictures. At some point, probably in the next 72 hours, I’ll be turning them into LED towers and once they’re glued shut/wires run and soldered, I doubt I’ll be able to justify tearing them apart.
To those in America, happy Thanksgiving and thanks in advance to anyone who has information!
