3d printer slicer settings for top layers

Try eliminating cooling and see if it helps.If using Bambu filament, ensure you are selecting Bambu filament profile.In any case, it would be best to stop your current 3D printing project to make the adjustments and do a few test. It’s either your 3D printer is in dire need of maintenance, or your slicer settings need a major overhaul. This completely fixed my other issues being the top surface was going a bit too slow causing the part cooling to cause waves in the plastic. Skipped layers in 3D printing are rare, but they are symptomatic of a serious problem in your hardware or slicer settings. I then decided to bump the top surface speed to the same as my internal/sparse infill speed (270 mm/s). This helped a bit but I still had some top layer issues. This side fan is mostly unnecessary for PLA (there are some cases where it might be helpful, but largely no). (3) The top surface also has the side-fan set to 70% and part cooling at 100% BUT the speed is set to 200 mm/s.Īfter some tweaking, I deduced that this top-layer problem must be related to COOLING and SPEED differences on the different layers. Perimeters, Top Solid Layers, Bottom Solid Layers These settings determines the thickness of the walls of your part. (2) The middle layers (infill and wall layers) have the side-fan set to 70% and part cooling set to 100% and speeds between 250-300mm/s.

The bottom-most layer has 50mm/s speed (very slow). There’s no side-fan (AUX fan) or part cooling (from extruder). (1) The bottom-most layer has NO cooling. The thinner each layer is, the smoother the print surface looks. The line texture on the printout surface is just the result of layer-after-layer printing. This parameter directly affects the smoothness of outer surface of the print. Layer height means the thickness of each layer. I deduced that it must be related to some difference in settings from the top layers vs the bottom layers. 3D model is sliced and printed layer by layer. My hypothesis was that if all my other layers look good, how could it be that only the top layer(s) start messing up? 1.2K 36K views 1 year ago Cura Advanced Topics 3d Printer Slicers should be a valuable tool in your design process. With a lot of painstaking tests, I found out why it happens only on the top layers whereas all the other layers look good.
