Dear experts and 3D printer users;

I am a beginner in 3D printing field. I read couple of answers in forums and i cannot find exact answer to my problem.

Printing quality dropped when i try to write vertical axis (i mean, columns). There is no problem in horizontal axis.

My column width must be 0.5 mm, and printer nozzle diameter is 0.4 mm. I think I should write 0.5 mm column with 0.4 mm nozzle with ease.

I added messy structure to this post and you can find writing details below. Printed Structure What do you think? What is your suggestion to overcome this problem?

Printer:Ultimaker 3, Slicer:Cura,

Printing Details; Nozzle diameter:0.4 mm, Profile:Fine 0.1 mm, Layer height:0.1 mm, Wall thickness:1 mm, Top bottom thickness:1 mm, Infill density: 100 %, Gradual infill steps:0, Printing Temp:240 C, Build plate Temp:65 C, Diameter: 2.85 mm, Dimensions of the material:10X10X5 mm

You cannot hope to print 0.5mm columns with a 0.4mm print head successfully using an FDM printer. Basically, you are asking the printer to lay down tiny blobs of filament, one of top of another. You have two options:

  1. Use a finer nozzle (e.g. 0.1mm). However, such nozzles are reported as being very difficult to use.

  2. Switch to a different printing technology (e.g. SLA). Resin and powder-based printers have much finer resolutions, and will have no difficulty printing the model that you describe.
