ultimaker² print qualtiy problems

Recommended Posts

Hello,

though I'm able to produce usable prints, I can't seem to get the print-quality on my ultimaker² right.

Apart from the default settings, I've played with a lot of settings and followed different calibration-guides, but to no avail.

From what I've observed, it seems the string of molten filament that comes out of the nozzle is too thick compared to what comes out of other 0.4 hot-ends I've seen. Reducing the infill doesn't work though, the amount seems right.

As a result, it tends to 'smudge' on edges, making a mess of details. And the infill doesn't come out as lines with a more or less constant diameter, but as thin strings and a lump on the intersection.

I'm sure this machine is capable of more- what's going wrong? I'd upload some pictures, is that possible on this forum, or do i need a external file hoster?

Thank You for your answers, sorry for not being very responsive the last days.

By infill, do you mean 'fill density' or 'infill overlap'?

I usually use a fill density around 30%, as there seems to be a problem bridging bigger gaps when closing the top, as discribed above.

Went down a bit with 'infill overlap', currently at 12%, maybe thats the way to go.

uploaded some pics illustrating the problems discribed above:

Infill thicker on intersections, stringy in between:

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
