Poor surface quality on parts with retarction

Recommended Posts

http://umforum.ultimaker.com/index.php?/gallery/album/1009-bad-surface-quality/

Ive uploaded some pictures in this album of my attempt to print emmets folding lamp shade thing.

And the print quality is horrible. Lots of odd layers and blobs.

I need help and advice to what im doing wrong, or if its something worn down on the printer.

You have two completely different problems. The lower area has problems caused by overhangs I think. The upper area has basically slicing issues. What version of Cura are you using? There was a bug introduced recently and then fixed in the latest version that can cause the problems on the upper areas of the shade.

You might be able to improve the upper area by having a shell of .8 (2 passes).

The lower area will be improved if you slow it down quite a bit and it's critical that the fan is on 100% to get good quality surfaces. Try 20-35mm/sec just to see what happens. Let it print for 24 hours if that's what it needs.

A third issue: there are some layers that look thicker - as though the Z didn't move enough. I would grease the Z screw and move the bed up and down to make sure it isn't getting stuck on some layer moves. Also consider .2mm layer height as the thinner you go the more likely you get these long horizontal bands.

Yes, just pushed that to address some UM2 firmware issue that I didn't fix properly. (Or, "I should have listened to Simon")

 

I guess it's the same as the hex file that illuminarti linked in an other subject?

The new feature with first layer width (there's a typo in the label with instead of width) is it possible to specify more than 100% ?

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
