shifted layers?

Recommended Posts

Posted · shifted layers?

Hello everyone,

I bought a um2 a few days ago and have successfully printed some models, but I am having troubles with this one.

For my first try, I printed it horizontally but the bottom was ugly.

So I tried to cut it and print two half vertically, and I get what you can see here:

Why is this happening? Should I thicken the shape, change the settings of the print?

It's hard to see how big the print is but I'm guessing it's quite small? If so, it's most likely a cooling issue. The plastic isn't given enough time to cool so it's a bit like chewing gum and can move around a bit as it gets pushed around by the nozzle.

Try printing a couple of copies at the same time and see if that helps.

Thanks for the help, I thought about cooling too.

I need to print small pieces, this one have a diameter of 10cm, but the thickness is 1 - 2 mm only. I have tried to play with the minimum time per layer, without success for the smallest parts.

I am going to try with a couple of copies, but maybe I should look for better settings too?

Should I try with a smallest nozzle (I have only used a 0.4 for now)? How to adapt settings for small prints?

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
