Scratchy layers and solid fill-ins for top layers. Does any one have any tips on solving this, please?

Recommended Posts

The printer starts printing the first layer pretty smoothly but as it moves to the second layer it already starts to come out scratchy and the solid layers are totally messed up. As you can see in the picture the first layer looks completely normal but the second one is very scratchy. Has any one had this problem? Any idea how I can fix this? Thank you in advance.

What printer are you using and what material?

The first layer is printed typically slower and at a higher layer height them the preceding layers. So you may need to alter your speed or adjust the temp.

I'm using a ultimaker 2 and ultimaker pla.

I've tried slowing it down a bit but nothing changed, haven't tried adjusting the temp yet. I'm using the preconfigured normal quality printing from cura, How should I alter the temp and the speed?

How many print hours has your UM2 done? You may find the PTFE coupler needs changing. You can replace this with the TFM or TFT coupler that is used in the UM2+ which lasts much longer. Even replacing the spring with the alloy spacer or printed spacer will help.

You can alter the temp on the printer as its running in the tune menu. You need to wait a while after adjusting to allow everything to stabilise.

    • "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.
