Trouble with infill pattern

Recommended Posts

Hello everyone,


I hope that all is well. Recently I have been facing infill problems with my 3D prints on the Ultimaker 2+. I'm not sure why the printer is unable to finish the infill patterns. If you look at the pictures attached to this, you'll see that some of the grind lines are not complete. From the right to left, I have changed the speeds for each print to improve the quality but the infill problem keeps showing up, I'm unable to figure out why. Any help/suggestions will be appreciated.

Which PLA are you using, because 230° C for PLA seems quite high.

Your print looks overall not really good, so I guess you have probably a problem with your Extrusion (Feeder, Bowden Tube, Teflon coupler, clogged nozzle) and/or your material brand is not the best (printing with cheap PLA can be terrible).

    • "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.
