UM3 PLA layer holes with PVA support

Recommended Posts


I printed this model with orange PLA and with PVA support, but as you can see, i get these layer holes in the lines and a rought surface. This is normally not present while just printing PLA, and I guess it could be the support interface PVA that is overlapping into the model.

What setting should I use to make more distance between the PVA and the PLA. Or is it another issue?

    • "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.
