Idea. Progressive Infill

Recommended Posts

Been thinking about this a few weeks and I think It could be a nice idea for a plugin but I don't have programming skills.

The idea it's that the infill progresses on a range that the user sets. Let say 10-26. And then you choose how many layers or height to do the progression.

This might allow for big objects, like ironman heltmets and stuff that takes too much time to print to have a semi hollow interior but as soon the top layers get close (or bottom banishes) the infill starts to get tighter so it's easier to make a good locking layers and save a lot of time from 10-15cm of hollow low-infill inside.

Increasing infill towards the top means that some of the infill towards at least one side won't really be resting on top of anything while it's printing. This requires a lot of bridging. It won't be able to transport a lot of force, so it won't make the model much stronger. That is, if the infill pattern is simply resized as it is done now. It requires a bit of creative thinking to get this idea worked out proper, I think.

Perhaps something like gradually splitting lines in two as it goes up? Like if you'd see a side-view you'd see a tree structure, but then with the sides of triangles rather than single lines?

Plug-ins for the back-end of Cura (CuraEngine) are planned for the future, by the way, but will take a long time to implement properly.

    • "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.
