Adaptive Infill

One of the new features of Voxelizer is the adaptive infill.

You know when you have a model which has few horizontal surfaces and only because of that you have to use a dense infill? Or when you model is big and you want it to be solid but to have all that infill in its inside seems like a waste? These are the problems that this new type to infill is addressing.

Let’s take for example the model of these mountains which we often send to resellers and clients:

It is usually printed with a layer height of 0.16 mm and a light durability preset, with a 30% of infill. With these parameters, the total amount of filament used is 35.11m and the total printing time is 16h 01min. Anyway, only the flat parts of the model require this big amount of infill. Time to try the new adaptive one.

Between the durability presets, let’s select adaptive, giving it a value of 50% and click NEXT.

The printing time has dropped to 8h 45min and the filament used to 17.73m. A saving of time and filament of 50%!

If you look at the generated gcode you will notice that the adaptive infill will become denser when approaching the surface of the model, while remaining sparse towards its inside. With this approach we address both the problems mentioned in the beginning: having the right amount of infill only where it is needed while ensuring solidity to the model.

You will get the best results with an infill value of 50%, however you can experiment with higher or lower settings.

Likewise, if you want to be sure that the distribution of the infill density occurs precisely, you can increase the Width/height ratio parameter under the Durability settings at the cost of a higher time of computation.

Instead, if you want to further increase the solidity of the model, you can activate the Line crossing option at the cost of a higher printing time and filament used. The horizontal and vertical infill lines will cross at each layer instead of alternating.
