You can add them to your scene from the Add menu ( Shift + A + Metaballs).

Metaballs are interesting and wacky things. Metaball objects: Although I said that Blender is not a parametric modeler, Blender actually does have some parametric objects-specifically, I'm referring to Blender's metaball objects.

The following two techniques are a bit idiosyncratic and go back to the less precise, sculptural way of modeling, but they can be pretty handy for roughing out a base mesh that you intend on refining with sculpt tools:ġ. It's possible to build mesh models in an additive or subtractive way without using Blender's Boolean modifier or either of the add-ons mentioned in Part 2 of this series. Now let's look at advanced tips, including metaball objects, joining objects with the fluid simulator, prepping for print, and the 3D Printing Toolbox add-on. In Part 2 I examined the process for making those models. In Part 1 of my series on getting started with 3D printing in Blender, I covered basic preliminary steps for getting your Blender environment set up for creating your own 3D models, ready to be 3D printed.
