Dear reader,

The shape I made with 3 atom arrays is for a 3D print. I tried several times to convert it to a single shape (watertight) to export for a stl file.
Can you help me with this shape and can you tell me how to get an array into a shape without the lines and sphere adges on the inside.
(tried it with editable, boole combine the shapes and connect and delete)

Thanks in advance!

Kind Regards,

Hi Michiel,

Edit: with the new release the Volume modeling should do the trick /edit.

Here is an alternative, see file below:

The Pyramids needed to be merged, and the floor of two to be deleted, points optimized.
Then one can harvest with the Mesh>Commands> Edge to Spline the “contour”.
With a interpolation of 64 linear, Current State To Object, and set to a scale of 100
The Metaball was set to 50% 50cm to start with.
A very dense mesh was the result.
The application “Instant Mesh” was then used to get a low density mesh, and that was scaled down then.

A little variation of the workflow which captured a “Primitive to Scaffold” procedure:

One could place in the thicker parts some little objects with a Metaball Tag and a negative value to get smaller “corners.

This shape needs a powder or fluid based printing, or you have to set a scaffold around it.

If you model it, think about that you have to model only an 1/8th of it. Anything else is repetition.

All the best

P.S:

Here is a modeled version. I left the main steps in, start to end/top to bottom.

From my experience with several print houses, this resolution should work. The last company that I have used offered also a polishing of the powder based result.

My best wishes

P.S.: a much simpler way than in the tutorial below was used here, but often the idea is the same, create on edges the information one needs
