Meldform: meld for printing

A small Blender tool with one job: meld a collection of parts into one watertight mesh with smooth blends, ready to 3D print, or hollow it into a shell for resin printing.

Blender add-ons
Three versions of a toy figure: the separate primitive parts, the parts melded into one smooth clay mesh, and the melded mesh hollowed and cut open to show the shell

What it solves

The gap

Models built from many overlapping parts are not printable as they are: they need one closed surface, smooth joins, and often a hollow shell to save resin.

What it is

One click adds a modifier that melds the parts into a single watertight mesh with fillet blends, with an optional hollow shell and a volume readout.

How you use it

Select the parts, select the main mesh, click once, then set Blend and Wall.

A micro-tool for one job, getting parts into one printable mesh, not a full SDF modelling system.

Who it is for

Use it when

  • Turning kitbashed or primitive-built figures into one printable mesh.
  • Hollowing models for resin printing to save material.
  • Making smooth, blob-like base meshes from simple shapes.

Built for

  • Blender users who 3D print their models.
  • Artists who block out shapes from primitives and want one clean surface.

What it does

Meld

The object and every mesh in the Parts collection become one closed surface. Parts that overlap join; parts that do not stay separate pieces of the same mesh.

Blend and smooth

Blend fills the seams where parts meet with a smooth fillet; Smooth softens the whole surface; Grow thickens or thins everything.

Hollow for resin

Hollow keeps only a shell of the wall thickness you set. Add your own drain holes before printing.

Measure and stay safe

Measure shows the volume and whether the mesh is closed. The voxel size is capped from the model size, so a tiny value cannot freeze Blender.

Questions

It keeps the object's material. UVs are not kept, because the result is a new surface built from a grid.

Closed meshes. An open mesh, such as a single plane, gives an empty or odd result.

Blender 5.2; it is tested on 5.2.1 and 5.2.2 on Linux. Blender 4.2 and 4.5 LTS, Windows and macOS were not tested.

Built with the help of an AI coding assistant; checked by PN Scripts with automated tests in Blender. Images are renders of procedural Blender scenes; no AI-generated imagery.
