A Checklist for Image to 3D for 3D Printed Miniatures
A general print isn't the same job as a 32mm miniature that has to read on a tabletop. This page is the checklist for image to 3d for 3d printed miniatures: what a figure needs before it counts as done, and where a generated mesh usually still needs a hand.
The checklist
What a Tabletop Miniature Actually Needs
A printed miniature is judged by rules a general print is not: it has to hold a pose, sit flat on a base, and read from across a table.
| What it needs | Why it matters |
|---|---|
| Correct scale in mm | 28mm and 32mm heroic scale are the two common targets, set explicitly on export |
| A pose that reads small | Wide, open poses survive shrinking better than tight, overlapping ones |
| No unresolved undercuts | Deep undercuts are hard for a resin or FDM printer to resolve cleanly |
| A flat basing surface | Most generated 3D meshes have no base, you add one before printing |
| Detail that survives the shrink | Fine detail on a full-size render can vanish once printed at miniature scale |
| A watertight mesh | Needed before any slicer will accept the file |
Step by step
Working Through the Checklist, Step by Step
Working through that checklist in order, from the reference image to printed miniatures your printer can actually run.
Pick a Reference Image That Shows the Pose
A character concept or a clean image with the whole figure visible works better than a cropped image, the reconstruction pass has to guess less about the pose that way.
Set the Scale on Export
The generated 3D mesh has no built-in scale, so decide on 28mm or 32mm before exporting and size it in Blender or your slicer rather than guessing by eye.
Check for Undercuts and Thin Parts
Rotate the 3D mesh and look under capes, arms and weapons for geometry a printer cannot reach, thin swords and banners are the parts most likely to need a small manual fix.
Add a Base
Miniatures need a flat basing disc that this tool does not generate on its own, add one in Blender before export so the figure actually stands on a tabletop base.
Export and Slice
Once the 3D mesh is watertight, scaled and based, export STL or 3MF and slice it the same way you would any other printed miniature file, with supports where the pose needs them.
Quality bar
The Quality Bar Before You Print a Whole Army
Before printing a whole army of miniatures off one mesh, it is worth checking the single figure against a short quality bar.
Give the 3D model a full rotation and look at the side and back the image never showed, a single reference image means that geometry is inferred rather than observed, so it deserves a skeptical look rather than blind trust. Objects at this rough scale, a rune-engraved anvil prop or a horned helmet, show the same level of surface detail you should expect on a character model: enough to read clearly, not enough to assume every strap and buckle survived the reconstruction pass without a check.
If the detail looks soft anywhere that matters for the pose, a weapon, a face, an insignia, that is worth a manual touch-up in Blender before committing to a print, the same care any printed miniatures deserve, rather than discovering it after the resin has cured.
The rework
The Rework You Will Do Most Often
The rework that comes up most often is not really about the 3D mesh quality, it is about the things a print-from-image tool has no way to know: it does not know you want a base, so you add one; it does not know your printer's minimum feature size, so a thin sword or feather gets thickened by hand; and it cannot see the side of the figure your image left out, so that side occasionally needs a small manual correction after a first look.
None of that is a sign the 3D mesh failed, it is the same finishing pass any 3D print from an image needs, especially for printed miniatures, just applied at a scale where a small mistake is easier to notice once it is printed than before.
Questions
Frequently Asked Questions
Yes, generate the 3D mesh from a single reference image, then work through the scale, undercut and basing checklist above before it goes anywhere near a slicer.
No, the generated mesh has no base disc. Add a flat basing surface yourself in Blender before export, that step is manual for every printed miniature you generate.
Either works, it depends on the rest of your collection. Set the target height explicitly when you export rather than relying on the mesh's default size, which is arbitrary.
Not always without a check. Rotate the 3D mesh first and thicken anything that looks too thin for your printer's minimum feature size before it goes on the build plate.
Yes, a single reference image or concept image of the character works as the input, just expect to check the pose and undercuts the same way as any other printed miniature.
