Miniature and Figurine Printing: A Complete Guide

The Detail Challenge

Miniature printing represents one of the most technically demanding applications for FDM. You're pushing the technology to the very edge of what's achievable in terms of resolution, detail retention, and surface quality. A tabletop gaming miniature at a 28mm scale has facial features 1–2mm across, weapon details at a sub-millimetre scale, and texture on armour and fabric that requires print resolution approaching the theoretical limit of standard FDM. Yet with the right setup, settings, and realistic expectations, FDM can produce miniatures that are genuinely impressive and that paint up beautifully with standard miniature painting techniques.

The key is understanding where FDM exceeds what's needed and where it falls short. For bases, terrain, scenery, large creatures, and vehicles, FDM is excellent. For human scale miniatures (25–32 mm) with fine facial features, FDM requires careful optimisation and realistic expectations. Resin printing still has a major advantage at this scale, which is why many serious miniature printers have both technologies.

Hardware Optimisation for Miniatures

A standard 0.4 mm nozzle is at the edge of its capability for miniature scale detail. For best results: use a 0.25 mm nozzle, specific for finer features, sharper edges, and more faithful detail reproduction. A direct drive extruder gives better retraction control, reducing stringing on the delicate features between miniature elements. Good part cooling is critical: miniature overhangs are challenging even for standard prints, and the smaller the feature, the more important cooling is for maintaining definition.

Printer stability matters more for miniatures than for larger prints. Any vibration or resonance appears as an inconsistency in small features that would be negligible on larger geometry. Ensure your printer is on a stable, isolated surface. For Klipper machines, input shaping (see our guide) actually helps miniature quality by reducing the vibration that causes surface inconsistency, even at the relatively slow speeds used for miniature printing.

Optimal Settings for Miniature Printing

Layer height: 0.05–0.10 mm for maximum detail. Wall count: 3–4 walls (thin walls at miniature scale are still structurally adequate with multiple perimeters). Infill: 15–20% gyroid; miniatures rarely need high infill, as they're primarily display objects. Supports: tree supports only; standard supports will damage delicate limbs and weapon details on removal. Enable support interfaces with 0.1mm spacing. Temperature: Find your filament's ideal temperature from a temperature tower. Miniatures require very consistent extrusion, so temperature stability is more important than for larger prints. PLA and PLA+ are the best base materials for miniatures, as their sharp solidification and good surface definition outperform PETG for small scale detail.

Painting FDM Miniatures

FDM miniatures paint beautifully with standard miniature painting techniques after appropriate priming. Apply two light coats of grey rattle-can primer (Citadel, Army Painter, or Rustoleum), allowing full cure between coats. The primer fills the micro layer line texture while highlighting the structural details. Wash, drybrush, and layer shade with any miniature acrylic range; Citadel, Vallejo, Army Painter, or Scale75 all work excellently on primed FDM. The slight surface roughness of FDM can actually enhance wash techniques, shading accumulates naturally in recesses.
