3D Print Warhammer Minis — Resin Settings & Scale | 3D-P.eu

Tabletop wargaming miniatures—such as 28mm to 32mm heroic-scale Warhammer 40k and Age of Sigmar figures—feature intricate details: facial expressions, power armor panel lines, purity seals, and delicate weapons. While FDM printers struggle with stair-stepping on tiny curves, modern desktop resin printers can reproduce sub-micron details that rival or exceed commercial plastic kits. Achieving showroom results requires mastering orientation angles, custom light support placement, and proper post-cure rinsing.

Optimal Resin Slicing Settings for 28mm/32mm Miniatures

The 4 Pillars of Flawless Miniature Resin Printing

1. The 80/20 Durable Resin Blend Formula

Standard hobby photopolymer resin is notoriously brittle; dropping a miniature onto a tiled floor or gaming table often snaps weapons or limbs. The gold-standard community solution is mixing 80% high-detail ABS-like resin with 20% high-flex resin (such as Siraya Tech Tenacious). This creates resilient models that retain crisp facial micro-features while absorbing bending and impact shocks without breaking.

2. The 35°–45° Tilted Orientation Protocol

Never print a miniature standing flat parallel to the build plate. Orienting the model tilted backwards at 35° to 45° reduces the cross-sectional surface area of each individual layer, dramatically lowering FEP suction forces and directing all support contact points to the back and underside of the miniature where scars are easily hidden.

3. Graduated Support Strategy (Heavy, Medium, Light)

Use a hierarchical support architecture in your slicer (Lychee Slicer or Chitubox Pro):

• Heavy Anchors (0.80mm tips): Place 2 to 4 heavy supports at the lowest structural points (heels, base contact points) to anchor the model firmly against the build plate.
• Medium Supports (0.45mm tips): Support primary limbs, weapons, torso overhangs, and heavy armor segments.
• Light Micro-Supports (0.20mm–0.25mm tips): Support fingers, gun barrels, cloth capes, and sharp feather details to prevent delamination without leaving surface pits.

4. Warm Water Bath Support Removal Before Final Curing

Always remove supports after solvent washing but BEFORE final UV curing. Submerging the washed, uncured miniature into warm tap water (50°C) for 30 seconds softens the support tips. Supports will peel away effortlessly like velcro without tearing divots out of the model’s delicate surface.
