Begin with a calibrated 3D printer, isopropyl alcohol for resin cleaning, nitrile gloves, and proper ventilation. For FDM printing, you'll need filament spools and a heated bed; for resin, UV curing stations and protective eyewear are mandatory. Basic tools include flush cutters, spatulas, and cleaning brushes for post-processing.
Essential Setup:
Resin printers (SLA/DLP) typically produce higher detail for miniatures due to their finer resolution. FDM printers can work for larger miniatures but struggle with fine details. Consider print volume, resolution capabilities, and maintenance requirements when selecting.
Selection Criteria:
For resin printing, standard gray resin offers excellent detail capture and easy painting. For FDM, PLA is preferred for its ease of use and minimal warping. Specialty filaments like PLA+ provide slightly better layer adhesion for delicate parts.
Material Choices:
Start with clear concept art and consider your printer's limitations. Design miniatures with adequate support contact points and avoid extreme overhangs. Keep delicate parts like weapons and thin appendages sufficiently thick to prevent breakage.
Design Principles:
Use mesh repair tools to fix non-manifold geometry and ensure watertight models. Hollow resin prints to save material and reduce curing time, but include drainage holes. Scale models appropriately for your printer's capabilities.
Optimization Steps:
AI-powered platforms like Tripo can generate 3D models from text descriptions or concept images, significantly accelerating the design phase. Input detailed prompts describing your miniature's appearance, posture, and equipment to generate base models for refinement.
Workflow Integration:
For resin printing, use layer heights between 0.025-0.05mm with longer exposure times for fine details. FDM printing requires slow speeds (30-50mm/s) and reduced layer heights (0.08-0.12mm). Calibrate exposure times and temperatures specifically for miniature printing.
Key Settings:
Place supports on non-visible areas and use lighter support settings for resin printing. For FDM, tree supports often work better for organic shapes. Always support islands and overhangs exceeding 45 degrees.
Support Guidelines:
Lower layer heights dramatically improve detail but increase print time. For display miniatures, use the finest practical layer height. Balance resolution needs against time constraints, using higher resolution only where visible detail matters.
Resolution Balance:
For resin prints, remove supports before curing when the model is still flexible. Soak in isopropyl alcohol and use flush cutters for clean removal. FDM supports typically snap away but may require careful cutting near connection points.
Cleaning Process:
Start with 400-grit sandpaper for major imperfections, progressing to 1000+ grit for finishing. For resin prints, consider using a UV smoothing solution to reduce visible layer lines without manual sanding delicate details.
Smoothing Approach:
Use spray primers specifically formulated for plastics or resins. Apply thin, even coats to preserve detail. Acrylic model paints work best, building up color with multiple thin layers rather than one thick coat.
Painting Steps:
Failed prints often result from improper leveling, inadequate supports, or incorrect exposure settings. Elephant's foot (bulging base layers) requires reducing initial layer exposure or increasing bottom lift height.
Problem Solutions:
Orientation significantly impacts detail quality—position important features away from support contact points. Use anti-aliasing settings in your slicer and consider slow lift speeds for resin printers to reduce suction forces.
Quality Improvements:
Maintain proper scaling by checking dimensions against real-world references. For tabletop gaming, standard scales are 28mm or 32mm heroic scale. Test print key dimensions before committing to full prints.
