Best filament for D&D miniatures: detail at tabletop scale

Short answer

For D&D miniatures, PLA is the right filament, printed through a small nozzle at low layer heights. At 28mm scale the battle is all about detail, and PLA holds crisp facial features, weapons, and chainmail where flexible or stringy filaments blur them. The trick is the nozzle and layer height, not the material brand.

What a gaming mini needs

A tabletop mini is small, detailed, and handled often. That points to a stiff filament that holds fine features and prints cleanly at tiny scales. PLA does this best. It does not string across a raised sword arm, it renders a 0.2 millimeter nozzle line sharply, and it takes primer and paint without fuss. The Prusament PLA datasheet confirms the low print temperature and stability that keep small features sharp.

PETG is the only real alternative, and it earns a place for monsters and large figures that get passed around the table and dropped. It is tougher than PLA, so a PETG troll keeps its arm after a fall. The cost is mild stringing and softer detail, which is why most painters keep PLA for the heroes they want to look sharp.

Printing a batch

PLA’s speed and reliability make it ideal for printing a whole party or monster horde in one go. Print slow for the outer walls to keep detail, and use a brim only for top-heavy poses that tip. For display and painting focus rather than gaming, the miniatures page covers paint adhesion and finish, and the tabletop page covers the broader gaming setup. The PLA hub has settings, and the filament overview gives the wider field.
