Armour is the largest, lightest thing most people ever print, and every seam is an hour of filling and sanding. A 300 mm class printer (Creality K1 Max) prints most plates and helmets whole; 400 mm (Ender-5 Max, Kobra 3 Max) prints chest plates and shields in one piece. A 0.6 mm nozzle, two walls and low infill make a plate light and fast; lightweight foaming PLA halves the weight again. Reliability over 20-hour prints matters more than speed.

Settings for plates
- 0.6 mm nozzle, 0.3 mm layers, 2 walls, 5 to 8 percent infill, 3 top and bottom layers.
- Orient the plate so overhangs face down onto supports you will sand anyway; the outer face up.
- Lightweight foaming PLA at 220 to 250 °C for helmets and shoulders; halves the weight.
- Split on natural edges with pins; CA glue, then filler primer.
Filament
PLA+ for most plates, PETG for straps and clips, ASA for anything in the sun. See filament for cosplay. Twenty-hour prints fail on wet filament; dry it.
Long-print reliability
A camera and filament runout sensor save more armour than speed does. The K1 Max lidar and the Bambu spaghetti detection are worth having; see detached prints. See printers for cosplay for props and large format for the full size ladder.
The units in the box
The listings are the K1 Max, the Ender-5 Max and the Kobra 3 Max Combo.
FAQ
Do I need an enclosure? No; PLA armour prints best on an open frame or with the door open.
How much filament for a full suit? Several kilograms; buy PLA in bulk.
