Metallic Bronze PLA for FDM printers

Ziro 3D PLA Pro filament comes in a 1.75mm metallic bronze colour on a 1kg spool. It suits hobbyists and makers who want consistent extrusion on Creality, Anycubic, Bambu and other FDM machines. The material is biodegradable PLA that prints without a heated bed and releases no odour during use.

Low-warp printing at 190-220°C

The filament prints between 190 and 220°C with an optional bed temperature of 50-60°C. Manufacturing tolerance is held to ±0.03mm and the spool is 100% tangle-free, giving smooth flow and strong layer adhesion. Vacuum-sealed packaging keeps the roll dry until it reaches the printer.

Upgrade from inconsistent budget filament

The tight ±0.03mm tolerance replaces loose-spec rolls that cause varying line width and failed prints. The jump is worth it when dimensional accuracy matters for functional parts or when reliable bed adhesion saves reprint time. Buyers needing more than 1kg per colour or exotic composite materials should look elsewhere.

Questions about this item

How do I load the 1.75mm filament into my printer and what step causes most jams?

Heat the nozzle to 190-220°C, then feed the 330m spool through the guide tube; the step people miss is letting the vacuum-sealed roll sit unsealed overnight, which lets moisture swell the filament and clog the hotend.

What part of this spool will need replacing first and when?

The 1kg PLA filament itself is the consumable; after roughly 330m of extrusion you simply buy another spool — no nozzles, gears or belts are included to wear out.

At what print speed does layer adhesion start to suffer on long prints?

Stay at or below the suggested 90mm/s ceiling; pushing past that on extended jobs reduces the 0.03mm tolerance advantage and weakens inter-layer bonding.
