Protopasta Iron Composite PLA, 1,75 mm / 500 g

Protopasta's easy-to-print Iron-filled Composite PLA is a ferromagnetic, iron-filled PLA material that behaves like pure iron and has a stable, matt cast metal finish when printed.

Tip: Compared to a standard PLA, the density of this material is 1.5 times higher; the filament also shows higher thermal conductivity than other plastics.

Danger! When processing abrasive materials, individual components can wear out more quickly. Therefore, it is recommended to regularly maintain the hardware and replace the nozzles. For prolonged use, wear-resistant nozzles are recommended.

⇒ For best printing results, Protopasta recommends using a 0.6mm nozzle and a printing temperature of 210-230°C. Nevertheless, the composite filaments can also be easily printed with a 0.4 mm nozzle. A heated bed is not required.

Common finishing techniques for metal composite filaments:

► Heat treatment so that the 3D prints survive high temperatures, the sun or warm polishing pads,

► Processing with a wire brush for later oxidation or a bright, satin finish,

► Stone grinding with steel grit for a darker but smooth, shiny look,

► Partial painting to fill recesses with a contrasting colour,

► Polishing with a rotary tool, cotton buff and polishing paste for a bright, reflective surface,

► Polishing with paper for a clean, smooth and shiny surface with less darkening.

► Oxidation of exposed metal naturally or accelerated with a 50/50 vinegar/hydrogen peroxide mixture saturated with salt. Storing the printed part in a sealed plastic bag will retain moisture; Heat further accelerates the reaction.

Tip: Once you have achieved the desired finish, solidify it with a coat of clear varnish or a brush-applied water-based, food-safe and dishwasher-safe varnish.
