Description

Proto-Pasta Composite Iron PLA is a specialised 3D printing filament that responds to magnets like iron or steel, allowing printed parts to attract magnetic objects without being magnetic themselves. The material features a matte grey finish resembling cast metal and can be treated with water to create an aged, rusted appearance for authentic industrial aesthetics. With a density approximately 50 percent higher than standard PLA, printed objects feel substantially heavier and less plastic-like, providing a premium tactile experience. Processing is comparable to standard PLA, requiring no heated bed, though the filament is more brittle than conventional PLA and demands careful handling to prevent breakage. Proto-Pasta recommends printing at 190-230 degrees Celsius using a 4mm or larger nozzle for optimal results. Process consistency may be reduced on smaller 0.4mm nozzles or Bowden-type machines. Designed and manufactured in the USA, this filament combines ease of processing with distinctive magnetic properties ideal for artistic, functional, and industrial-looking 3D prints.

Key Features

Magnets stick to printed parts made with Proto-Pasta Composite Iron PLA, creating functional and interactive objects without the material being magnetic itself.

Matte grey finish with cast metal appearance provides authentic industrial aesthetics that resemble genuine iron or steel components.

Surface can be treated with water to develop a rusted, distressed look for aged or weathered decorative effects.

Density is approximately 50 percent higher than standard PLA, giving printed objects noticeably more weight and a premium feel.

Process requirements are comparable to standard PLA with no heated bed necessary, simplifying setup and printing workflow.

Print at 190-230 degrees Celsius using a 4mm or larger nozzle for best results; smaller nozzles and Bowden machines may experience reduced consistency.

More brittle than standard PLA filament, requiring extra care during handling and storage to prevent cracking or breakage.
