Introducing Magnetic Iron Filled PLA. The strength of Protopasta Magnetic Iron PLA is similar, and likely somewhat less, than the strength of standard PLA. The iron in the filament is too finely ground to provide an increase in overall strength. The iron is too small and separated by the PLA to offer any noticeable amount of conductivity.
We call our material “Magnetic Iron PLA” to communicate that this material allows users to include the added benefits of magnetism when designing and printing 3D objects.

Material Data
Base resin: HTPLA - Heat Treatable PLA
Particle size: less than 250 microns (0.25mm)
Odor: low or no
Density: 1.8 g/cm3 (1800 kg/m3)
Length (500g): 97m (1.75mm) and 36m (2.85mm)
Heat treating: 110C (225F) for 10 min or as required for the desired result
Total loss of stiffness (before heat treat): 50-60C (Tg)
Total loss of stiffness (after heat treat): 150-175C (melting)
Dimension change (before heat treat): 0% X/Y/Z
Dimension change (after heat treat): 1.5% shrink X/Y and 1% growth Z typical but please calculate and confirm for your specific print and process
Printer Settings
Speed: 10-20 mm/s 1st layer, 20-80 mm/s rest of part
Nozzle Set-point: 185-215C (hottest on 1st layer for best adhesion)
