PLA/PHA filament and fine steel powder.

For experienced user.

SteelFill is quite abrasive to brass nozzles. It can effect the print quality after printing 1.5 kg. It’s recommended for this grade of metal filled filament to print with abrasive resistant nozzles, for instance the E3D hardened steel nozzle, the JET RSS50 and performance 3-d Hercules nozzles.


  • Shines like steel when polished
  • 3 times heavier than standard PLA
  • Heated bed not required

SteelFill can be printed on a cold platform simply using blue painters tape. If your machine does include a heated buildplate then we recommend setting it to about 50 °C for nice flat bottom layers. The suggested 3D print speed is around 40 - 80 mm/s. When the 3D printer is finished printing the part let the platform cool back down to room temperature.

For your first prints it is recommend using layer heights of 0.2mm up to 0.27mm when using 0.4mm nozzles. When choosing smaller layer heights, remember to adjust either printspeed (more) or reduce temperature slightly to accommodate for the lower volume of material being extruded.

Use cooling only if the model needs it. So if the model has lots of fine details, overhangs and pointy bits, cooling will be needed to keep these nice and crisp. Less cooling generally will give better layer adhesion. Starting with 50% cooling is good to feel how the material behaves in your machine.

Keep retraction settings at a minimum, most steelFill prints will need post processing anyway.

Due to all the different types of hot-end it's extremely difficult to give a temperature advice. Please consider these tips, provided by the manufacturer, as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
