The Virtual Foundry The Virtual Foundry M300 Tool Steel Filament - 1.75mm (0.5kg)
The Virtual Foundry M300 Tool Steel Filamet is an 85–88% metal-content filament that prints on any open-architecture FFF 3D printer using standard PLA settings. After sintering, prints become fully dense maraging steel at 3.58 g/cc.
- Achieve >3.5 g/cc density in desktop-fabricated steel
- Reduce printing complexity with standard PLA settings
- Enable sintered metal production on any open-architecture printer

The Virtual Foundry M300 Tool Steel Filamet
High-Strength, Fully Sinterable Metal Filament for Open-Architecture 3D Printers
The Virtual Foundry M300 Tool Steel Filamet™ is a fully sinterable metal filament designed for use with any open-architecture FFF 3D printer. Containing 85–88% metal content and available in both 0.5kg and 1kg spools, this filament enables users to create real metal parts straight from their desktop printer. M300 Tool Steel is a maraging steel known for its exceptional strength, toughness, and ductility. Printing is straightforward with standard PLA settings and a 0.6mm hardened steel nozzle. After printing, parts can be sintered to create solid, high-performance metal components.
Key Features of the The Virtual Foundry M300 Tool Steel Filamet:
- Contains 85–88% metal with a density of 3.58g/cc
- Compatible with any open-architecture FFF 3D printer and 3D printing pens
- Prints easily with minimal warping and no special drying required
- Sintering transforms prints into fully metal M300 Tool Steel parts
- Ideal for prototyping and producing high-strength, wear-resistant components
How to Debind and Sinter H13/M300 Tool Steel Filamet
A Step-by-Step Guide to Turning 3D Prints into Fully Metal Parts
Items Needed:
- Kiln / Sintering Furnace with Programmable Controller
- Refractory Container (Crucible)
- Sintering Refractory Ballast: Steel Blend
- Sintering Carbon
Packing Instructions:
-
Add a layer of Steel Blend refractory ballast to the bottom of the crucible.
-
Carefully bury the printed part in the Steel Blend.
-
Tamp down lightly – do not compress or smoosh the fill.
-
Leave approximately 40mm of space at the top of the crucible.
-
Ensure the part is completely surrounded by the Steel Blend.
-
Maintain at least 15mm of spacing between the part and the crucible walls and top surface.
-
Place the packed crucible into the kiln.
Debinding Process:
8. Ramp at 33°C (60°F)/hour to 204°C (400°F).
9. Hold at 204°C (400°F) for 2 hours.
10. Ramp at 17°C (30°F)/hour to 427°C (800°F).
11. Hold at 427°C (800°F) for 6 hours.
12. Ramp at 33°C (60°F)/hour to 538°C (1000°F).
13. Hold at 538°C (1000°F) for 2 hours.
14. Allow the furnace to cool naturally to room temperature.
Sintering Process:
15. Fill the remaining space at the top of the crucible with Sintering Carbon.
16. Ramp at 333°C (600°F)/hour to 1232°C (2250°F).
17. Hold at 1232°C (2250°F) for 4 hours.
Cooling Down:
18. Ramp down at 111°C (200°F)/hour to 593°C (1100°F) (no hold).
19. End program and allow the furnace to cool to room temperature naturally.
