Working with D2 Tool Steel

D2 Tool Steel can be heat treated to increase hardness and durability. Markforged recommends heat treating D2 Tool Steel to optimize material properties, though it can be used as-sintered. Heat D2 Tool Steel part in a standard (non-vacuum) furnace to 1000°C (1830°F) . Hold part at temperature for 30-45 minutes. Air quench part to below 65°C (150 °F). Temper D2 Tool Steel Tool Steel part in a standard furnace. For each temper, heat part to 200°C (392°F) and temper for 30 minutes. If double tempering, let part cool to room temperature between tempers.

Compatible with our Metal X system.
