Sintering Crucible - Refractory Cement

Filamet™ can be debound and sintered in a kiln, making 100% metal, ceramic, or glass parts. A crucible is required to hold the part for this process.

How To Use:
⚠️ Before debinding or sintering for the first time, it is recommended to fire the empty crucible once. Ramp to 649°C (1200°F) over 4 hours and hold for 1 hour. Then your crucible is ready for use. More details here. ⚠️
Bury prints in an appropriate refractory then place the crucible in the kiln and start the program. Use the lid (or other covering) for the sintering cycle to help preserve Sintering Carbon. Full instructions can be found here.
