What you'll need to print:
* An FFF/FDM 3D printer
* Standard nozzle sized at 0.8mm
* Blue painters tape for your print bed. Glue sticks also work on glass print beds
Slicer Setup: Start with a basic PLA profile for your printer. Change the nozzle temperature to 225°C (437°F). Optionally, set the print bed to 40-50°C (104-122°F). Set the flow rate to 135%. Adjust settings from there as needed.
Tip: Put a layer of blue painters tape on the print bed. Filamet™ has great adhesion to the bed.
Nozzle: 0.8mm or larger
Spool Placement: Reducing friction and pull on Filamet™ during printing is important. Try hanging the filament spool just above the printer.

Finished parts can tolerate heat up to around 600°C (1100°F)

Pack:
| PB1 | Place Al2O3 refractory in the crucible |
| PB2: | Bury the print in the Al2O3 |
| PB3: | Tamp down, don't pack or smoosh |
| PB4: | Part should be surrounded by refractory |
| PB5: | Keep at least 15mm between the part and the crucible walls and top of refractory |
| PB6: | Put the crucible in the kiln |
| PB7: | Ramp furnace to 204°C (400°F) |
| PB8: | Hold at 204°C (400°F) for 2 hours* |
| PB9: | Over the course of 5 hours, ramp to 843°C (1550°F) |
| PB10: | Hold at 843°C (1550°F) for 3 hours |
