Nanovia SiC : Silicon Carbide

This FFF filament loaded at 71 % by mass with fine silicon carbide (SiC) particles allows for the creation, after sintering (thermal without chemical debinding), of 100 % made out of SiC. This ceramic material resists temperatures up to 2200 °C. Printable with most FFF 3D printers without enclosure, the “green” parts can be post treated and tooled with standard equipment.

Advantages

• Create ceramic components with all the advantages of FFF additive fabrication.
• Easy / normal post processing and tooling before sintering.
• Sintering without the need for a chemical debinding step.

Storage

• Store in airtight container with desiccant, out of direct sunlight.
• Dehydrate for 4h at 60°C prior to printing after prolonged exposure to humidity.

Printing

• A reinforced nozzle, suitable for abrasive materials is recommended.

Post treatment

It’s possible to apply normal post treatment techniques on green parts (sanding, polishing, threading, drilling, tooling, etc…), as shown in the following video :

Sintering

Sintering of Nanovia ceramic products is done in two consecutive phases :

• A debinding phase at a relatively low temperature of 400 °C, which evacuates the binding agent.
• A sintering phase directly following the debinding phase at 2050 °C, which fuses the remaining ceramic particles together.
