Once selected, these materials undergo processing methods such as tape casting, injection molding, and laser machining to form the basic structure.

Tape Casting

Tape casting is a prevalent technique for producing thin ceramic sheets.
It involves spreading a ceramic slurry evenly over a flat substrate to form a thin, uniform layer.
Once dried, these sheets can be cut and shaped into various micro-sized components.

Injection Molding

Injection molding involves injecting a mixture of ceramic powder and a binder into a mold.
This process is highly effective for creating complex shapes and is widely used for small-scale production.
After molding, the binder is removed, leaving behind the ceramic structure ready for sintering.

Laser Machining

Laser machining is utilized for precise shaping and cutting of ceramic materials.
It uses concentrated laser beams to etch, cut, or drill micro-sized features with high precision and minimal material wastage.
Laser machining is particularly advantageous for creating intricate designs in ceramic microfabrication.
