CeramicsDefinition• Inorganic• Nonmetallic Solid• Most elements• Most bonding types• All levels of
crystallinity
Properties• Aesthetics• High Melting Temp.• High Hardness• High Elastic Modulus• High Chemical
Resistance• Low Conductivity
(electric & thermal)
NB: There are exceptions to every rule
Ceramics: Production Methods
- Off the shelf
- Filament
- Powders
- Inhibitors
Ceramics: Processing Methods
- Porous vs. Dense- Extrusion- Sintering
- (SLA, SLS, SIS, SLM, SLB) - Jet Methods- Self-glazing- EBM?-
Ceramics: Performance
- Biomedical
- Aerospace
- Construction
- Electronics
- Other
Ceramics: Challenges
- Feedstock Preparation

- Current Technology
NanomaterialsDefinition• Any material having
a structure that has been designed at the nanoscale. - ISO
• Commonly 1-100 nano-meters.
Properties• Adjust size to find
new properties• Strength • Carrier Charge
Mobility• Flexibility• Super Lubricity
Nanomaterials: Production Methods
Bottom-up (miniaturization: self-assembly)-Laser Ablation, Pulse Femtosecond Laser-Arc, Combustion, Limiting Growth Solution-Chemical Vapor Precipitation
Top-down (macroscopic pattern)-Cutting, grinding-Lithography-Solution Phase Exfoliation
Nanomaterials: Processing Methods
- FDM/FFF- Sintering Techniques- Two Photon Fabrication- Aerosol Jet- Laser Inducted Forward Transfer
- LIFT
Nanomaterials: Performance- Biomedical- PCB- Flexible/Disposable Electronics- Wi-Fi- Photovoltaic- Batteries- Passive Sensors (Quantum Entanglement)
Nanomaterials: Challenges- Compatibility - Cost- Environmental Stability- Dispersal- Processing Conditions- H&S?
