Introduction to Hybrid AM
Additive manufacturing (AM) has long relied on thermoplastics as the primary material for production. However, as the industry expands to more demanding applications, the limitations of thermoplastics are becoming increasingly apparent. Thermosets, a type of material commonly used in traditional manufacturing, are being explored as a potential solution.
Thermosets vs Thermoplastics
Thermosets and thermoplastics have distinct properties that make them suitable for different applications. Thermoplastics are easy to process and can be melted and reshaped multiple times, making them ideal for prototyping and production tooling. In contrast, thermosets are designed to hold their shape once cured and cannot be melted down and reshaped. This property makes them useful for applications where parts need to withstand high temperatures and heavy use over long periods.
Comparison of Thermosets and Thermoplastics
| Material | Properties | Applications |
|---|---|---|
| Thermoplastics | Easy to process, can be melted and reshaped | Prototyping, production tooling |
| Thermosets | Holds shape once cured, withstands high temperatures | Aerospace, defense, automotive |
