Advantages and drawbacks of the most common 3D printing techniques.

Technique	Advantages	Disadvantages
Stereolithography (SLA)	High precision Medical-grade materials	Moderate strength Small size models at low cost Expensive materials
Polyjet	High precision Medical-grade materials Very flexible models	Low strength and temperature resistance High cost Low durability
Fused Deposition Modeling (FDM)	Low cost Large size High resistance	Low speed Low reliability Medium flexibility of models
