3D printing of organic and inorganic materials requires special consideration in both material selection and the process used. This article provides an overview of the the six major processes used for 3D bioprinting: extrusion bioprinting, inkjet printing, selective laser sintering, stereolithography, laser-induced forward transfer bioprinting, and two-photon polymerization.

Techniques for the 3D printing of ceramics are evolving beyond product development and prototypes to enable full production-scale operations. This article gives examples of available methods and tradeoffs that must be addressed in developing 3D printing systems for ceramics.

The development of biocompatible resins and improvements in stereolithography are driving innovations in drug delivery, biosensing, diagnostic testing, and surgical devices and procedures.
