The manufacture of electric motors using additive methods offers potential advantages of increased efficiency, weight reduction, and customizability over traditional processes. This article describes some key developments and challenges related to additively manufactured electric motors in terms of manufacturing, materials development, and design.

Laser melting of elastocaloric metals can create fatigue-resistant microstructures, which enables solid-state cooling technologies.

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.

4D printing enables fabrication of complex objects that transform over time (the fourth dimension) when subjected to external stimuli. 4D printing of metallic functional materials is of special interest due to their capacity for self-assembly and multifunctionality, with the added benefit of higher actuation capability, in comparison with polymeric materials.

This article is a case study in using laser sintering additive manufacturing of PEKK (polyether-ketone-ketone) to manufacture a patient-specific cranial implant.

Laser sintering and numerical modeling play a major role in the development of a PEEK polymer surgical implant optimized for patient-specific cranial reconstruction.
