Architected lightweight, sound-absorbing, and mechanically efficient microlattice metamaterials by digital light processing 3D printing

Harnessing cavity dissipation for enhanced sound absorption in Helmholtz resonance metamaterials

“…21 In turn, numerous lattice structures also function as multi-layered HRs. These include dense truss lattices, 14,22 plate lattices with pores, 14,[23][24][25] and layer-by-layered perforated plate lattices. 15,26,27 As can be seen, Helmholtz resonance is regarded as one of the most effective and widely adopted mechanisms for sound absorption.…”

Development of digital light processing-based multi-material bioprinting for fabrication of heterogeneous tissue constructs

“…One advantage of DLP is the ability to make complex structures such as lattices, which have shown potential in acoustic and biomedical applications. [55][56][57][58] The developed process has shown its capability for building lattice structures with alternate arrangements of unit cells and small features in individual unit cells. More importantly, the printing quality was not compromised by the introduction of material switching.…”

Three‐dimensional multicellular biomaterial platforms for biomedical application

“…[ 117 ] As an emerging biological scaffold preparation technology, 3D printing technology can fully realize the accurate customization of the scaffold structure. At present, common 3D printing methods include extrusion, [ 118–120 ] stereo‐lithography (SLA), [ 121 ] digital light processing (DLP), [ 122 ] two‐photon polymerization, [ 118 ] ink‐jet printing, [ 117 ] and other technologies.…”
