Wavelength Selective Multi‐Material 3D Printing of Soft Active Devices Using Orthogonal Photoreactions

Inside Cover: In article 2200586, Sandra Schlögl and co-workers demonstrate that Acrylate functional coumarin monomers are synthetized cured by wavelength orthogonal photoreactions yielding soft (405 nm) stiff (365 networks. Advancing from thin films, the dual 3D printing of active devices is demonstrated with locally controlled mechanical thermal properties using a single vat. The concept highly versatile applicable to acrylate thiol-acrylate photopolymers.
