Green Light Vat‐Photopolymerisation for 3D Printing Hydrogels with Complex Lattice Structures
Advanced Materials Technologies, EarlyView.Green‐light vat‐photopolymerization (gDLP) at 514 nm enables high‐resolution 3D printing of water‐rich hydrogels (60% water) with 50 μm$\umu{\rm m}$ layer precision. This study pioneers a cost‐effective, modified desktop printer and novel bioresins to fabricate complex vascularized lattices.

Pick‐and‐Place Grippers with Tunable Adhesion from Capped Soft Hollow Pillar Structure
Advanced Materials Technologies, EarlyView.Mushroom‐shaped soft hollow pillars (SHPs) with a mushroom cap, or capped SHPs (C‐SHPs) are introduced for improved tunable adhesion under pneumatic actuation. The mushroom cap optimizes stress distribution and alters crack initiation on the contact interface, leading to significantly improved adhesion strength and tunability.

How to Manufacture Photonic Metamaterials
Advanced Materials Technologies, EarlyView.Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.
