Extrusion-based additive manufacturing (AM) has recently become widespread for the layer-by-layer fabrication of three-dimensional prototypes and components even with highly complex shapes. This technology involves extrusion through a nozzle by means plunger-, filament- or screw-based mechanism; where necessary, this is preceded heating feedstock material to reduce its viscosity sufficiently facilitate extrusion. AM offers greater design freedom, larger building volumes more cost-efficient production than liquid- powder-based processes. Although was originally developed polymeric filament materials, it now increasingly applied wide variety classes, including metallic, edible construction materials. in part thanks recent development AM-specific materials (AM materials), which that are not intrinsically suited extrusion, example because high melting points brittleness, combined other, usually can be readily extruded. paper comprehensively systematically reviews state art field extrusion-based AM, techniques individual challenges developments each class being developed. The includes material- process-centred suitability analysis comparison Prospective applications also briefly discussed.

Abstract Self‐healing ionic conductive hydrogels have shown significant potential in applications like wearable electronics, soft robotics, and prosthetics because of their high strain sensitivity mechanical electrical recovery after damage. Despite the enormous interest these materials, conventional fabrication techniques hamper use advanced devices since only limited geometries can be obtained, preventing proper conformability to complexity human or robotic bodies. Here, a photocurable hydrogel with excellent deformations based on semi‐interpenetrating polymeric network is reported, which holds remarkable properties (ultimate tensile 550%) spontaneous self‐healing capabilities, complete its damages. Furthermore, developed material processed by digital light processing 3D printing technology fabricate complex‐shaped sensors, increasing stress respect simple sensor geometries, reaching an exceptional pressure detection limit below 1 Pa. Additionally, used as electrolyte laser‐induced graphene‐based supercapacitor, then incorporated into 3D‐printed create self‐powered, fully integrated device. These findings demonstrate that using printing, it possible produce multifunctional, self‐powered appropriately shaped depending various applications, without bulky batteries.
