This paper presents a hybrid additive manufacturing (3D Printing) process for fabricating functionally gradient materials. A multi-axis robot was integrated with microextrusion, picojet, and fiber laser systems to deposit conductive traces of different materials. Laser and furnace curing mechanisms were ...

reported a single-vat grayscale-DLP method and a two-stage curing ink to obtain functionally graded thermosetting materials15. However, DLP and SLA are often limited to light-curable resins and DSP can only print a certain selection of thermosetting inks with specific porosity (by generating ...
with PLA filaments with a diameter of 1.75 mm. The propulsion of the 3DP-motor was achieved based on the Marangoni effect by generating a surface tension gradient with asymmetric releasing of ethanol from the 3DP-motor tank. Simultaneously, a gradual discharge of the TiO2/Pt Janus ...
Several other projects addressed new, experimental approaches to 3DPF. The Vulcan Pavilion used small prefabricated polymer 3DPF modules that were partly filled with concrete to increase the stability and integrate an opacity gradient in a large-scale vaulted structure.64A different approach was taken ...
By definition, 3D-bioprinting is an additive manufacturing technology whereby the cells and biomaterials, such as hydrogel precursors (often referred as bioink), are simultaneously deposited in a layer-by-layer manner to generate biologically active 3D tissues of predesigned shape and size. ...
The left panel of Figure 8E presents a gradient refractive index (GRIN) lens composed of sub-elements with varied effective local permittivity values [100]. The blue region corresponds to a relatively low permittivity εl (made of ABS), and the white corresponds to a high permittivity εh (...
It should be noted 3D printing is not the only method to create materials/structures with functional gradient. For example, functional graded SMPs were demonstrated before52. However, by using multimaterial 3D printing technology, self-folding structures using digital SMPs with both spontaneous and ...
3D printing of liquid metal remains a big challenge due to its low viscosity and large surface tension. In this study, we use Carbopol hydrogel and liquid gallium-indium alloy to prepare a liquid metal high internal phase emulsion gel ink, which can be u
