Various requirements raised by actual applications in different fields for 3D printing have provoked its rapid development in technologies together with various specific materials. A protocol, combining 3D printing with surface modification, is standing out recently due to its outstanding capability to meet requirements in the fields where surface properties are critical by controlling the surface performance of the 3D printed architectures. The so-called surface functionalized 3D printing, by adding a new functional dimension to the surface of 3D printed objects, is believed to be robust, time-saving, cost-effective, and highly desirable approach for 3D printing meeting a variety of demands, compared to solely developing special-purpose material for each. The general strategy and the methods including etching, deposition processing, micro-nano composition coating, and polymer brush assisted surface modification are summarized in this review, and as well as the various applications and feasibilities in biomedicine, engineering, flexible electronics, smart devices and so forth, due to the acquired features originating from the postprocessing, including the wettability, the biocompatibility and bioactivity, high strength, and the conductivity etc.

Abstract Combination of porous catalyst carriers and high-performance catalysts has attracted increasing attention due to their efficient, reusable and durable characteristics in water purification. Herein, we report a design of three dimensional printed hierarchical porous ceramics that can in-situ load metal-organic frameworks-based catalysts by facile hydrothermal treatment. The resultant supported catalysts with hierarchical features are capable to completely decompose organic dyes based on ...

Abstract Patterning complex metallic structures via additive manufacturing (AM) has broad applications in energy, medical and aerospace industries. Current AM methods are often limited by high processing temperature, discontinuous film deposition and/or low product conductivity and reflectivity. We present a versatile room-temperature metal printing technique based on polymer-assisted photochemical deposition (PPD). Two-dimensional (2D) and three-dimensional (3D) printing of silver, gold and pla...

Abstract Jaw bone repair requires scaffold with bone regeneration, antibacterial function and personalized size. This study proposed 3D printed degradable calcium phosphate scaffolds with antibacterial functions for regeneration of jaw bone. Calcium phosphate powders and berberine were combined to modulate the printing inks. Porous scaffolds were fabricated by direct extrusion 3D printing and cross-linked with sodium alginate in situ. The dimensional size, shape and porosity of scaffolds were pr...

Three-dimensional (3D) printing can create complex geometries that could be of use in the development of electronics. However, the approach is mainly limited to non-functional structural materials, and the 3D printing of electronic devices typically requires multiple process stages of embedding, spraying and writing. Here, we report a 3D printing approach that can volumetrically deposit multiple functional materials within arbitrary 3D layouts to create electronic devices in a single step. Our a...

For this work, an integrated system composed of a polypropylene reactor and a palladium on silica monolithic catalyst was designed and manufactured by 3D-printing. These devices are able to perform solution phase chemistry in a robotic orbital shaker. The capped reactor was obtained in its entirety by 3D-printing, using polypropylene and fused deposition modeling. The monolithic catalyst was also obtained by 3D-printing -robocasting- of a silica support, sintering and subsequent palladium deposi...

Abstract Additive manufacturing, also known as 3D-printing, is receiving great interest by chemists due to the easy design of novel materials, fast prototyping and reducing waste, which enables large-scale fabrication of electrochemical devices. Herein we demonstrate the development of (bio)sensors for the analysis of biological fluids using 3D-printing. Fused deposition modelling was used to fabricate (bio)sensing platforms from commercially-available filaments made of polylactic acid containin...

So far, microdevices for oral drug delivery have been fabricated as square or cylindrical reservoir structures with a localized and unidirectional release. The fabrication is usually carried out using sophisticated and costly microfabrication techniques. Here, 3D printing of microreservoirs on sacrificial substrates is presented. This approach allows the devices to be accurately arranged in pre-determined patterns, enabling implementation into batch production schemes in which the fabrication of...

Additive manufacturing or, as also called, three-dimensional (3D) printing is considered as a game-changer in replacing traditional processing methods in numerous applications; yet, it has one intrinsic potential weakness related to bonding of layers formed during the printing process. Prior to finding solutions for improvement, a thorough quantitative understanding of the mechanical properties of the interface is needed. Here, a quantitative analysis of the nanomechanical properties in 3D print...

With the microfluidics community embracing 3D resin printing as a rapid fabrication method, controlling surface chemistry has emerged as a new challenge. Fluorination of 3D-printed surfaces is highly desirable in many applications due to chemical inertness, low friction coefficients, antifouling properties, and the potential for selective hydrophobic patterning. Despite sporadic reports, silanization methods have not been optimized for covalent bonding with polymeric resins. As a case study, we ...

Techniques of additive manufacturing commonly referred to as 3D-printing (3DP), obviously have taken a permanent place in the analytical chemistry laboratory toolbox. In the recent five years, one could observe the rapid spread of 3DP in several areas, especially in the instant design, prototyping, development, and final fabrication of custom analytical systems, which was not possible with the help of previously available laboratory methods. The two most achievable technologies: fused deposition...

Abstract Recent developments in three-dimensional printing (3DP) have attracted the attention of analytical scientists interested in fabricating 3D devices having promising geometric functions to achieve desirable analytical performance. To break through the barrier of limited availability of 3DP materials and to extend the chemical reactivity and functionalities of devices manufactured using conventional 3DP, new approaches are being developed for the functionalization of 3D-printed devices for...
