Abstract Freedom of design, mass customisation, waste minimisation and the ability to manufacture complex structures, as well as fast prototyping, are the main benefits of additive manufacturing (AM) or 3D printing. A comprehensive review of the main 3D printing methods, materials and their development in trending applications was carried out. In particular, the revolutionary applications of AM in biomedical, aerospace, buildings and protective structures were discussed. The current state of materials development, including metal alloys, polymer composites, ceramics and concrete, was presented. In addition, this paper discussed the main processing challenges with void formation, anisotropic behaviour, the limitation of computer design and layer-by-layer appearance. Overall, this paper gives an overview of 3D printing, including a survey on its benefits and drawbacks as a benchmark for future research and development.

Abstract The purpose of this study was to evaluate the mechanical properties of laser printed monolithic and laminated nano ceramic resins (NCR) for dental prosthetic applications. Three different types of discs were produced by laser printing: monolithic NCR discs and laminated NCR discs with 100 μm (laminate_100) and 500 μm (laminate_500) resin interlayers (n = 10). To assess the adhesion strength of the photosensitive resin used as interlayer to the NCR, cylindrical specimens were produced. T...

Abstract The layer printing sequence in three-dimensional (3D) printing affects the molecular structure of the printed layers, as shown for bottom-up stereolithography printing using an ultraviolet-curable acrylate ester resin. The first printed layer has less molecular alignment than the last printed layer, due to the longer ultraviolet exposure and consequent more curing in the former. Increasing the layer thickness from 12.4 to 26.3 μm decreases this effect, due to the greater molecular align...

Abstract Semi-crystalline polymeric composites are increasingly used as bearing material in the biomedical sector, mainly because of their specific mechanical properties and the new advances in 3D printing technologies that allows for customised devices. Among these applications, total or partial prostheses for surgical purposes must consider the influence of temperature and loading rate. This paper proposes a new constitutive model for semi-crystalline polymers, commonly used as matrix material...

Abstract This study proposes a new additive manufacturing (AM) based methodology to fabricate periodic metal matrix composite architectures, with a focus on titanium (Ti)-titanium boride whisker (TiB w ) composites. The manufacturing method includes binder jetting AM of the titanium matrix reinforced periodically by the extrusion of a custom-developed highly loaded resin, containing titanium di-boride (TiB 2) particles. A low-temperature pressure-less sintering method was then applied to increas...

Abstract Composite filaments with differing harakeke, hemp fibre or recycled gypsum contents (0-50 wt%) in pre-consumer recycled polypropylene (PP) were produced and mechanically assessed. Furthermore, a novel method of measuring shrinkage in 3D printed components was also developed and used to assess shrinkage of filaments. The most successful filaments contained 30 wt% harakeke fibre and had a tensile strength and Young's modulus of 39 MPa and 2.8 GPa respectively, providing improvements in te...

Elastic instability has been increasingly used to design buckling-induced auxetic metamaterials. However, only limited patterns of existing three dimensional (3D) buckling-induced auxetic metamaterials exhibit a reliable 3D auxetic behaviour, i.e., the material will contract along two normal lateral directions under compression along the third direction. In this paper, we study a simple geometrical shape for achieving 3D auxetic behaviour. The unit cell of the proposed 3D design is composed of a...

The development of sand mold three-dimensional printing technologies enables the manufacturing of molds without the use of a physical model. However, the effects of the three-dimensional printing process parameters on the mold permeability and strength are not well known, leading the industries to keep old settings until castings have recurring defects. In the present work, the influence of these parameters was experimentally investigated to understand their effect on the mold strength and perme...

Abstract WC is considered as a good choice for the reinforced phase of many composite alloys because of its excellent hardness and good wear resistance. In the past, micro WC particles physically mixed with micro metal particles were also widely used in laser cladding, however, micron WC particles often sink down to the bottom and may cause uneven element distribution, holes, cracks, and other defects in the cladding layer due to its high density and high laser absorption rate. Here, we prepare ...

Abstract Hastelloy X (HX) is a nickel-based alloy that is widely used in the aerospace and marine industries. HX alloy is susceptible to hot cracking, however, when it is processed through advanced additive manufacturing technologies such as selective laser melting (SLM) to form complex-shaped components. This study has revealed that microcracking could be mitigated by the addition of 2 wt% microscale TiB2 particles. The results show that the addition of 2 wt% TiB2 contributed to a 31% increase ...

Abstract In the past few years, tissue-engineered total disc replacement (TE-TDR) as a possible strategy to repair or regenerate intervertebral disc (IVD) has attracted considerable attention. However, to construct a patient-specific cell-based IVD scaffold with appropriate mechanical properties is still a challenge. The objective of this work is to develop stem cell-laden scaffolds mimicking the structure of native IVD. For this, an integrated 3D bioprinting system was used to combine polylacti...

Abstract Process monitoring and control is highly desired for additive manufacturing technologies. For aerosol jet printing, in particular, process drift and batch-to-batch variability have hindered widespread adoption beyond research environments. Addressing these key challenges is critical for emerging applications in multilayer, conformal, and 3D applications of this technology. Here, an in situ light scattering method is introduced to track the aerosol stream during printing, providing a rea...

Abstract To improve the multi-task scheduling competitivenesss of the distributed three-dimensional (3D) printing services with different types in cloud manufacturing, a non-cooperative game model of 3D printing services is proposed to reduce completion time, cost and to improve service quality. Moreover, the non-cooperative game consists of two kinds of sub-game to work together. Some service attributes, such as moving speed of nozzle, model dimension, 3D printing precision, 3D printing materia...
