“…Additive manufacturing (AM), which is also widely known as 3D printing, has attracted a great amount of attention over the last few years due to its capability to create complex 3D geometries with desired performance, leading to applications in various fields such as biotechnology [1], landslide modeling [2], medical applications [3], conductive devices [4], and sensors [5]. Several types of 3D printing can be found depending on their printing mechanism, for instance, selective laser melting, which utilizes thermal energy to selectively melt or sinter certain appointed molten pools of a powder bed [6], and stereolithography (SLA), which transforms liquid monomers into solid polymers utilizing a UV laser to trace and cure successive points from the photosensitive resin.…”

A solvent-free method to fabricate graphene-reinforced nanocomposites in net shape via digital light processing (DLP) 3D printing has been developed in this work. The effect of graphene nanofillers on resin viscosity and wettability for various printing parameters has been examined, with a systematic characterization of the mechanical and thermomechanical properties. With the addition of 0.5 wt.% graphene nanoplatelets in the resin, the flexural modulus and fracture toughness have been improved by 14% and 28% from neat resin, respectively. Thermomechanical properties of graphene-reinforced nanocomposites were also enhanced compared with the neat resin, without scarification in their printability. The feasibility of utilizing the DLP method to fabricate a fracture toughness specimen (KIC test) without complex skill-dependent notch preparation steps was explored, with different notch tip angles printed for net-shaped specimens. This provided a simple and versatile way to perform a quick examination of reinforcing efficiency from nanofillers at very low cost with high resolution and reproducibility. To demonstrate the suitability of current resins for complexly shaped structures, a gyroid scaffold for tissue engineering applications based on current graphene nanocomposite resins has been successfully fabricated via DLP, showing the great potential of current photocurable resins for applications in various fields such as tissue engineering or personalized medical devices without the cost barriers of traditional methods.

“…During the process of AM, a computer-aided design (CAD) software is utilized to build a 3D model object. A wide range of materials, such as metals, polymers, ceramics or even concrete, can be successfully transformed into products using AM [25,26] Multi-structured graphene-based composites produced via AM have many merits. With the aid of computer aided design or optimization, components or products are reproducible and can be precisely fabricated with highly complex architectures in high resolution, meeting various end-user requirements.…”

“…The inner force along the shear layer commences when the gravitational force exceeds the cohesive and resisting frictional forces. Therefore, controlling the stress and seepage fields and the porosity of the geological model has been the current simulation and manufacturing research content (Tang et al , 2018). Currently, the models manufactured by direct ink writing (DIW) were applied for simulation, showing the geological disasters and the similar bionic engineering models for simulating the accident disasters and security problems of construction like bridges or subways (Tang et al , 2020a, 2020b).…”

“…graphene, carbon nanotubes, organic synthetic resins and other materials (Zhong et al , 2017; Yao et al , 2010)]. With the development of geological simulation, complex and multi-structure model are not enough for requirements for imaging and detecting the geological model, which requires the multi-function like thermal imaging (Gong et al , 2015), anti-corrosion and porous structures (Tang et al , 2018; Tang et al , 2020b) to reproduce the high-temperature geological area. Coupled with the good thermal conductivity of diamonds, a 3D printing micron diamond-based geopolymer presents the potential to thermal imaging or simulation in geological model and detection (Gong et al , 2015; Scafutto et al , 2017; Lee et al , 2016; Aranzabal et al , 2016), unclear waste coating (Matzke and Vernaz, 1993) and lightweight isolation heat transfer ceramic tiles (Sarikaya et al , 2005; Jadhav, 2016).…”

Purpose Traditional simulation research of geological and similar engineering models, such as landslides or other natural disaster scenarios, usually focuses on the change of stress and the state of the model before and after destruction. However, the transition of the inner change is usually invisible. To optimize and make models more intelligent, this paper aims to propose a perceptible design to detect the internal temperature change transformed by other energy versions like stress or torsion. Design/methodology/approach In this paper, micron diamond particles were embedded in 3D printed geopolymers as a potential thermal sensor material to detect the inner heat change. The authors use synthetic micron diamond powder to reinforced the anti-corrosion properties and thermal conductivity of geopolymer and apply this novel geopolymer slurry in the direct ink writing (DIW) technique. Findings As a result, the addition of micron diamond powder can greatly influence the rheology of geopolymer slurry and make the geopolymer slurry extrudable and suitable for DIW by reducing the slope of the viscosity of this inorganic colloid. The heat transfer coefficient of the micron diamond (15 Wt.%)/geopolymer was 50% higher than the pure geopolymer, which could be detected by the infrared thermal imager. Besides, the addition of diamond particles also increased the porous rates of geopolymer. Originality/value In conclusion, DIW slurry deposition of micron diamond-embedded geopolymer (MDG) composites could be used to manufacture the multi-functional geological model for thermal imaging and defect detection, which need the characteristic of lightweight, isolation, heat transfer and wave absorption.
