“…Another approach involves surface functionalization of GO prior to the addition to photosensitive resin. Li et al [17] recently demonstrated that by grafting 2-hydroxyethyl methacrylate groups to the surface of the GO, improved dispersibility and interfacial compatibility of GO nanosheets with the photosensitive resin can be achieved.…”

“…More importantly, some group attempted to synthesize the stable GO/thermoset resin for SLA recently, but it involved the chemical functionalization of GO prior the mixing with the photopolymer resin. Furthermore, the resin itself also required pre-treatment with a number of chemicals [17]. Such processes make GO/thermoset resin synthesis not as user-friendly and readily accessible.…”

Graphene oxide (GO) induced enhancement of elastomer properties showed a great deal of potential in recent years, but it is still limited by the barrier of the complicated synthesis processes. Stereolithography (SLA), used in fabrication of thermosets and very recently in "flexible" polymers with elastomeric properties, presents itself as simple and user-friendly method for integration of GO into elastomers. In this work, it was first time demonstrated that GO loadings can be incorporated into commercial flexible photopolymer resins to successfully fabricate GO/elastomer nanocomposites via readily accessible, consumer-oriented SLA printer. The material properties of the resulting polymer was characterized and tested. The mechanical strength, stiffness, and the elongation of the resulting polymer decreased with the addition of GO. The thermal properties were also adversely affected upon the increase in the GO content based on differential scanning calorimetry and thermogravimetric analysis results. It was proposed that the GO agglomerates within the 3D printed composites, can result in significant change in both mechanical and thermal properties of the resulting nanocomposites. This study demonstrated the possibility for the development of the GO/elastomer nanocomposites after the optimization of the GO/"flexible" photoreactive resin formulation for SLA with suitable annealing process of the composite in future.

“…In addition, weak mechanical properties and deprived accuracy of stereolithography resin (SLR) are widespread problems for most desktop-level SLA techniques, restricting their utilization as functional materials [27]. For this reason, the development of mechanical behaviors of SLRs has been given attention in their applications [28,29]. To overcome this critical issue, many forms of research have been conducted, such as pre-treatment of SLA resin and incorporation of nanoparticles.…”

Fabrication of low-cost, durable and efficient metal oxide nanocomposites were successfully synthesized and reinforced with photo-resin via 3-dimensional printing. Here, we put forward a novel approach to enhance the mechanical and thermal behaviors of stereolithography (SLA) 3D printed architecture by adding TiO2 nanoparticles (TNPs) in different crystalline phases (anatase and rutile), which were obtained at different annealing temperatures from 400 °C to 1000°C. The heat-treated anatase TNPs were scrutinized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, diffusive reflectance spectroscopy (DRS), and transmission electron microscopy (TEM) analysis. Among all the samples, at 800 °C, annealed anatase TNPs exposed a highly crystalline anatase phase, having a low energy bandgap and a comparably high tensile strength (47.43 MPa) and high elastic modulus (2.261 GPa) for the 3D printed samples, showing improvement by 103% and 32%, respectively, compared with the printed pristine stereolithography resin (SLR) sample. Moreover, enhanced storage modulus and tan δ values were achieved via the better interfacial interactions between the incorporated nanofillers and the SLR matrix. In addition to this, enhanced thermal conductivity and thermal stability of the SLR matrix were also noted. The low energy bandgap and nanoscale size of the fillers helped to achieve good dispersion and allowed the UV light to penetrate at a maximum depth through the photo resin.

“…Due to its easy printing process and reliability, the most commonly used material in FDM is poly lactic acid (PLA). Other materials, such as acrylonitrile butadiene styrene (ABS), poly propylene (PP) and poly carbonate (PC), can be used as well . The main advantages of FDM printing are the low cost of the material and the straightforward printing process.…”

In laboratory environments, 3D printing is used for fast prototyping of assays and devices. Stereolithographic (SLA) 3D printers are proven to be the best choice for most researchers due to their small feature size, which is achieved by selectively curing liquid resin using a laser with a small focal point and then forming consecutive layers out of cured polymer. However, in microfluidic applications, where the limits of these machines are reached, the final results are influenced by many factors. In this work, the Form 2 SLA printer is tested to show how to achieve the best printing results for the creation of microfluidic channels. Several test structures are designed and printed with embedded and open channels in different orientations, sizes, and resins. Embedded channels significantly under perform when compared with open surface channels in terms of accuracy. Under the best printing conditions, 500 μm is the limit for embedded channels, whereas the open surface channels show good accuracy up to widths and depths of 250 μm.
