“…During the initial development of stereolithography, the technology was only limited to liquid photopolymers as raw material. The need to produce solid parts with high mechanical properties and functionalities motivated the researchers to incorporate micro and nano-size fillers inside the liquid photopolymer to cover a variety of applications [77,78]. Ceramic powders were one of the first choices as fillers due to their chemical inactivity with the organic resin, to produce non-functional prototypes.…”

“…DLP has also been exploited with composite-based photopolymers. Photopolymers reinforced with glass fibers, graphene nanoparticles, silicon carbide, zinc oxide, and multi-walled carbon nanotubes are used for manufacturing 3D objects with different functionalities [77]. Mu et al introduced multi-walled carbon nanotube (MWCNT)-based polymeric composites to produce electrically conductive objects, which can be used as capacitive sensors, stretchable circuits, and shape memory devices [43].…”

Additive manufacturing is a layer-by-layer strategy enabling the advanced design and fabrication of complex 3D objects and structures, overcoming geometry limitations and reducing waste production compared to conventional technologies. Among various additive manufacturing technologies, digital light processing (DLP), is an additive manufacturing technology used to print photopolymer parts, using a projected light source to cure an entire layer at once. Initially developed for pure resins, recent advances have demonstrated the potential of DLP in the polymerization of ceramic and metal-loaded suspensions, enabling the fabrication of ceramic and metal components after proper debinding and sintering. Such flexibility increases the potential of DLP for different applications, ranging from dental implants and bone scaffolds to smart biomaterials for soft robotics, smart wearables, and microfluidic devices. The review provides an overview of DLP technology and its recent advances; specifically, the review covers the photopolymer properties, the ceramic and metallic feedstock preparation, and the light-matter interaction mechanism underpinning the printing and post-processing steps. Finally, a description of the current application is provided and complemented with future perspectives.

“…[1][2][3][4][5][6] The structure is called 4D-printed (4DPed) structure only if it involves time as an additional dimension which allows it to transform its shape with time. [7][8][9] The additional dimension helps in changing the properties including functionality or shape of the 3D-printed (3DPed) products, over time in a controlled manner. [10][11][12][13][14] Computer-aided design models are applied to layer-by-layer deposit different smart materials (SMs) including polymers, metals, composites, and ceramics for developing extremely precise and intricate geometries.…”

Shape-memory materials (SMMs) combined with 3D printing to develop dynamic and adaptive products which are responsive to physical, chemical, or biological stimuli. These structures are categorized into 4D-printed (4DPed) products which change their shape and properties over time dimension. 4D printing, a novel, multidisciplinary, and futuristic technology is expanding its utilization in different applications including healthcare, space, textile, soft robotics, defence, sports, aerospace, and automotive sectors. This review article focuses on the recent and insightful developments in the 4DP technology of SMMs especially shape-memory polymers. This review also integrates printing technologies, the programming of materials for specific actuating mechanisms, and the most recent applications of 4DPed structures/products. Future perspectives and countless opportunities of this 4DP technology are outlined to address the current challenges which will help evolve and promote this novel technology as the mainstream manufacturing approach for developing real-world products in a myriad of engineering sectors. 4DP technology progresses beyond imagination, since its inception and will promote technological and manufacturing renaissance in the material science field. This technology will profoundly impact manufacturing and daily human life in the future.

“…Polymeric materials [ 45 ], as well as polymer nanocomposites, have lately received considerable attention in FFF 3DP [ 46 ], since they could offer a facile approach to improving the 3DP part’s properties; for instance, (i) the quasi-static, dynamic, and thermomechanical properties of the host polymeric matrix [ 47 ], (ii) nano-inclusions could induce crystallization of the polymer matrix, especially for semi-crystalline polymers, with the nanofillers functioning as nucleating agents, which can have a positive effect then on the mechanical properties, the thermal stability, etc. [ 48 ], and (iii) 3DP parts with multi-functional properties, e.g., sensing, electrical, optical, actuation, etc., can be realized [ 49 ].…”

Three-Dimensional Printed Polyamide 12 (PA12) and Polylactic Acid (PLA) Alumina (Al2O3) Nanocomposites with Significantly Enhanced Tensile, Flexural, and Impact Properties

The effect of aluminum oxide (Al2O3) nanoparticles (NPs) as a reinforcing agent of Polyamide 12 (PA12) and Polylactic acid (PLA) in fused filament fabrication (FFF) three-dimensional printing (3DP) is reported herein for the first time. Alumina NPs are incorporated via a melt–mixing compounding process, at four different filler loadings. Neat as well as nanocomposite 3DP filaments are prepared as feedstock for the 3DP manufacturing of specimens which are thoroughly investigated for their mechanical properties. Thermogravimetric analyses (TGA) and Raman spectroscopy (RS) proved the nature of the materials. Their morphological characteristics were thoroughly investigated with scanning electron and atomic force microscopy. Al2O3 NPs exhibited a positive reinforcement mechanism at all filler loadings, while the mechanical percolation threshold with the maximum increase of performance was found between 1.0–2.0 wt.% filler loading (1.0 wt.% for PA12, 41.1%, and 56.4% increase in strength and modulus, respectively; 2.0 wt.% for PLA, 40.2%, and 27.1% increase in strength and modulus, respectively). The combination of 3DP and polymer engineering using nanocomposite PA12 and PLA filaments with low-cost filler additives, e.g., Al2O3 NPs, could open new avenues towards a series of potential applications using thermoplastic engineering polymers in FFF 3DP manufacturing.
