“…High-dimensional precision is obtainable with 3D scanning of existing products, and reverse engineering can be done to prepare the 3D model required for the 3D printing process [28]. A different way to create a 3D model is to segment DICOM files of the radiological images obtained from the patient with computed tomography or MRI and use softwares to reconstruct the cross-sectional images into 3D designs by the process of 3D rendering (surface rendering) [29]. 3D models produced from DICOM images by this way are obtained as the .stl file and are loaded into the 3D printer software and can be used in 3D printing.…”

COVID-19 disease caused by the SARS-CoV-2 virus has had serious adverse effects globally in 2020 which are foreseen to extend in 2021, as well. The most important of these effects was exceeding the capacity of the healthcare infrastructures, and the related inability to meet the need for various medical equipment especially within the first months of the crisis following the emergence and rapid spreading of the virus. Urgent global demand for the previously unavailable personal protective equipment, sterile disposable medical supplies as well as the active molecules including vaccines and drugs fueled the need for the coordinated efforts of the scientific community. Amid all this confusion, the rapid prototyping technology, 3D printing, has demonstrated its competitive advantage by repositioning its capabilities to respond to the urgent need. Individual and corporate, amateur and professional all makers around the world with 3D printing capacity became united in effort to fill the gap in the supply chain until mass production is available especially for personal protective equipment and other medical supplies. Due to the unexpected, everchanging nature of the COVID-19 pandemic-like all other potential communicable diseases-the need for rapid design and 3D production of parts and pieces as well as sterile disposable medical equipment and consumables is likely to continue to keep its importance in the upcoming years. This review article summarizes how additive manufacturing technology can contribute to such cases with special focus on the recent COVID-19 pandemic.

“…where a requisite design with dimensional specifications is recorded and synchronized with nozzle (in FDM) or image (in SLA) for printing [124]. With progress in material dispensing or laying, parameters such as printing speed, layer dimensions, orientation, layering time, shrinkage, porosity, temperature, laser depth and powder dimension are considered for effective printing [125]. Accounting all aforesaid factors, 3D printing is exploited in multifarious domains e.g.…”

Recent research in soft materials is an exhilarating category which has been transcending boundaries for variety of functional applications. This category also stems liquid crystals whose stimuli-responsive feature has fantasized researchers for application arrays in actuators and biomedical. Liquid crystals evince dual characteristics of liquid and solids empowering them to reversibly transit on external actuation. The after-effect of irradiating photons on liquid crystals (LC) facilitate outlying functioning and are engineered with gold nanorods, dyes, graphene and carbon nanotubes among others which greets to incoming stimulus and participates in transference of light energy to perceivable transformation through heat drive. This is progressively explored in medical domain for drug delivery, tissue engineering, cancer treatment, and other disciplines of medicine and bio-mimicking. Additionally, photothermal trigger equips localized punctilious treatment outshining diffusion assisted heating and enables spot treatment. However, LC utilization is burgeoning towards 3D printing, dyes ipa graphen sib tals (LC) bly tr quid crysta sit feature ha als nctio as f is an ex pli @gma ail.c manian K J, Un d eering, R ted Kin Rober e, Girinagar, characterizing it as 4D Printing. Present review framework probes LC and its photothermal actuation chemistry in the medical domain. Furthermore, it reflects on LC potential in smart manufacturing in 3D/4D printing, its challenges (limited concentration of filler, its miscibility, and actuation cycle fatigue) and future likelihood.

Purpose There is a rising demand for high-performance 3D printed objects that have established potential applications in the sector of dental, automotive, electronics, aerospace, etc. Thus, to meet the requirements of high-performance 3D printed objects, this study has synthesized, formulated and applied a resorcinol epoxy acrylate (REA) oligomer to a stereolithography (SLA) 3D printer. Design/methodology/approach Different formulations were developed by blending reactive diluents in the concentration of 10%, 15% and 20%, along with the fixed quantity of photo-initiators in the REA oligomer. The structure of synthesized REA oligomer was confirmed using 13 C nuclear magnetic resonance (NMR) and 1H NMR spectroscopy, and the rheological properties for prepared REA formulations were also evaluated. The ultraviolet (UV)-cured specimens of all REA formulations were thoroughly examined based on physical, chemical, optical, mechanical and thermal properties. The best suitable formulation was selected for SLA 3D printing. Findings As perceived, UV cured REA specimens exhibit superior mechanical, chemical and thermal properties, portraying the ability to use as a high-performance material. The increase in the concentration of reactive diluents indicated a significant improvement in the properties of REA resin. The 20% diluted formulation achieved excellent compatibility with a SLA 3D printer; thus, 3D objects are cast with good dimensional stability and printability. Originality/value Resorcinol-based resins have always been a key additive used to enhance properties in the coating and tire industry. In a new attempt UV, curable REA has been applied to a SLA 3D printer to cast high-performance 3D printed objects.
