“…FDM is closely similar to SLA, and it was initially used for only 3D polymer structures. The FDM has been developed to produce ceramic, ceramic/polymer composites which is termed a fused deposition of ceramics [ 36 , 37 ]. For this technique, a word thermoplastic polymeric filament is used by unwinding and extruded via a hot nozzle onto a fabrication based.…”

There is a rising demand for replacement, regeneration of tissues and organ repairs for patients who suffer from diseased/damaged bones or tissues such as hip pains. The hip replacement treatment relies on the implant, which may not always meet the requirements due to mechanical and biocompatibility issues which in turn may aggravate the pain. To surpass these limitations, researchers are investigating the use of scaffolds as another approach for implants. Three-dimensional (3D) printing offers significant potential as an efficient fabrication technique on personalized organs as it is capable of biomimicking the intricate designs found in nature. In this review, the determining factors for hip replacement and the different fabrication techniques such as direct 3D printing, Fused Deposition Modelling (FDM), Selective Laser Sintering (SLS) and stereolithography (SLA) for hip replacement. The study also covers surface modifications of 3D printed implants and provides an overview on 3D tissue regeneration. To appreciate the current conventional hip replacement practices, the conventional metallic and ceramic materials are covered, highlighting their rationale as the material of choice. Next, the challenges, ethics and trends in the implants’ 3D printing are covered and conclusions drawn. The outlook and challenges are also presented here. The knowledge from this review indicates that 3D printing has enormous potential for providing a pathway for a sustainable hip replacement.

The practice of using a massive amount of environmental unfriendly and toxic petroleum-based materials in tissue engineering and biomedical fields demands the materials, which are biodegradable, renewable, environmentally friendly, biocompatible, and bioactive. So, renewable polymers have got considerable attention due to their numerous desirable properties. The nanofibers that are prepared from renewable materials and their blends can integrate the properties of both nanofibers and renewable polymers. Development of scaffolds that mimic the construction of tissues at nanoscale is a great challenge for tissue engineering. Electrospinning is the most promising technique for nanofibers formation. Nanofibers provide a platform for cell adhesion, proliferation, and differentiation. Therefore, nanofibers from sustainable materials have been used in tissue engineering and biomedical fields. In this review, methods for nanofibers fabrication, sustainable nanofibers made from natural and synthetic polymers and their applications in tissue engineering and biomedical field, have been emphasized.

“…In contrast, FDM employs thermoplastic solid filament which is dispensed from printer nozzle, the path of which is piloted by slicing software. FDM's rife presence is contributed by its low-cost and easy-handle nature which is ics which k most commonly practiced for polycarbonate, acrylo butadiene styrene, poly lactic acid, polyurethane and its composites [114,115]. Nonetheless, SLS and SLM are powder-based process whose densification is contributed by laser guide transferring energy in a nitrogen or argon atmosphere evading its contact with oxygen which initiates oxidation or other undesired reactions.…”

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.
