“…The history of 3D printing is relatively recent, dating back to the 1980s. Significant technological developments have taken place over the years ( Figure 1 ), culminating in the development of Spritam ® , the first commercial 3D-printed oral drug to be approved by the FDA in 2015 [ 2 ]. Two years later, the FDA published “Technical Considerations for Additive Manufactured Medical Devices”, a guide for industry and Food and Drug Administration staff, and progress still continues in this promising area [ 3 ].…”

The aim of this review is to present the factors influencing the mechanical properties of 3D-printed oral dosage forms. It also explores how it is possible to use specific excipients and printing parameters to maintain the structural integrity of printed drug products while meeting the needs of patients. Three-dimensional (3D) printing is an emerging manufacturing technology that is gaining acceptance in the pharmaceutical industry to overcome traditional mass production and move toward personalized pharmacotherapy. After continuous research over the last thirty years, 3D printing now offers numerous opportunities to personalize oral dosage forms in terms of size, shape, release profile, or dose modification. However, there is still a long way to go before 3D printing is integrated into clinical practice. 3D printing techniques follow a different process than traditional oral dosage from manufacturing methods. Currently, there are no specific guidelines for the hardness and friability of 3D printed solid oral dosage forms. Therefore, new regulatory frameworks for 3D-printed oral dosage forms should be established to ensure that they meet all appropriate quality standards. The evaluation of mechanical properties of solid dosage forms is an integral part of quality control, as tablets must withstand mechanical stresses during manufacturing processes, transportation, and drug distribution as well as rough handling by the end user. Until now, this has been achieved through extensive pre- and post-processing testing, which is often time-consuming. However, computational methods combined with 3D printing technology can open up a new avenue for the design and construction of 3D tablets, enabling the fabrication of structures with complex microstructures and desired mechanical properties. In this context, the emerging role of computational methods and artificial intelligence techniques is highlighted.

“…Different 3D printing technologies have been described in the literature to prepare 3DP pills [14][15][16][17]. Fused deposition modelling (FDM) and Semi Solid Extrusion (SSE) are the most straightforward technologies to prepare different mixtures and combinations Pharmaceutics 2021, 13, 907 2 of 16 of drugs and excipients, where the active pharmaceutical ingredient (API) is directly blended with or impregnated in the excipient/carrier to subsequently be processed.…”

Three-dimensional printed drug development is nowadays an active area in the pharmaceutical industry, where the search for an appropriate edible carrier that permits the thermal processing of the mixture at temperature levels that are safe for the drug is an important field of study. Here, potato starch and hydroxypropyl cellulose based mixtures loaded with paracetamol up to 50% in weight were processed by hot melt extrusion at 85 °C to test their suitability to be thermally processed. The extruded mixtures were tested by liquid chromatography to analyze their release curves and were thermally characterized. The drug recovery was observed to be highly dependent on the initial moisture level of the mixture, the samples being prepared with an addition of water at a ratio of 3% in weight proportional to the starch amount, highly soluble and easy to extrude. The release curves showed a slow and steady drug liberation compared to a commercially available paracetamol tablet, reaching the 100% of recovery at 60 min. The samples aged for 6 weeks showed slower drug release curves compared to fresh samples, this effect being attributable to the loss of moisture. The paracetamol loaded mixture in powder form was used to print pills with different sizes and geometries in a fused deposition modelling three-dimensional printer modified with a commercially available powder extrusion head, showing the potential of this formulation for use in personalized medicine.

“…FDM i.e. Fused Deposition Modelling is one of the many 3D printing processes available that serves the purpose [7,8,9], moreover, inkjet printing, selective laser sintering [10] are already been utilized effectively in personalized medicine and have showed tremendous promise [11]. The leading advanced manufacturing technology [12,13] applied to customized oral dosage forms has been fused deposition modelling 3D printing.…”

Aloe-Vera or Aloe barbadensis (botanical name) is a plant with many medicinal properties and have great importance in Ayurveda. Its leaves are succulent, erect, forming a thick rosette. The internal translucent pulp of Aloe-Vera is bound to a waxy crust or cuticle, and its vascular tissues transport minerals as well as water from the soil. Aloe Vera is being used as a major skin rejuvenating product, although it has varied medicinal properties also. In the present study, an attempt to make a method to create bi-layer tablets of Aloe-Vera, utilizing 3D printing techniques is presented. The method created doesnt affect the integral functional characteristics of the tablet. The method here contains creating an immediate release and sustained release tablet for making the Aloe-Vera to be used directly by the person for its numerous health effects. The tablet is designed so to be consumed by vegans as well since it is completely herbal.
