“…Examples include devices used at the point of care outside of the body such as bone cement molds [10]; devices that indirectly interact with patients such as ventilator components [11]; and devices that directly interact with a patient's external surface such as helmet orthoses [12]. Other novel, diverse uses of medical 3D printing include wheelchair cushions [13], adapters for medical sample acquisition [14], external bone fixation devices [15], CPAP masks for newborns [16], precise radiation therapy administration apparatus [17], customized facemasks for burn victims [18], and craniectomy defect helmets [19].…”

3D printing in Health Care Facilities (HCFs) has evolved from a set of experimental techniques and situational engineering applications employed at leading academic institutions to a relatively mature but expanding field with well-defined workflows and recognition at major medical societies. This project introduces the term 'Final Anatomic Representation' that refers to the final surface mesh files used in patient care. It also introduces the term 'Patient Specific Realization' to characterize how the Final Anatomic Representation is used, for example the creation of a 3D PDF, virtual reality display with shared experiences, augmented reality to include procedure simulation, or 3D printed parts. This project focuses on 3D printing in HCFs, and it includes a wide scope of use cases with literature support. Many intended uses have progressed to guideline support for appropriateness; these are organized by patient presentation or clinical scenario. One benefit of using clinical scenarios is that direct feedback can be translated from the engineering of 3D printed parts to the data generation from those parts used in the medical value equation. Continuing with the direct feedback, established value then supports guidelines for patient care such as clinical appropriateness, and those guidelines can then be applied to realize that value added for future patients who present with the same clinical scenarios.

“…The concept of 4D printing acknowledges time as a fourth dimension and enables printed structures to modify their structural morphology in response to any outside input [13][14]. Excipients manufacturing, also known as 3D printing, has emerged in recent years as a versatile technique and a priceless replacement for conventional manufacturing for the construction of multiple substances through such a layer-by-layer methodology, resulting in the development of various types of medical technology, wearable devices, scaffolds, actuators, soft robotics, and flexible electronics [15][16][17][18][19][20][21][22][23][24].…”

The development of patient-specific prosthetics, medication administration, the manufacture of tissues and organs, and surgical planning have all benefited significantly from the use of three-dimensional (3D) printing during the past few decades. The enthusiasm for customized healthcare has increased because the United States of America launched its Precision Medicine Initiative in 2015. In a nutshell, the phrase “personalized medicine” refers to medical care that is tailored to the patient. Nevertheless, the biomedical materials utilized in 3D printing are often stable and can’t react or be adaptive and intelligent in the body’s interior environment. Ex-situ fabrication of these substances, which includes printing on a flat substrate before releasing it onto the target surface, may cause a discrepancy between the printed portion and the target areas. The 3D printing is one method that might be used to provide customized treatment. The four-dimensional (4D) printing is developed while employing components that can be tweaked with stimulation. Several researchers have been looking at a new area recently that blends medicines with 3D and 4D printing. The development of 4D printing overcomes a number of these issues and creates a promising future for the biomedical industry. Smart materials that have been pre-programmed can be used in 4D printing to create structures that react interactively to outside stimuli. Despite these benefits, dynamic materials created using 4D technology remain in their development. As a result, several ideas for pharmaceutical products and formulas that may be customized and printed have emerged. Furthermore, Spritam®, the first medicine produced by 3D printing, has indeed reached a medical facility. This paper offers a summary of several 3D and 4D printing technologies and how they are used in the pharmaceutical industry for customized medicine and drug delivery systems.

In the last decades, 3D printing has played a crucial role as an innovative technology for tissue and organ fabrication, patient-specific orthoses, drug delivery, and surgical planning. However, biomedical materials used for 3D printing are usually static and unable to dynamically respond or transform within the internal environment of the body. These materials are fabricated ex situ, which involves first printing on a planar substrate and then deploying it to the target surface, thus resulting in a possible mismatch between the printed part and the target surfaces. The emergence of 4D printing addresses some of these drawbacks, opening an attractive path for the biomedical sector. By preprogramming smart materials, 4D printing is able to manufacture structures that dynamically respond to external stimuli. Despite these potentials, 4D printed dynamic materials are still in their infancy of development. The rise of artificial intelligence (AI) could push these technologies forward enlarging their applicability, boosting the design space of smart materials by selecting promising ones with desired architectures, properties, and functions, reducing the time to manufacturing, and allowing the in situ printing directly on target surfaces achieving high-fidelity of human body micro-structures. In this review, an overview of 4D printing as a fascinating tool for designing advanced smart materials is provided. Then will be discussed the recent progress in AI-empowered 3D and 4D printing with open-loop and closed-loop methods, in particular regarding shape-morphing 4D-responsive materials, printing on moving targets, and surgical robots for in situ printing. Lastly, an outlook on 5D printing is given as an advanced future technique, in which AI will assume the role of the fifth dimension to empower the effectiveness of 3D and 4D printing for developing intelligent systems in the biomedical sector and beyond.
