Some of the most impressive architectural masterpieces of the past, such as the Cologne Cathedral or the Cathedral in Milan, have taken several centuries for their creation and have involved thousands of people. Today, a glossy office building in Dubai has been built or rather printed in just 17 days, with 29 workers involved. Three-dimensional printing has been identified as the Fourth Industrial Revolution and is increasingly replacing traditional construction methods. There is no doubt that 3D printing will affect the design and production of buildings. Does the fact that 3D printing can be used means that it should replace analog with digital construction?

Dimensional Printing

In the last decade, the range of applications of three-dimensional printing (3D printing) in surgery has been expanding. In traumatology, orthopedics and rehabilitation of injuries of the upper limbs, there is growing interest in creating splints and orthoses that can take into account the individual anatomical features of the human body. Traditional orthoses and splints are not always convenient and can lead to undesirable consequences such as pain, swelling, pressure, or even lack of therapeutic effect. The prospects of 3D printing technology in medicine from the beginning of its mass introduction, the features of modeling, manufacturing and application of means for immobilization of injuries and diseases of the upper extremities according to domestic and foreign publications over the past 5 years are considered. The data on the functionality of 3D-printed tire structures and orthoses used to immobilize the upper limb are analyzed in comparison with traditional methods of fixation. Three-dimensional images of patients with injuries obtained using computed tomography, magnetic resonance imaging or using a 3D scanner can be used to create virtual 3D models of the forearm, wrist, fingers of the patient, and 3D printing with these anatomical models allows you to create personalized tires and orthoses. Thanks to an individual approach and the use of various solutions, three-dimensional printing can be widely used in traumatology and orthopedics. As a result of this approach, it becomes possible to implement and effectively use a variety of solutions that will find support in healthcare.

We comment on the recent developments and problems of three-dimensional printing in cardiology. Since there are currently no standards or consensuses for 3D printing in clinical medicine and the technology is at its infancy in cardiology, it’s very important to detail the procedures to allow more similar studies to further our understandings of this novel technology. Most studies have employed computed tomography to obtain source data for 3D printing, the use of real-time 3D transesophageal echocardiography for data acquisition remains rare, so it would be very valuable and inspiring to detail the image postprocessing steps, or the reliability of the study results will be doubtful.

Three-dimensional printing is a rapidly developing area of technology and manufacturing in the field of oral surgery. The aim of this study was comparison of presurgical models made by two different types of three-dimensional (3D) printing technology. Digital reference models were printed 10 times using fused deposition modelling (FDM) and digital light processing (DLP) techniques. All 3D printed models were scanned using a technical scanner. The trueness, linear measurements, and printing time were evaluated. The diagnostic models were compared with the reference models using linear and mean deviation for trueness measurements with computer software. Paired t-tests were performed to compare the two types of 3D printing technology. A P value < 0.05 was considered statistically significant. For FDM printing, all average distances between the reference points were smaller than the corresponding distances measured on the reference model. For the DLP models, the average distances in the three measurements were smaller than the original. Only one average distance measurement was greater. The mean deviation for trueness was 0.1775 mm for the FDM group and 0.0861 mm for the DLP group. Mean printing time for a single model was 517.6 minutes in FDM technology and 285.3 minutes in DLP. This study confirms that presurgical models manufactured with FDM and DLP technologies are usable in oral surgery. Our findings will facilitate clinical decision-making regarding the best 3D printing technology to use when planning a surgical procedure.

Abstract Three-dimensional printing (3DP) provides a fast and easy fabrication process without demanding post-processing. 3D-bioprinting is a special class in 3DP. Bio-printing is the process of accurately 3DP structural design using filament. 3D bio-printing technology is still in the development stage, its application in various engineering continues to increase, such as in tissue engineering. As a forming material in 3D printing, many types of commercial filaments have been developed. Filaments can be produced from either natural or synthetic biomaterials alone, or a combination of the two as a hybrid material. The ideal filament must have precise mechanical, rheological and biological properties. Polycaprolactone (PCL) is specifically developed and optimized for bio-printing of 3D structures. PCL is a strategy in 3D printing to better control interconnectivity and porosity spatially. Structural stability and less sensitive properties environmental conditions, such as temperature, humidity, etc make PCL as an ideal material for the FDM fabrication process. In this review, we provide an in-depth discussion of current research on PCL as a filament currently used for 3D bio-printing and outline some future perspectives in their further development.

Although there have been remarkable advances in cartilage tissue engineering, construction of irregularly shaped cartilage, including auricular, nasal, tracheal, and meniscus cartilages, remains challenging because of the difficulty in reproducing its precise structure and specific function. Among the advanced fabrication methods, three-dimensional (3D) printing technology offers great potential for achieving shape imitation and bionic performance in cartilage tissue engineering. This review discusses requirements for 3D printing of various irregularly shaped cartilage tissues, as well as selection of appropriate printing materials and seed cells. Current advances in 3D printing of irregularly shaped cartilage are also highlighted. Finally, developments in various types of cartilage tissue are described. This review is intended to provide guidance for future research in tissue engineering of irregularly shaped cartilage.

Background: In cases with solid tumors, preoperative radiological investigations provide valuable information on the anatomy of the tumor and the adjoining structures, thus helping in operative planning. However, due to a two-dimensional view in these investigations, a detailed spatial relationship is difficult to decipher. In contrast, three-dimensional (3D) printing technology provides a precise topographic view to perform safe surgical resections of these tumors. This systematic review aimed to summarize and analyze current evidence on the utility of 3D printing in pediatric extra-cranial solid tumors. Methods: The present study was registered on PROSPERO—international prospective register of systematic reviews (registration number: CRD42020206022). PubMed, Embase, SCOPUS, and Google Scholar databases were explored with appropriate search criteria to select the relevant studies. Data were extracted to study the bibliographic information of each article, the number of patients in each study, age of the patient(s), type of tumor, organ of involvement, application of 3D printing (surgical planning, training, and/or parental education). The details of 3D printing, such as type of imaging used, software details, printing technique, printing material, and cost were also synthesized. Results: Eight studies were finally included in the systematic review. Three-dimensional printing technology was used in thirty children with Wilms tumor (n = 13), neuroblastoma (n = 7), hepatic tumors (n = 8), retroperitoneal tumor (n = 1), and synovial sarcoma (n = 1). Among the included studies, the technology was utilized for preoperative surgical planning (five studies), improved understanding of the surgical anatomy of solid organs (two studies), and improving the parental understanding of the tumor and its management (one study). Computed tomography and magnetic resonance imaging were either performed alone or in combination for radiological evaluation in these children. Different types of printers and printing materials were used in the included studies. The cost of the 3D printed models and time involved (range 10 h to 4–5 days) were reported by two studies each. Conclusions: 3D printed models can be of great assistance to pediatric surgeons in understanding the spatial relationships of tumors with the adjacent anatomic structures. They also facilitate the understanding of families, improving doctor–patient communication.

Aggressive vertebral hemangioma (AVH) is a type of non-neoplastic and congenital developmental abnormality of spinal cord blood vessels. We report the innovative application of three-dimensional (3D) printing-assisted anterior and posterior combined surgery for treating a giant AVH. This could be a novel treatment in the future. A 44-year-old man suffered from persistent neck pain and limited limb mobility for approximately 2 weeks. An imaging examination showed the destruction of C2–4 vertebral bodies, and a giant lesion invaded the spinal cord. He underwent 3D printing-assisted anterior and posterior combined surgery. Postoperatively, his symptoms of persistent neck pain and limited limb mobility were alleviated. An imaging examination showed that internal fixation and the prosthesis were fixed in place, and the spinal canal was unobstructed. Treating a giant AVH by 3D printing-assisted anterior and posterior combined surgery is feasible and effective.
