“…Hojo et al 20 reported a model of lateral pelvic lymph node dissection for training purposes, and showed that 3D printing was superior to textbooks for learning pelvic anatomy. In a recently reported meta-analysis, it was reported that education using 3D printing was more helpful in improving students' understanding 11 . In our study, students and residents compared 2D CT, 3D reconstruction, and 3D printing for understanding retroperitoneal tumors.…”

“…Therefore, there has been a demand for tools for intuitively visualizing and teaching anatomical structures. 3D printing can be applied to meet these needs because utilization of 3D printing in anatomical education could be a bridge of the large gap in experience by improving spatial comprehension of complex anatomy topics in a format that is widely accessible to most audiences 11 . In addition, caregivers are even less likely to understand lesions and surgery when they are explained by two-dimensional imaging alone 12 , 13 .…”

To investigate usefulness of 3D printing for preoperative evaluations, student and resident education, and communication with parents or guardians of patients with pediatric retroperitoneal tumors. Ten patients planning retroperitoneal tumor resection between March and November 2019 were included. Preoperative computed tomography (CT) images were used for 3D reconstruction and printing. Surveyed items were understanding of preoperative lesions with 3 different modules (CT, 3D reconstruction, and 3D printing) by students, residents, and specialists; satisfaction of specialists; and comprehension by guardians after preoperative explanations with each module. The median age at operation was 4.2 years (range, 1.8–18.1), and 8 patients were diagnosed with neuroblastoma. The 3D printing was the most understandable module for all groups (for students, residents, and specialists, P = 0.002, 0.027, 0.013, respectively). No significant intraoperative adverse events or immediate postoperative complications occurred. All specialists stated that 3D printing enhanced their understanding of cases. Guardians answered that 3D printing were the easiest to comprehend among the 3 modules (P = 0.007). Use of 3D printing in treatment of pediatric patients with retroperitoneal tumors was useful for preoperative planning, education, and parental explaining with obtaining informed consents.

“…Individual-case-speci c oncological surgery is based on the selection of safe landmark lines, removal of the entire tumor mass with a single surgical intervention, and removal of the intact tissue with a certain safety line [20,21]. Surgical interventions for tumors located in the brain involve risks and require different brain-speci c neuro-navigational calculations than tumors in other parts of the body [22][23][24](Figs. 1-5).…”

Surgical treatment of gliomas requires an intervention that does not leave residual tumor tissue in the brain and preserves functional centers. Although orientation parameters are not present in the traditional-MRI navigation information calculated from MRI, poor mans are observed for the neuro-oncological surgery in most parts of the world. The aim of this study is to obtain instant personalized neuro-navigational information through a 3D-patient-specific model to perform functional resection of the brain. 20 patients diagnosed with gliomas were included in this study. Neuro-oncological navigation calculations of 10 patients were carried out with traditional-MRI support and the remaining 10 with the 3D-model. In this way, the actual size of the tumor, its distance from cortical structures, and perioperative surgical planning were made by the 20 neurosurgeons based on the patient-specific model. They were required to compare their perception level of the cases with traditional-MR and 3D-models in terms of identifying the invasion of the mass, making the proximity to functional centers and anatomical structures as part of perioperative planning. All neurosurgeons have given higher scores for 3D-model supported neuro-navigations. 80–90% of them preferred the model in preoperative planning as they are beneficial in anticipating determining and envisaging the entire process of the functional resection covering the location and extent of craniotomy, the extent of tumor resection on functional areas. For this, orientation parameters of the neuro-navigation information such as tumor size, margin size of surgical resection, presence of functional areas in the gyrus/sulcus where the tumor is located, proximity of the tumor, anatomical structures as (ventricles, arteries, veins, myelinated pathways, capsula interna, basal ganglia) should be included. It also target the perioperative advantages of 3D supported neuro-navigational information over the traditional method.

“…Examples include the printing of protein models where students use them to better visualize the interaction between basic/acidic amino acids, hydrophobic groups, and solvent molecules, the printing of molecules and extended solids used to understand symmetry and point groups using crystallographic information files and protein databank files, the printing of microfluidic devices to demonstrate laminar flow, diffusional mixing, and parabolic flow, and printing laboratory equipment used in a plasma physics laboratory . Other examples are found in more specialized programs such as dentistry and medicine. − 3D printers are found on university campuses, typically in maker spaces that aim to provide an introduction to the technology and enable students to prototype devices for projects in mechanical engineering, for example.…”

Upper-division undergraduate students are introduced to polymer processing using material extrusion fused filament fabrication 3D printing to make poly(lactic acid) (PLA) mechanical testing specimens. Computer aided design and slicing software packages are used to demonstrate the process of preparing 3D computer models for printing. Following the introduction of the relevant ASTM standards, mechanical testing specimens are created by using a commercially available desktop printer to introduce tensile, compact tension, and impact resistance testing. Using two different polymer processing parameters, the weaker 90° and stronger 0° raster angles, students rationalize the high degree of anisotropy observed in printed thermoplastic objects. In the 90° orientation, stress is transferred across “welds” or the interfaces between tracks of deposited material, whereas in the 0° orientation, stress is transferred along continuous tracks of material. Using MatLab and the results from basic rheological testing, a nonisothermal degree of healing model is coded to understand why printed objects tend to fail at the welds. Thermogravimetric analysis and differential scanning calorimetry are used to obtain the key material properties of PLA that are needed for modeling. Fracture surfaces are visualized using optical microscopy following mechanical testing to better understand the failure mechanism and to visualize void spaces formed between tracks of the material. The students are evaluated individually by using a written technical report to assess their ability to synthesize the data from many lab activities into a logical sequence to convey their results. The modularity of the laboratory makes it amenable to instructors across a wide variety of disciplines and institutions.
