Background Surgical management for intracranial and extracranial communicating tumors is difficult due to the complex anatomical structures. Therefore, assisting methods are urgently needed. Accordingly, this study aimed to investigate the utility of a three-dimensional (3D)-printed model in the treatment of intracranial and extracranial communicating tumors as well as its applicability in surgical planning and resident education. Methods Individualized 3D-printed models were created for eight patients with intracranial and extracranial communicating tumors. Based on these 3D-printed models, a comprehensive surgical plan was made for each patient, after which the patients underwent surgery. The clinicopathological data of patients were collected and retrospectively analyzed to determine surgical outcomes. To examine the educational capability of the 3D-printed models, specialists and resident doctors were invited to review three of these cases and then rate the clinical utility of the models using a questionnaire. Results The 3D-printed models accurately replicated anatomical structures, including the tumor, surrounding structures, and the skull. Based on these models, customized surgical approaches, including the orbitozygomatic approach and transcervical approach, were designed for the patients. Although parameters such as operation time and blood loss varied among the patients, satisfactory surgical outcomes were achieved, with only one patient developing a postoperative complication. Regarding the educational applicability of the 3D-printed model, the mean agreement for all eight questionnaire items was above six (seven being complete agreement). Moreover, no significant difference was noted in the agreement scores between specialists and residents. Conclusion The results revealed that 3D-printed models have good structural accuracy and are potentially beneficial in developing surgical approaches and educating residents. Further research is needed to test the true applicability of these models in the treatment of intracranial and extracranial communicating tumors.

“…In order to test the application of this new auxetic incision on the TA, a model study approved by our review board, using 2 previously published penile model simulators, [12][13][14] was performed to analyze the result of the auxetic incisions in different penile deformities.…”

“…Several other penile simulators with different deformities were also created (dorsal curvature, lateral curvature, and dorsal curvature with hourglass deformity [Software: Shapr3D, version 3.23, Hungary] using a 3D printed model. 12 The model was 3D-printed using a flexible filament of thermoplastic polyurethane with a diameter of 1.75 mm (GTMax3D, Core A3, Brazil) using a fused deposition modeling technique to test the semicircular application of the auxetic incisions for its capacity to correct geometric abnormalities. Finally, the results were illustrated (Adobe Illustrator, version 25.4.1, USA) for better visualization.…”

Introduction Several conditions can cause penile length and girth loss. Surgical techniques have been used to restore these penile alterations in patients with severe erectile dysfunction during penile prosthesis implantation. One technique uses multiple small incisions in a mesh pattern (similar to a skin mesh) with satisfactory curvature correction without using a graft, however, this technique does not allow simultaneous increase in penile length and girth. Aim To identify a new surgical technique that increases both the length and girth at the same place on the corpora cavernosa (CC), allowing a simultaneously longitudinal and transverse increase of the tunica albuginea. Methods A sheet with a star-shaped perforation was created using a mathematical model to allow a longitudinal and transversal increase in the material. Two previously published penile model simulators, with and without deformity, were used to test the mechanical modification of this incision pattern in the CC. Main Outcome Measure The effect of the incisions pattern on the geometry of the CC simulator. Results The star-shaped incision (auxetic) simultaneously increased the length, girth, and volume of the CC simulator. This auxetic technique could correct any penile deformity, re-establishing the original penile anatomy. The new auxetic incision is only a conceptual and experimental technique awaiting clinical evidence. Conclusion The data presented here show that the auxetic technique successfully increases both the length and girth at the same place on the CC simulators, opening a new potential solution to correct challenging cases of complex penile deformities and to restore volume loss.

Additive manufacturing is an emerging technology with the advantage of less wastage, fast prototyping with customized designing suitable for a wide range of applications. Three‐dimensional (3D) printing is one of the types of additive manufacturing and various polymers are explored for 3D printing applications. Thermoplastic polyurethane (TPU) is a versatile material that has gained increasing attention in 3D printing applications due to its unique combination of mechanical, thermal, and chemical properties. This review paper provides an overview of the current state‐of‐the‐art in TPU‐based 3D printing, including its characteristics, processing techniques, and mainly its applications. Extensive studies are done in TPU with fused deposition modeling (FDM), multi‐jet fusion (MJF), and selective laser sintering (SLS). The elasticity and flexibility, layer adhesion, tensile strength, and support structure are the parameters that decide the suitability of FDM, SLS, and MJF for TPU 3D printing. The infill density, modification of processing parameters, use of sacrificial materials, addition of perforations or channels, varying the particle size, using a mixture of powders, and so forth. leads to develop the porous structure in the final product. In addition, we have studied blends of TPU with other polymers like acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA), as well as fiber‐reinforced TPU composites for 3D printing applications.
