“…Common advantages of MJP include the use of transparent material (revealing the internal geometry) and dissolvable support material allowing detailed features to be easily cleaned [3, 7]. Other work has investigated low cost FFF methods [7, 8], but have not been able to create models of equivalent utility to the state-of-the-art. For example, Scott et al [8], demonstrated a low-cost FFF kidney model which separated into two parts to make-visible a tumor.…”

“…Fused filament fabrication (FFF) is a low-cost printing method but is limited for surgical planning models as it cannot print complex 3D geometries without support materials and it lacks transparent materials options [2, 8]. These are desired in surgical planning models as they allow the surgeon to view the internal anatomy of the organ.…”

3D printed, patient-specific anatomical models have been demonstrated as effective tools for preoperative training, especially in complex surgeries involving rare cases or unique anatomy. Current, state-of-the-art solutions are expensive, requiring 3D printers with large capital and operating costs, making them impractical for common usage and less likely to be adopted in healthcare settings. Alternatively, models fabricated using low-cost printing techniques, like fused filament fabrication (FFF), fail to achieve the utility of their more expensive counterparts. To overcome this challenge, we have developed an innovative approach using FFF that is able to partition the model into separate segments, held together with magnetic fasteners, to unveil the internal anatomy of the model thereby overcoming the challenges of low-cost printing methods and providing equivalent efficacy to the state-of-the-art. Notably, our models can be printed significantly faster and cheaper than other published models and can be viewed holistically as one model, or can be physically expanded into slices (like a deck of cards) whilst maintaining the entire model integrity. By dramatically reducing cost and time, our solution unlocks the potential of 3D printed patient specific models, making these practical for hospital usage.

Objectives: To evaluate the role of three-dimensional (3D) reconstruction in preoperative planning for complex renal tumors. Materials and Methods: A well-planned questionnaire was distributed among the attending urologists at an international meeting. The questionnaire inquired about demographic data, surgical experience, partial nephrectomy (PN) versus radical nephrectomy (RN), surgical approach, time of ischemia, probability of postoperative urine leakage and positive surgical margins after viewing computed tomography (CT) scans and their respective 3D models of six complex renal tumors. Following the CT scans, attendees were asked to view randomly selected reconstructions of the cases. Results: One hundred expert urologists participated in the study; 61% were aged between 40 and 60 years. Most of them (74%) were consultants. The overall likelihood of PN after viewing the 3D reconstructions significantly increased (7.1±2.7 vs. 8.0±2.2, p<0.001), the probability of conversion to RN significantly decreased (4.3±2.8 vs. 3.2±2.5, p<0.001), and the likelihood of urine leakage and positive surgical margins significantly decreased (p<0.001). Preference for the open approach significantly decreased (21.2% vs. 12.1%, p<0.001), while selective clamping techniques significantly increased (p<0.001). After viewing the 3D models, low expected warm ischemia time and estimated blood loss were significantly preferred by the respondents (p<0.001). Surgical decision change was significantly associated with performance or participation in more than 20 PNs or RNs annually [3.25 (1.98-5.22) and 2.87 (1.43-3.87), respectively]. Conclusions: 3D reconstruction models play a significant role in modifying surgeons' strategy and surgical planning for patients with renal tumors, especially for patients with stronger indications for a minimally invasive and/or nephron-sparing approach.
