Aim: A limited number of studies have attempted to quantify the advantages of using in-house 3D printed models. We designed a pilot study to assess the value of in-house production of patient-specific 3D-printed models in pre-surgical planning. Methods: A 12-question survey was designed and sent to surgeons to assess any purported benefits of 3D-printed anatomic models. In-house 3D model printing was completed on a Stratasys J750 Polyjet printer. Each 3D printed model was delivered to the supervising surgeon days before the procedure for final validation. The 3D models were subsequently utilized in the operating room. Results: A total of 50 surveys were completed for a response rate of 100%. Approximately 94% of the participants strongly agreed that the 3D-printed model was a valuable clinical tool for pre-surgical planning. The majority of the respondents (78%) reported improved surgical efficiency. Conclusion: 3D models is a valuable tool for surgical planning.
目的:数量有限的研究试图量化使用内部 3D 打印模型的优势。我们设计了一项试验性研究,以评估内部制作患者特异性 3D 打印模型在手术前规划中的价值。方法:设计并向外科医生发送了一份包含 12 个问题的调查问卷,以评估三维打印解剖模型的所谓益处。使用 Stratasys J750 Polyjet 打印机完成了内部 3D 模型打印。每个 3D 打印模型都在手术前几天交付给主管外科医生进行最终验证。随后在手术室中使用这些三维模型。结果:共完成 50 份调查问卷,回复率为 100%。约 94% 的参与者强烈同意三维打印模型是手术前规划的重要临床工具。大多数受访者(78%)表示手术效率有所提高。结论:3D 模型是手术规划的重要工具。

With the increasing complexity and difficulty of surgical procedures, there is an urgent need for empirical and high-fidelity surgical teaching tools. Whereas in the past, teaching tools included cadavers and animals, today, with the development of three-dimensional (3D) printing technology, the creation of patient-specific organ models is possible. This technology provides an effective solution for preoperative rehearsal, thus providing surgery residents with a more realistic simulation environment. This study aimed to provide an overview of the use of personalized 3D printing in various types of surgery through a scoping review, outline their bottlenecks, and provide an outlook. Significant advancements have been made in 3D-printed gel organ models for surgical applications. However, future advancements require interdisciplinary collaborations, medical–engineering integration and novel techniques. Addressing challenges in preservation, instrument response, ultrasound performance and mechanical properties is crucial. Enhancing these aspects will improve the capabilities of organ models, benefiting both medical practitioners and patients.

With significant contributions to the field of 3D bioprinting, Ibrahim's research focuses on the generation of 3D-printed tissues and organs and the development of 3D bioprinting processes and related technologies for a range of purposes including regenerative medicine, drug testing and understanding of diseases. He serves as the principal investigator of the Ozbolat lab, an interdisciplinary lab drawing on experts from various backgrounds including medicine, chemistry, biomedical engineering, industrial engineering and mechanical engineering. This collaborative approach fosters innovation and seeks to address complex challenges in 3D bioprinting.What inspired your interest in bioprinting?I hold dual Bachelor of Science degrees from the Middle East Technical University (Ankara, Turkey), where my primary interest during my degree was manufacturing. During a visit to a center in the university, I came across a 3D printer that was printing inert materials for fabrication of 3D objects, specifically plaster. It was fascinating because it was my first time seeing complex structures being manufactured. So, this sparked my interest to move into 3D printing research, and so I applied for PhD at the University at Buffalo, New York.At the time, the lab that I joined just started tissue engineering work. Combining 3D printing with tissue engineering, we then started bioprinting research there. After completing my PhD, I joined The University of Iowa as an assistant professor, where I established my independent lab and started my career as an independent researcher. We began working on various aspects of bioprinting, developing innovations there including co-axial bioprinting technology which has been translated into the market now. Then in 2015, I joined The Pennsylvania State University.You recently created a 3D-printed breast cancer tumor model. Could you tell us a bit more about this?One of the application areas of bioprinting technologies in our lab is building 3D tissue models, such as cancer. Our primary area of interest lies in breast cancer and understanding how the ca
这就是为什么我们一直在开发这些3D模型。美国国立卫生研究院最近授予你一笔资金,用于开发加速骨骼、气管和器官生物打印过程的技术。你能详细介绍一下吗?这是我们自2017/18年以来一直在做的事情。我们花时间了解了该技术的基本原理,重点是组织球体的3D生物可打印性[3,4]。目前,生物打印界的大多数研究人员使用生物墨水,其中细胞主要装载在水凝胶中,这有一些局限性。一个是原生组织有很高的细胞密度,如果你用充满细胞的水凝胶很难模仿。这就是为什么我们有时使用无支架,无水凝胶的系统,我们将细胞压缩成三维聚集体,称为球体,利用它们作为构建块。然后我们把它们一个接一个地打印出来,让它们自我组装成一个更大的组织结构。目前,在该领域的所有可用技术中,这个过程的主要问题是这些球体是单独打印的。所以,这个过程非常缓慢,需要很长时间才能创造出可扩展的东西。为了解决这个问题,我们开发了一种技术,可以大大加快这一过程。所以,不用等几天,你可以在一小时内完成结构。我们可以用这项技术制造气管和骨头。您如何设想3D打印在临床环境中的应用?在世界各地,有各种正在进行的临床试验,探索在临床环境中使用生物打印组织。总部位于纽约的一家名为3DBio Therapeutics的公司进行了一项临床试验,探索3d生物打印耳组织的开发和植入,以治疗耳朵生长异常的情况。这是生物打印组织临床转化的一个很好的例子。希望这些临床试验能为皮肤、软骨和骨组织等其他组织开辟新的途径。与胰腺、肺和肝脏等实体器官相比,制造这些组织相对简单,后者可能更具挑战性。好在有很多正在进行的项目,我希望在未来几年我们能看到更多的临床转化。医学生物打印领域面临的一些挑战是什么?您认为如何克服这些挑战?我们还有一些技术问题没有解决,比如血管化的整合。在血管化方面有大量的努力在进行,但是在一个复杂的3D器官结构中创建一个从动脉和静脉一直到毛细血管的血管网络仍然是一个挑战。如果在大型组织或器官中没有这种复杂的血管网络系统的适当整合,我们就无法真正制造出可扩展的实体器官。同时,为了制造这些器官,我们需要器官特异性的细胞类型。虽然我们有干细胞和原代细胞,但识别器官中存在的所有细胞类型仍然是一个挑战。例如,如果我们要制造一个胰腺,我们需要β细胞,我们可以从诱导多能干细胞中区分出来。对于α细胞和其他胰腺细胞,获得所有这些细胞并将它们整合到一个系统中更具挑战性。特定器官中缺乏所有类型的细胞,以及3d生物打印可灌注的复杂多尺度血管网络的创建仍然是未来5-10年内需要克服的技术挑战。除了技术上的挑战,我们还有与临床翻译相关的监管挑战。有时,监管过程可能需要数年时间,但好在我们现在有生物打印结构用于临床试验的例子。它们将成为监管机构的一个很好的榜样,然后有望使这一过程比过去更容易。你认为这个领域最近最有前途的创新是什么?有几个正在进行的发展,我可以说,在过去的10年里,这个领域有了显著的发展。我们已经看到了来自不同研究实验室和公司的突破性发展。例如,在包括我的团队在内的多个研究实验室的贡献下,术中生物打印技术,意味着我们可以直接在手术环境中使用3D生物打印,已经取得了显著的进步。它也被称为原位或体内生物打印。我们已经展示了各种组织、器官的术中生物打印,如骨、软骨、肌肉和皮肤,以及骨和皮肤的复合版本。这是我们(我的实验室)在该领域做出的重大贡献。 这在将3D生物打印转化为诊所方面具有很大的潜力,我们将看到手术室里有生物打印机,外科医生可以通过术中生物打印技术修复身体部位。此外,我们还看到了使用嵌入式生物打印工艺[10]打印的各种组织类型。以前,生物打印是在没有使用嵌入式生物打印的情况下进行的,我们过去常常在空气中打印结构。研究人员现在可以创造出非常复杂的形状,这在过去是不可能的。它也给我们带来了很多能力来概括这些器官的复杂形状和几何形状。你认为未来10-15年生物打印领域会发展到什么程度?这是一个经常被问到的问题。我想谈谈这个领域到目前为止是如何发展的。从2000年到2010年,我们主要可以打印细胞。当时的主要目标不是立即生成组织,而是重点放在打印细胞上,以证明生物打印是可行的。从2010年到2020年,纸巾打印技术取得了重大进展。因此,我们已经从打印细胞发展到打印不太复杂的组织,没有多尺度的血管。在接下来的10年里,我们将看到更多的进展,特别是在胰腺、肺、心脏和肾脏等实体器官方面。我们还将在3d打印实体器官的血管化和血管化整合方面看到更多的努力。我不知道能否在10年内完成,但我可以说,我们将在未来10年内在该领域取得重大进展。与此同时,在未来10年,我们将看到更多的临床试验和3d生物打印组织的转化,特别是肌肉骨骼组织。财务披露it Ozbolat承认来自美国国立卫生研究院(国家生物医学成像和生物工程研究所)的资助。除了那些披露的内容外,作者与任何组织或实体没有其他相关的从属关系或财务参与,这些组织或实体与手稿中讨论的主题或材料有经济利益或经济冲突。竞争利益披露it Ozbolat拥有Biolife4D的股权,并且是Biolife4D和Healshape的科学顾问委员会成员。除了已披露的内容外,作者与稿件中讨论的主题或材料没有其他竞争利益或与任何组织或实体的相关关系。写作披露在本手稿的制作过程中没有使用任何写作辅助。采访中表达的观点是Ibrahim T Ozbolat的观点,并不一定反映未来医学有限公司的观点。开放获取本作品在署名-非商业性-非衍生品4.0未移植许可下获得许可。要查看此许可证的副本,请访问http://creativecommons.org/licenses/by-nc-nd/4.0/References1。Dey M, Kim MH, Dogan M等。生物3D打印血管化乳腺肿瘤模型的化疗和基于CAR-T细胞的免疫治疗筛选放置功能。物质学报,32(52),2203966(2022)。Crossref, CAS,谷歌Scholar2。Dey M, Kim MH, Nagamine M等。三维乳腺癌模型的生物构建,用于解剖表达工程化MAIT细胞受体的人T细胞的细胞毒性反应。生物工程学报,2014,44(4):444 - 444(2022)。Crossref,谷歌Scholar3。闫斌,许东,张震等。用于精确定位生物制剂的吸气辅助生物打印。科学。生物工程学报,6(10),eaaw5111(2020)。Crossref, Medline, CAS,谷歌Scholar4。张志强,张志强,张志强,等。在屈服应力凝胶中,抽吸辅助的预制组织球体的自由形态生物打印。物理学报,2013,33(2020)。Crossref, Medline, CAS,谷歌Scholar5。3 dbiotherapuetics。https://3dbiocorp.com/Google Scholar6。吴毅,Ravnic DJ, Ozbolat IT。术中生物打印:在外科环境中修复组织和器官。生物技术进展,38(6),594-605(2020)。Crossref, Medline, CAS,谷歌Scholar7。Moncal KK, Aydın RST, Godzik KP等。术中生物打印骨构建物控制pPDGF-B和

Aim: This study was intended to investigate the effect of laser power ratios (LPRs) on the sinterability and sintering performance of selective laser sintering (SLS) mediated 3D prototypes. Materials & methods: Physical mixtures (PMs) containing Kollidon SR (98.75% w/w) and IR-absorbing dye (1.25% w/w) were evaluated for flow characteristics and particle size. The same PMs were subjected to SLS-mediated prototyping at constant printing temperatures (feed bed temperature 30°C and print bed temperature 40°C) over a range of LPRs. Results & conclusion: With favoured particle size and flow properties, this PMs was found to be suitable for SLS-mediated 3D printing. Sinterability and sintering performance were improved incrementally throughout the range of studied LPRs. The best sintering performance in terms of dimensional accuracy and printing yield was achieved at the highest LPR (3.0). Scanning electron microscopy (SEM) depicted topography of cross-sectioned sintered printlets.
目的:研究激光功率比(LPRs)对选择性激光烧结(SLS)介导的3D原型材料烧结性能和烧结性能的影响。材料,方法:对含Kollidon SR (98.75% w/w)和ir - absorption dye (1.25% w/w)的物理混合物(pm)的流动特性和粒径进行评价。在一定的lpr范围内,在恒定的打印温度(进料床温度30°C,打印床温度40°C)下,对相同的pm进行sls介导的原型制作。结果,结论:该材料具有良好的粒径和流动特性,适合于sls介导的3D打印。在研究的LPRs范围内,烧结性能和烧结性能逐渐提高。在最高LPR(3.0)时,烧结尺寸精度和打印良率均达到最佳。扫描电子显微镜(SEM)描绘了烧结小块的横截面形貌。

Aim: Tracheobronchial anatomy for bronchoscopy education is challenging. 3D printing (3DP) is a promising technology to design bronchoscopy simulators. Materials & m ethods: We created a 3DP tracheobronchial model and color-coded the airways to train first-year pulmonary fellows. A pre- and post-test, practical test and post-test questionnaires were used to evaluate the curriculum implementation. Results: For six fellows the pre- and post-test mean score improved from 11.5/22 (SD = ±1.71) to 16.2/22 (SD = ±2.79). Practical testing mean was 34.5/54 (SD = ±5.82). Questionnaires rated the 3DP model favorably. Conclusion: Our pilot curriculum using a color-coded 3DP model demonstrated improvement in airway identification with favorable ratings by fellows. We posit conceptual frameworks in play and how we address them in future models.

We aim to improve the residuum health of individuals suffering from lower-limb loss through ‘digital twin’ computational simulations for the creation of optimized 3D-printed prosthetic attachments. Our objective is to utilize 4D tracking data of various tissue interfaces as a primary input into the digital twin. Dynamic anatomical ultrasonography (DAU) is a novel technique in which synchronized individual transducers are positioned at known locations utilizing a 3D-printed holder. Pulse-echo ultrasound data are recorded and subsequently analyzed, providing plots of tissue interface depths versus recording time. For the scientific validation of the DAU technique, a bespoke 3D-printed phantom twin has been created incorporating replica compartments of soft-tissue interfaces and bone tissue of a healthy thigh. To demonstrate its utility, a preliminary experiment was performed in which the phantom twin was positioned within the DAU device and the replica bone manually traversed randomly; subsequent DAU analysis provided a plot of interface depth versus recording time.

3D Bioprinting has become a revolutionary tool in the field of tissue engineering and regenerative medicine. Bioprinting industry has seen a tremendous growth in the past decade, with a number of bioink companies and bioprinter companies on the rise. While the growth of bioprinting has been tremendous in terms of research and reach, permeating into life sciences research where two-dimensional cell culture has been the norm, we are yet to witness a commercial success in terms of clinical translation. This perspective article aims to highlight some of the lesser-discussed challenges in the field that are to be overcome to fully translate the use of bioprinting into the clinics and make it a standard of testing in the pharmaceuticals industry.

In oral and maxillofacial surgery (OMFS), 3D printing technology has been implemented to improve precision in treatment planning, increase surgical predictability, reduce operation times, and lower overall costs. Furthermore, 3D printing has opened access to surgical training, facilitated patient-physician relationships, and generated greater surgical outcomes. The aim of this review is to summarize the impact of 3D printing technology in the field of OMFS. We discuss its many applications in the management of maxillofacial trauma and reconstruction, orthognathic surgery, maxillofacial prosthodontics, temporomandibular joint (TMJ) reconstruction, dental implants (3D-printed surgical guides and 3D-printed dental implants), bone tissue engineering for maxillofacial regeneration, clinical education, and patient communication.

Background: Post-infarct ventricular septal defect (PIVSD) is a serious complication of myocardial infarction. We evaluated 3D-printing models in PIVSD clinical assessment and the feasibility of statistical shape modeling for morphological analysis of the defects.
Methods: Models (n = 15) reconstructed from computed tomography data were evaluated by clinicians (n = 8). Statistical shape modeling was performed on 3D meshes to calculate the mean morphological configuration of the defects.
Results: Clinicians' evaluation highlighted the models' utility in displaying defects for interventional/surgical planning, education/training and device development. However, models lack dynamic representation. Morphological analysis was feasible and revealed oval-shaped (n = 12) and complex channel-like (n = 3) defects.
Conclusion: 3D-PIVSD models can complement imaging data for teaching and procedural planning. Statistical shape modeling is feasible in this scenario.

Aim: To understand the role point-of-care 3D printing is playing in medical device innovation, to articulate tangible and intangible benefits of open social innovation models with internal and external stakeholders, and to identify key considerations to support implementation of 3D printing in public hospitals. Method: Survey on an Australian public health precinct (n = 68). Results: 3D printing influences organizational culture and how users navigate the regulatory framework. Access to on-site 3D printing technology stimulates collaboration and rapid design cycles. Open innovation approaches can help reconcile motivations, as well as social and economic benefits. Staff training, engagement with regulatory reforms and a recalibration of the scope of impact that design thinking can have on medical device innovation projects are needed.
