Mimaki 3D打印将全面的现实主义和准确性带入解剖模型

The capabilities of a 3DUJ-553 3D printer frommimaki,一家宽格式喷墨打印机和切割机的制造商,已由佛罗伦萨大学和Mimaki的独家意大利进口商Bompan生产具有先前无法实现的颜色保真度的3D打印解剖模型。

During the project, a team of visionary doctors and researchers came together to realize the full color and photorealism capabilities of Mimaki’s 3D printing technology, which they believe could mark a turning point in anatomical models and the teaching of knowledge around the human body.

After creating and patenting a unique image implementation and integration algorithm to generate precise graphic reproductions of anatomical systems, the researchers turned to Mimaki’s 3DUJ-553 to print the first model, a heart, with good dimensions, detail definition, and “excellent” color fidelity.

这台工业尺寸的机器基于公司的UV喷墨技术,该技术将传统的喷墨印刷头与经济的UV LED光源相结合。打印机通过喷射连续的墨水层来工作,这些墨水可立即固化以构建完整的3D对象。

The 3DUJ-553 has previously been utilized tosupport the development of engaging exhibits并在公共计划中生产3D印刷模型史密森尼展览Landover的工作室。该机器也已在游戏领域部署到3D打印复杂的模型竞赛的获胜设计我的世界,由瑞典开发人员创建的流行的沙盒视频游戏Mojang

自3DUJ-553推出以来,Mimaki已经确定了市场上较小的入门级机器的需求,价格更便宜。该公司随后启动了full color desktop-sized 3DUJ-2207 3D printerin November last year, which is commercially available for less than €40,000.

3D打印在解剖学研究中的作用

For centuries, anatomy has been the basis of medical and scientific knowledge, and remains a vital tool in the training and professional development of doctors around the world. Producing realistic and accurate representations of the morphology of the human body is therefore vital in the teaching of anatomical knowledge, and this is where the benefits of 3D printing technologies can play a key role.

The main method of anatomical investigation is still currently dissection, which allows researchers to gain knowledge and produce an iconographic representation of the structures of the human body. However, due to issues such as the perishable nature of corpses and legal complications, this method has become increasingly less practical.

因此,佛罗伦萨大学的医师和副教授费迪南多·帕特诺斯特罗(Ferdinando Paternostro)和贾科莫·盖拉蒂(Giacomo Gelati)医生开始寻找新的方法来填补解剖学研究中现有的空白。

Gelati说:“在我的医学研究中,感谢我的教授Ferdinando,我对解剖结构充满热情。”“但是,我很快就意识到了一系列困难。不仅不可能参加解剖解剖学练习课程,而且使用的肖像学(尽管基于照片,尽管照片显示了逼真的解剖学细节和具有巨大艺术价值的水彩,尽管依靠解剖结构的示意图)仍然是平坦的,但仍然是平坦而静态的。因此不是很有用。

“对于研究解剖学或练习医学的人来说,有机会看到解剖标本的真实光和颜色,并测试其与周围结构的一致性和关系,这确实可以有所作为。”

利用Mimaki的3D打印技术

为了解决这个问题,Gelati创建并为产生解剖系统的精确图形复制的独特图像实现和集成算法创建了专利。一旦实现了这一目标,医生就希望将3D打印栩栩如生。

“We had beautiful and effective graphic images available, so we began to consider the opportunity to transform them into 3D, manageable and imperishable objects,” continued Gelati. “We immediately thought about 3D printing, focusing on color fidelity, which is a crucial element for us.”

The researchers turned to Bompan and Mimaki’s 3D printing technology to produce the models, with the technology chosen specifically for its full color capabilities.

盖拉蒂说:“这是挑战的挑战。”“图形质量和打印质量齐头并进:如果没有一个好的源文件,就永远不会有一个好的3D打印对象,相反,如果没有良好的3D打印,源文件将在打印过程中失去质量。这就是为什么我们决定与一家出色的3D彩色印刷公司合作的原因。”

佛罗伦萨大学的研究人员和Bompanworked together to 3D print the first organ model – a heart – using Mimaki’s 3DUJ-553 3D printer. The pilot project proved a success, enabling the creation of a 3D heart model with good dimensions, detail definition, and excellent color fidelity. The ability to reproduce the color quality of the graphic images was the most important factor in the researchers’ choice of technology, according to Paternostro.

他解释说:“进行手术或解剖室时遇到的各种解剖结构具有自己的特定颜色,并被各种不同颜色的地形环境所包围。”“在解剖形态上区分结构并不是特别容易,颜色起着至关重要的作用。”

As such, the team’s goal is to fully leverage the color quality, replicability, and durability of 3D printed objects within medical practice, to aid the recognition of structures during surgical and anatomical dissections.

“我们让结合算法wi的对象th Mimaki’s 3D printing technology are chromatically and morphologically realistic, measurable, repeatable,” Paternostro added. “Using this method, we could potentially cross further frontiers. In pathological anatomy, for example, we will be able to create a 3D organ that shows the anomalies caused by a specific disease – thus providing a very useful tool for preparing any surgical intervention and for communicating with the patient.”

据佛罗伦萨大学的团队称,鉴于结果取得了成果,3D印刷可以有效地改变教学和医学科学研究的世界。通过Mimaki的照片。

改造医学科学研究

安德里亚·费兰特(Andrea Ferrante), 3D printing specialist, at Bompan believes the project demonstrates the superior qualities of Mimaki’s 3D printing technology and its capability to achieve the color fidelity and ultra-realistic definition of details required for anatomical models, commenting: “We are convinced that this technology will be widely used in a variety of different fields and the opportunities will be boosted by the imminent arrival of the 3DUJ-2207 – a version with a more compact and more accessible design but equipped with the same technology as the 3DUJ-553.”

根据Paternostro的说法,3D打印通常有可能在未来的教学,教育和医学科学研究的转变中进行大量帮助。

他说:“我们仍处于早期阶段,但我们有信心我们走上了正确的道路。”“我们有机会替换解剖模型并覆盖解剖学部分,包括巨大的价值,但可易腐的,因此只能在某些情况下可用 - 使用3D打印的解剖作品,可供大学,研究机构,医院和诊所使用。

“A beautiful anatomical model is functional to learning, communication, medical and surgical practice.”
