applications of 3D Printing in cardiovascular diseases
Nature Reviews Cardiology, 2016Co-Authors: Andreas A Giannopoulos, Dimitrios Mitsouras, Shi Joon Yoo, Peter P. Liu, Yiannis S. Chatzizisis, Frank J. RybickiAbstract:3D Printing applications for cardiovascular care range from models for education to planning and simulation of interventions and the generation of implantable devices. This Review summarizes the current cardiovascular 3D Printing strategies and applications, including the workflow from image acquisition to the generation of a hand-held model, and highlights the future perspectives of cardiovascular 3D Printing. 3D-printed models fabricated from CT, MRI, or echocardiography data provide the advantage of haptic feedback, direct manipulation, and enhanced understanding of cardiovascular anatomy and underlying pathologies. Reported applications of cardiovascular 3D Printing span from diagnostic assistance and optimization of management algorithms in complex cardiovascular diseases, to planning and simulating surgical and interventional procedures. The technology has been used in practically the entire range of structural, valvular, and congenital heart diseases, and the added-value of 3D Printing is established. Patient-specific implants and custom-made devices can be designed, produced, and tested, thus opening new horizons in personalized patient care and cardiovascular research. Physicians and trainees can better elucidate anatomical abnormalities with the use of 3D-printed models, and communication with patients is markedly improved. Cardiovascular 3D bioPrinting and molecular 3D Printing, although currently not translated into clinical practice, hold revolutionary potential. 3D Printing is expected to have a broad influence in cardiovascular care, and will prove pivotal for the future generation of cardiovascular imagers and care providers. In this Review, we summarize the cardiovascular 3D Printing workflow, from image acquisition to the generation of a hand-held model, and discuss the cardiovascular applications and the current status and future perspectives of cardiovascular 3D Printing.

Medical 3D Printing for the Radiologist
RadioGraphics, 2015Co-Authors: Amir Imanzadeh, Peter C. Liacouras, Edward J. Caterson, Elizabeth George, Nicole Wake, Dimitrios Mitsouras, Kanako K. Kumamaru, Andreas A Giannopoulos, Bohdan PomahacAbstract:While use of advanced visualization in radiology is instrumental in diagnosis and communication with referring clinicians, there is an unmet need to render Digital Imaging and Communications in Medicine (DICOM) images as three-dimensional (3D) printed models capable of providing both tactile feedback and tangible depth information about anatomic and pathologic states. Three-dimensional printed models, already entrenched in the nonmedical sciences, are rapidly being embraced in medicine as well as in the lay community. Incorporating 3D Printing from images generated and interpreted by radiologists presents particular challenges, including training, materials and equipment, and guidelines. The overall costs of a 3D Printing laboratory must be balanced by the clinical benefits. It is expected that the number of 3D-printed models generated from DICOM images for planning interventions and fabricating implants will grow exponentially. Radiologists should at a minimum be familiar with 3D Printing as it relates to their field, including types of 3D Printing technologies and materials used to create 3D-printed anatomic models, published applications of models to date, and clinical benefits in radiology.

Innovations in 3D Printing: a 3D overview from optics to organs.
The British journal of ophthalmology, 2014Co-Authors: Carl Schubert, Mark C Van Langeveld, Larry A DonosoAbstract:3D Printing is a method of manufacturing in which materials, such as plastic or metal, are deposited onto one another in layers to produce a three dimensional object, such as a pair of eye glasses or other 3D objects. This process contrasts with traditional ink-based printers which produce a two dimensional object (ink on paper). To date, 3D Printing has primarily been used in engineering to create engineering prototypes. However, recent advances in Printing materials have now enabled 3D printers to make objects that are comparable with traditionally manufactured items. In contrast with conventional printers, 3D Printing has the potential to enable mass customisation of goods on a large scale and has relevance in medicine including ophthalmology. 3D Printing has already been proved viable in several medical applications including the manufacture of eyeglasses, custom prosthetic devices and dental implants. In this review, we discuss the potential for 3D Printing to revolutionise manufacturing in the same way as the Printing press revolutionised conventional Printing. The applications and limitations of 3D Printing are discussed; the production process is demonstrated by producing a set of eyeglass frames from 3D blueprints.

two dimensional 2d slices encryption based security solution for three dimensional 3D Printing industry
Electronics, 2018Co-Authors: Giao N Pham, Sukhwan Lee, Ohheum Kwon, Kiryong KwonAbstract:Nowadays, three-dimensional (3D) Printing technology is applied to many areas of life and changes the world based on the creation of complex structures and shapes that were not feasible in the past. But, the data of 3D Printing is often attacked in the storage and transmission processes. Therefore, 3D Printing must be ensured security in the manufacturing process, especially the data of 3D Printing to prevent attacks from hackers. This paper presents a security solution for 3D Printing based on two-dimensional (2D) slices encryption. The 2D slices of 3D Printing data is encrypted in the frequency domain or in the spatial domain by the secret key to generate the encrypted data of 3D Printing. We implemented the proposed solution in both the frequency domain based on the Discrete Cosine Transform and the spatial domain based on geometric transform. The entire 2D slices of 3D Printing data is altered and secured after the encryption process. The proposed solution is responsive to the security requirements for the secured storage and transmission. Experimental results also verified that the proposed solution is effective to 3D Printing data and is independent on the format of 3D Printing models. When compared to the conventional works, the security and performance of the proposed solution is also better.

interpolating spline curve based perceptual encryption for 3D Printing models
Applied Sciences, 2018Co-Authors: Giao N Pham, Sukhwan Lee, Kiryong KwonAbstract:With the development of 3D Printing technology, 3D Printing has recently been applied to many areas of life including healthcare and the automotive industry. Due to the benefit of 3D Printing, 3D Printing models are often attacked by hackers and distributed without agreement from the original providers. Furthermore, certain special models and anti-weapon models in 3D Printing must be protected against unauthorized users. Therefore, in order to prevent attacks and illegal copying and to ensure that all access is authorized, 3D Printing models should be encrypted before being transmitted and stored. A novel perceptual encryption algorithm for 3D Printing models for secure storage and transmission is presented in this paper. A facet of 3D Printing model is extracted to interpolate a spline curve of degree 2 in three-dimensional space that is determined by three control points, the curvature coefficients of degree 2, and an interpolating vector. Three control points, the curvature coefficients, and interpolating vector of the spline curve of degree 2 are encrypted by a secret key. The encrypted features of the spline curve are then used to obtain the encrypted 3D Printing model by inverse interpolation and geometric distortion. The results of experiments and evaluations prove that the entire 3D triangle model is altered and deformed after the perceptual encryption process. The proposed algorithm is responsive to the various formats of 3D Printing models. The results of the perceptual encryption process is superior to those of previous methods. The proposed algorithm also provides a better method and more security than previous methods.

Fundamentals and applications of 3D Printing for novel materials
Applied Materials Today, 2017Co-Authors: Jian Yuan Lee, Chun Kiang Chua, Jia An, Chee Kai ChuaAbstract:Abstract 3D Printing is emerging as an enabling technology for a wide range of new applications. From fundamentals point of view, the available materials, fabrication speed, and resolution of 3D Printing processes must be considered for each specific application. This review provides a basic understanding of fundamentals of 3D Printing processes and the recent development of novel 3D Printing materials such as smart materials, ceramic materials, electronic materials, biomaterials and composites. It should be noted that the versatility of 3D Printing materials comes from the variety of 3D Printing systems, and all the new printers or processes for novel materials have not gone beyond the seven categories defined in ISO/ASTM standard. However, 3D Printing should never be seen as a standalone process, it is becoming an integral part of a multi-process system or an integrated process of multiple systems to match the development of novel materials and new requirements of products.
