AbstractThe Three-Dimensional Printing (3DP™) process has been modified to incorporate colloidal science for the fabrication of fine ceramic parts. Complex shaped alumina and silicon nitride components have been formed directly from 3-dimensional CAD files using submicron powders. Parts were built using a sequential layering process of the ceramic slurry followed by ink jet printing of a binder system. A well dispersed slurry and optimized printing parameters are required to form a uniform powder bed with a high green density. Liquid-powder bed interactions affect the geometry and internal structure of the component. The redispersion of the unprinted powder bed is critical in order to retrieve the printed components. The slurry and powder bed chemistry are the major factors controlling powder bed redispersion. The process is generic and can be readily adapted for new materials systems. Our research is currently focused on the fabrication of dielectric RF filters. Preliminary results have demonstrated the ability to successfully fabricate cylindrical RF resonators.

ABSTRACTThree Dimensional Printing is a process for rapid prototyping of functional components. Thin layers of powder are bound in selected areas by ink-jet printing of a liquid binder. Layers are added sequentially until a three dimensional part is completed. The unbound powder is then removed. The raster scan pattern and layering used in forming has an observable effect on the surface finish and microstructure of the part, as does the chemistry of the particular materials system used. Important phenomena include ballistic interaction of the jet with the powder bed and wicking of the binder. Process parameters such as layer height, flow rate, and powder density were studied. Microstructural examination of the printed components is also reported.

Three Dimensional Printing is a process for the manufacture of tooling and functional prototype parts directly from computer models. Three Dimensional Printing functions by the deposition of powdered material in layers and the selective binding of the powder by “ink-jet” printing of a binder material. Following the sequential application of layers, the unbound power is removed, resulting in a complex three-dimensional part. The process may be applied to the production of metal, ceramic, and metal-ceramic composite parts. An experiment employing continuous-jet ink-jet printing technology has produced a three-dimensional ceramic part constructed of 50 layers, each 0.005 in. thick. The powder is alumina and the binder is colloidal silica. The minimum feature size is 0.017 in., and features intended to be 0.5000 in. apart average 0.4997 in. apart in the green state and 0.5012 in. apart in the cured state, with standard deviations of 0.0005 in. and 0.0018 in., respectively. Future research will be directed toward the direct fabrication of cores and shells for metal casting, and toward the fabrication of porous ceramic preforms for metal-ceramic composite parts.

Dimensional Printing

Hydrogels possess three-dimensional polymeric network structure and equipped for retaining extensive measure of water or organic fluids. This quality makes them as exceptional candidate for the simulation of extra cellular matrixes. For this the three dimensional printing (3DP) has evolved as the technique for the formation of the digital models. The 3DP is capable for processing the prescriptions and the therapeutic gadgets. One of the technique known as stereolithographic (SLA) printing has shown promising results in formulating the hydrogel based system for fabrication. The SLA acts by cross connecting the saps to shape the polymer matrices. Due to water captured in the gels it is conceivable to create the pre- wetted, medicate hydrogels and gadgets. The 3DP helps in formation of tailor made drug delivery system as per needs of patients. Many of Bioinks has been tried up for the hydrogel formation such as collagen, gelatin, hyaluronan, silk, alginate, and nanocellulose etc. Keywords: 3D Printing, Hydrogel, Steriolithography

Background: The emerging Three-dimensional (3D) modelling improves intraoperative visualization, management, and analysis of available imaging data, the 3D form of available image, provides the surgeon with a better comprehension of the geometry, size, and exact relationship between target and normal tissue. The role of 3D modelling in orthopedic pelvic and hip surgical planning is brought to focus.Methods: The Medline database was searched using the keywords 3D printing, three dimensional printing, 3 dimensional printing and the results were screened for pelvis and hip surgery related full text articles. The duplicates and non-related articles were removed.Results: The articles were used to build a review with focus on Acetabulum, Pelvis, Hip and sacrum. We found that the role of 3D printing is non-negligible. The advances made with the help of 3D printing are wonderful and promising. The use of 3D saw its application in many fields. But the orthopedic surgery to our observance has benefitted the most till now.Conclusions: With the advances in the technology it is needed to make the 3D modelling easier, quicker, accurate, cost effective and reliable to help implement its deeper use in orthopedics. The authors believe that the 3D printing is an enormous help for the orthopedic surgeons which will only lead to positive outcomes.

Cardiovascular 3-dimensional printing refers to the fabrication of patients’ specific cardiac anatomic replicas based on volumetric imaging data sets obtained by echocardiography, computed tomography, or magnetic resonance imaging. It enables advanced visualization and enhanced anatomic and sometimes hemodynamic understanding and also improves procedural planning and allows interventional simulation. Also, it is helpful in communication with patients and trainees. These key advantages have led to its broad use in the field of cardiology ranging from congenital to vascular and valvular disease, particularly in structural heart interventions, where many emerging technologies are being developed and tested. This review summarizes the process of 3-dimensional printing and the workflow from imaging acquisition to model generation and discusses the cardiac applications of 3-dimensional printing focusing on its use in percutaneous structural interventions, where procedural planning now commonly relies on 3-dimensional printed models.
