Three Dimensional Printing: Rapid Tooling and Prototypes Directly from a CAD Model
Journal of Engineering for Industry, 1992Co-Authors: Emmanuel M. Sachs, Michael J. Cima, Paul Williams, David Brancazio, J. CornieAbstract: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.

Three-Dimensional Printing: Rapid Tooling and Prototypes Directly from a CAD Model
CIRP Annals - Manufacturing Technology, 1990Co-Authors: Emanuel Sachs, Michael Cima, J. CornieAbstract: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 powder 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 part comprising eight intersecting planes spaced 0.375 inches apart.

Process Capability Study of Rapid Casting Solution for Aluminium Alloys using Three Dimensional Printing
International Journal of Automotive and Mechanical Engineering, 2011Co-Authors: Rupinder SinghAbstract:In the present work best shell wall thickness of mould cavity has been investigated for process capability study of rapid casting solution for aluminum alloys using Three Dimensional Printing (3DP). Starting from the identification of component/ benchmark, aluminum-alloy casting prototype was produced at different shell wall thickness with Three Dimensional Printing. The results of the study suggests that at best shell wall thickness (5mm) for aluminum alloys, rapid casting solution using 3DP process lies in ±3.999 sigma (@) limit.

Comparison of Statistically Controlled Rapid Casting Solutions of Zinc Alloys using Three Dimensional Printing
International Journal of Automotive and Mechanical Engineering, 2011Co-Authors: Rupinder SinghAbstract:In the present work, the most cost effective/best shell wall thickness of mould cavities has been compared with other available shell wall thicknesses for statistically controlled rapid casting solutions of zinc alloy. Starting from the identification of component/ benchmark, technological prototypes were produced at different shell thicknesses with Three Dimensional Printing. The results of the study suggest that at the best shell wall thickness (7 mm) for zinc alloys, the rapid casting solution is statistically controlled, which is not observed for all shell wall thicknesses of mould cavities prepared with Three Dimensional Printing.

An overview of Three Dimensional Printing for casting applications
International Journal of Precision Technology, 2011Co-Authors: Rupinder SinghAbstract:Rapid prototyping (RP) has been in evidence for the past 20 years and is being widely used in diverse areas, from the building of aesthetic and functional prototypes to the production of tools and moulds for technological prototypes. Among various RP techniques, Three Dimensional Printing (3DP) is a relatively new form of RP. The present research paper provides an overview of RP process and specifically 3DP for shell patterns obtained from ceramic shells that can be built and then joined (as in the conventional process) to obtain the cavity for pouring metal for generation of cost effective prototypes for casting applications.

Three Dimensional Printing for Casting Applications: A State of Art Review and Future Perspectives
Advanced Materials Research, 2009Co-Authors: Rupinder SinghAbstract:Rapid prototyping (RP) is being widely used in diverse areas, from the building of aesthetic and functional prototypes to the production of tools and moulds for prototypes. Many RP techniques like stereo lithography, laminated object manufacturing, Three Dimensional Printing etc. are commercially available. The implication of these technologies revealed that the time and cost of developing new foundry tools could be greatly reduced. The purpose of the present research paper is to review Three Dimensional Printing for generation of prototype for casting applications.

Applications of Three-Dimensional Printing in Orthopaedic Surgery.
Instructional course lectures, 2018Co-Authors: Paul A. Anderson, Wellington K. Hsu, S. Raymond Golish, Adam E. Jakus, William M. MihalkoAbstract:Orthopaedic surgeons should be aware of the variety of applications of Three-Dimensional Printing, which range from rough-and-ready applications, such as rapid prototyping of implant designs with the use of polymers to the fabrication of patient-specific implants and custom implants with the use of the principles of metallurgy. The local manufacture of low-cost prosthetic devices in third-world nations is the best example of the potential application of Three-Dimensional Printing. Orthopaedic surgeons should understand the multiple applications of Three-Dimensional Printing, including prototyping of anatomy, implants, orthotics, patient-specific instrumentation, and implants that incorporate porous structures and accommodate complex anatomy, as well as the future of biologically active Three-Dimensional Printing. It is helpful to be aware of the types of Three-Dimensional Printing that are currently used in the clinical setting, those that are commercially available, and those under development.

Three-Dimensional Printing and Tissue Engineering in Orthopaedics.
Instructional course lectures, 2018Co-Authors: Adam E. Jakus, Paul A. Anderson, Wellington K. Hsu, Golish, William M. MihalkoAbstract:Additive manufacturing and Three-Dimensional Printing technology may revolutionize tissue-engineering strategies. Many clinical needs, including multitissue regeneration, remain unmet among patients with orthopaedic conditions. Ongoing research efforts in Three-Dimensional Printing, including cell-containing bioinks for bioPrinting, have resulted in acellular and cellular biomaterials that may help regenerate or replace damaged or missing biologic tissues. Recent advances in additive manufacturing aid in the preservation of biologic activity, such as the retention of growth factors, which may affect the delivery of safe, cost-effective, and efficacious bone graft substitutes for orthopaedic patients.
