Damas December 2019 Accepted by: Dr. Cameron J. Turner, Committee Chair Dr. Gang Li Dr. Suyi Li ABSTRACT Additive manufacturing methods are becoming more prominent in the world of design and manufacturing due to their reduction of material waste versus traditional machining methods such as milling. As their demand rises, a need to improve their methodologies and produce higher quality products arises. The technology to 3D print has been in around since the 1970’s, and thanks to Scott Crump as of 1989, it is possible to 3D print in layers to obtain a solid component. In today’s present time, we now can multi- material 3D print. However, even though we have the technology for multi-material 3D printing, standards in this field are severely lacking.

  • 3D PRINTING Introduction Additive Manufacturing Or 3D Printing Is a Process of Making Three Dimensional Solid Objects from a Digital Model
    3D PRINTING Introduction Additive manufacturing or 3D printing is a process of making three dimensional solid objects from a digital model. 3D printing is achieved using additive processes, where an object is created by laying down successive layers of material. 3D printing is considered distinct from traditional machining techniques (subtractive processes) which mostly rely on the removal of material by drilling, cutting etc. A 3D Printer A hyperboloid object print (made of PLA) using a RepRap “Prusa Mendel” 3D printer for molten polymer deposition. 3D printing is usually performed by a materials printer using digital technology. Since the start of the twenty-first century there has been a large growth in the sales of these machines, and their price dropped substantially. The technology is used in the fields of jewellery, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many others. History Early examples of 3D printing occurred in the 1980s, though the printers then were large, expensive and highly limited in what they could produce. • The term "3D printing" was coined at MIT in 1995 when then graduate students Jim Bredt and Tim Anderson modified an inkjet printer to extrude a binding solution onto a bed of powder, rather than ink onto paper. The ensuing patent led to the creation of modern 3D printing companies Z Corporation (founded by Bredt and Anderson) and ExOne. • SLS was developed and patented by Dr. Carl Deckard at the University of Texas at Austin in the mid-1980s, under sponsorship of DARPA.

  • Der CAMSIZER XT
    Creative Optimization with Additive Manufacturing Webinar - Additive Manufacturing with Particle Size and Shape Analysis Many Additive Manufacturing (also called 3D printing) techniques such as selective laser sintering (SLS), selective laser melting (SLM) and electro-beam melting (EBM) use metal particle powders as a raw material (Aluminum, Titanium, Steel, Nickel, Tungsten and many Alloys). The particle size, size distribution and shape have a strong effect on the manufacturing result. Therefore it is important for manufacturers and suppliers to control the particle size and shape of their powders used in this process. In order to control particle size and shape these parameters must be measured. We discuss how to use the CAMSIZER technology to improve additive manufacturing results by monitoring the incoming particles.

    Bafna et al., International Journal of Advanced Engineering Research and Studies E-ISSN2249–8974 Proceedings of BITCON-2015 Innovations For National Development National Conference on : Information Technology Empowering Digital India Review Article 3D PRINTING: ENDLESS OPPORTUNITIES 1Harsh Bafna, 2Prof. Sarang Pitale Address for Correspondence 1Director, Ingenious Technosys, 36/B 2nd floor, New Civic Centre, Bhilai (C.G.) 2Asst. Professor, Bhilai Institute of Technology, Durg (C.G.) ABSTRACT 3D printing (or additive manufacturing, AM) is any of various processes used to make a three-dimensional object. In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot. 3D printing in the term's original sense refers to processes that sequentially deposit material onto a powder bed with inkjet printer heads. More recently the meaning of the term has expanded to encompass a wider variety of techniques such as extrusion and sintering based processes. Technical standards generally use the term additive manufacturing for this broader sense. KEY WORDS: 3D, Printing. 1. INTRODUCTION In 1993, Massachusetts Institute of Technology 3D printing is a form of additive manufacturing (MIT) patented another technology, named "3 technology where a three dimensional object is Dimensional Printing techniques", which is similar to created by laying down successive layers of material. the inkjet technology used in 2D Printers. It is also known as rapid prototyping, is a mechanized In 1996, three major products, "Genisys" from method whereby 3D objects are quickly made on a Stratasys, "Actua 2100" from 3D Systems and reasonably sized machine connected to a computer "Z402" from Z Corporation, were introduced.
