Comparing Open-Source and Low-cost 3D Printers with Commercial Products

When the typewriter was introduced in 1868, it was to people what virtual reality is to us now. It was something people had never seen before, a new idea that added value and made things a little more perfect. The typewriter created perfect typography, but one mistake meant the paper had to be re-written. The same is true today as more and more people learn how to use 3D printing and rapid prototyping. One over-looked mistake in the design of a piece can be fatal to a budget or to the project itself. For that reason, in this article we will discuss the implications and differences between open-source low-cost 3D printers, and commercial rapid prototyping machines. Open-Source Low-Cost 3D Printers Open-Source is the term given to software that is free to use and be edited by people other than the creator. This made a shift in the way that creators and 3D enthusiasts create objects. Imagine if the software was not open-sourced, what would happen? People would have to create and design their own 3D …

Binding of Granular Materials and Techniques

3D printing has greatly revolutionized the printing process since its introduction in the late 70’s. The technology has made it possible for 3D companies to create low cost prototypes and specialized components for various industrial and specialized needs. The granular binding process involves fusing different layers of granules in a repeat process in order to build a desired object. In most part, the sintering process that helps create solid media is often done using a laser beam and support systems. On the other hand, although the vast majority of 3D printing is carried out using molten plastic; one branch of 3D printing that is growing fast is the one that involves metal fabrication and forging. Good examples of these additive metal manufacturing processes include Selective Laser Melting (SLM), Electron Beam Melting (EBM) and Direct Metal Laser Sintering (DMLS). Speaking in the same breadth, it is important to recognize that metal printing techniques are slightly different from plastic printing technologies. a) Direct Metal Laser Sintering (DMLS) DMLS is an efficient, additive making process with a huge …
