With Hard Work, Incredible Patience and Wits, Professor Builds Ceramic 3D Printer from a Simple Delta Kit

Bound Metal Additive Manufacturing Market Outlook – Metal Binder Jetting and Bound Metal Deposition Taekyeom received some advice on his clay extruder and an engineer said, PVC pipe is not a safe material because PVC can crack, or even shatter. Cooper or stainless steel will be good material. DO NOT use PVC piping system for use in compressed air.   3D printed ceramics are a relatively less-talked-about material in the industry, compared to plastics and metals, for example. But the medium is beginning to develop and become more commonly seen, despite a lot of difficulties inherent in printing ceramic materials. For the most part, clay and ceramic printers tend to be on the industrial, large-scale side of things, with a few exceptions; the complications of the materials mean that they don’t lend themselves particularly well to casual desktop printing. That makes the ceramic 3D printer that Taekyeom Lee built even more impressive. Lee, an Assistant Professor of Graphic Design at Appalachian State University, isn’t a traditional sculptor, but his research led him to explore the material and its potential for the development of new fabrication techniques. “My research explores unco...

Understanding the ‘Science’ of Color : Plastics Technology

And as with all sciences, there are fundamentals that must be considered to do color right. Here’s a helpful start. When enumerating the advantages of using plastics over other materials such as metals, ceramics, and wood, one of the items that inevitably comes up is molded-in color. Even in industries like automotive that still rely on painting plastics, the long-term objective is to achieve the desired finish and durability with molded-in color. The plastics industry has touted this advantage for such a long time that we frequently do not consider the intricacies and potential problems that can arise when incorporating color into a polymer. But there is a science to this process; and as with all sciences, there are fundamentals that must be observed if things are to work properly. In this article we will briefly review these fundamentals and discuss the things that we observe when we fail to adhere to them. There are several key items that are essential in developing a colorant package for any polymer. The first of these is the avoidance of any chemical incompatibility between the chemistry of the polymer and the chemistry of the colorant system. Chemical reactions proceed mo...
