What do you need to prepare your facility to receive an additive machine, especially a metal additive system? Here are a few recommendations. Be sure you have the right voltage available, or devices to make the additive machines compatible with … [Read more...] about How to prepare your facility for the installation of an additive machine
In addition to the metal additive machine, other pieces are needed, many of which are often included with the additive machine. These are: A wet separator, which is really a vacuum to remove excess metal powder. It includes a water tower where … [Read more...] about What other equipment is needed with a 3D metal additive printer?
Continuous Fiber Fabrication (CFF) is a term coined by Markforged for the material and 3D printing process it developed. CFF operates in this way. The printer uses two print nozzles. One nozzle operates like a typical extrusion process; it lays … [Read more...] about What is Continuous Fiber Fabrication (CFF)?
In some 3D printing/additive manufacturing processes, the object goes under repeated expansion and contraction from the heating and cooling of the build process. This repeated heating and cooling can lead to residual stress—a result that shows up as … [Read more...] about 3D Printing Residual Stress: What Is It?
Density in additively made parts refers to the porosity of a part and is usually an issue with laser sintered additive technology. (see what is porosity) Some parts require as high a density as possible in application. Parts that must operate … [Read more...] about What does part density mean in additive manufacturing?
Porosity refers to the level of solidity achieved in an additively made metal part, that is, whether there are cavities or holes between the layers of a part. In some metal additive manufacturing processes, a laser is used to melt a layer of metal … [Read more...] about What does “porosity” mean in metal additive manufacturing?
Most of the additive manufacturing (AM) sector initially chose to work with just one specific alloy, that being the die-casting alloy AlSi10Mg. This is also considered to be equivalent to these other alloy designations: British casting alloy LM9, EN … [Read more...] about Aluminum and additive manufacturing—quick tips
Cobalt-Chromium-Molybdenum alloy, which is simply referred to as Cobalt-Chrome, is used in the dental sector. It is a derivative of the ISO 5832 alloy, or ASTM F75, that has its historical origins as a Stellite alloy, and which was originally … [Read more...] about Working with Cobalt-Chrome in additive manufacturing applications
Other high temperature superalloy compositions have been based on the Ni group alloys known as Inconel, with the two most frequent variants being 625 and 718. The choice of which alloy to use will depend on the maximum operating temperature and the … [Read more...] about Tips on working with Nickel and Nickel alloys in metal additive manufacturing
Steel powders can be sub-divided into either tool steels or stainless steels, and there has been a vast body of work carried out over the last 15 years or so to study the performance of these alloys both in the AM process and in actual … [Read more...] about What to know about working with steel materials in additive manufacturing
