Multi Jet Fusion begins with a layer of powdered material applied from top-to-bottom on the build platform. The machine applies droplets of fusing and detailing agents along with thermal energy across the powdered material from left to right to fuse … [Read more...]
FAQs
What is a voxel in 3D printing?
New words, or words with new definitions, pop up regularly in the 3D printing industry. One of the latest words is Voxel. According to Wikipedia, "a voxel represents a value on a regular grid in three-dimensional space. These values are frequently … [Read more...]
Which is better–filament or pellet 3D printing materials?
It depends on the 3D printing system you are working with. A 3D printing vendor may opt for the filament fed approach because it helps keep the total cost of the printer low. But filament feeds tend to be slow, which affects productivity. Thermal … [Read more...]
What is the difference between the STL and 3MF formats for 3D printers?
STL (STereoLithography or Standard Tessellation Language ) was first developed to translate CAD data into data suitable for use by a stereolithography 3D printer. In the years since it’s introduction it has been used by a number of 3D printing … [Read more...]
How to prepare your facility for the installation of an additive machine
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...]
What other equipment is needed with a 3D metal additive printer?
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...]
What is Continuous Fiber Fabrication (CFF)?
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...]
3D Printing Residual Stress: What Is It?
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...]
What does part density mean in additive manufacturing?
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...]
What does “porosity” mean in metal 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...]
