Electron beam melting (EBM) is an additive manufacturing technology that uses an electron beam instead of a laser as its heat source to melt metal materials. (It does not work with thermoplastic polymer materials.) Basically, electrical charge … [Read more...] about Which vendors make electron beam additive manufacturing systems?
Material Jetting is one of the processes available to build parts in an additive format. Material jetting 3D printers use a printhead that is similar to those found in paper inkjet printers, except that these printheads deposit droplets of material … [Read more...] about Which vendors make jetting 3D printing systems
Many industries, including automotive, aerospace, and robotics are using additive parts made of carbon fiber. These parts are popular for the strength-to-volume ratio they offer. But the use of carbon in additive materials may not always produce a … [Read more...] about How to get good feature detail with 3D printed carbon fiber parts
Among the ways to deposit material in a layer-by-layer approach, one is to use jetting technology. Jetting material in this manner is akin to inkjet printing. But, instead of ink as the material, the material is usually a type of photopolymer or wax. … [Read more...] about What is polyjet 3D printing?
In most additive layer processes, the build direction is usually the Z axis. However, orienting a part to this axis may affect build time, part strength, and even total build cost. Let’s look at a typical powder-bed additive process. A heat source … [Read more...] about Additive design tips—A look at the importance of orientation
Plastic materials were the first to be 3D printed. But for many users, the ability to print in metal material is key. The use of metal materials in a 3D printer or additive machine has challenges, though. The primary one being that many metals are … [Read more...] about Which vendors make additive systems for metal materials?
One of the earliest and most common methods of making parts one layer at a time is extrusion, also known as Fused Deposition Modeling (FDM, trademarked by Stratasys) and Fused Filament Fabrication (FFF). In extrusion, material is extruded through one … [Read more...] about Which vendors make extrusion 3D printers?
As of this writing, and in alphabetic order, these companies offer 3D printing/additive systems that use stereolithography, or a version of stereolithography, to build parts layer by layer. You may find a number of companies making stereolithography … [Read more...] about Which vendors make stereolithography 3D printers?
Additive manufacturing (aka 3D printing) predominantly consists of build techniques that use a layer by layer approach. A number of factors are important to make the most out of designing for this technology. Here are six to consider. 1. Part … [Read more...] about What are important design tips for 3D printing?
Continuous Fiber Fabrication (CFF) is a term coined by Markforged for the material and 3D printing process it developed. In CFF a printer uses two print nozzles to deposit printing material. One nozzle operates like a typical extrusion … [Read more...] about What properties does continuous fiber give 3D printed materials?
