What is extrusion in 3D printing? According to the ASTM International standards organization, extrusion is the official name given to a specific 3D printing process where material is selectively dispensed through a nozzle or orifice. Extrusion is … [Read more...]
How is resolution defined in 3D printing?
Resolution is one way of measuring the print quality of a 3D printer. Unfortunately, there is no standard that all 3D printer manufacturers adhere to. Each tends to explain resolution using different parameters. Because 3D printers print in three … [Read more...]

To support or not to support in 3D printing
If you are designing a geometrically complex part for a powder bed additive manufacturing process, you probably won’t need to design in supports as well, right? That’s sort of the accepted view when designing for 3D printing / additive … [Read more...]
Master Class: How to use 3D printing for injection molds
While not the most glamorous or "sexy" application for 3D printing, using this technology to obtain molds for injection molding is one of the key applications of this technology. Tom Charron, vice president at 3D Systems, discusses the materials … [Read more...]
Electron Beam Melting: What Is It?
Electron beam melting (EBM) is a type of additive manufacturing technique that uses a cathode ray as its heat source. EBM is a proprietary powder bed fusion technique developed by Arcam. Metal powder is melted in a high vacuum, layer by layer until … [Read more...]
What is direct metal sintering?
Direct Metal Sintering is a name coined by 3D Systems to describe a process similar to Direct Metal Laser Sintering. 3D Systems’ printers, like other metal laser sintering printers, create pure, fully dense metal parts with EN ISO (fine) machining … [Read more...]
What is DMLS (Direct Metal Laser Sintering)?
Direct Metal Laser Sintering (DMLS) is an additive manufacturing process specifically using metals as the material. Most alloys can be used in the DMLS process but 17-4 Precipitation Hardened (PH) and 15-5 PH stainless steel are the most common. The … [Read more...]
What is Laser Sintering?
Selective Laser Sintering (SLS) is a type of additive manufacturing process that uses a laser as a thermal source for fusing ceramic, glass, plastic, metal powder and others into a 3-dimensional object. Many consider SLS to have the most diverse list … [Read more...]
