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...] about What is extrusion in 3D printing?
3D Printing Basics
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...] about How is resolution defined in 3D printing?
The Additive Manufacturing Users Group (AMUG) today announced that it is accepting applications for two scholarships for additive manufacturing and 3D printing education and professional development at its annual conference. The scholarships have … [Read more...] about Additive manufacturing users group accepting scholarship applications
Students worldwide: This season’s Extreme Redesign 3D Printing Challenge will open on September 2 for entries. Read the contest rules to get started. Since the contest’s inception 12 years ago, Stratasys has awarded more than $130,000 in scholarships … [Read more...] about Two weeks left to enter extreme redesign 3D printing challenge
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...] about To support or not to support in 3D printing
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...] about Master Class: How to use 3D printing for injection molds
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...] about Electron Beam Melting: What Is It?
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...] about What is direct metal 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...] about What is DMLS (Direct Metal 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...] about What is Laser Sintering?
