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?
A DLP 3D printer is used in the additive manufacturing process where objects are created by a 3D printer that uses a digital light projector (DLP) as the light source for curing photo-reactive polymers. There are advantages and disadvantages to a DLP … [Read more...] about What is a DLP 3D Printer?
The term Fused Filament Fabrication or FFF was created by members of the Reprap project to avoid litigation over the previously trademarked term Fused Deposition Modeling coined by Stratasys, LTD. Both terms describe a nearly identical additive … [Read more...] about What is FFF?
What is FDM? Fused Deposition Modeling (FDM) is a type of additive manufacturing process used for creating tangible 3-dimensional objects from CAD-designed digital files. Invented by S. Scott Crump in 1989, this trademarked 3D printing method uses … [Read more...] about What is FDM?
Laser melting is an additive manufacturing method that uses a laser to heat a material into a fully melted liquid form. This is essentially the same process used in laser sintering with a few technical differences. Laser sintering uses heat to … [Read more...] about Laser Melting: What Is It?
Stereolithography (SLA) is a type of additive manufacturing process used for creating tangible 3-dimensional objects from CAD designs or 3D scanned digital files. The process, invented and named by Chuck Hull in 1986, uses photo-reactive (usually … [Read more...] about What is Stereolithography?
3D printers are a specific type of industrial machine and are the primary tool used for the additive manufacturing process. 3D printers use data from CAD drawings and 3D scanners to create solid 3-dimensional objects out of some material. How it … [Read more...] about What is a 3D Printer?
According to the ASTM standard terminology definition, material jetting is a process in which droplets of build material are selectively deposited onto a build bed to develop a three-dimensional object. Many of the 3D printers from Stratasys Ltd do a … [Read more...] about Material Jetting: How Does It Work?
