However, there were still (financial) clouds on the horizon with European Powder Metallurgy Association (EPMA) president Ingo Cremer in his opening speech expressing concern at the depressing influence of the recent and continuing turmoil in world markets, not to mention the challenge of volatility ...
How does metal 3D printing work? The basic fabrication process is similar for both SLM and DMLS. Here's how it works: The build chamber is first filled with inert gas (for example argon) to minimize the oxidation of the metal powder and then it is heated to the optimal build temperature...
Powder metallurgy is a method by which very tiny ingots are formed. The liquid steel is dripped through a nozzle and is “atomized” by liquid or gas sprays that near-instantly solidify the steel as powder. Typically nitrogen is used in the production of tool steel. Each particle of the po...
It does this by depositing printing material such as plastic, metal, or ceramic in precise layers according to the design instructions from the slicing software. 4. Layer bonding As each layer is added, the material fuses or bonds with the previous layer. This additive process continues until ...
parts through a rather toasty furnace. The goal is to control the temperature so it reaches just below the melting point of your parts' primary metal … but not quite. The sintering process causes the metal particles to bond together so you get a part that does what you need it to do....
Copper contains metallic bonds and so conducts electricity. Rubber contains covalent bonds and so does not conduct electricity. It protects the user from getting an electric shock.
does“Iridium Point Germany” nib contains no iridium but use osmium So what’s all this business about $3.6 billion per troy ounce? Are there metals far scarcer than iridium and enormously more expensive than gold — while at the same time, non-radioactive or very, very nearly so? As...
This technique is called powder metallurgy. A third method of making alloys is to fire beams of ions (atoms with too few or too many electrons) into the surface layer of a piece of metal. Ion implantation, as this is known, is a very precise way of making an alloy. It's probably ...
(SLS), sintering applies a layer of material, using a laser to trace it to bind it to the layer below as it does so. SLS tends to offer more precision than methods like fused filament fabrication (FFF) because it uses a high-powered laser to fuse fine powder particles layer by layer,...
