The process works by using a projector. This projector cures a photopolymer resin, one layer at a time, curing the selected areas to be solidified according to the 3D printer model and leaving the surrounding areas uncured. Once one layer has been completed, the part is pulled up by one layer height (e.g. 50 microns) and the process repeats again.

The economic purpose of mineral processing is two-fold: firstly, it reduces the bulk of the ore that needs to be transported and processed for metal extraction by using relatively cheap methods to separate the economic minerals from gangue minerals.
Metal AM post-processing is a broad category and has long been considered the most time-intensive part of the additive manufacturing workflow. It is often more expensive and time-consuming than the process itself. And yet it is, in one form or another, taken as a given in metal additive manufacturing.

Glass Glass makers add chemicals (soda ash and an accelerant such as potassium nitrate) to silica sand to bring it to temperatures around 2450 F. Then add small amounts of metal to change the color and give the shape in hot to finally let it cool. Bronze Another example of processed materials is bronze.

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like …

The basic principle of the bending process sequence: bending from inside to outside. Bending from small to large. First fold the special shape, then fold the general shape. After the former process is formed, there is no interference with the subsequent process. Bend processing accuracy: One fold: +/-0.1mm Two fold: +/-0.2mm Tri-fold: +/-0.3mm 6.
Stamping is the term used to indicate various press forming operations such as embossing, blanking, coining, and pressing. It is the process of forming metals using pressure into the surface of metal, normally a sheet or strip. The most common operations associated with stamping are piercing, forming, blanking, and drawing.

Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock.
