The word "sintering" is correct in written English.
It is used in materials science to describe the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Example: "The ceramic components were produced through a sintering process at high temperatures." Alternatives include "firing" or "compaction."
Among the 3D printing technologies used by Morris Technologies is laser sintering.
Sintering is a way of making objects by shaping them out of powder and then heating the powder to just below its melting point so that the particles adhere to one another.
It recently bought an 80% stake in Phenix Systems, a French provider of direct-metal selective laser sintering.
Powder can be spread onto a tray and then solidified in the required pattern with a squirt of a liquid binder or by sintering it with a laser or an electron beam.
Components are made by sintering it in powder form in a mould, at 1,000ºC, for several hours.
This consists of synthetic diamond powder that is formed into a thin plate and bonded to tungsten-carbide studs by sintering (fusing by heating the material below the melting point).
Industrial metal printers, for instance, use a process known as selective laser sintering (SLS), in which a powerful laser is fired into a bed of powdered metal to sinter particles together, layer upon layer, into the required outline, until the object is built up.
A major breakthrough occurred in 1961, when Robert Coble of the General Electric Company in the United States demonstrated that alumina (a synthetic polycrystalline, Al2O3) could be sintered to optical density and translucency using magnesia (magnesium oxide, MgO) as a sintering aid.
Once finished, the solidified shape is cleaned of residual slurry and heated in a furnace to sinter the ceramic particles together.More work will be needed to turn the process into a production-ready system.
The layering of powders or droplets that are then sintered into solidity, or cured with heat or ultraviolet light, allows spaces to be left inside the product.
Some 3D printers spread metal powders on the print table and sinter the pattern with lasers or electron beams, rather than using masks.
