The word 'sinter' is correct and usable in written English.
It is a verb meaning 'to form a compact mass of fine particles' or 'to cause to coalesce into a single body.' For example: "The water droplets sintered together as they evaporated in the hot air."
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.
Workers at the factory grind mixed plastics into powdery flakes, spread the material over a polymer skin, cover it with another skin and sinter it.
Some 3D printers spread metal powders on the print table and sinter the pattern with lasers or electron beams, rather than using masks.
Then they stack these one on top of another, like layers of a sandwich, sinter them together at a temperature of 800°C, and laminate them.
And some of its machines, which cost up to 1.5m yuan (about $250,000), can do more than just sinter plastics, wax and sand; they can sinter metals directly.Indeed, one of the country's largest 3D printers (though it was not made by AFS) does just this.
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.
It can also be melted into the required pattern with a laser in a process called laser sintering, a technology which EOS, a German firm, uses in its additive-manufacturing machines.
Another example of the scale of the potential is the production of a chess set just a few millimetres high, which includes a rook complete with internal spiral staircase.Drummond Hislop Director Sustainable Engine Systems LondonSIR – I should like to know who concluded that the violin on your cover, made with a laser-sintering 3D printer, "plays beautifully"?
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.
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.
