Cost-effective manufacturing by laser
sintering
The new Eosint M 270 laser sintering machine manufactures metal components in small, medium and even large volumes by fusing successive layers of powder using data from a sliced CAD model.
Rapid manufacture of metal components in small, medium and even large volumes by fusing successive layers of powder using data from a sliced CAD model is fast and cost-effective with the new Eosint M 270 laser sintering machine Manufactured by the German company, EOS, whose UK subsidiary is in Warwick, the machine is equally suitable for manufacturing tooling such as plastic injection and die-casting moulds

Laser sintering to be demonstrated at TCT
The EOS stand at this year's TCT Show will present to visitors a range of plastic components that have been laser sintered directly using its Eosint P machines and the latest powders.
EOS is international leader in laser sintering technology.
In the latest machine, it has used a 200W Yb fibre laser which is capable of being finely focused to 100um diameter, allowing greater detail resolution on the surface of the part than has been possible up till now.
However, if any particular area does not require such close definition, the focus can be varied to achieve an optimum balance between required detail accuracy and sintering speed.
Components are built at between 2 and 20mm3/s in a 250 x 250 x 215mm working area within the gas-tight process chamber of the Eosint M 270.
Such fast build times result from using scanning speeds up to 3m/s and also from the Yb laser's short wavelength, which is absorbed efficiently as thermal energy into the metal powder.
A further contributory factor to high productivity is the quick recoating time, giving only a short delay between the end of laser sintering the previous layer and the start of the next cycle.
To practice what it preaches, EOS manufactures certain parts for the M 270, such as the handle of the process chamber, by producing them on its own metal and plastic laser sintering machines.
