Laser sintering produces parts directly
from CAD
Short process chain for rapid prototyping and manufacture of plastics components directly from CAD data using the laser sintering process minimikses any risk of error.
A new machine has been introduced EOS for rapid prototyping and manufacture of plastics components directly from CAD data using the laser sintering process As the process chain is short, finished components are produced rapidly and the risk of error is minimised

Rapid prototyping goes into production too
Laser-sintering saves time and money for prototyping during product development, but can now also be used in production too. EOS will show how at the K 2001 show in Duesseldorf, Germany.
Laser sinter systems meet Formula One pressures
Two laser sintering systems - including a double-laser one - manufacture hour by hour racing car components directly from thermoplastic powders on the basis of three-dimensional CAD data.
Eosint P 380i offers a build envelope of 340mm x 340mm x 620mm and includes the company's patented exchangeable frame system for rapid job turnaround.
At the same time, improvements have been made to the top system, EOSINT P 700.
With its large build volume of more than 0.15 cubic metre and twin 50 Watt lasers, the P 700 has undergone an upgrade to improve further the detail resolution and surface quality of the plastic parts as well as to increase productivity.

Laser sintering expertise brought to the UK
German rapid prototyping systems maker is bringing a wealth of rapid manufacturing technology and experience based on laser-sintering machines and metals, plastics and sands powders.
Laser very fine grain metal powders to make moulds
TransCAT took only 16h using very fine-grained metal powders in a laser-sintering system to build the core and cavity of a plastics injection mould for producing thin-walled fan wheels.
The upgrade features are automatically included in all new systems and are available as retrofits for existing machines.
Both the Eosint P 380i and P 700 systems are available with a range of peripheral devices for integrated process chain management (IPCM), including automatic powder feeding system and unpacking and sieving station.
IPCM offers a high level of automation and ease of handling, even for large volumes of powder material.
The powder bed with the laser-sintered parts can be removed from the machine immediately after job completion by means of the exchangeable frame system and docked onto the unpacking and sieving station, from where unsintered powder is returned automatically via a mixing unit back to the machine for use in the next job.
Several machines can be fed from a single IPCM system, or multiple IPCM systems can feed different powder types to the same machine, providing maximum flexibility, efficiency and user-friendliness for automated e-Manufacturing.
EOS continues to develop innovations for all steps of the process chain.
For data preparation there is a new version of the surface-oriented data preparation software Eospace V3.0, which automatically places parts in a surface-oriented way to optimise utilisation of the build envelope.
With the help of the new Interlock Check, parts are positioned without interference and it is now also possible to place small parts within bigger parts if it is geometrically possible to remove them after manufacture.
Lastly, for the efficient smoothing and processing of the part surfaces after the build process, EOS has developed various automated processes under the brand name of AutoFinish.
