Abstract
Paper describes a new manufacturing method based on the most advanced small scale laser sintering technology able to shape solid metallic objects being composed of nanophased powders. New development in powder feeding will be illustrated being able to feed particles down to three microns medium particle size using combination of different mechanical and physical principles. For hybrid objects possibility with material change on the flight is included. Several peripheral devices for process control are implemented like online temperature control, oxygen control in the process chamber, shape control of processed geometries and integrated observation microscope. Fully atomization is assured by special designed software and industrial standards of PXI technology. Agglomerated nanophased systems were developed to respond to the needs of micro fabrication in terms of phase sets, particle sizes and shapes.
