METHOD AND DEVICE FOR THE COMPUTER-ASSISTED GENERATION OF 3-DIMENSIONAL FOAM STRUCTURES FROM A MIXTURE OF A POLYMERIC MATERIAL AND A PROPELLANT

摘要

the invention relates to a method for computer-assisted generate 3 - dimensionaler bubble plastics.in which a mixture of a polymerwerkstoff and a propellant within a extrusionseinheit (2) to the extrusionseinheit (2) and nozzle (6) is being transportedthe mixture of polymerwerkstoff and propellant within the extrusionseinheit (2) thermal energy is supplied to the mixture under elevated pressure through the nozzle (6) is extruded.the mixture according to a given 3d model voxelweise to druckunterlage (8) will take placewith the situation of the druckunterlage (8) to the beabstandet arranged nozzle (6) in three dimensions variierbar and by controlling the treibmittelanteils and / or the entry of thermeuropean energy and / or the austragsgeschwindigkeit adjust the density and the height and width of a huge voxel of schaumstruktur (10) during the erzeugungsprozesses under thethe 3d computer model is realized.;the invention relates to a device for the computer-assisted also generate 3 - dimensionaler bubble plastics.
