Summary: | The present invention relates to a three-dimensional printing system for preparing a three-dimensional object made at least partially of an expanded polymer comprising:i) an autoclave,ii) a printing device (10) for preparing an expandable polymer melt and for depositing a strand of the expandable, expanding or expanded polymer onto a surface andiii) a three-dimensional movement device (10) for adjusting the position of the printing device (10) in a predefined three-dimensional matrix so as to allow to deposit the strand of expandable, expanding or expanded polymer at a predetermined time at a precise position within the three-dimensional matrix,wherein the printing device (10) comprises:a) a feed section (16),b) a cooling section (18),c) a backflow prevention section (20),d) a heating section (22) ande) a terminal printing head section (24) including a die for depositing the expandable, expanding or expanded polymer strand onto the surface. |
