Abstract
A three-dimensional printing system for preparing a three-dimensional object made at least partially of an expanded polymer includes a printing device configured to prepare an expandable polymer melt and deposit a strand of expandable, expanding or expanded polymer onto a surface and a three-dimensional movement device for to enable depositing of the strand of expandable, expanding or expanded polymer at a predetermined time at a precise position within the three-dimensional matrix. The printing device includes a feed section at an upstream end of the printing device, a heating section, a pressurizing section, a blowing agent supply line, a mixing section, a cooling section and a terminal printing head section at a downstream end of the printing device including a die configured to deposit the strand of the expandable, expanding or expanded polymer onto the surface.
