Abstract
A three-dimensional (3D) printing system for preparing an object made at least partially of an expanded polymer including: a printing device for transporting and depositing a strand of expanded polymer including a blowing agent onto a surface and a 3D movement device for adjusting the position of the printing device in a predefined matrix allowing deposit of the strand of expanded polymer at a predetermined time and precise position within the matrix, the printing device includes: a feed section, a transporting section, a surface melting section, and a terminal printing head section for depositing the expanded polymer strand onto the surface, and all of sections have the same inner diameter, and the surface melting section including a solid-state welding element, a laser beam, a generator of hot gas or liquid and/or a generator of heat.
