• Each layer rapidly solidifies on the previous one to sequentially build a 3-D image.
• An application known as "Quickslice" can be used to create the CAD file necessary to input into the machine.
• The acrylic sheet acts a vacuum hold to lower material flow.
• the extruder head is attached to a 3-D motion axis
• polymer leaves the extrusion tip above its melting temp to form two-dimensional cross sections.
