Abstract
A shape can be 3D printed by advancing a continuous length of material past a cutting head, cutting the material along one or more paths, providing adhesive on a surface of the material, and spirally winding the material onto a spool, such that the cut paths on each layer of the spiral are in alignment according to the 3D printed shape. A 3D printing system includes a material infeed configured to provide a supply of sheet material, a cutting head for cutting the material, a glue applicator, and a gathering spindle configured to rotate such that the material is spirally wound onto the spindle.
