Abstract
A three dimensional object may be formed by forming voxels on a sheet of material and positioning the voxels together to form the three dimensional object by rolling up the sheet.
Claims19
A method of forming a three dimensional object, comprising:
- unrolling a sheet of material from an intake roll;
- feeding the sheet of material to a voxel forming station;
- in the voxel forming station, selectively activating voxels in or on the sheet of material such that a portion of the sheet or material on the sheet is activated and leaving a second portion of the sheet or material on the sheet unactivated, wherein the activated portion has different mechanical properties than the unactivated portion;
- rolling up the sheet under dynamic tension to form the three dimensional object, wherein tension applied to the sheet varies depending on the mechanical properties of the sheet resulting from the presence of activated and unactivated voxels in the sheet;
- and
- removing the unactivated portion to reveal the three dimensional object by mechanical, chemical, and/or thermal processes.
