Abstract:
An intermittent material feed type variable-lamination rapid prototyping apparatus using a linear thermal cutting system, comprising:a collapsible leg with elastic bodies installed at link-connected intersections for supporting sheet materials stacked on the collapsible leg; a friction roller for feeding the supported materials onto a conveyor belt engaged with and simultaneously driven with the friction roller through gears in a state where the friction roller is in pressure contact with one of the sheet materials, said conveyor belt configured to repeat a transfer mode and a standby mode; liftable spacing rods installed on both sides of the width of the conveyor belt for lifting each sheet material upward from the conveyor belt during the standby mode of the conveyor belt; a linear thermal cutting system for cutting the upward lifted material into a unit shaped-sheet; a computer for electrically controlling an elevated height of the spacing rods and a transfer speed of the conveyor belt and for controlling operations of the linear thermal cutting system in respective axis directions based on cutting operation data; and a prototyping jig for fixing the unit shaped-sheets to form a predetermined shape in such a manner that one sides of the respective unit shaped-sheets are bonded to and laminated on the other sides of other unit shaped-sheets that geometrically correspond thereto.
