  • Lamination forming system
    Patent number: 11331840
    Abstract: A lamination forming system includes a melt extruder, a nozzle head and a carrier unit. The melt extruder is configured to melt a plastic raw material into a plastic melt and to deliver the same. The nozzle head includes a sprue channel that has an inlet connected to the melt extruder for entry of the melt plastic into the sprue channel, and an outlet disposed distally from the inlet to deliver the plastic melt from the sprue channel. The carrier unit includes a slide table controllable to move relative to the nozzle head. The slide table is configure to carry the plastic melt outputted from the nozzle head.
