CONTOUR CRAFTING EXTRUSION NOZZLES

摘要

An automated extrusion construction system may include an extrusion nozzle configured to extrude construction material in a substantially horizontal direction against an elongated and substantially vertical surface. An extrusion nozzle may have a height adjustment mechanism configured to adjust the height of an outlet in response to level deviations in the surface on which the construction material is extruded by the extrusion nozzle. An automated extrusion construction system may include a slicing mechanism configured to controllably slice through the extruded layer.

主权项

1. A process for constructing a wall having a rectangular opening therein comprising:
extruding a substantially horizontal layer of construction material; covering the upper surface of the extruded layer across the portion thereof which lies at the bottom of the desired rectangular opening with a layer of anti-adhesion material; extruding one or more additional substantially horizontal layers of construction material, each on top of the preceding extruded layer, until the top of the last extruded layer substantially coincides with the top of the rectangular opening; slicing though each of the one or more additional extruded layers at locations which coincide with the left and right sides of the rectangular openings after each of the one or more additional extruded layer are extruded but before the next later is extruded; covering the upper surface of the last extruded layer across the portion thereof immediately below the top of the desired rectangular opening with a layer of anti-adhesion material; extruding one or more additional substantially horizontal layers of construction material, each on top of the preceding extruded layer; and pushing out the block of extruded layers at the location of the rectangular opening, thus creating the rectangular opening in the wall.
