Systems for Horizontal Additive Manufacturing and Methods Thereof
Systems and methods for wire arc additive manufacturing systems that print in horizontal orientations are described. Horizontal WAAM 3D print systems comprise metal 3D print systems in a horizontal orientation with one or more robots operating concurrently on a work piece using one or more wire feeds and a rotating, horizontal build plate.
1 . A wire arc additive manufacturing system comprising:
a build plate defining a vertically oriented build plane and having a center point and a build axis oriented perpendicular to the build plane, wherein the build plate is configured to rotate on the build axis about center point; and
at least one robot comprising at least one print head configured to deposit a molten material onto the build plate in a series of layers disposed along the build axis to form a part.
2 . The system of claim 1 , wherein the build plate rotates at a speed from 0.5 inch per minute to 600 inch per minute.
3 . The system of claim 1 , further comprising a positioner, wherein the build plate is attached to the positioner and a motor on the positioner drives the build plate to rotate.
4 . The system of claim 1 , wherein the build plate has a circular shape and a diameter from 5 feet to 18 feet.
5 . The system of claim 1 , wherein the print head is placed at a position at 90-degree or 270-degree from a top of the build plate circumferentially around the center point.
6 . The system of claim 5 , wherein a build plate rotation speed and a print head deposition rate are coordinated such that the print head is at a constant location during printing.
7 . The system of claim 1 , wherein the print head is positioned at one end of an extendable arm of the at least one robot such that the print head extends to reach a desired location to print.
8 . The system of claim 1 , wherein the at least one robot is mounted on a rail arranged in a print direction such that the rail moves the at least one robot as the part prints.
9 . The system of claim 1 , wherein the at least one robot is mounted on a first mobile platform comprising a riser; wherein the at least one robot moves freely horizontally and vertically.
10 . The system of claim 9 , further comprising a laser tracking system to position the at least one robot at a desired location for printing.
11 . The system of claim 9 , wherein the mobile platform is a manually guided vehicle or an autonomously guided vehicle.
12 . The system of claim 1 , further comprising a second robot supported on a second mobile platform comprising a riser; wherein the second robot moves freely horizontally and vertically.
13 . The system of claim 12 , wherein the second robot comprises an end effector assembly configured to attach a tool selected from the group consisting of: a print tool, a weld tool, a machining tool, an inspection tool, and an imaging tool.
14 . The system of claim 12 , wherein the second mobile platform is a manually guided vehicle or an autonomously guided vehicle.
15 . The system of claim 1 , wherein the part has a cylindrical shape or a dome shape.
16 . The system of claim 1 , further comprising a second build plate defining a vertically oriented build plane and having a center point and a build axis oriented perpendicular to the second build plane, wherein the second build plate is configured to rotate on the build axis about center point; and a third robot comprising at least one print head configured to deposit a molten material onto the second build plate in a series of layers disposed along the build axis to form a second part.
17 . The system of claim 16 , wherein the second build plate rotates at a speed from 0.5 inch per minute to 600 inch per minute.
18 . The system of claim 16 , wherein the build plate and the second build plate align along the build axis, the build plane of the build plate faces an opposite direction from the build plane of the second build plate.
19 . The system of claim 16 , wherein the third robot is mounted on a rail arranged in a print direction such that the rail moves the third robot as the second part prints.
20 . The system of claim 16 , wherein the third robot is mounted on a mobile platform comprising a riser; wherein the third robot moves freely horizontally and vertically.
