Embodiment Construction

[0085] It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of example only, since various changes and modifications in accordance with the detailed description will be within the spirit and scope of the invention. It will be apparent to those skilled in the art.

[0086] The method and apparatus of the present disclosure are applicable to any system that requires precise and rapid positioning of the tool relative to the platform, but it is particularly applicable where the mechanical limitations of the machine do not allow the tool to follow a complex two-dimensional path and there are sharp turns to define object outlines) low-cost additive manufacturing systems that maintain high speeds.

[0087] figure 1 An extrusion-based printer (FDM) is illustrated. The printer shown comprises a filament supply 1 in the form of a spool of thermopolymer filament. The wire 2 is supplied to the extru...

Abstract

A printer for printing a 3D object based on a computer model, the printer comprising a tool for extruding or solidifying material, a stage supporting layers of the object; motion structure defining the shape of the layers, and a controller configured to make a path to be followed for making the object. To increase at least one of the speed and the precision by which the object is made, the controller is configured to define the path by defining a plurality of line segments and by defining transition segment for insertion between the line segments. The controller is further configured to only demand material deposition along the line segments and not along the transition segments.

Description

technical field [0001] The present disclosure relates to a method and a printer for printing a 3D object based on a computer model. The printer to which the present disclosure relates includes a tool configured to switch between an activated state and a deactivated state based on tool commands. When activated, it adds material to a specific location, referred to herein as the add location. The add position is the position in the object's layer. The location of addition is determined by the tool position of the shape-defining structure, which is usually an integral part of the tool. The printer also includes a stage arranged to support the layer of the object while the layer of the object is defined by the tool. The printer also includes a motion structure configured to receive motion commands and define the shape of the layer based on its movement through the shape-defining structure. The printer also includes a controller configured to communicate with the tool and the mo...
