Abstract
A fast and economical system and methods directed to low-fidelity fabrication of three-dimensional (3D) objects using 3D printing. The invention facilitates rapid prototyping by providing a wireframe structure in the form of the underlying design structure of a 3D model, which may be useful for a variety of reasons including to provide a prototype preview that may be used for design validation of a 3D model.
Claims15
A method for adapting a printing device for fabrication of a wireframe structure on a surface, the printing device including a print head, the steps comprising of:
- registering parameters of the printing device, wherein the parameters include an angle of the print head defined from a horizontal axis and a diameter of the print head;
- calculating from the angle and the diameter a depth defined along a vertical axis at which the print head deposits a material;
- and
- defining a plane at the angle of the print head at which the print head deposits the material, the depth and the plane defining a portion of space viable for printing the wireframe structure on the surface.
A system for fabricating of a wireframe structure on a surface, the system including a processor, a controller and a print head, the system comprising:
- a processor that executes g-code causing the print head to extrude filament material in the form of a mesh pattern, the mesh pattern determined from one or more parameters of the print head, the one or more parameters including an angle of the print head defined from a horizontal axis and a diameter of the print head.
A method for converting a 3D model to a wireframe representation for fabrication by a printing device, comprising the steps of:
- slicing the 3D model into one or more segments, each segment defined by a thickness equal or less than a distance a print head of the printing device can descend without colliding with printed material;
- and
- defining a mesh pattern to replace one or more surfaces of the 3D model, wherein the mesh pattern is defined to prevent collisions between printed material.
