Three-dimensional objects printing method

A method of 3D object printing, comprising:

• providing a 3D object manufacturing apparatus including at least a module configured to analyze a slope or curvature change ratio of a 3D object surface and operate a material deposition module to deposit 3D object material across a cross-section of a 3D object with at least one of a plurality of layers forming the 3D object that has a characteristic different from other layers;
• and
• manufacturing the 3D object by depositing, with the material deposition module, the 3D object material so that the 3D object includes the plurality of layers with the at least one layer that has a characteristic different from the other layers,
• wherein the characteristic that the at least one layer that is different from the other layers is layer height and/or layer width,
• wherein adaptation of the characteristic of layer height and/or width is performed by one of a group of parameters consisting of a change in a gap between the material deposition module and previously deposited material layer;
• material deposition module movement speed adjustment, and extrusion material temperature.

• and
• manufacturing the 3D object with the material deposition module by depositing the 3D object material from at least one nozzle of the material deposition module and without further mechanical manipulation of the material, so that the 3D object includes the plurality of layers with the at least one layer that has a characteristic different from the other layers,
• wherein the characteristic that the at least one layer that is different from the other layers is layer height and/or layer width,
• wherein the at least one layer that has a characteristic different from the other layers is determined by the module analyzing at least three layers including the at least one layer prior to being printed, a layer above and a layer below the at least one layer.
