Method for simultaneously scribing and filling of scribed channel, trough, trench or groove

A method of fabricating a three dimensional model from a composite model formed by a plurality of layers with the composite model comprising at least one separation material encasing and enclosing a build material, the method comprising the steps of:

• (1) depositing a build layer of the build material onto a preceding layer;
• (2) combining a scribing tool with a filling device to form a combined scribing/filling device;
• (3) conveying the combined scribing/filling device and removing at least one selected area of the build material from the current build layer and simultaneously depositing the separation material in each removed selected area of the removed build material so as to perform both removal of the build material and the depositing of the separation material simultaneously with one another as a combined step during conveyance of the combined scribing/filling device;
• and
• (4) reducing the build layer to a desired final thickness for supporting a next subsequent build layer;
• and
• (5) repeatedly repeating steps (1) through (3) for each build layer until the composite model is completed.
