Working Principle

Slicer Software vs. Tracer Software

This “Tracer” software 3D printing method is for extrusion based printing.

This patent-pending method creates self supporting loops by maintaining the same increment along each surface. Each successive loop is equidistant from the previous.

3D Model

3D Model

This is a simplified 2D view for a 3D model of a vase. In both methods we start with a 3D model

Increment Slices

Increment Traces

Slices are equal increment sections in the z-axis

along z-axis

along surface

Traces are equal increment sections along surfaces

3D view

3D view

Each resulting trace loop is equidistant from the previous loop. Thus, each loop is traced from the previous loop.




For simplicity, the above example was for a rotationally symmetric vase. The resulting tracer print paths happened to be flat. However, this is not often the case. Typically resulting paths are non-planar

The following example of a snub cube results in non-planar tracer print paths.

First Slice

Seed Loop

In this tracer case the first (seed) loop is a flat pentagon on the build plate just like the first slice

Z-axis Increments

Surface
Increments

Each successive trace loop remains equidistant from the previous.
Note how the angled snub portion does not have stair-stepping

Support and Infill

No Support Nor Infill

Infill is also unnecessary because it is just internal (non-breakaway) support
