Parametric path generation
Reusable path families from explicit geometric and process parameters.
03 / ToolpathsEXPERIMENTAL
Advanced toolpath & motion generation.
Generating manufacturing motion directly from process intent rather than relying only on conventional planar slicing.
MYCNC3D develops experimental methods for generating toolpaths and machine motion adapted to unconventional FDM processes, including variable deposition geometry, non-planar trajectories and flow-aware speed control.
Project overview
The toolpath becomes an engineering object.
Multiple families of generated toolpaths have been physically printed and evaluated.
MYCNC3D develops experimental methods for generating additive-manufacturing trajectories directly from geometric and process parameters. Research includes parametric path generation, variable deposition geometry, non-planar trajectories, path ordering, motion continuity, machine-specific post-processing and flow-aware speed control.
A geometrically correct path is not automatically a reliable manufacturing path. Extrusion demand, acceleration, intersections, local bead geometry, continuity and machine constraints must all be considered during trajectory generation.
Current research focuses on converting successful geometry-specific methods into reusable and parameterised trajectory-generation components.
Why it matters
Complex motion requires process-aware trajectory generation.
A geometrically valid path is not automatically a good manufacturing path. Extrusion throughput, acceleration, local bead geometry, intersections, continuity and machine kinematics all affect whether the motion can be executed reliably.
Toolpath generation must therefore connect geometry with physical process limits.
Current focus
What we are investigating now.
Variable deposition geometry
Local control of bead width, height or path shape.
Flow-aware speed control
Adapting machine speed to local extrusion demand and volumetric-flow limits.
Non-planar trajectories
Generating curved or inclined paths beyond planar layer assumptions.
Path ordering & continuity
Reducing unnecessary travel, intersections and discontinuities.
Machine-specific post-processing
Converting generic manufacturing intent into commands compatible with target kinematics and controls.
Engineering approach
Build the path, print it, analyse the result.
Experimental trajectories are generated, inspected and physically validated whenever possible. The printed result is used to refine geometric rules, process parameters and path sequencing.
Current status
EXPERIMENTAL
Multiple families of generated toolpaths have been physically printed and evaluated. The current objective is to convert successful geometry-specific methods into reusable trajectory-generation components.
Next milestone
From geometry-specific scripts to a reusable toolpath engine.
The next milestone is to generalise trajectory generation across families of geometries while systematically accounting for extrusion flow, speed, acceleration, path continuity, intersections and machine constraints.
Progress toward UNDER DEVELOPMENT will be reached when the same generation logic can be parameterised and reused without being rewritten for each individual test geometry.
Integrated platform
Toolpaths connect digital intent to physical motion.
Advanced toolpath generation is the software bridge between geometry, multi-axis motion and extrusion capability. It is where machine constraints and process objectives are converted into executable manufacturing motion.
