A Continuous Toolpath Strategy from Offset Contours for Robotic Additive Manufacturing
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2022 Abstract Toolpath planning is an essential component of robotic additive manufacturing. An efficient toolpath strategy allows parts to be made that are geometrically accurate, free of defects, have good mechanical properties and low residual stress.

Toolpath Strategies for 5DOF and 6DOF Extrusion-Based Additive Manufacturing [PDF]
Applied Sciences, 2019 This paper introduces two new deposition-strategies for five degrees of freedom (5DOF) and 6DOF extrusion-based additive manufacturing (AM), called the tool path projection- and parent-child-approach, respectively. The tool path projection method can be automated, and allows for the generation of concentric shells layers, which remedy geometrical ...

3D Printing of Objects with Continuous Spatial Paths by a Multi-Axis Robotic FFF Platform
Applied Sciences, 2021 Conventional Fused Filament Fabrication (FFF) equipment can only deposit materials in a single direction, limiting the strength of printed products. Robotic 3D printing provides more degrees of freedom (DOF) to control the material deposition and has ...

A Mixed Double-Sided Incremental Forming Toolpath Strategy for Improved Geometric Accuracy [PDF]
Journal of Manufacturing Science and Engineering, 2015 Double-sided incremental forming (DSIF) is a relatively new dieless forming process which uses two hemispherical ended tools, one on each side of the sheet, moving along a predefined trajectory to locally deform a peripherally clamped sheet of metal.
