Therefore, both build direction and in-plane raster directions are considered by the topology optimization algorithm, especially for the latter, which is calculated through deposition path planning.
To ensure the fabrication of the designed scaffolds, the generated contours are optimized for a continuous, interconnected, and smooth deposition path-planning.
Among them, material deposition plan can frequently interrupt the AM process due to tool-path changes, tool start-stop and non-deposition time, which can be challenging during free-form part fabrication.
The proposed model is solved for minimizing the change in deposition modality by maximizing the continuity and connectivity in the material deposition plan.
The system control software directs the material deposition according to the tool path to form a layered 3D scaffold.
Our proposed system meets the requirements of material deposition (RP) and material removal (CNC) at the process planning and manufacturing level.
The basis of planning the deposition paths is the beads overlapping model (BOM).
This paper highlights the development of 'Multi-arm Bioprinter (MABP)' capable of concurrent multi-material deposition with independent motion path and dispensing parameters including deposition speed, material dispensing rate, and nozzle travel velocity for use in tissue engineering.
Several deposition paths were designed.
These connections bridge diverse areas such as building modelling, equipment simulation and visualization, character modelling and animation, collision detection, navigation, path planning, materials and lighting, and interaction through game controllers and user interfaces.
