nTop is a revolutionary generative design platform combining additive manufacturing workflows with advanced algorithms to create optimised components. Quite uniquely compared to traditional CAD software the geometry is not predefined. Implicit techniques generate parametric geometries, its modular and process based workflow allow for optimisation and editing at any part, without restarting from scratch.
I have used nTop in my Undergraduate Dissertation to use the density field from topology optimisation to drive a functionally graded TPMS lattice to optimise 3D printed polymer gears.
The Power of Field-Driven Design
nTop’s strength in its field-driven approach allows mathematically driven fields as opposed to discrete modeling. While discretisation may occur in FEA processes these can then be easily re-integrated into parametric geometry. Allowing functionally graded materials and lattices with variable densities.
Integration with Simulation Workflows
nTop, originally known as nTopology when it was founded in 2019 is relatively new but managed to establish itself in 3D printing design optimisation through its integration with existing finite element analysis workflows and software. One interesting application is the thermal optimisation of a radiators geometry using gyroid TPMS lattices.
Advanced Manufacturing Preparation
Its capabilities extend to G-code creation, optimising build orientation, powder removal, and other aspects that are often overlooked in early-stage design tools. nTop’s ability to make use of the limited, yet still present manufacturing constraints of 3D printing was crucial in order to automate my optimisation process.
