Spherene has integrated linear-static structural simulation into the browser-based sphereneNXT 2.0.0 platform. Users can create ADMS, TPMS, beam or other internal architectures, mesh the model, define material, loads and constraints, then inspect stress and displacement in one environment. The value is a shorter design loop, not a general CAE replacement or automatic manufacturing qualification.

Where the workflow becomes shorter

A separate toolchain requires geometry export, remeshing and manual return of changes. Integrated analysis lets designers compare architecture, relative density, wall thickness or gradients in the same project. Speed is real only when geometry version, material data and load case remain traceable.

What linear statics can and cannot do

Linear-static analysis assumes small deformation, a linear material law and time-invariant loading. It helps with stiffness, load paths and early concept screening. It does not automatically represent plasticity, contact, buckling, fatigue, impact, viscoelasticity, creep or thermal-mechanical coupling. If one of these governs failure, the built-in analysis is a screen.

Meshing is not a background option

Thin TPMS walls, small cells and nodes may require many elements. A coarse mesh can smooth stress and over-stiffen the structure; a fine mesh raises cost. At least three mesh levels should compare displacement, reactions, strain energy and stress over an engineering region. A single peak at a mathematical singularity is not a sound acceptance metric.

Material model: the printed state, not a bulk datasheet

A moulded or wrought bulk datasheet rarely represents a printed thin-wall lattice. Orientation, moisture, temperature and strain rate matter in polymers; powder, build direction, heat treatment, residual stress and surface condition matter in metals. Representative solid and lattice coupons are needed to derive material parameters or an effective model.

Ideal CAD versus as-built lattice

Wall-thickness variation, down-facing surfaces, fused cells, trapped powder or resin and skin-to-lattice defects change stiffness and fracture. Inspect critical geometry by section, mass, optical measurement or CT. A comparative analysis should include measured geometry or thickness distributions.

Boundary conditions and loads

Many models fail at the fixture. A perfectly fixed surface can create artificial peaks, while a point load may not represent real contact. Model interfaces, skins, fasteners or load spreaders to decision-relevant detail, and check reactions and equilibrium.

Physical validation ladder

Begin with material and cell coupons, then a subcomponent containing the critical transition, and finally the full part. Record stiffness, displacement, failure mode and variation, not only ultimate load. Correlation should verify a predefined acceptance range rather than fit a curve after the event.

Verified fact, company claim and release gate

Version 2.0.0 verifiably adds linear-static simulation beside internal-architecture design. ADMS performance, optimisation and print-readiness claims come from Spherene. Use the model for release only when mesh convergence, an as-built material model, geometry inspection and physical testing agree. Until then it is a fast, valuable development tool rather than qualified evidence.
