3D Topology Optimizer

Less material, same strength – right on your device.
The free app for iPhone, iPad and Mac reduces the weight of a 3D part without sacrificing its strength. Load an STL, mark supports, loads and important faces – the finite-element simulation and SIMP topology optimization run entirely on device, with no server.

From STL to a lighter part

Calculated on the device

A finite-element simulation and a SIMP topology optimization run on iPhone, iPad or Mac – your geometry and load cases never leave your device.

Automatic hole detection

Cylindrical bores are recognised and automatically protected from the optimizer.

High-resolution STL export

Export the result for 3D printing or CNC machining.

Mark loads and faces

Define contact surfaces, forces and moments and functionally important faces that must never change, directly on the model.

Parametric templates

Built-in templates (e.g. bushings and brackets) help you get started – no CAD file needed.

3D viewer

Shaded and wireframe view with axis indicators for precise face tagging.

Your geometry stays on your device

Calculation and optimization run entirely on device; there are no servers and no user account. The free app shows ads from Google AdMob; it asks for your consent and reads the advertising ID only with your permission. Details: Privacy

Important: all calculations are a simplified, linear finite-element approximation and replace neither certified FEA software nor review by a qualified professional. Verify results independently before manufacturing load-bearing parts.
