3D Topology Optimizer
Read full descriptionHide full description
3D Topology Optimizer reduces the weight of a 3D part without sacrificing its strength — entirely on your device, with no cloud upload required. Load an STL model, mark contact surfaces, applied loads (forces and moments), and functionally important faces that must never change. The app then runs a real finite-element simulation and a SIMP topology optimization directly on iPhone, iPad, or Mac to determine which material actually contributes to strength and which can be removed. FEATURES • Automatic hole detection — cylindrical bores are recognized and automatically protected from the optimizer • Calculated entirely on-device — your geometry and load cases never leave your device • High-resolution STL export for 3D printing or CNC machining • Built-in parametric templates (bushings, brackets) to get started without any CAD file • Wireframe and shaded 3D viewer with axis indicators for precise face tagging WHO IT'S FOR Engineers, product designers, makers, and students who design 3D-printed or CNC-machined parts and want a fast, private way to see where material can be safely removed before committing to a print or a machining run. All calculations are a simplified, linear finite-element approximation and do not replace certified FEA software or review by a qualified engineer. Always verify results independently before manufacturing load-bearing parts.

Verdict
The clearest difference is in-app purchases: OCTO Digital Driver™ at none against 3D Topology Optimizer's 1. OCTO Digital Driver™ also leads on ads (none vs shown) and iOS requirement (14.0 vs 17.0). 3D Topology Optimizer's advantage is update cadence (every 6 days vs every 6 weeks). On price and device support there is nothing between them.
