Printer first, then artwork.

Geometry, stated honestly.
gates · providers · slicingThe app guarantees the model is sound. It does not guarantee the print succeeds — that stays with your slicer and your judgement.
Several minutes to well over an hour, depending on footprint and analysis pitch. A fine-pitch relief at full bed size builds a mesh of millions of triangles, then validates it and imports it into your installed slicers. The progress log shows each stage as it runs. This is real geometry computation on your Mac, not a filter.
Because the printer decides the millimetres. Usable bed size bounds the footprint, nozzle diameter sets the analysis pitch, layer height sets the floor for printable detail, and the number of filament slots sets how many colour channels the relief can use. Enter it once and every subsequent model already fits your machine.
You get an error naming the exact gates that failed and the measured values, and no 3MF is delivered. That is intentional. A model that fails a watertightness, slope, cap-depth, or articulation check would waste filament and hours, so Topoform refuses it rather than handing you a file that looks fine in a preview.
No. With no provider configured the app is completely offline and still produces full reliefs — the geometry engine runs on your Mac and never uses a model. A provider only adds optional art direction: a style suggestion and a palette mapping. It never generates geometry.
OpenAI, Anthropic, and Google Gemini with your own API key, any OpenAI-compatible endpoint, or a local LM Studio server that costs nothing and never leaves your machine. You pay those providers directly under your own account; Topoform adds no markup, no proxy, and no subscription of its own.
In the macOS Keychain, in an app-scoped item. Never in preferences, log files, or exports, and never transmitted to Silo Systems. Removing a provider removes its Keychain item.
Only when you run a generation with a provider selected: the artwork you chose and the composed prompt describing your printer and filaments. It goes straight from your Mac to that endpoint under your key. Silo Systems runs no server and receives no copy. Read the provider's own policy about prompt retention.
No — Topoform is not a slicer and writes no G-code. Open the 3MF in your multicolour slicer, map each of the four material objects to a loaded filament, then slice as usual. Purge settings, orientation, supports, and bed adhesion remain your slicer's job and your decision.
The contact sheet shows the source artwork, the four-material topology, a hypsometric relief with contours, the printable slope field, the drainage and erosion network, a material render, two raking gallery views, a cross-section, the per-scale slope budget, and a height histogram. The JSON report carries every measured number behind each gate verdict.
Yes. Set the material system to single extruder and the relief is planned as one channel — you still get the full sculpted topography, printed in one colour. Multi-material systems unlock up to four colour channels.
Topoform is a one-time Mac App Store purchase at $19.99. No subscription, no usage credits, no account. Any AI provider you choose to connect is billed by that provider, directly to you.
