Printing an AI-generated model

Text-to-3D tools will hand you an STL or OBJ in a minute. Getting that onto a printer is the other half, and from an iPad it used to have no answer at all. Handoff3D takes the file the generator gave you, sizes it, stands it up, gives it a flat bottom if it needs one, and writes a print-ready Bambu file — in Safari, on the iPad.

Free, no account, nothing installed. Works in Safari on an iPad or an iPhone.

The three things generated models get wrong

They have no size

A generated model is usually a couple of units tall, or a couple of thousand, with no relationship to millimetres at all. Whatever it arrives as, type the height you actually want.

They are rarely the right way up

Generators do not think about which face touches the plate. Each piece is stood up in a way that will print, and you can turn it yourself if you disagree.

They have no flat face

This is the big one. A generated figure is a closed shape floating in space, touching the plate at a single point. Taking a slice off the bottom gives it something to stand on, and you choose how deep the cut goes while watching the footprint it produces.

Getting the file out of the generator and into Files

Download it in Safari and it lands in Files, under Downloads. If the tool only offers GLB or GLTF, look for an STL or OBJ option — those are what a printer wants, and most generators offer at least one of them.

What it will not fix

Generated models are frequently hollow where they should be solid, or carry detail finer than a nozzle can lay down, or are made of surfaces that do not quite close up into a solid object. Sizing and standing up will not repair any of that. If a print fails in a way that looks like the model rather than the printer, the honest answer is usually to generate it again from a simpler prompt.

Common questions

Can I 3D print an AI-generated model from an iPad?

Yes. Download the STL or OBJ the generator produced, open Handoff3D in Safari, size it, flatten the bottom if it needs one, and save a print-ready Bambu file. Bambu Handy then sends it to the printer.

Why will my AI-generated model not sit flat on the plate?

Text-to-3D tools produce closed shapes floating in space, with no flat face anywhere on them. Cutting a thin slice off the bottom gives the model a flat footprint to stand on.

What file should I export from an AI 3D generator?

STL or OBJ. Both are read directly. GLB and GLTF are display formats, and most printing tools, this one included, do not take them.
