# Printers and 3MF downloads

Tools that make or read a model show a **3D preview** with a printer list underneath. Pick your printer once; every tool remembers it in this browser.

## What you get

| Download | Best for |
| --- | --- |
| **3MF for your printer** | Opening straight in your slicer, ready to slice |
| **STL** | Any slicer or printer, or sharing the model |
| **GLB** | Web 3D viewers, AR on phones, design tools |
| **Screenshot (PNG)** | Listings, quotes and messages. Always free |

## What's inside the 3MF

- **The model, centred on your printer's bed**, sitting flat on the plate.
- **A thumbnail**, so your slicer's file browser shows what it is.
- **Print settings for the quality you picked**, written into the file for that one object:

| Setting | Layers | Walls | Infill | Top / bottom |
| --- | --- | --- | --- | --- |
| Standard | 0.20 mm | 2 | 15% | 5 / 3 |
| Fine | 0.12 mm | 3 | 15% | 7 / 5 |
| Draft | 0.28 mm | 2 | 10% | 4 / 3 |
| Strong | 0.20 mm | 4 | 40% gyroid | 6 / 5 |

- **No brim**, unless the part is more than four times taller than its narrowest side. Then it gets a small 3 mm outer brim so it doesn't tip over.

Everything else (temperatures, speeds, cooling, supports) comes from your printer's own profile in the slicer, which its maker keeps up to date.

## Opening it in your slicer

1. Open your slicer and pick your printer's profile (the preview tells you which one, for example "Anycubic Kobra X 0.4 nozzle").
2. Open the 3MF. If the slicer asks whether to load the settings in the file, choose **yes**.
3. Pick your filament and slice.

The 3MF works in Bambu Studio, OrcaSlicer, Anycubic Slicer Next, Snapmaker Orca, Creality Print, Elegoo Slicer and PrusaSlicer.

## Tuned printers

Most printers use their maker's own profile plus the settings above. The **Anycubic Kobra X** also gets settings tuned from real test prints: Arachne walls (better on thin walls and rings), no slow-down on gently leaning walls, and faster inner walls and infill within the printer's limits.

## Does it fit?

The preview checks the part against your printer's bed and height, and says so in green or red. Turning a part 90° on the bed counts as fitting. See every printer's bed size on [Supported printers](/printers).
