              risks associated with Your exercise of permissions under this License.
        
           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or consequential damages of any character arising as a

              work stoppage, computer failure or malfunction, or any and all
              other commercial damages or losses), even if such Contributor
              has been advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,

              defend, and hold each Contributor harmless for any liability
              incurred by, or claims asserted against, such Contributor by reason
              of your accepting any such warranty or additional liability.
        
           END OF TERMS AND CONDITIONS

**The build system for reproducible 3D prints.**

3D printing workflows are trapped in GUIs. Slicer settings get lost between
sessions, printer configs drift across machines, and there's no way to version,
diff, or review a print job. None of this is accessible to automation — or to
AI assistants.

estampo takes a different approach: define parts, slicer settings, and pipeline
stages in a single TOML file — text that's git-friendly, diffable, and
committable alongside your CAD files. Because the entire workflow is text,
it's naturally accessible to AI coding assistants, CI systems, and code review.
Same repo, same config → same G-code, locally or [in CI](#cicd-example).

> **Warning:** estampo is in active early development. We are moving fast and breaking things — config format, CLI flags, and Python APIs may change between minor versions without deprecation. Pin your version if stability matters to you.

> **Safety:** estampo generates G-code from your configuration but does not verify that settings are safe for your specific printer. Incorrect temperatures, speeds, or missing supports can damage your printer or create a fire hazard. Always review sliced output before sending to a printer. `estampo validate` checks config structure and setting names — it does not check print safety. **Use at your own risk.**

> **Note:** This project was previously called **fabprint**. If you have an existing install,
> run `pip install estampo` to upgrade — config files and credentials are migrated automatically.

Works with STL, STEP, and 3MF files, and pairs naturally with code-CAD tools like
[build123d](https://github.com/gumyr/build123d), [OpenSCAD](https://openscad.org),
and [cadquery](https://github.com/cadquery/cadquery).

```toml
# estampo.toml — a multi-part print with slicer overrides

[[parts]]
file = "enclosure_base.step"
orient = "flat"
filament = 1                    # AMS slot 1: PETG-CF

[[parts]]
file = "enclosure_lid.step"
orient = "upright"
filament = 1

[[parts]]
file = "button_cap.stl"
copies = 4
filament = 2                    # AMS slot 2: PLA

[slicer]
engine = "orca"
version = "2.3.1"               # pinned for reproducibility

[slicer.orca]
printer = "Bambu Lab P1S 0.4 nozzle"
process = "0.20mm Standard @BBL X1C"
filaments = ["Generic PETG-CF @base", "Generic PLA @base"]

[slicer.orca.overrides]
sparse_infill_density = "25%"
enable_support = 1
brim_type = "auto_brim"

[pipeline]
stages = ["load", "arrange", "plate", "slice", "gcode-info", "pack"]

[pack]
command = "bambox repack {sliced_3mf}"
output = "{sliced_3mf}"
```

```bash
estampo run        # arrange → slice → pack, one command
```

```
  Output → estampo_output/enclosure
✔ Loaded 3 parts
✔ Arranged 3 parts onto plate  (256×256mm)
✔ Plate exported → plate.3mf
✔ Preview exported → plate_preview.3mf
✔ Sliced with OrcaSlicer 2.3.1 in 48s
✔ Print time: 3h 42m, 24.6g filament
✔ Packed → plate_sliced.gcode.3mf
```

## What estampo does

![estampo demo](https://raw.githubusercontent.com/estampo/estampo/main/docs/recordings/demo.gif)

1. **Define** parts + settings in `estampo.toml`
2. **Arrange** — bin-packs models onto the build plate
3. **Slice** — using a pinned slicer version (via Docker) for identical G-code across machines
4. **Post-process** — run command stages (pack for Bambu, template resolution, etc.)

Everything is declared in a single TOML file. Lock the slicer version, pin the
profiles, and the output is reproducible on any machine or in CI.

![estampo pipeline](https://raw.githubusercontent.com/estampo/estampo/main/docs/images/pipeline.png)

### Why not just use OrcaSlicer CLI?

OrcaSlicer CLI is great for slicing a prepared plate. estampo builds a reproducible pipeline around it:

- **Arrangement** — bin-packs multiple STLs onto the build plate (OrcaSlicer CLI has no arrange step)
- **Multi-part filament mapping** — per-part filament slot assignment and paint color preservation, injected into the 3MF metadata
- **Reproducible builds** — pin slicer profiles into your repo + lock OrcaSlicer version in Docker = identical gcode on any machine
- **Partial execution** — `--until plate` to inspect layout, `--only slice` to re-slice, `--dry-run` to test everything
- **Command stages** — run external tools (e.g. `bambox pack`) as pipeline stages with variable substitution
- **Headless Docker slicing** — no GUI, no display server, works in CI, uses a specific OrcaSlicer version

### Why not just use CuraEngine CLI?

CuraEngine CLI (`CuraEngine slice -j definition.json -s KEY=VALUE -l model.stl -o output.gcode`) is powerful but requires assembling the full invocation yourself:

| What you need to do | CuraEngine CLI | estampo |
|---------------------|---------------|---------|
| Load printer definition | `-j printer.def.json` + `-d` search paths for inheritance | `printer = "Ultimaker 2"` in TOML |
| Set material/quality | Chain of `-j` files or `-s` overrides for every setting | `[slicer.cura.overrides]` in TOML |
| Arrange multiple parts | Not supported — manual positioning | Automatic bin-packing |
| Multi-extruder mapping | `-g -e0 -l a.stl -g -e1 -l b.stl` per mesh group | `filament = 1` per part |
| Reproducible builds | Track all definition JSONs yourself | `version = "5.12.0"` + Docker |
| Version control | Shell scripts + scattered JSON definitions | Single TOML file — git-diffable and reviewable |
| Run in CI | Install CuraEngine + definitions manually | `uses: estampo/estampo/action@v1` |
| Pack for Bambu printers | Separate manual step | `[pack]` command stage |

With CuraEngine CLI, your build config ends up spread across shell scripts, `-s` flag lists, and JSON definition files — hard to diff, review, or commit as a coherent unit. estampo replaces all of that with a single declarative TOML file: git-friendly, diffable, and accessible to AI assistants and code review.

### Works with AI assistants

GUI-based slicers require point-and-click interaction that AI assistants cannot
drive. estampo's text-based config is different — an AI assistant can read your
TOML, understand your print setup, suggest overrides, create CI workflows, and
validate the result, all without leaving the conversation.

We provide a ready-to-paste [AI setup prompt](docs/ai-setup-prompt.md) that
gives any AI assistant (Claude, ChatGPT, Copilot) enough context to add estampo
to a project from scratch — it scans the repo for model files, asks you a few
questions, and generates the config. This isn't an AI feature bolted on — it's
an architectural property of using text instead of a GUI.

## Best fit

estampo is best suited to:

- Hardware teams keeping CAD and manufacturing inputs in Git
- Engineers who want deterministic slicing in CI
- Teams using AI coding assistants to manage their build and print workflows
- Makers who want a declarative print workflow instead of slicer click-ops

If you mostly want interactive print setup in a GUI, use OrcaSlicer or Cura directly.

## Status

### Stable

- Declarative print config in `estampo.toml`
- Multi-part arrangement
- Docker-based slicing with pinned slicer versions (OrcaSlicer, CuraEngine)
- Slicing for any printer supported by OrcaSlicer or CuraEngine
- Profile pinning into your repository
- CI slicing and artifact generation
- Network print initiation via Bambu Cloud



### Experimental

- Bambu LAN printing
- Moonraker printing

## Quick start

**Prerequisites:** Python 3.11+ and [Docker](https://docs.docker.com/get-docker/). Docker is
central to estampo — it runs the slicer (OrcaSlicer or CuraEngine) in a container with a pinned
version so every machine produces identical G-code. A locally installed slicer can be used as a
fallback but is not recommended.

```bash
pip install estampo
# or, to install as an isolated CLI tool:
pipx install estampo
```

Generate a config with the interactive wizard, or dump a commented template:

```bash
estampo init                       # interactive wizard — discovers profiles and CAD files, creates TOML
estampo init --template            # dump a commented template
```

Or create `estampo.toml` by hand (see [full config reference](https://github.com/estampo/estampo/blob/main/docs/config.md)):

```toml
[pipeline]
stages = ["load", "arrange", "plate", "slice", "pack"]

[plate]
size = [256, 256]       # build plate dimensions in mm
padding = 5.0

[slicer]
engine = "orca"
version = "2.3.1"       # pin OrcaSlicer version for reproducibility

[slicer.orca]
printer = "Bambu Lab P1S 0.4 nozzle"
process = "0.20mm Standard @BBL X1C"

[slicer.orca.overrides]  # simple way to define print settings without editing JSON
sparse_infill_density = "30%"       # stronger infill
wall_loops = 3                       # extra wall strength
enable_support = 1
brim_type = "auto_brim"             # help adhesion
curr_bed_type = "Textured PEI Plate"

[[parts]]               # define multiple parts using STEP, STL or 3MF inputs
file = "frame.step"
rotate = [180, 0, 0]    # flip so mounting plate faces down

Run it (see [full CLI reference](https://github.com/estampo/estampo/blob/main/docs/cli.md)):

```bash
estampo run                   # arrange, slice and send to printer
estampo run --until slice     # stop after slicing
estampo run --dry-run         # full pipeline without sending to printer
```

The arrangement (`plate`) stage generates a `plate_preview.3mf` — open it in any 3MF viewer to check placement:

## Reproducibility

Pin profiles into your repo so builds are identical across machines:

```bash
estampo profiles pin          # copies slicer profiles into ./profiles/
git add profiles/              # commit to lock them
```

Combined with a pinned `version` in `[slicer]` (which locks the Docker image), the same config always produces the same gcode.

### CI/CD example

Automate slicing in GitHub Actions — push a commit, get G-code as a build artifact with print metrics on your PR:

```yaml
# .github/workflows/slice.yml
name: Slice
on: [push, pull_request]
jobs:
  slice:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v6
      - uses: estampo/estampo/action@v1
```

The action slices your model, uploads G-code as an artifact, and posts print time / filament stats as a PR comment. See [`action/README.md`](action/README.md) for all options.

## CLI overview

```bash
estampo init                        # interactive config wizard
estampo init --template             # dump commented TOML template
estampo init --workflow             # wizard + GitHub Actions workflow
estampo validate                    # check config for issues
estampo run                         # full pipeline
estampo run --until plate           # stop after plating
estampo run --only slice            # run just one stage
estampo run --dry-run               # everything except sending to printer
estampo profiles list               # list available slicer profiles
estampo profiles pin                # pin profiles for reproducible builds
```

## Printing

estampo is printer-agnostic — it produces sliced output but does not send files to printers. For Bambu Lab printers, use [bambox](https://github.com/estampo/bambox) as a command stage to pack and print. Run `bambox login` to set up credentials (`~/.config/bambox/credentials.toml`). See the [AI setup prompt](docs/ai-setup-prompt.md) for full examples.
