Motivation

This repository contains a module for creating automated workflows in the context of concrete additive manufacturing.

Workflow steps

• design definition (class Geometry)
• create mesh file (class Meshing)
• generate GCODE (class Gcode)
• perform FEM simulation (of print process or final printed structure) (class Simulation)

folder structure

• src/amworkflow: source code of the amworkflow package
• tests: pytest for general routines
• examples: example usecases
• usecases: new usecases

Conda

conda env create -f environment.yml

Installation

activate the environment if you did not:

conda env create -f environment.yml
conda activate amworkflow

to the root directory and then

doit install

Alternatively,

• you can do it manually: First clone the required lib:

  git clone https://github.com/tpaviot/pythonocc-utils.git

  Install it:

  pip install ./pythonocc-utils

  Last step, install amworkflow locally:

  pip install -e .

Then you are good to go.

Explore examples

Example workflows can be found in folder examples. Run them by calling the doit file in the subfolder.

cd examples/<example_name>
doit -f dodo_<example_name>.py

Toy

The toy example is a simple example to show the basic workflow steps.

Wall

The workflow is created for a curved wall element with geometrical parameters like length, thickness, width and height with different infill structures.

TrussArc

A arc with truss structure is given by a list of points defining the centerline. The design is created by those points and additional parameters like layer thickness and the gcode and simulation is set-up.

Umrandung

Workflow example creating gcode using a given csv file with the path points (all layers).

Create new usecase

By

doit -s new_case case_name="<name>"

a new folder under /usecases will be created with the name given containing a template workflow as basis for the new usecase.

Or copy the template.py file and use it as your new usecase.
