ModelValidator

class pyslm.geometry.ModelValidator

Bases: object

ModelValidator takes the data structures in pyslm.geometry such as a list of Layer and Model and validates their input for consistency when utilised together to form a machine build file prior to exporting using libSLM. Basic consistency checks include:

• Validating each BuildStyle used in each Model, including individual laser parameters

• References to a correct BuildStyle via its (bid) for each LayerGeometry included

• References to a correct Model via its (mid) for each LayerGeometry included

• Ensure there are unique BuildStyle entries for each Model included

The key function that can be called is validateBuild(), which is recommended to be called before attempting to export the layer and model information to a libSLM machine build file translator. Additional sub-functions are also available for checking specific objects used to construct the build-file.

Methods Summary

validateBuild(models, layers)	Validates an AM Build which compromises of a list of models and layers
validateBuildStyle(bstyle)	Validates a single BuildStyle ensuring that its individual parameters are not malformed.
validateModel(model)	Validates a single Model ensuring that its individual BuildStyle are not malformed.

Methods Documentation

static validateBuild(models, layers)

Validates an AM Build which compromises of a list of models and layers

Parameters:

• models (List[Model]) – A list of Models used in the build

• layers (List[Layer]) – A list of Layers used in the build

Raises:

Exception – When an invalid BuildStyle is provided

Return type:

bool

Returns:

True if the structures are coherent and valid

static validateBuildStyle(bstyle)

Validates a single BuildStyle ensuring that its individual parameters are not malformed.

Parameters:

bstyle (BuildStyle) – The BuildStyle to validate

Return type:

bool

Returns:

True if the structure is coherent and valid

Raises:

Exception – When an invalid BuildStyle is provided

static validateModel(model)

Validates a single Model ensuring that its individual BuildStyle are not malformed.

Parameters:

model (Model) – The Model to validate

Return type:

bool

Returns:

True if the structure of the Model is coherent and valid

Raises:

Exception – When an invalid BuildStyle is provided
