Abstract

Nowadays additive manufacturing technology is rapidly developing. Therefore questions of using materials, software and equipment for additive manufacturing are actual.

The goal of this work is development of program components for work preparation of additive manufacturing (PCWPAM) differing from the state-of-the-art by the possibility of functional enhancing and adaptation to new production objectives.

To achieve the assigned objectives we solved the following problems:

  1. The simulation system kernel allowing hierarchical assembly design is developed.

  2. Geometric models in mesh view import/export with adequate accuracy is provided.

  3. Space assembling set of tools for simulation of printing units workspace is created.

  4. Mathematical methods for model geometry validation and generation of layer by layer discrete model representation with adequate accuracy is developed.

  5. Process modeler and numeric engineering analysis means typical for selective high-temperature additive manufacturing processes are created.

  6. Software environment for G-code generation is prepared.

As a result of this work we obtained software components for process design with the following performance capabilities:

  1. models import from CAD systems in STL format;

  2. binding of models in equipment working chamber;

  3. saving chamber binding in internal PCWPAM format and export of models with allowance for spatial transformations in STL format in printing unit system of coordinates;

  4. generation of layer by layer models representation;

  5. a discrete representation development for equipment chamber;

  6. G-Code generation;

  7. temperature calculation for the models bind in working chamber.

We carried out a validation of generated G-code instructions with extraneous software (Polygon for Designer). The validation demonstrated correctness of methodologies and algorithms included into PCWPAM.

According to generated G-code we carried out the «control» printing of a part without any extraneous software. It proved the efficiency of the developed software components for additive manufacturing process design.

The similarity of additive manufacturing operating procedures allows speaking about applicability of the developed software components for other technologies of layer-by-layer synthesis either.
