From CAD model to 3D print

3D Printing Software – Support for Design and Additive Manufacturing

3D printing software is used in the stage between design and additive manufacturing. Our CAD tools— IRONCAD, Rhinoceros Design Data Manager—prepare models that can then be processed in printer-specific systems while preserving geometry, tolerances, and material data.

What is 3D printing software?

3D printing software is the collective term for the programs that handle the transition from digital design to physical printing. The software is responsible for preparing the geometry, checking wall thicknesses, and exporting models in formats such as STL, OBJ, VRML, and 3MF —formats that the printer’s own software then interprets.

It’s not just about the printer itself, but about the entire chain of tools that ensures a CAD model can be converted into a correctly printed object. From the initial concept in a 3D CAD program to the finished prototype or mass-produced part—every step requires precision and the right software.

Why is preparation in CAD so important?

A 3D model that looks good on screen isn’t necessarily ready for printing. Common problems include open surfaces, walls that are too thin, and incorrect normals. By working in a professional CAD system such as IRONCAD or Rhinoceros , you can analyze and correct these issues before sending the file to the printer’s slicer software.

  • Geometric check - verify that the model has closed volumes and correct surface normals to ensure error-free printing.
  • Wall Thickness Analysis - Identify areas that are too thin for the selected material or printing method.
  • Format Export - Export to STL, 3MF, or OBJ with control over mesh resolution and tolerances.

Tools for creating 3D models for printing

We work with CAD and PLM solutions that enable the creation, verification, and organization of
3D models for additive manufacturing.

Design Data Manager Logo

Design Data Manager

Design Data Manager serves as a database and version control system for models and metadata. By managing the entire workflow from CAD files to print formats, DDM ensures DDM the correct version is always used in production.

  • Revision & Version Control
  • Integration with IRONCAD other CAD software
  • Traceability throughout the entire process

CAD design and integration with 3D printing software

The design work in IRONCAD Rhinoceros both 3D modeling and surface definition.
These programs export complete models to 3D printing software without losing any shape or structural information.

1. CAD Design

Create your 3D model in IRONCAD Rhinoceros parametric, direct, or free-form modeling, depending on the component’s complexity.

2. Analysis & Validation

Check wall thicknesses, enclosed volumes, and surface normals. Identify and resolve potential issues before exporting.

3. Export file

Export the model to STL, 3MF, or OBJ with controlled mesh resolution. Manage versions using Design Data Manager.

4. Printing & Prototyping

Send the file to the printer's slicing software for slicing and printing. From rapid prototyping to mass-produced parts.

Modeling methods for 3D printing

We have been providing design, training, and software support since 1988.
This experience gives us a deep understanding of how CAD models are used in real-world production environments.
