ExPolaris by ExLatticeLPBF thermal simulation

builds up.
Before you print.
Fast, scan-path-aware thermal simulation for metal laser powder bed fusion (LPBF). Move from quick screening to detailed full-build analysis before committing machine time and material.

Simulation description
This simulation shows heat spreading and cooling as the laser scans five consecutive layers. The left view looks down on the part; the right shows a vertical cross-section through its internal features. Brighter colors indicate warmer regions. Both views advance together.

How it works
From build data to thermal histories.
Bring the planned manufacturing inputs. Explore the calculated response.
Provide your build inputs
Supply supported toolpaths, part layout, laser settings, material properties, and preheat or boundary conditions.
Simulate with ExPolaris
Model how the laser's energy input and scan sequence shape temperature throughout the build.
Review the thermal results
Inspect temperature histories by region and layer, and compare the response to different build settings.

Broader applications of ExPolaris thermal results
When combined with established models and validation for your application, thermal results can help investigate porosity, residual stress, distortion, and microstructure, and contribute evidence to part qualification.
Discuss your applicationCommon technical questions
Before we start.
What should we bring to a technical demo?
Your machine, material, build configuration, and thermal question are enough to begin. We can then confirm suitable input formats and any data needed for an evaluation.
Will it work with our machine and material?
We support EOS and other LPBF systems, with a growing range of materials and toolpath formats. Share your machine model, material, and file format so we can confirm the right setup for your build.
How long will our simulation take?
Choose a coarser resolution for quick screening or a finer resolution for detailed analysis. Runtime varies with build size, resolution, and GPU hardware; we can walk through a representative case in your demo.
How can we become an early tester?
Contact us with your machine, material, and toolpath challenge. We'll discuss whether the optimization prototype suits your use case and agree on an evaluation scope. The optimization prototype's supported configurations and performance are still being evaluated.
Can it support our software or OEM workflow?
We can review toolpath access, batch evaluation, and data-exchange requirements. Available interfaces and deployment options must be confirmed for your platform.
