Accelerating Additive Manufacturing Innovation with Oak Ridge National Laboratory and Rescale
SimCamp 2025 brought together industry leaders and national lab researchers at ORNL’s Manufacturing Demonstration Facility (MDF) for an immersive workshop on additive manufacturing simulation. Supported by Rescale, the event featured technical talks and hands-on tutorials led by ORNL code developers, giving participants direct access to newly published MDF codes on the Rescale platform.
Throughout the workshop, attendees worked with cutting-edge models for predicting microstructures, analyzing melt pool behavior, and simulating part-scale heat transfer. This hands-on experience allowed industrial partners to test these advanced tools while providing valuable feedback to ORNL’s R&D team, helping align research efforts with real-world manufacturing challenges.

Adamantine
Adamantine is a thermomechanical simulation code written in C++ for additive manufacturing, built on deal.II, ArborX, Trilinos, and Kokkos. It models the evolution of solid, liquid, and powder states during processing and leverages experimental data via ensemble Kalman filtering to improve accuracy.
AdditiveFOAM
AdditiveFOAM is a simulation framework for transport phenomena in additive manufacturing, built on OpenFOAM. It solves multiphysics problems with finite volume methods, simulates detailed geometries and scan paths, and couples with ExaCA for process–structure predictions.
ExaCA
ExaCA is a C++ code for predicting as-solidified grain structures from thermal history data. Built with MPI and Kokkos for scalable, portable performance on CPUs and GPUs, it models nucleation, solidification dynamics, and dendrite geometry. Coupling with process models enables efficient simulations with billions of cells.
Myna
Myna is a Python framework that links real-world process data to additive manufacturing simulations. It automates simulation setup using measured data, aligns models and as-built parts in the same coordinate system, and supports tools including AdditiveFOAM, ExaCA, 3DThesis, and Mist, with data from the MDF’s Peregrine system.
3D Thesis
3DThesis is a C++ code for rapid simulation of transient temperature fields in additive manufacturing. Using an analytical solution for a moving Gaussian heat source, it independently evaluates space-time points, enabling efficient melt pool and solidification analysis.
