Predict the thermomechanical response of additive parts during the metal powder bed fusion and directed energy deposition manufacturing processes.
Use multiscale modeling to predict the thermal and mechanical response of parts and help reduce build failures.
Simulate full builds for both powder-fed and wire-fed DED processes with Netfabb local simulation.
Adaptive meshing and the physics-based, multiscale approach help keep processing time low and accuracy high. (video: 1:07 min.)
Automatically compensate geometries based on simulation results to achieve the desired shape when printed.
Small scale simulation
Generate PRM files based on chosen material and process parameters for increased accuracy.
Part scale simulation
Simulate powder bed fusion additive manufacturing processes to identify potential causes of build failures.
Capture interactions between parts and the distortion of the build plate.
Design appropriate heating cycles for post-processing by inputting the temperature vs. time curve of the desired process.
Identify possible build failures with powder bed processes that may cause equipment damage.
Predict support failure to aid in the design and placement of support structures.
Predict how metal additive manufacturing parts will deform to help reduce build failures.
Model conduction of energy into the loose powder for increased model accuracy.
Accurately calculate residual stresses and strains built up during the AM process to identify likely regions of failure.
Simulate the mechanical response of a deposited part after removal from the build plate to calculate the final distortion.
Apply multiscale modeling to predict regions of a build that get too hot or not hot enough (lack of fusion) during processing.
Since 2012, more than US$7.3M has been spent validating the Netfabb Simulation solver predictions by comparing with experimental results for hundreds of design cases and geometries.
America Makes, GE GRC, and United Technologies Research Center data shows improved accuracy with the explicit modeling of loose powder and the interaction between parts.

Validating moving-source model predictions show Netfabb Simulation is able to accurately calculate temperature and distortion measured during the powder bed fusion process. The final calculated distortion is within 5% error of the measurement.
