With metal powder bed fusion (MPBF) and direct energy deposition (DED), use multiscale modelling to simulate the thermal and mechanical response of parts and help reduce build failures

Core capabilities of Netfabb

Build preparation

Import, analyse and repair models

Import models from a variety of CAD formats and use repair tools to quickly correct errors. (video: 3 min.)

Modify models for production

Make your models production ready by adjusting wall thicknesses, smoothing rough areas and more. (video: 2:26 min.)

Configurable build supports

Identify areas that require support and use semi-automated tools to generate support structures. (video: 1:47 min.)

Automatic packing

Use 2D and 3D packing algorithms to optimally place parts within the build volume.

Report generation

Create custom reports that include critical information for manufacturing and quoting.

Additive toolpaths

Develop build strategies and define toolpath parameters for maximum surface quality, part density and speed.


Automate common preparation tasks including import, analysis, repair, packing, slicing, and tool pathing.

Solutions for machine manufacturers

Netfabb works with a range of OEMs to create integrated printing experiences configured for specific machines.

Netfabb Local Simulation

Predict the thermomechanical response of additive parts during the MPBF and DED manufacturing processes.

Simulation features


Use multiscale modelling 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.

Fast, predictive simulation

Adaptive meshing and the physics-based, multiscale approach help keep processing time low and accuracy high. (video: 1:06 min.)

Small-scale simulation

Generate PRM files based on chosen material and process parameters for increased accuracy.

Part-scale simulation

Simulate the additive manufacturing process for powder bed fusion to identify potential causes of build failures.

Simulate the entire build plate

Capture interactions between parts and the distortion of the build plate.

Simulate stress relief

Design appropriate heat treatment cycles by inputting the temperature versus time curve of the desired process.

Detect recoater interference

Identify possible build failures with powder bed processes that may cause equipment damage.

Avoid support failure

Predict support failure to aid in the design and placement of support structures.

Predict part distortion

Predict how metal additive manufacturing parts will deform to help reduce build failures.

Account for part/powder interaction

Model the conduction of energy into the loose powder to increase your model’s accuracy.

Calculate residual stresses

Accurately calculate residual stresses and strains built up during the additive manufacturing process to identify likely regions of failure.

Simulate response after wire-cutting

Simulate the mechanical response of a deposited part after removal from the build plate to calculate the final distortion.

Predict hot spots and lack of fusion

Apply multiscale modelling to predict regions of a build that get too hot or not hot enough during processing.

Compensate for distortion

Automatically compensate geometries based on simulation results to achieve the desired shape when printed.

Simulation validation and research


Part/powder interaction

Experimental data shows improved accuracy with the explicit modelling of loose powder and the interaction between parts.


Support failure prediction

Netfabb simulates the delamination of the part from the region where the support structure on a component experienced failure.


Moving source simulation

Netfabb Simulation accurately calculates temperature and distortion during the powder bed fusion process to within 5% error of the measurement.
