Features

3D printing software from design to manufacture

Netfabb® software includes efficient build preparation capabilities alongside tools for optimizing designs for additive manufacturing, simulating metal additive processes, and planning for CNC post-processing. 

Build preparation

  • Import, analyze, and repair models

    Import models from a variety of CAD formats and use repair tools to quickly correct errors. (video: 2:30 min.)

  • Modify models for production

    Make your models production ready by adjusting wall thicknesses, smoothing rough areas, and more. (video: 2:32 min.)

  • Configurable build supports

    Identify areas that require support and use semi-automated tools to generate support structures. (video: 2:17 min.)

  • Mesh to CAD conversion

    Convert organic, free-form mesh files to boundary representation models and make them available in CAD in STEP, SAT, or IGES format.

  • 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.

  • Advanced toolpaths

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

  • Automation

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

Design optimization for additive manufacturing

  • Internal lattice structures

    Create lightweight parts with performance characteristics specific to your application.

  • Topology optimization

    Generate forms that are optimized for stiffness and weight, based on the loads and constraints of the part.

  • Integrated performance analysis

    Test how your optimized designs will perform using built-in Autodesk® Nastran® simulation.

  • Optimization engine

    Automatically verify and optimize lattice and skin elements to meet load requirements and reduce weight.

  • Selective space structures (3S)

    Fill solid volumes with standard or custom structures to create unique material properties for your part.

Machine integration

  • Integrated print engines

    Select from the most popular additive manufacturing machines to configure the Netfabb workspace to your process.

  • Solutions for machine manufacturers

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

Netfabb Simulation capabilities

Predict the thermomechanical response of additive parts during the metal powder bed fusion and directed energy deposition manufacturing processes.

  • Metal powder bed fusion

    Use multiscale modeling to predict the thermal and mechanical response of parts and help reduce build failures.

  • Directed energy deposition

    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: 1:07 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 vs. 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 AM 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 modeling 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

  • Graph plotting out simulated distortion results

    Part/powder interaction

    Experimental data show improved accuracy with the explicit modeling 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.
