Validate Your 3D Parts Before Printing

Updated: Mar 20, 2023

Markforged Simulation Software

Markforged has a range of composite fibre, metal and industrial high-temperature 3D printers combined with a smart software platform that makes it easy to solve tough manufacturing problems.

Markforged machines are used heavily by Engineering and Manufacturing firms to 3D print parts for R&D, design development, production aids, jigs & fixtures to bespoke, obsolete and end-use parts.

Markforged have just released a new software, Simulation.

Why Simulation software?

Simulation software takes the guesswork out of the performance of the finished 3D printed part, by validating part strength and optimising parameters before printing.

Where total confidence is required in the strength and performance of the part, Simulation removes the need for repeat design-print-break test cycles, external part analysis and the "over-building" of parts - adding in too much reinforcing fibre or excess infill settings.

What will Simulation deliver?

Simulation is an automated way to validate part performance, through the Markforged print preparation software platform, Eiger.

Simulation enables the user to validate a part prior to print, and select an optimised print setting (with or without fibre), based on the unique required performance parameters.

  • Remove need for post-part analysis: Virtually test parts prior to printing, based on specific performance and load parameters to ensure the 3D printed parts will have the strength required for demanding industrial applications.

  • Reduce test cycles: Simulation is integrated into Eiger, so validating and optimising parts easily becomes part of the streamlined process for additive manufacturing, speeding up workflows and delivering the required part faster, removing the need for multiple repeat iteration test cycles

  • Reduce costs of 3D printed parts: Selecting from the optimised print settings generated by Simulation ensures the correct amounts of material and continuous fibres (if required) are used. This avoids over-built parts and wasted material, making the 3D printed part even more cost-effective.

Why do Engineers love Simulation software?

We asked our CREAT3d engineers why is a simulation software so useful? Watch our short video (with the sound on!) to hear what they had to say.

In short, our engineers had a few key stand-out factors of using Markforged Simulation software;

1) Removes risk of adopting 3D printed parts in-house. The software provides the engineer with the assurance they can print the parts first time, and they will deliver on performance

2) Easy to use; straight-forward to apply loadings so it's quick to set-up, saving valuable time!

3) Increases confidence in the use of fibre; helps to use more fibre in the correct places, at the correct quantities, saving on costs but also enhancing part performance

How does Simulation work?

Simulation enables the Markforged user to validate part strength and stiffness. The software suggests optimised print configurations to reduce print time or material costs.

When Simulation is active in Eiger. Once the part is loaded,

1. Press Simulation - identify anchor and load surfaces, enter values for loads, Factor of Safety and Max Deflection (stiffness)

2. Press Validate - run a simulation to assess whether the current part settings meet or fail the required performance parameters

3. Press Optimise - if further optimisation is required, engage Simulation to generate multiple simulations to generate alternative print configurations. Select from range of print settings, according to your priorities of faster print time, or less material, whilst ensuring end part performance

4. Press Print - print the original part settings, or after applying one of the optimised settings.
