Now that we\u2019ve seen what Eiger<\/a> Simulation is, what do we do with our part once it\u2019s simulated?<\/p>\n

In this article, we\u2019ll walk step by step through how to use simulation to optimize a design before even performing the first physical tests. Just like in Part 1, we\u2019ll rely on a concrete example.<\/p>\n

Here, we\u2019ve modeled a hook that must withstand a 40 N load with a safety factor of 2.5.<\/p>\n

\"Eiger<\/a><\/h2>\n

1. Initial Analysis<\/h2>\n

Once the part is imported into Eiger, we set the load case and run the simulation.<\/p>\n

\"Eiger<\/a><\/p>\n

\"Eiger<\/a><\/p>\n

Result: our part is expected to fail with a safety factor of 0.43. It clearly needs reinforcement.<\/p>\n

2. Orientation<\/h2>\n

Is my part oriented in the most effective way for my application?<\/p>\n

Keep in mind that a 3D printed part is generally weaker in the Z direction. Printed layers are more prone to delaminating than tearing.<\/p>\n

In our case, the hook is subjected to bending in the Y direction around the X axis. The maximum stress is therefore normal to the XY plane, along the Z axis, the weakest direction. Let\u2019s try reorienting the part.<\/p>\n

\"Eiger<\/a><\/p>\n

After running a new simulation:<\/p>\n

\"Eiger<\/a><\/p>\n

The safety factor jumps from 0.43 to 1.49. Reorienting the part made it more than three times stronger.<\/p>\n

However, we\u2019re still below our target of 2.5, so we need deeper refinement.<\/p>\n

3. Design Improvements<\/h2>\n

Can the design be improved?<\/p>\n

In general, a design can always be optimized depending on time and resources. To strengthen a part, one of the most effective approaches is to reduce stress concentrations and increase load-bearing surfaces.<\/p>\n

For instance, adding fillets is a simple and efficient solution.<\/p>\n

After exploring several configurations, we found an optimized version that preserves similar costs while increasing strength.<\/p>\n

\"Eiger<\/a><\/p>\n

\"Eiger<\/a><\/p>\n

By adding basic fillets, we increased the safety factor by 46% (from 1.49 to 2.18) with no extra material cost, print time, or weight.<\/p>\n

Still below our target of 2.5, time to push further with Eiger\u2019s automatic optimization.<\/p>\n

4. Optimization in Eiger<\/h2>\n

To launch optimization, simply select the corresponding option after running the simulation.<\/p>\n

\"Eiger<\/a><\/p>\n

Eiger will test several configurations in the background, without using your local resources. Perfect moment for a coffee break while your part optimizes.<\/p>\n

After some time, Eiger provides multiple configuration suggestions.<\/p>\n

\"Eiger<\/a><\/p>\n

In our example, adding concentric carbon fiber increased the safety factor to 2.76,\u00a0surpassing our 2.5 target, with about 30% higher cost.<\/p>\n

There’s also the existence of an Onyx-only configuration reaches a safety factor of 2.55 for just 5% more cost.<\/p>\n

Here’s the solution offered by Eiger:<\/p>\n

\"Eiger<\/a><\/p>\n

The fiber-reinforced version shows fibers placed strategically around the highest-stress zones.<\/p>\n

Optimized, Verified, and Ready to Print.<\/h2>\n

Without printing a single part, we already have a reliable understanding of how the hook will behave under load. We can now print it and test it under real conditions.<\/p>\n

Thanks to Eiger<\/a>\u2019s simulation and optimization features, we save both time and material resources.<\/p>\n
