In the rapidly evolving landscape of 3D printing, we're continuously exploring materials and methods that push the boundaries of design and functionality. Today, we're proud to share our latest breakthrough: printing a jet engine bracket using BASF PPGF-30 filament.

The Power of Generative Design

Before we dive into the printing process, let's take a moment to appreciate the marvel that is generative design. This cutting-edge technology allows us to input design goals and parameters into Autodesk's Fusion360 software, which then generates the most efficient shapes and structures. The result? A piece that's optimized for strength, weight, and material usage — perfect for the high-stakes world of aerospace engineering.

Choosing the Model: An Engine Bracket Built for the Skies

Setting the Stage: Precision Printing with BASF PPGF-30

For this task, we turned to BASF's PPGF-30, a glass fiber-reinforced polypropylene known for its strength and resistance to fatigue — but also for being notoriously tricky to print due to warping issues. We faced this challenge head-on, confidently setting our nozzle temperature to a steady 260 degrees Celsius and our bed temperature to a firm 80 degrees Celsius.

The Fan Dance: Cooling with Care

Our fan speeds played a delicate balancing act, minimum at 30% and maximum to 80%, ensuring each layer of PPGF-30 cooled sufficiently to maintain its shape without compromising layer adhesion.

The Results: A Testament to Tenacity

The final print stood as a testament to tenacity and precision. With a 35% infill — considered high for such applications — we anticipated challenges. Yet, as the print concluded, it was clear that our Filasophia adhesive had once again worked wonders. The bracket adhered to the print plate throughout the process, free from warping and ready for real-world application.

Reflecting on the Journey

This print was more than just a successful job; it was a demonstration of how far we've come in 3D printing. Other adhesives might shy away from the challenge of PPGF, but ours rose to the occasion, proving that with the right settings and a bit of innovation, even the most demanding materials can be tamed.
