Dual-Laser LPBF in slow motion

Synchronized 💥 Dual-Laser 💥 LPBF processing @ 400.000 fps ➡️ Unlock full potential of #MetalAM for voxel-graded materials 🚀 on #MaterialsMonday

Why just use the LPBF process for the production of complex parts, when you can also realize function-optimized and voxel-based tuning of your material structure and resulting mechanical properties ⁉️ Just turn the subsequent laser on and off for a local in-situ heat treatment 💡

✔️ An adjustable increase in as-printed microhardness of up to 15% from 411 HV up to 471 HV
✔️ A consistent melt pool structure due to elaborated exposure strategy
✔️ New possibilities to produce functionally graded material structures by synchronized dual-laser LPBF processing

All results are based on the processing our exclusive high-performance maraging hot-work tool steel Specialis®.
