Hey everyone, Stefan here. Ever wondered how to take a complex AI-generated model and bring it into the real world with 3D printing? In this tutorial, I’ll guide you through the entire process of preparing a 3D model for printing in Blender. We'll cover the essential steps to ensure a successful print, from making the model "watertight" and fixing non-manifold geometry to setting it up in a slicer. I'll explain why these technical checks are crucial and show you how to troubleshoot common issues. By the end of this video, you'll have a clean, optimized, and printable file ready for your 3D printer. --- 🎁 Win a FREE Hitem 3D Pro subscription!
