3D printing has transformed prototyping and production, but warping and failed first layers remain among the most frustrating issues—especially on parts with sharp corners. Whether you’re a hobbyist printing a triangular prism at home or a factory running large print farms, those sharp corners often lift, curl, or drag, ruining prints and wasting valuable time.Traditionally, many turn to brims for adhesion. But as we’ll see, brims are not only inefficient but also create new
