In stereolithography (SLA) and Digital Light Processing (DLP) 3D printing, a raft refers to a foundational structure printed before the primary object. Its purpose is to improve adhesion to the build platform and address potential warping issues. Imperfect or failed separation of this initial structure during the printing process can stem from a variety of factors influencing the successful completion of the printing task.
The proper formation and detachment of this support structure are crucial for several reasons. It ensures the printed object remains firmly secured to the build platform, preventing shifts or dislodgments during printing. The absence of such issues improves overall print accuracy and reduces the risk of print failures. Historically, the successful implementation of this base structure has played a significant role in broadening the range of printable materials and geometries, thereby advancing the capabilities of resin-based 3D printing.
