To promote optimal bed adhesion, this layer should be thickest (i.e. The former is the first layer of the raft to be printed. Layer Thickness: There are three distinct layer thickness settings when it comes to rafts: base layer thickness, middle thickness, and top layer thickness. That being said, you may want to adjust some settings for the best outcome. Most slicer software programs, like Cura and Simplif圓D, have raft integrations built in, so you don’t have to design them yourself. (Image: Simplif圓) Slicer Settings for Rafts Rafts are 3D printed underneath the part, acting as a platform that anchors the part to the build platform. A raft can create a flat, level base for your part to be printed on. Another scenario in which a 3D printed raft has benefits is if your build platform is damaged or warped. In this case, using a raft can stabilize the object as it is printed. Rafts can also be used in cases where the 3D model has an unbalanced structure–for example, a part with a heavier top and smaller footprint. Using a raft if you don’t have a heated build platform can help lessen the chances of warpage. Higher temperature thermoplastic filaments like ABS are also more likely to warp without a printed heat bed. First and foremost, if you are 3D printing with ABS filament-a material prone to warping-a raft can improve adhesion by ensuring your print’s first layer sticks to the top layer of the raft. Rafts can be very effective in certain circumstances. ![]() Rafts are a technique used by makers to improve first layer adhesion and stabilize parts throughout the printing process. Poor adhesion can lead to warped and defective parts. In FDM 3D printing, first layer adhesion to the build platform is vital to ensuring that your 3D prints turn out well. A raft usually consists of a grid-like 3D printed structure, which sits underneath and extends beyond the borders of the first layer of the 3D model, acting as a base. 3D Printing Raft What is a Raft?Ī raft is essentially a 3D printed platform on which parts are printed. In the following article, we illustrate what each 3D printed feature is and when and how to use it for the optimal result. If used correctly, rafts, brims, and skirts each have their benefits and can make the difference between a successful or failed print. If you’re struggling with proper bed adhesion and warping when 3D printing, there are some tried and true techniques for improving print results-especially for ABS and higher temperature materials.
