What is the purpose of a raft during 3D printing?
A 3D printed raft is basically a throwaway horizontal surface that sits under your object. It’s made up of a predetermined number of layers, with a specific infill percentage, that extends a specific distance away from the sides of your object. The primary purpose of a raft is to help with bed adhesion.
What is the difference between a brim and a raft in 3D printing?
Like a raft, a brim is a substrate used for 3D printing. … The difference between them, however, is that rafts go underneath the printed object, whereas brims go around the printed object. A brim can best be described as a flat and horizontal expansion of the printed object’s initial layer.
How many raft layers are there?
Ideally, a raft bottom of two layers is good for adhesion. Raft Top Layer will mate with the first layer of the print. Since this layer will determine the surface finish of the bottom layer of the print, it’s recommended that you use at least two to three layers to achieve a smooth surface.
How can I print without a raft?
To 3D print without a raft, you should use a good enclosure to reduce drafts and keep a stable printing temperature. Having a good print orientation with the flatter surface on the print bed is ideal. You should use a good adhesive such as hairspray or a glue stick to help 3D prints stick to the bed.
How do you increase plate adhesion?
Use a standard white glue stick directly on the build surface. Glue sticks will also help in terms of adhesion to the build surface. All that should be needed is a thin layer coating the entire space your object will be printed on. If more glue is necessary, apply at your own discretion.
How do you make a raft run smoother?
