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 skirt brim and raft?

Brims are often used to hold down the edges of your part, which can prevent warping and help with bed adhesion. The Brim may be a preferred option to the raft (which also helps with adhesion), as the brim can typically be printed much faster and uses far less filament.

Which is better raft or brim?

Rafts create better adhesion, for example, than brims because they are placed underneath the printed object. It helps the material stick together, thereby improving adhesion. Of course, the downside to using rafts is that they are more difficult to separate from the printed object than brims.

What is Wave Bonding 3D printing?

Wave Bonding Feature: For the very first layer, anchor points are created approximately every 5mm to ensure the model sticks to the print surface. We recommend using this feature for large prints to prevent the first layer from warping/peeling.

Why do my 3D prints keep falling?

Poorly Leveled Print Bed or First Layer Settings If the print bed and the first layer settings are not properly adjusted and calibrated, the 3D print can fail or fall over. If the footprint of the first layer is not large enough to balance or stabilize the print, it will detach and fall over.

Are there any problems with 3D printing a raft?

One of the most persistent problems that 3D printing professional encounter is warping or curling. Fortunately, the 3D printing community has come up with various ways to counter this problem. One of these is building your print with a raft.

Why is printing a raft a common practice?

To understand why printing a raft has become a common practice, we need to understand the mechanism that results in the warping or curling of a print. The fundamental principle that makes Fused Deposition Modeling (FDM) printing possible is the ability of thermoplastics to conform to different shapes when heated to their melting temperature.

Do you have to use ABS when printing a raft?

A convenient dichotomy to exhibit this is between PLA and ABS: while printing with a raft is rarely done with PLA, it’s a measure that is more common when using ABS. Even with other measures to prevent warping, such as applying ABS glue on a heated bed, printing with a raft is still highly recommended.

When to use a raft for bed adhesion?

When you are experiencing poor bed adhesion The biggest advantage of using a raft is the large surface area it provides for the build to stick to the build platform. The bottom layers of a raft are commonly printed thick and slow, resulting in a very strong solid mesh.
