3d Print Brim Vs Raft
“3d Print Brim Vs Raft” ~ bbaz


3D printing is a revolutionary technology that allows creating complex shapes and designs with ease. However, even with the advancement in the technology, the process of 3D printing can be challenging, especially for beginners. One of the challenges is getting the prints to stick properly to the bed without any warping or shifting. To overcome this problem, the 3D printing community has come up with two popular solutions- 3D print brim and raft. In this article, we will compare these two methods and see which one produces better results.

What is 3D Print Brim?

A brim is a thin layer of material that surrounds the base of your model, hence giving it a wider base and more surface area to adhere to the bed. Brims are generally used to ensure that the edges of the part don’t warp or curl upwards during the 3D printing process.

What is Raft?

A raft is a horizontal grid-like structure printed beneath your model. When you print your part onto a raft, the raft acts as a foundation for your part, keeping it grounded on the bed throughout the printing process. Rafts are most commonly used when printing parts that have small points of contact with the bed or that need extra support to avoid warping.

The Differences Between Brim and Raft

There are several differences between brim and raft. The main difference is that the brim only provides support to the bottom surface of your part, while a raft provides support to the entire bottom surface. Additionally, depending on the size of your part, brims tend to add less overall height than rafts. However, rafts tend to provide a more stable surface for your part, especially if you’re printing with low-quality filament or on an uncalibrated printer.

Which One Should You Choose?

Choosing between brim vs raft depends on the type of part you are going to print. If your part has a big base or multiple points of contact with the bed, then 3D print brim is a better choice. On the other hand, if your part has only a small surface area touching the bed, or the surface area is uneven, then raft would be a better option.

Advantages of Brim

Let’s discuss the advantages of 3D print brim below:

1. Enhanced Adhesion

A 3D print brim increases the surface area that comes in contact with the bed. This results in enhanced adhesion and better chances of successful printing. Brims are particularly useful when printing small, complex parts that require detail at the edge.

2. Saves Filament

When compared to rafts, brims use less filament as it is applied only to the bottom surface of your model. So, if you’re running low on filament, you should choose brim over raft.

3. Easy to Remove

Once you’ve finished printing your object, removing the brim is easy. All you need is a sharp blade, and you can peel the brim off gently without damaging the printed object.

4. Height doesn’t increase significantly

If you have designed a part with specific measurements or dimensions, you probably want to avoid any additional height added to the print. A brim is especially useful in this case since its height doesn’t affect the rest of your model.

Advantages of Raft

Let’s discuss the advantages of Raft below:

1. Enhances stability

If your printer bed is not leveled, prints can become more challenging. A raft provides an even surface for printing the first layer, which will create a stable foundation for the rest of the print. This ensures that the rest of the layers stay in place.

2. Allows Printing without Bed-Heating

Rafts allow you to print on an unheated bed. As rafts can stick to non-heated beds using the glue, you don’t need to worry about heating the bed or keeping the fan off.

3. Supports Overhangs and Bridges

Rafts are ideal for models with overhangs or bridges that can’t stand on their own while printing. The raft can provide support prevent sagging or warping during the print.

Comparison Table

Below is a comparison table between 3D print brim and raft for optimal results:

Features Brim Raft
Added Height Sparse Thick
Contact Surface Bottom Only Entire Part
Stability Less Stable than Raft More Stable than Brim
Supports Outlines Yes, but only on the bottom Yes, all over the model’s base
Extra Material Required Less than raft More than brim
Suitable for Small Bases Irregular/Odd Shaped Models


Choosing between brim and raft depends entirely on the part you want to print. While the brim creates less height, uses less material, and is straightforward to remove, rafts provide better stability and support all over the part’s surface area. You must consider your design’s specifics to determine which solution is optimal for your needs. Regardless of your choice, both solutions protect your prints from warping or shifting during the printing process.

Choose Wisely: 3D Print Brim Vs Raft for Optimal Results

Thank you for taking the time to read about the differences between 3D print brim versus raft. We hope that our discussion has helped you in making an informed decision about which option to choose for optimal results.

We understand that 3D printing can be a challenging task, but choosing the right support structure is essential to achieving the desired outcome. It is important to consider several factors when deciding between a brim or raft, including your printer type, print material, and model complexity.

Overall, we recommend that you experiment with both options and decide which one works best for you based on your specific printing needs. Remember to consider the benefits and drawbacks of each structure before making your final decision. With careful consideration and experimentation, you will be able to create high-quality 3D prints that meet your expectations. Thank you for reading and happy printing!

People Also Ask about Choose Wisely: 3D Print Brim Vs Raft for Optimal Results:

  1. What is a brim in 3D printing?
  2. A brim is a thin strip of material that is printed around the base of a 3D object to improve its adhesion to the build plate.

  3. What is a raft in 3D printing?
  4. A raft is a flat, solid layer of material that is printed beneath the 3D object itself. It helps to improve the adhesion of the object to the build plate, especially for objects with small or narrow bases.

  5. What are the advantages of using a brim?
    • Brim is easier to remove than a raft, which can sometimes leave behind unwanted marks or residue on the bottom of the object.
    • Brim uses less material and takes less time to print than a raft, making it a more efficient option for larger or more complex prints.
    • Brim provides good adhesion for most 3D objects, especially those with larger base areas that may not require the extra support of a raft.
  6. What are the advantages of using a raft?
    • Raft provides better adhesion for small or narrow-based objects, which may be prone to warping or peeling off the build plate without the extra support.
    • Raft helps to reduce the risk of the object becoming detached from the build plate during printing, which can cause the entire print job to fail.
    • Raft can help to improve the overall quality and accuracy of the finished object, especially for more intricate designs or those with overhangs or other challenging features.
  7. Which one should I use, brim or raft?
  8. The choice between brim and raft depends on the specific needs of your 3D printing project. If you are printing a larger object with a wide base area, a brim may provide sufficient adhesion without the need for a raft. However, if you are printing a smaller or narrow-based object, a raft can help to improve adhesion and reduce the risk of detachment during printing. It is always a good idea to experiment with both options and see which one works best for your specific application.
