# Brim
|
||||
|
||||
Brim is a flat layer printed around the base of a model to help with adhesion to the print bed. It can be useful for models with small footprints or those that are prone to warping.

## Type
|
||||
|
||||
This controls the generation of the brim at outer and/or inner side of models.
|
||||
Auto means the brim width is analyzed and calculated automatically.
|
||||
Controls how the brim is generated on a model's outer and/or inner sides.
|
||||
|
||||
### Auto
|
||||
|
||||
The Auto brim feature computes an optimal brim width by evaluating material properties, part geometry, printing speed, and thermal characteristics.
|
||||
|
||||
- Model geometry
|
||||
- Uses the model's bounding box to determine dimensions.
|
||||
- Height-to-area ratio: `height/(width²*length)`.
|
||||
- Printing speed
|
||||
- Higher maximum printing speeds generally increase the recommended brim width.
|
||||
- Thermal length
|
||||
- Defined as the diagonal of the model's base.
|
||||
- Reference thermal lengths (material-specific):
|
||||
- ABS, PA-CF, PET-CF: 100
|
||||
- PC: 40
|
||||
- TPU: 1000
|
||||
- Material adhesion coefficient
|
||||
- Default: 1
|
||||
- PETG/PCTG: 2
|
||||
- TPU: 0.5
|
||||
|
||||
The computed brim width is capped at 20 mm and at 1.5× the thermal length. If the final width is under 5 mm and also less than 1.5× the thermal length, no brim will be generated (width = 0).
|
||||
|
||||
### Painted
|
||||
|
||||
Painted will generate a brim only on painted areas of the model in the Prepare tab.
|
||||
Generates a brim only on areas that have been painted  in the Prepare tab .
|
||||
|
||||
### Outer
|
||||
|
||||
Outer will generate a brim around the outer perimeter of the model.
|
||||
Easier to remove than inner brim but can affect the model's appearance if the brim is not removed cleanly.
|
||||
Creates a brim around the model's outer perimeter.
|
||||
Easier to remove than an inner brim, but may affect the model's appearance if not removed cleanly.
|
||||
|
||||

|
||||
|
||||
### Inner
|
||||
|
||||
Inner will generate a brim around the inner perimeter of the model.
|
||||
More difficult to remove than outer brim and may close the model's inner details, but can hide where the brim was removed.
|
||||
Creates a brim around inner perimeters.
|
||||
More difficult to remove and less effective than an outer brim and may obscure fine inner details, but it can hide the brim removal seam.
|
||||
|
||||

|
||||
|
||||
### Outer and Inner
|
||||
|
||||
Creates a brim around both the outer and inner perimeters of the model.
|
||||
This approach combines the **disadvantages** of both brim types, making it more difficult to remove while potentially obscuring fine details but improving overall adhesion.
|
||||
|
||||

|
||||
|
||||
> [!TIP]
|
||||
>> Consider using a [raft](support_settings_raft) on complex models/materials.
|
||||
|
||||
### Mouse Ears
|
||||
|
||||
Mouse ears are small extensions added to the brim to help with adhesion and prevent warping.
|
||||
Usually this ears are added in the corners of objects to provide additional support and affect the model's appearance less than a full brim.
|
||||
Mouse ears are small, local brim extensions (typically placed near corners and sharp features) that improve bed adhesion and reduce warping while using less material than a full brim.
|
||||
The geometry analysis routine selects candidate locations based on the configured angle threshold and detection radius.
|
||||
|
||||

|
||||
|
||||
#### Ear max angle
|
||||
|
||||
Maximum angle to let a brim ear appear.
|
||||
If set to 0, no brim will be created.
|
||||
If set to ~180, brim will be created on everything but straight sections.
|
||||
Angle threshold (degrees) used to decide where mouse ears may be placed:
|
||||
|
||||
- 0° — disabled; no mouse ears are generated.
|
||||
- Between 0° and 180° — ears are created at features with local angles sharper (smaller) than the threshold.
|
||||
- 180° — ears are allowed on almost any non-straight feature.
|
||||
|
||||
#### Ear detection radius
|
||||
|
||||
The geometry will be decimated before detecting sharp angles. This parameter indicates the minimum length of the deviation for the decimation.

|
||||
This parameter indicates the minimum length of the deviation for the decimation.
|
||||
0 to deactivate.
|
||||
|
||||
## Width
|
||||
|
||||
Distance from model to the outermost brim line.
|
||||
Distance between the model and the outermost brim line.
|
||||
Increasing this value widens the brim, which can improve adhesion but increases material usage.
|
||||
|
||||
## Brim-Object Gap
|
||||
|
||||
A gap between innermost brim line and object can make brim be removed more easily.
|
||||
Gap between the innermost brim line and the object.
|
||||
Increasing the gap makes the brim easier to remove but reduces its adhesion benefit; very large gaps may eliminate contact and negate the brim's purpose.
