Supports help you print overhangs. You can quickly configure your support settings for one of a few different types of support structures.

See also Manual Supports.

standard support

Breakaway Standard supports are "normal" supports. A simple support pillar that just ends with a small gap before your model’s overhangs start to print so that you can remove the support column later


Breakaway - Sawtooth supports are an all-new way to generate support pillars. At the top of the support pillar will be a series of "teeth" that generate a perforated edge for your model’s overhangs to print on top of. This gives better support while still being easy to remove.


Breakaway - Scanline supports generate typical support pillars topped with a denser interface section. The extra density of this interface section helps support your model’s overhangs, improving surface quality.


Soluable supports eliminates any gaps between your support structures and your model. While soluable support pillars will be extremely difficult to remove by hand, they can simply be dissolved away, leaving a perfect surface finish.

Maximum unsupported overhang angle

This defines how steep your printer can print before it needs support materials underneath the overhang.


Lower numbers will not filter out shallow angles, meaning more overhangs will be supported.


Higher numbers will filter out shallower angles, meaning fewer overhangs will be supported.

Support Fill (per Iteration)

This controls how dense the supports will be printed. This does not include the interface area, where the support column actually touches your print. Try to keep supports as sparse as possible while still maintaining their strength.


Lower numbers will generate sparser supports, which will be weaker but take less time to print. Printing supports too sparse can lead to them falling over or not adequately supporting the interface layers above them.


Higher numbers will generate denser supports, which will be stronger but take longer and use more material to print. The denser the support pillars, the better they’ll support the interface layers above them and the less likely they’ll be to accidentally fall over.

Support Angles per Layer

This controls the number of different angles supports will be printed at on each layer. More angles ensure that each support pillar is more stable.


Lower numbers will generate support tracks in fewer directions on each layer.


Higher numbers will generate support tracks in more directions on each layer, improving stability.

This will print a fully solid layer below any support column that is touching the build plate.


Un-checking this box will not generate the base for the support columns.


Checking this box generates a base for any support columns touching the build plate. This helps keep them anchored, but takes extra time and materials.

Interface Layers

This controls the number of special layers of support that touch the model itself. These interface layers can be customized separately from the rest of the support column.


Lower numbers will generate fewer interface layers.


Higher numbers will generate more interface layers.

Z Gap Between Support and Model

This controls the size of the gap between the tops of support columns (the interface layers) and the model they’re supporting. The gap is measured in multiples of your default layer height. Tuning this gap is extremely important: too much of a gap will leave room for your overhangs to droop and they won’t look good. Too little of a gap will cause your supports to bond to your print, making them very hard to remove.


Smaller numbers will decrease the gap between print and support, making the print look better but making supports harder to remove.


Larger numbers will increase the gap between print and support, making the supports easier to remove but making the print look worse.

Perimeter Interface Strategy

This controls the algorithm that is used to generate supports.

Scanline is the normal support algorithm

MA Edge is an experimental algorithm that provides supports only where a model really needs them. NOTE: Complex geometry will almost certainly create unprintable supports with overlapping tracks.

Solid Fill Interface Strategy

Strategy to use when printing a support underneath a solid-filled part of your print.

Scanline is the normal support algorithm

Support Interface Fill

This controls the density of the top-most region of a support pillar. This is the portion of the support that actually touches your model. It is important for this area to be denser so that it supports your model well.


Lower numbers will generate sparser interface layers, meaning supports will have less surface area for your model’s overhangs to rest on. This can lead to worse surface quality on your print.


Higher numbers will generate denser interface layers, meaning supports will have more surface area for your model’s overhangs to rest on. This will produce better surface quality.

Tooth Spacing

This spaces out each tooth of the sawtooth interface layers on a given line of teeth. (This is along the low point of each tooth)


Lower numbers bring sawteeth closer together. This improves adhesion between your supports and your model, but can make it harder to separate them.


Higher numbers will space out the sawteeth. This will make it easier to remove the support pillars, but will also provide less support for your model’s overhangs.

Tooth Height

This adjust how tall each of the sawteeth are (in the Z-axis)


Lower numbers shrink the height of each sawtooth. This gives less perforation between the support interface your model, but is easier to print with a flat nozzle or lower layer height.


Higher numbers raise the height of each sawtooth. This increases the size of each tooth, and is better when printing with thicker layers or pointier nozzles.

Tooth Width

This adjust how long each of the sawteeth are (in the high point of the tooth)


Lower numbers shorten each dot’s peak. Shorter teeth are ideal for pointier nozzles.


Higher numbers lengthen each dot’s peak. Wider teeth are better for flatter nozzles, since they don’t come into contact with the dots as much on the downstroke.

Tooth Extrusion Multiplier

How much to adjust extrusion when printing sawteeth

Lower numbers make sawteeth smaller and weaker. Try lowering the extrusion multiplier if sawteeth are sticking to your model too much or blobbing a lot.

Higher umbers make saw teeth fatter and bigger. Try increasing the extrusion multiplier if your HotEnd isn’t keeping consistent extrusion when printing saw teeth.

Interface XY Expansion

This controls how far beyond the edges of your print supports will be created. The extra expansion can help ensure that your model is fully supported. Raising this expansion too much will simply waste filament and time, however.


Lower numbers will generate supports closer to the edges (ie not extending as far beyond them) of your print.


Higher numbers will generate supports further beyond the edges of the areas of your print that they’re supporting.

Support XY Gap

This offsets support pillars from the sides of your model so that they don’t accidentally bond to your print. A large gap can lead to unsupported areas in some models.


Smaller numbers will decrease the gap between print and support, making supports fully reach the areas they need to, but also making them more likely to fuse to the side of your model.


Larger numbers will increase the horizontal gap between print and support, making supports less likely to touch your model where they shouldn’t, but also potentially leaving parts of the model unsupported
