Quick Summary

Support filament is a special 3D printing material used to support overhangs, bridges, and complex shapes during printing.

In FDM 3D printing, some models have parts that hang in the air. Without support, those areas may fail, droop, or print badly. Support filament helps hold those areas while the model is being printed.

Support filament is commonly used with multi-material 3D printers such as Bambu Lab printers with AMS or AMS Lite. Some support filaments can be removed by hand, while others can dissolve in water or special liquid.

Support filament is useful for cleaner prints, smoother bottom surfaces, and more complex 3D models.

3D printing is becoming more popular in Malaysia1. Many users start by printing simple models using PLA. After that, they may want to print more complex shapes, miniatures, mechanical parts, or models with difficult overhangs.

This is where support filament becomes useful.

Support filament is not usually used as the main model material. Instead, it is used as a temporary material to support the model during printing. Once the print is finished, the support material is removed.

This guide explains what support filament is, what it is used for, its advantages, limitations, and whether it is suitable for your 3D printing project.

What is Support Filament?

Support filament is a material used to support difficult parts of a 3D print.

When a model has overhangs, bridges, or floating sections, the printer may need support structures. These supports help the model keep its shape while printing.

In normal 3D printing, supports are usually printed using the same material as the model. For example, if the model is printed in PLA, the support is also printed in PLA.

With support filament, the support material is different from the main model material. This can make support removal easier and improve the surface quality of the final print.

What is Support Filament Used For?

Support filament is useful for models that are difficult to print without support.

Support filament can be used for:

  • Overhangs
  • Bridges
  • Complex models
  • Miniatures
  • Figurines
  • Mechanical parts
  • Product prototypes
  • Models with floating sections
  • Parts with smooth bottom surfaces
  • Prints that need easier support removal

Support filament is best for users who want cleaner results on complex prints.

Is Support Filament Good for Beginners?

Support filament can be useful for beginners, but it is usually not needed for very simple prints.

If you are printing basic models, keychains, name tags, toys, or simple parts, normal supports may be enough.

Support filament is more useful when you start printing complex models or when you want cleaner support areas.

To use support filament properly, you usually need a printer that supports multi-material printing. For example, Bambu Lab printers with AMS or AMS Lite can use different materials in one print.

For beginners, it is better to learn basic support settings first. After that, support filament can be useful for improving print quality.

Types of Support Filament

1. Breakaway Support Filament

Breakaway support filament is designed to be removed by hand after printing.

It does not dissolve in water. Instead, it separates more easily from the main model compared to normal support material.

Breakaway support is useful for users who want easier cleanup without using water or chemicals.

2. Water-Soluble Support Filament

Water-soluble support filament can dissolve in water.

This type of support is useful for complex models where support is hard to remove by hand.

A common example is PVA support filament. It is often used with PLA, but it must be kept very dry because it absorbs moisture easily.2

3. Special Support Interface Material

Some support filaments are used only for the support interface layer.

This means the main support structure can be printed using normal material, while only the layer touching the model uses support filament.

This can save material and reduce cost while still improving the print surface.

Advantages of Support Filament

1. Easier Support Removal

Support filament can make support removal easier compared to using the same material for both model and support.

2. Cleaner Print Surface

Support filament can improve the surface area where the support touches the model.

3. Good for Complex Models

Support filament is useful for models with difficult shapes, deep gaps, or complicated overhangs.

4. Less Risk of Breaking the Model

When support is easier to remove, there is less chance of damaging small details.

5. Better for Multi-Material Printing

Support filament works well with printers that can print more than one material in the same job.

Limitations of Support Filament

1. Needs a Compatible Printer

Support filament usually works best with multi-material printers.

2. Can Increase Print Time

Using support filament may increase print time because the printer needs to switch between materials.

3. Can Waste More Material

Multi-material printing can create extra purge waste when switching filament.

4. Needs Proper Settings

Support filament needs correct slicer settings to work well.

5. Some Types Must Be Kept Very Dry

Water-soluble support filament can absorb moisture easily. If the filament is wet, print quality may become poor.3

Choose normal support if you are printing simple models.

Choose support filament if you need easier removal and cleaner support surfaces.

Can Bambu Lab and Elegoo Use Support Filament?

Yes, some Bambu Lab and Elegoo FDM printers can use support filament, but it depends on the printer setup.

For Bambu Lab users, support filament is more useful when using AMS or AMS Lite because the printer can switch between model filament and support filament.

Support filament can be useful with printers such as:

  • Bambu Lab A1 with AMS Lite
  • Bambu Lab A1 mini with AMS Lite
  • Bambu Lab P1S with AMS
  • Bambu Lab X1 Carbon with AMS
  • Bambu Lab H series

For Elegoo users, support filament may be possible on FDM printers that support multi-material or multi-filament printing. Standard single-filament printers usually use normal support with the same material.

Elegoo Mars and Elegoo Saturn are resin printers, so they do not use FDM support filament.

Before using support filament, always check your printer compatibility and slicer settings.

How to Store Support Filament

Malaysia is hot and humid, so filament storage is very important.

Some support filaments, especially water-soluble types, absorb moisture very easily. Wet support filament can cause poor print quality, bubbling, stringing, weak support, and failed prints.4

To store support filament properly:

  • Keep it in a sealed bag
  • Use an airtight container
  • Add silica gel or desiccant
  • Keep it away from direct sunlight
  • Use a dry box if printing often
  • Use a filament dryer before printing if needed

Good storage helps support filament print cleaner and reduces failed prints.

Should You Buy Support Filament?

You should buy support filament if you often print complex models or want cleaner support removal.

Support filament is suitable for:

  • Complex models
  • Miniatures
  • Figurines
  • Mechanical parts
  • Product prototypes
  • Multi-material printing
  • Prints with difficult overhangs
  • Prints that need smooth supported surfaces
  • Users with Bambu Lab AMS or AMS Lite

If you only print simple models, normal support may be enough. If you print complex models often, support filament can help improve your results.
