Bamboo ASA

Bambu ASA is a highly durable material that offers exceptional UV, weather, mechanical and thermal resistance. Its unique combination of properties makes it an ideal material for printing outdoor models (plant signs, mailboxes, weather pennants, etc.) as well as structural parts exposed to long-term and demanding outdoor conditions.

Extraordinary weather and UV resistance

Bambu ASA offers exceptional resistance to UV radiation, oxidation and ageing, providing effective protection against breakage and colour deterioration in long-term outdoor use.

Tough and durable

Suitable for outdoor applications and general structural requirements thanks to the material's toughness and high impact strength.

Better temperature resistance

Compared to regular PETG or ABS, Bambu ASA retains its shape even at temperatures up to 100°C.

Frequently Asked Questions

1. What is the difference between ABS and ASA?

ABS	ASA
Composition: acrylonitrile – butadiene – styrene	Composition: acrylonitrile – styrene – acrylate

ASA is a modified version of ABS, which contains an additional acrylate component that improves the material's weather resistance and UV resistance.

ASA retains the impact strength and processing properties of ABS, but has better resistance to fading, yellowing, and degradation when exposed to sunlight. Both materials can emit a pungent and unpleasant odor during printing, but the odor from ASA is noticeably milder than that from ABS.

2. What is the difference in applications for ABS and ASA?
ASA is ideal for outdoor applications – such as exterior car parts, signs and outdoor equipment – ​​thanks to its improved weather resistance and color stability. ABS is a versatile material with excellent mechanical properties and is typically used for indoor applications.

3. What are the similarities between ABS and ASA?
Both materials have good impact resistance and high tensile strength with almost the same level of strength, toughness and stiffness. Both ABS and ASA can emit a pungent and unpleasant odor during printing, and both are prone to warping when printing large and/or high infill density models, and require a closed printer cabinet for this type of printing.

Printing tips

• A strong, unpleasant odor may be emitted during printing. Make sure the printer is in a well-ventilated area.

• Drying: 80°C for 8 hours. Store the filament in a dry environment after use. If the material has absorbed moisture, it should be dried before printing. Please see Filament drying instructions on WIKI for more details.

• ASA tends to warp when printing large-sized models and/or with high infill density.
To avoid warping:

1. It is not recommended to print too large models or with very high infill density.

2. Use a printer with an enclosure, and make sure the build plate has glue on it before you start printing.

3. Reduce print speed and increase bed temperature. See Common Print Quality Issues and Solutions on WIKI for more details.
