Bambu ASA
Bambu ASA is an extremely durable material that features outstanding resistance to UV rays, weathering, mechanical and thermal influences. Its unique combination of properties makes it an ideal material for printing exterior patterns (plant signs, mailboxes, weathervanes, etc.) and structural parts that require long-term exposure to challenging outdoor conditions.
Exceptional weather and UV resistance
Bambu ASA offers outstanding resistance to UV rays, oxidation and ageing, providing effective protection against breakage and colour deterioration in long-term outdoor use.
Robust and durable
It is suitable for outdoor applications and regular structural requirements due to its robustness and high impact strength.
Better temperature resistance
Compared to conventional PETG or ABS, Bambu ASA can retain its shape even at temperatures of 100°C.
Frequently Asked Questions
1. What is the difference between ABS and ASA?
| ABS | ASA | |
| Composition: | acrylonitrile – butadiene – styrene | acrylonitrile – styrenes – acrylates |
ASA is a modified version of ABS that contains an additional acrylate component that improves its adaptability to weather conditions and UV resistance.
ASA retains the impact resistance and workability of ABS while providing better resistance to fading, yellowing and degradation from exposure to sunlight. Both types can emit pungent and unpleasant odors during printing, However, the pungent odour of ASA is significantly milder than that of ABS.
2. What is the difference in applications between ABS and ASA?
Due to its increased weather resistance and color stability, ASA is ideal for outdoor applications such as vehicle exteriors, signage and outdoor equipment. ABS is a versatile material with excellent mechanical properties that is commonly used for indoor applications.
3. What are the similarities between ABS and ASA?
In terms of physical and mechanical properties, both types are characterised by good impact resistance and high tensile strength, with almost equal levels of strength, toughness and toughness. Both ABS and ASA can give off pungent and unpleasant odours during printing and the same tendency to distort and require a closed printer when printing large size models and/or high fill densities.
