Bambu Lab - ASA -

Bambu ASA

Bambu ASA is characterised by exceptional resistance to UV radiation, weathering, mechanical stress and high temperatures. This unique combination of properties makes it perfect for 3D printing outdoor models such as plant labels, letterboxes, weather vanes, etc., as well as structural components that must withstand demanding outdoor conditions over the long term.

Exceptional weather and UV resistance

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

Robust and durable

Thanks to its toughness and high impact resistance, it is ideally suited for outdoor use and regular structural demands.

Better temperature resistance

Unlike conventional PETG or ABS, Bambu ASA retains its shape even at temperatures of 100°C.

Frequently Asked Questions

What is the difference between ABS and ASA?

ASA is a modified variant of ABS that contains an additional acrylate component, which improves weather resistance and UV resistance. Despite the improvements in weather resistance and UV resistance, ASA retains the impact strength and processability of ABS. It also offers greater resistance to fading, yellowing and degradation caused by sunlight. Both materials can emit a sharp and unpleasant odour during the printing process, although the odour from ASA is noticeably less intense than that of ABS.

What is the difference between ABS and ASA applications?

Thanks to its improved weather resistance and colour stability, ASA is ideally suited for outdoor use, particularly for external applications such as automotive exterior parts, signage and outdoor equipment. ABS, on the other hand, is a versatile material with excellent mechanical properties and is frequently used for indoor applications.

What are the similarities between ABS and ASA?

In terms of physical and mechanical properties, both ABS and ASA exhibit good impact resistance and high tensile strength. The values for strength, toughness and stiffness are almost comparable. During the printing process, both ABS and ASA can emit a strong and unpleasant odour, particularly with large-format models or models with high infill density. In such cases, they are prone to warping and require the use of an enclosed printer.

RFID for smart printing

Experience the future of 3D printing with the Bambu Lab AMS (Automatic Material System). All key printing parameters are stored on a handy RFID chip. The 3D printer can read the print parameters automatically. No more tedious adjustments – simply load your filament and start the print job. Enjoy convenient and time-saving operation without complicated manual settings.
