How to store filaments
Humidity and UV light can decrease the filament quality and weaken its mechanical properties. We strongly recommend storing open filaments in a dry and dark place. You can find a complete guide on how to properly store your filament here
Where to throw print fails and supports?
We kindly ask our customers to cope with plastic waste responsibly. Failed prints, support material, rafts, or brims should be liquidated according to the local guidelines. Paradoxically, in most cases, it is better to throw this waste in the regular trash can, as most of the material waste created in 3D printing is not identified, which causes more problems than benefits in the waste sorting facilities.
TPU for AMS | Bambu Lab
Bambu Lab TPU for AMS redefines TPU printing with enhanced performance and seamless AMS integration. It feeds reliably through the AMS, opening up vibrant multicolour projects with flexible material.
With a Shore hardness of 68D it offers impressive toughness while minimising stringing, combining the ease of PLA printing with the flexibility and durability TPU is known for. Wall loops and infill density let you tune how elastic the finished part is.
- Shore hardness 68D
- Prints from the AMS – multicolour flexible prints
- Minimal stringing, PLA-like ease of printing
- Tough and durable
- Diameter 1.75 mm ± 0.05 mm, RFID spool
Recommended settings: nozzle 220–240 °C, bed 30–35 °C (Textured or Smooth PEI Plate with glue), cooling fan on, printing speed up to 250 mm/s. Dry at 70 °C for 8 h before printing.
General information about TPU :
TPU or thermoplastic polyurethane is a common flexible material often confused with TPE. TPU is a type of TPE. Recently, “TPU”, both as a term and as a material, has been gaining popularity over “TPE”. In today’s 3D printing scene, most flexible offerings are TPU-based materials, with TPE having fallen largely out of favor due to difficulties faced while printing. There are different versions of TPU material but in the main, it can be classed into two types. Firstly known as Polyether Polyurethane and secondly Polyester Polyurethane. Both have different characteristics that can be suited to a specific need.
Printability of TPU filament
TPU filaments are claimed to have a better printability than TPE filaments. Still, you need to take similar preventive measures as with TPE. The best results when printing with TPU will be seen when printing with a slow and consistent speed. As TPU has a high level of elasticity, it can mean that any sudden changes can cause a loss of control in the print speed. Fast print speeds can result in the filament compressing and will lead to a jam. Concluding: slow and steady is the best approach to take when printing TPU. The recommended printing speed is 5-40 mm/s (higher for harder filaments, lower for softer materials).
TPU mechanical and thermal properties
In certain blends, it can become very soft, but TPU material offers many benefits and features. 3D printed parts with TPU are durable and have the ability to withstand ambient temperatures of up to 80 degrees Celsius. TPU is very elastic ranging from 600 to 700%. It has increased chemical resistance to oils and greases. It also has an excellent interlayer adhesion and no curling or delamination during the 3D printing process.

Bambu Lab filaments are the original materials developed together with Bambu Lab 3D printers such as the A1, P1 and X1 series. They are for anyone who wants plug-and-print results: every spool carries an RFID tag, so the AMS recognises the material and colour and loads the right print profile automatically. JustCreate3D keeps Bambu Lab filaments in stock in its warehouse in Senec, Slovakia, and dispatches orders quickly.
Bambu Lab is a consumer-tech company founded in 2020 in Shenzhen, China, by a team of engineers from the robotics and drone industry. Its X1, P1, A1 and H2 series made fast, reliable multi-colour 3D printing accessible to everyone.
Bambu Lab filaments at JustCreate3D
- PLA Basic – the easiest material to start with and the everyday workhorse, designed for high-speed printing.
- PETG Basic and PETG HF – tougher than PLA; PETG HF is optimised for high-speed printing, with less oozing and a uniform matte finish.
- PETG-CF – PETG reinforced with carbon fibre for stiffer functional parts.
- TPU 95A HF and TPU for AMS – flexible TPU; TPU for AMS is made to feed reliably through the AMS for multi-colour flexible prints.
Which Bambu Lab filament to choose?
Starting out on an A1 or A1 mini? Begin with PLA Basic. For parts that need more toughness or heat resistance, move to PETG Basic or PETG HF. Choose PETG-CF for stiff technical parts and print it with a hardened steel nozzle, because carbon fibre is abrasive. For flexible parts, pick TPU – and if you want to print it from the AMS, take TPU for AMS.
Frequently asked questions
Will the AMS recognise the filament automatically?
Yes. Bambu Lab spools carry an RFID tag that tells the AMS the exact material and colour, so the matching print profile is loaded without manual setup.
Can I print TPU from the AMS?
Standard flexible filaments are usually fed outside the AMS. Bambu Lab TPU for AMS was developed to feed reliably through the AMS, which makes multi-colour flexible prints possible.
Do I need to dry Bambu Lab filament?
Store spools dry. If a filament has absorbed moisture, dry it before printing – the recommended drying temperature and time for each material are listed in its product description.
