Flexfill TPU 98A | Fillamentum
Flexfill TPU 98A is a flexible filament made from thermoplastic polyurethane with a Shore A hardness of 98 (equivalent to 60 Shore D). This flexible filament's mechanical properties of high tear and tensile strength are appealing for the use of stressed parts.
It has high reversibility of deformation, as well as resistance to ozone, oils, greases, and aliphatic alcohols. The wear resistance of 3D printed parts from TPU 98A ensures their longevity. It's ideal for printing continuously moving parts or seals.

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.

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.

Frequently asked questions
Where is Fillamentum made?
Fillamentum is a Czech brand. Its filaments are exported to more than 62 countries around the world.
What is CPE HG100?
CPE is a copolyester related to PETG. It was developed for users who want more toughness than PETG while keeping easy printing with no warping.
Which Flexfill should I choose?
The number in the name is the Shore hardness: the lower the number, the softer and more elastic the part. Flexible filaments print best slowly, ideally with a direct-drive extruder.
