Specifications

Essentium is a company renowned for its R&D work, achieving to be at the forefront of additive manufacturing. Among the products it develops, the wide variety of filaments aimed at industrial FDM 3D printing stands out, as well as some with very specific applications, managing to provide solutions of all kinds to meet the needs of sectors such as aeronautics, automotive or the energy sector.

Within its wide range of FDM 3D printing materials is the TPU 95A-LF filament, a TPU-based filament with a composition that reduces its friction with other materials.

TPU (Thermoplastic Polyurethane) is a thermoplastic, more specifically a linear elastomer polymer belonging to the polyurethane family. One of the characteristics that differentiate TPU from other thermoplastics is its elongation at break. While other thermoplastics have up to 100 % elongation at break, TPU has up to 500 % elongation at break. Within TPU, different hardness ranges can be found. In FDM 3D printing, hardness is usually indicated by the Shore A or Shore D scales, which perfectly cover the hardness ranges of thermoplastics for AM.

With its TPU base and Shore 95A hardness, TPU 95A-LF filament is a medium-hard filament with good flexibility and has the impact resistance and chemical resistance of the base material. Its outstanding properties are as follows:

Chemical resistance
Abrasion resistance
High elongation at break percentage
High tensile strength
Excellent impact resistance
Resistant to oils

Low friction surface

Despite its flexibility, it is a relatively easy-to-print filament that, thanks to its printing characteristics, can be processed on almost any desktop FDM 3D printer on the market, although it is recommended that you have a direct extruder. This filament has a low-friction surface that facilitates and guarantees a smooth material feed during the printing process. Due to its properties, the TPU 95A-LF filament is very useful for applications in sectors such as automotive, construction, consumer goods manufacturing or the industrial sector, allowing the production of a wide range of products:

Rapid prototyping: TPU 95A-LF enables rapid prototyping to bring ideas to life with great immediacy, allowing you to materialise, test and present different models or improvements on an initial design until the desired result is achieved.
End-use parts: Thanks to its mechanical and chemical properties, TPU 95A-LF filament allows 3D printing of end-use parts and components quickly, accurately and with good repeatability, enabling in some cases the production of parts that would be very complex using other manufacturing methods or technologies.

Specific applications for TPU 95A-LF filament include the manufacture of anti-vibration mounts, protective housings, vibration isolation for automobiles, hoses and flexible ducting, sports protective equipment, insoles and shoe soles, among others.

If you have a 3D printing machine with multiple printheads, it is possible to produce complex parts using TPU 95A-LF and a support material, or to produce parts with rigid and flexible zones. This offers enormous possibilities and design freedom.

Due to its properties and its composition developed specifically for AM, TPU 95A-LF is an ideal solution for companies that require the manufacture of parts with medium-hardness flexible parts with excellent impact resistance and good chemical resistance.

TPU 95A-LF filament has been developed with the aim of offering a versatile and easy-to-print flexible material. This is achieved thanks to its low-friction surface, which ensures a smooth material feed throughout the 3D printing process.

When processing this material, a printing temperature of 230-250°C and a bed temperature of 50-80°C is recommended. This filament does not require the use of 3D printing equipment with a heated chamber.

The recommended printing speed is between 20 and 40 mm/s, being recommended to use a lower printing speed for the first layer (between 15 and 20 mm/s). It is not necessary to work with a layer fan, although up to 20 % can be used. On the other hand, to obtain an optimum result, it is advisable to work with a flow rate of 1.03.

The TPU 95A-LF filament has a high adhesion to the base and between layers, although, if necessary, it can be improved by using a specific adhesive for flexible materials such as Magigoo Flex.

To obtain optimum printing results with this filament, it should be taken into account that it is a hygroscopic material, so it should be kept free of moisture. For this purpose, it is advisable to use an F3 Safe case, which allows both storing the material and keeping it free of humidity during the printing process. If the material is exposed to moisture, it is recommended to dry it with a filament dryer such as PrintDry Pro. Once dry, it is recommended to store it in a container such as the PrintDry Smart Filament Container.
