Ester-based TPU in cases the oil and greases resistance is more relevant. The crystalline or pseudo crystalline areas act as physical cross-links, which account for the high elasticity level of TPU, whereas the flexible chains will impart the elongation characteristics to the polymer. This is mainly due to the composition of hard and soft segments. This means that it is resistant to water, heat, oil, and certain chemicals. We may now conclude this article by stating that the invention of the best flexible filaments has been a great boon for the 3D printing community. This is where TPU or thermoplastic polyurethane comes in. After all, TPE is a non-specific term for a broad range of flexible polymers. $310.00. Let’s now look at the outstanding properties of this flexible material. TPU is ideal for end use parts, functional prototypes, concept models and custom components. Flexible Thermoplastic Urethanes (TPU) filaments within the 3D printing industry range between Shore A 60 – 90 and are classified as being ultra-flexible to semi-flexible. It is possible to use this material with any properly equipped FDM 3D printer.

C’est un filament qui est résistant aux graisses, huiles et à l’abrasion. TPE vs TPU filament. It's also possible to use in big equipments vertical injection or extrusion machines to directly print, without the intermediate step of filament extrusion or powder preparation, just choosing the adequate TPU granulates (pellets). Flexible materials have a property called Shore hardness, which determines the flexibility or hardness of a material. There may be some confusion between TPE and another flexible filament, TPU, or thermoplastic polyurethane. The thermoplastic polyurethane cases are light. TPU manufacturers usually advise against printing this flexible filament at a printing speed of 30 millimeters per second. Consequently, TPU scrap can be reprocessed. TPU works well if you are looking for flexibility, very similar to PETG, a polymer we featured in a previous article. Its durability also extends to being able to withstand a variety of elements. For example, if you print a thin model, you may be able to bend it. Chez AliExpress, rien ne nous rend plus fier que la lecture des retours positifs de notre chère clientèle, c’est pourquoi nous nous engageons à leur offrir le meilleur. TPU is a form of block copolymer (contains soft and hard segments). So no matter how many times you pick up your phone, rub the case while putting it inside your pockets, TPU will last for years. But this does not mean that TPU is devoid of any … They will not make your cell phone bulky. Its Shore hardness means that it is resistant to abrasion, everyday wear and tear, and high impact. TPU is ideal for end use parts, functional prototypes, concept models and custom components. Pour réaliser notre plastique flexible nous utilisons du TPU ( du Polyurethane thermoplastique) spécialement conçu pour la technologie de Frittage Sélectif par Laser ( SLS). The polarity of the hard pieces creates a strong attraction between them, which causes a high degree of aggregation and order in this phase, forming crystalline or pseudo crystalline areas located in a soft and flexible matrix. TPU can even be colored through a number of processes. TPU is a thermoplastic elastomer with low Shore Hardness 85-95A .
