Differences between TPE and TPU 3D printing

Differenza tra TPE e TPU

What is TPE in 3D printing

TPE (Thermoplastic Elastomer) is a thermoplastic material that combines the properties of plastics with those of elastomers. This material is prevalent in 3D printing because it offers excellent flexibility, tensile strength, and strong resistance to chemicals and weathering.

TPE is a very versatile material that can be used in various applications, such as toys, sporting goods, automotive components, moulds, prototypes, etc. It is also widely used for making gaskets, mouse and keyboard rubbers, and all parts requiring flexibility and durability.

TPE is an accessible material for 3D printing. It requires lower printing temperatures than many other thermoplastics. Once it has been printed, it is straightforward to machine and mould.
High-quality results can be achieved even with low-end 3D printing machines.

As we have already mentioned, one of the main advantages of TPE over other thermoplastics is its flexibility. TPE is very elastic and can be bent, stretched and compressed without breaking or damage.

TPE is also resistant to abrasion and chemicals, making it suitable for creating parts exposed to harsh conditions, such as car parts or sporting goods. It is also resistant to water, weather, and sunlight, making it an ideal material for creating outdoor items.

In addition, TPE is a straightforward material due to its flexibility. It can be easily cut, sealed, glued, and painted, making it highly versatile and suitable for many industrial and personal applications.

To conclude, regarding safety, TPE is a non-toxic and BPA-free material, which means it is safe for use with food and household products.

What is TPU in 3D printing

TPU (Thermoplastic Polyurethane) is a thermoplastic material used in 3D printing. TPU combines plastic and rubber, offering unique flexibility and strength. This material is versatile and used in many sectors, such as toys, fashion, medicine and engineering.

In 3D printing, TPU creates flexible parts, such as seals, lids, and hoses. Its flexibility allows for producing parts that can bend, compress, and deform without breaking or damaging them. In addition, TPU is highly resistant to abrasion and wear, making it suitable for use in harsh environments.

Another advantage of TPU in 3D printing is that it is easy to work with. TPU can be easily moulded into any desired shape, and its printing process is straightforward. Most 3D printers support TPU, and most 3D printing software can handle this material efficiently.

In addition, TPU is very reliable. This material does not warp easily, making it suitable for use in parts that must retain their shape for long periods. TPU is also resistant to water and moisture, making it ideal for wet or underwater environments.

Finally, TPU is available in many variants, each offering unique properties. Some TPU variants are more challenging, while others are softer. You can choose the TPU variant that best suits your projects and needs.

In summary, TPU is a highly versatile and reliable material for 3D printing. Its unique flexibility and strength make it suitable for many different uses, and its ease of processing makes it a popular choice for many 3D printing projects. If you are looking for a flexible and durable material for your next 3D printing project, TPU could be your solution.

So, what are the differences between the two materials?

All the differences between TPU and TPE in 3D printing

TPU and TPE are two types of materials used in the 3D printing process, and, at Fama3D, you can stamp using both, but there are many differences between them.

  • As mentioned above, TPU is a thermoplastic material that is abrasion—and water-resistant, as well as flexible and weather-resistant. This makes it suitable for creating objects that need to be flexible but also resistant to the elements. For example, TPU can create seals for windows or doors or even covers for electronic devices.
  • TPE, on the other hand, is a thermoplastic elastomer material that is more flexible than TPU. This makes it ideal for creating objects that need to be flexible and soft, such as toys, key rings or rings. In addition, TPE is also resistant to abrasion and impact, making it suitable for creating objects that need to resist wear and tear or damage.

Another difference between TPU and TPE is their temperature resistance. TPU is more temperature resistant than TPE and can withstand high temperatures without deforming or weakening. This makes it suitable for creating objects exposed to high temperatures, such as car parts or household appliances. Conversely, TPE is more sensitive to high temperatures and may deform or weaken if exposed to excessively high temperatures.

TPU and TPE also differ in their ease of printing. TPU can be printed more easily than TPE, with excellent thermal stability and lower viscosity. This makes TPU more suitable for creating complex objects that require greater precision and thermal stability during printing. TPE, conversely, can be more difficult to print due to its higher viscosity and lower thermal stability, but it still offers good print quality.

How to choose between TPU and TPE

The choice between TPU (thermoplastic polyurethane) and TPE (thermoplastic elastomer) in 3D printing is essential in determining the final product’s properties. As we have seen in previous paragraphs, both materials are very versatile and have high wear resistance, but there are some significant differences to consider.

The decision between TPU and TPE will depend on the project’s specific requirements. If you want a material that is more resistant to water and moisture, that is ageing and UV-resistant, then TPU might be the best choice. If, on the other hand, you want a material that is soft and comfortable to the touch, with low thermal resistance, then TPE might be the best choice.

Ultimately, the choice between TPU and TPE in 3D printing will depend on the project’s specific requirements. It is essential to carefully evaluate the properties of both materials and choose the one that best meets the project’s needs. A high-quality end product with superior wear properties can be obtained in both cases.
