Top Applications of Thermoplastic Polyurethane (TPU) for 3D Printing Companies

The success of 3D printing design firms relies a lot on the specific materials used. Today, one of the most affordable and practical materials preferred for producing flexible parts using 3D printing is thermoplastic polyurethane or TPU. This article delves into the top thermoplastic polyurethane (TPU) applications for 3D printing companies.

What is thermoplastic polyurethane (TPU)?

Thermoplastic Polyurethane (TPU) is a type of engineering polymer material proven to have excellent performance. This material is known for its remarkable particularities, precisely its flexibility and resistance—the unique properties of the thermoplastic offer exciting possibilities for manufacturers, engineers, and designers. The material is developed to meet quality standards specific to the industry. Flexible TPU boasts exceptional mechanical properties and versatility. Using thermoplastic elastomer material, you can manufacture durable, robust performance parts with outstanding detail and surface quality.

You can use TPU material for various appliances, and its distinct traits make it an ideal choice for manufacturing companies. This material is handy for quickly 3D printing any part requiring flexible lattices or a rubber-like elasticity. As a synthetic plastic or elastomer material, TPU’s high resistance and flexibility shine out the most during additional processing, blending the properties of elastomers and thermoplastics. It can endure higher tensile and compressive forces than popular materials, including ABS and PLA.

The main reason for its hardness and softness variation is its chemical composition. The flexibility and hardness of the material change based on the proportion of the soft and hard segments. A more flexible 3D printed part is also possible due to a lower filling quantity. It affects the final parts’ transparency, adhesion, or softness to the touch of the details. The TPU material also provides excellent resistance to all oils and greases.

Characteristics and production of TPU

Even though most people are familiar with or have heard of TPU filaments, you can find them in resin or powder form. As for these polymers’ properties, they offer many benefits, such as their resistance to wear, cut, abrasion, and high impact. Their layer cohesion is also relatively high, resulting in outstanding mechanical homogeneity of the produced parts while making them isotropic simultaneously.

But it’s still important to consider some of the limitations of this particular material. For starters, TPU doesn’t adapt well to hot settings. It’s a noticeable factor because they cannot endure high temperatures even with such a massive working range. The print settings must also vary according to the 3D machine and technology. Unlike another form of flexible filament, TPE, it’s easier to print TPU and better at retaining its elastic properties at lower temperatures.

The TPU material is also more grease, oil, and abrasion-resistant. With its conformability and flexibility, TPU filament sets itself apart from other stiffer thermoplastics. It also has no issues with delamination and deformation during manufacturing 3D printing services.

Advantages of using thermoplastic polyurethane (TPU) for 3D printing

The combination of the fantastic benefits of TPU and 3D printing can open new doors of opportunities for your company. Use this powerful flexibility in your products and manufacturing process alike.

Develop more flexible prototypes

You can enjoy the perks of an efficient prototyping method with additive manufacturing. You have to develop a 3D model of the project and have it 3D printed, but this time, you don’t need molding. The technique is ideal for creating several iterations or variations of a single product. The best thing about additive manufacturing is its speed and ability to produce prototypes in a snap of a finger. It’s an obvious benefit when developing a project and running a business.

Remember that time is money, particularly as far as prototyping design firms are concerned. Testing your new design solutions faster allows you to quickly tweak your design and proceed to your final product’s manufacturing process. With the help of advanced materials like TPU, your prototypes can take on new properties, and most importantly, they can become more functional and solid.

Design freedom

3D printing is the ideal manufacturing strategy to experience the real essence of freedom of design. Creating intricate designs and complex geometries that can never be manufactured using traditional techniques is always a significant advantage. Developing an attractive structural design makes it possible to 3D print parts for different applications, including the footwear and automotive industries.

Using TPU for 3D printing allows functions with additional flexibility according to the thickness and other zones. This also makes it possible to manufacture lighter parts that are easily integrated with the environments where the standard is at stake, such as aeronautics or automotive.

Mass customization

Mass customization can become an easy process while using design for additive manufacturing services. If other manufacturing techniques like injection molding make customization expensive and complicated, 3D printing technology makes it cost-effective and straightforward. The key in several sectors is to create adapted products. Using TPU for 3D printing is the ideal solution if you are developing made-to-measure flexible parts. Your company can gain a competitive edge if you provide your clients with custom-made products and experience.

Production

While 3D printing is considered a cost-effective method if you only need to manufacture small quantities, this state-of-the-art technology makes using rapid prototyping firms for serial production more appealing and practical. With the rise of new technical materials like TPU, production is becoming one of the primary applications of today’s additive manufacturing process. Using 3D printing to produce your projects is a great way to take a step back and reconsider your supply chain. You can have flexible parts on demand and quickly use a digital inventory.

Additive manufacturing eliminates the need to keep your adjustable anymore; instead, you can choose and decide on the exact size of your batch. It’s also possible to get one part or more whenever necessary. TPU is also recommended for developing flexible and complex lattice structures that can be used to create shoe parts like orthopedic midsoles. You can also use the exciting facilities to lessen the weight of the products, which is critical in many sectors.
