3D Printing Materials for Pet Orthotics: Part 1 – The Role of HP

In veterinary care, it’s essential to keep up with the latest innovations. At WIMBA, our focus is on delivering top-quality orthotics for pets to aid in their comfort and recovery. A key component of our approach is the advanced HP Multi Jet Fusion (MJF) technology. In this article, we’ll explore how MJF technology is transforming the way we design and produce WIMBA orthotics, providing significant advantages for both veterinary professionals and pet owners.

Introduction to HP MJF 3D Printing Technology

HP Multi Jet Fusion (MJF) 3D printing technology is a significant advancement in the field of additive manufacturing. HP’s powder bed additive manufacturing technology provides new capabilities, enabling us to create parts that are not only lighter and more functional but also highly complex. Despite their complexity, these parts are simpler to finish and assemble.

3D Printing Materials for Pet Orthotics

In addition to leveraging Multi Jet Fusion (MJF) technology, WIMBA orthotics are crafted using a combination of advanced materials, each selected for its unique properties to ensure optimal performance and comfort for pets. 

Here’s a closer look at the materials used:

• HP High Reusability PA 11
• HP High Reusability PA 12:
• BASF Forward AMs Ultrasint® TPU01

HP 3D High Reusability PA 11

HP 3D High Reusability PA 11 is a polyamide (PA) material designed for use in HP’s Multi Jet Fusion (MJF) 3D printing process. PA 11 is a thermoplastic polymer renowned for its strength, resistance to chemicals, and ability to withstand high temperatures. It is utilized to create durable and flexible functional parts of orthotics. This material ensures that 3D-printed parts meet high-quality standards and provides excellent performance in terms of durability, detail, and precision.

• Application: PA 11 is utilized to produce the rigid frame of WIMBA orthotics.
• Main benefits: Known for its excellent mechanical properties, HP High Reusability PA 11 offers robust stability. It is durable, ensuring that the orthotics can withstand the physical demands of pets. 

HP 3D High Reusability PA 12

HP 3D High Reusability PA 12 is a durable thermoplastic that creates high-density components with well-balanced properties and robust structures. Also referred to as Nylon PA12, this material is known for its ability to produce parts with balanced performance characteristics and significant strength.

• Application: PA 12 is used for the tokens and hinge caps in WIMBA orthotics.
• Main benefits: This material is crucial for the functional aspects of the orthotics, such as adjusting the range of motion and resistance. The high wear resistance and strength of PA 12 make it ideal for components that undergo frequent movement and stress. 

The Role of BASF Ultrasint® TPU01

While the article’s focus is on HP High Reusability PA 11 and PA 12, it’s important to note that BASF Ultrasint® TPU01 plays a crucial role in enhancing the comfort and functionality of our orthotics. This soft, elastic material is used for the inserts, providing cushioned support that adapts to the pet’s anatomy for a perfect fit. In our next blog we will explore the benefits and applications of BASF Ultrasint® TPU01 in more detail.

Benefits of Multi Jet Fusion (MJF) for WIMBA Orthotics

Multi Jet Fusion (MJF) technology is a cornerstone of WIMBA’s approach to designing and manufacturing high-quality orthotics for pets. Its advanced capabilities offer a range of benefits that enhance the performance, customization, and sustainability of our orthotic devices. 

Here’s a closer look at how MJF technology contributes to the exceptional quality of WIMBA orthotics.

Design Freedom and Functional Excellence

One of the most compelling advantages of Multi Jet Fusion (MJF) technology is its exceptional design freedom. This advanced printing method allows WIMBA to create orthotic components that are both durable and lightweight. MJF enables the production of complex geometries and highly functional parts that seamlessly integrate into the final orthotic. The result is a product that not only meets high standards of performance but also boasts an aesthetically pleasing finish. This design capability ensures that each orthotic not only functions optimally but also looks and feels like a premium, well-crafted device, perfectly tailored to the pet’s anatomy.

Customization and Scalability

By integrating HP’s MJF 3D printing technology with WIMBA’s automated design and WimbaSCAN processes, we are able to produce over 1,000 devices each week—an achievement not feasible with other manufacturing methods. Each orthotic device can be precisely tailored to address the unique needs of each pet, providing a perfect fit and optimal support. This approach is essential for enhancing the recovery experience, as it ensures that every orthotic is adapted to the individual anatomy and condition of the pet. 

Sustainability and Efficiency

MJF technology significantly contributes to a more sustainable manufacturing process. By employing precise material deposition techniques, MJF minimizes waste, making the production process more efficient and environmentally friendly (source). The ability to reuse powder material and the reduction of excess waste align with the growing emphasis on sustainability in veterinary care and manufacturing. This not only reduces production costs but also supports WIMBA’s commitment to environmental responsibility.

Modular Design for Enhanced Adaptability

One of the features of WIMBA orthotics is their modular design. Some components, such as the tokens and hinge caps, are designed to be upgraded or replaced over time. This modularity allows veterinarians to tailor the orthotic’s performance to the pet’s evolving needs, ensuring that the device can adapt as the pet recovers (interchangeable tokens) or if adjustments are needed for improved mobility. This flexibility not only enhances the therapeutic benefits of the orthotic but also extends its usable lifespan, making it a more sustainable and cost-effective solution for pet owners.

Final Thoughts

The integration of HP Multi Jet Fusion technology in the production of WIMBA orthotics marks a significant leap forward in veterinary care. This innovative approach ensures that our orthotics are not only of the highest quality but also customizable, sustainable, and efficient to produce.

The combination of advanced materials and precise printing allows for reduced pressure points and enhanced breathability, addressing issues such as excessive sweating and skin irritation. Pets using WIMBA orthotics experience increased comfort and effective support, which translates into faster and more comfortable recoveries.
