Fast Production and Clean Working Environment for Insole Manufacturers

May 31, 2024

LutraCAD B.V. is based in Heeswijk-Dinther in the Netherlands, and provides specialized software solutions for orthopaedics and podiatrists in over 104 countries. By merging advanced technology with healthcare needs, LutraCAD aims to help practitioners simplify and automate the production of custom insoles, shoe lasts, midsoles, test shoes, and braces.

Their co-founder and CEO, Niels den Otter, explains that LutraCAD primarily uses the Raise3D E2 printer, specifically chosen for how efficiently it can produce insoles. Additionally, their own customers in the healthcare sector, also prefer Raise3D as a solution, employing Raise3D printers for various printing needs.

The Challenges of Traditional Production

Traditionally, podiatrists crafted insoles either manually or with milling machines, typically utilizing blocks of EVA or Polypropylene. However, this process generates substantial dust, noise, and requires significant time and investment. Moreover, it has a significant environmental impact.

Additionally, using traditional raw material means having a large quantity of it in stock. Conversely, the filament needed for 3D printing requires much less storage space, meaning less stock, so the value of the material you have to keep in stock is also lower. And that can be reinvested in the company.

Why Go for A Modern Production Technology?

3D printing offers a more efficient, cost-effective, and environmentally friendly alternative. By adopting the Raise3D E2 printer, LutraCAD was able to streamline the production process, reduce waste, and create a cleaner working environment. The insoles can be produced in a matter of hours, with time savings of around 50%.

In addition to its affordability and user-friendly features, the printer boasts a closed-box design with a HEPA filter, ensuring the safety of those who use it.

Transitioning to 3D printing eliminates the need for extensive post-processing, significantly reducing labour time and costs. Moreover, it minimizes the dependency on specialized knowledge for sanding and shaping insoles, making it accessible to a broader range of practitioners.

Looking ahead, LutraCAD aims to continue enhancing efficiency and precision in practitioners’ work.

Finding the Right Partner

“We were investigating the best solution to print TPU,” Niels says. “All the reviews on the internet led us to Raise3D as the best TPU printer available on the market.” TPU is a common choice of printing material, as is Polypropylene (PP), and in the case of insoles, their properties are much appreciated.

“TPU for insoles because this is flexible and soft,” Niels affirms. “Polypropylene because people need to be able to stand on a print of just about 3 mm thick and should not break. It is wear-resistant, and the layer adhesion is great.”

He goes on to describe the fruitful relationship between LutraCAD and Raise3D. “After our research, it must have been a coincidence, Raise3D reached out to us to form a partnership. Now it has been 3 years since our first contact.”
