For 3D-printing lots of different types of filaments can be used, so picking the right filament for your application can be a tough job. That is where case studies could help you in the right direction, and that's why we are sharing this with you!

Sanitronics featuring our EPR InnoPET filament

This case study is about the successful use of EPR InnoPET filament in the development and manifacture of customized drain pipes.

About Sanitronics

Sanitronics is an innovative company with over 20 years of manufacturing experience in public toilets. Sanitronics was nominated for the most innovative SME company of 2018.

The company produces custom-made, self-cleaning public toilet systems. One of these patented designs is “The Revolving Toilet”, which consists of two toilets that rotate and switch after each use. One toilet is being cleaned thoroughly inside and out in the technical room, while the clean one is rotated to the toilet area. This way, every visitor can experience a fully clean and dry toilet. The system has been designed to account for issues such as vandalism, sustainability, comfort and hygiene.

The Requirements

This Revolving Toilet requires custom drain pipes that use complicated designs and have tight tolerances. These drain pipes must be watertight and long lasting. For the revolving toilet, Sanitronics needs to be able to produce these components in house, for small product series.

The Solution

3D printing is the perfect solution for this application. Sanitronics uses a Raise3D printer in combination with BASF Innofil3D filament EPR InnoPET. This material was chosen because of its excellent layer adhesion, which allows Sanitronics to print watertight parts. By using 3D-printed drain pipes, the parts can be constantly developed further and replaced by improved versions. The consistent quality of the filament allows the company to have a reliable in-house production.

Advantages for Sanitronics

  • Ability to print watertight parts
  • Design freedom: perfect for in-house manufacture of small product series
  • Continuous development and immediate use of improved parts
  • Great printability
  • Consistently high print quality

Thanks to the close collaboration between the customer and BASF Innofil3D and the reseller of Sanitronics, SEEDA 3D
Printing Solutions, great applications can be realized. BASF Innofil3D provides support to tailor the print experience and
the application.
