The Risks
As industries increasingly prioritise safety, sustainability, and environmental responsibility, the shift towards TPO-free resins is also gaining momentum. The photoinitiator TPO (Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide) has been widely used in the curing processes in multiple industries due to its effective curing properties under UV light.
In recent years, increased environmental and health worries have resulted in more stringent regulations. A study conducted in Germany in 2020 discovered that TPO caused significant histological changes in the testicles of male rats, ultimately leading to infertility. Additionally, a separate study in France confirmed that consistent reproductive toxicity was observed in male rats, which also led to infertility. These findings, along with the growing regulatory scrutiny, have led the European Union to enforce a ban on products containing TPO starting in the year 2025.
This ban has accelerated the search for safer alternatives.
Our Approach
At Resine-3D, we are committed to keeping our clients safe by offering TPO-free resins. We have been proactive in eliminating TPO from most of our resins to ensure that our resins not only meet but also exceed the upcoming EU regulations. For the few remaining resins we have that still contain TPO, we are working extremely hard to remove this substance before the EU deadline. This approach reflects our commitment to the health and well-being of our clients.
Our dedication to innovation, safety, and quality resins drives us to continuously improve our formulations, to guarantee that every resin we offer is as safe as possible.
Conclusion
The shift towards TPO-free resins and products is not only a regulatory need but also a crucial step towards ensuring the safety and sustainability of the 3D printing industry.
At Resine-3D, we pride ourselves on leading the way by offering innovative, high-quality, and high-performance solutions that prioritize the health and well-being of our clients.
