In the context of the ORPLAST 2 plastics recycling project, we are today announcing the launch of our new recycled material, the 3D filament named Kimya PETG-R. It therefore supplements our existing range of recycled filaments and is the fruit of the ADEME project that began in March 2018. Our new thermoplastic is sourced from the industrial waste of a French manufacturer of medical, pharmaceuticals and luxury goods packaging, which has established its own operation to shred the waste. The Kimya PETG-R is 100% recycled in its natural translucent version and 97% recycled in its white and black versions. In terms of properties, it is similar to our standard PETG (PETG-S), which is ideal for a wide range of applications.
It is several years now since KIMYA launched its range of recycled materials, convinced that it can have a real impact on the environment and the way we manufacture in the industry of the future. Four years ago, the additive manufacturing division of the ARMOR group set itself the long-term objective of recycled plastics constituting between 40% and 100% of its filament range for FDM/FFF 3D printing. The Kimya PETG-R is the fourth and latest product being added to the range.
The manufacturing process of the Kimya PETG-R
It is produced from post-industrial waste sourced from a French company specializing in packaging. The waste is sorted and then shredded: KIMYA collects the pre-shredded raw material in line with its production requirements and converts it into filaments compatible with FDM/FFF 3D printers. Our Kimya PETG-R is currently available in three colors: white, black and translucent in its “natural” version. In practice, our personnel incorporate additives to obtain the pigmentation, resulting in a 97%-recycled material. The translucent version, however, is produced from 100%-recycled material.
Misha Nesaratnam, Product Manager at KIMYA, explains:
“The problem when you are seeking to produce a filament from recycled raw materials is obtaining a stable, regular and single source of supply in order to guarantee consistency and the best possible quality.”
Regarding the Kimya PETG-R, all the shredded raw material is obtained from the same French company. Which processes its own industrial waste. We therefore receive stable quality over the long term.
Properties of the Kimya PETG-R
After performing a range of technical tests on the Kimya PETG-R, we have been able to confirm that it presents mechanical properties very close to the Kimya PETG-S. It is therefore an ideal alternative for anyone seeking a more eco-friendly material. While offering a good balance between flexibility and mechanical properties, and which is benign. As far as applications are concerned, it is especially suitable for manufacturing translucent containers, packaging and parts.Lastly, we recommend a printing speed of between 30mm and 70mm per second. Nozzle temperature of between 230°C and 270°C and a plate heated to between 70°C and 90°C. We suggest you test different print settings depending on the machine you are using.
A comprehensive range of recycled materials
In just 4 years, KIMYA has developed a comprehensive range of 3D printing materials. All sourced from recycled raw materials. This Kimya PETG-R supplements the following filaments:
- The Kimya PLA-R, a 100%-recycled material in its natural version and at least 97% in other colors (Kimya PLA-R White, Gray, Black, Red and Blue).
- The Kimya TPU-R, a 100%-recycled material. It is prized for its great flexibility and elasticity and its resistance to wear and impact.
- The Kimya HIPS-R, a 100%-recycled material. It is a support filament offering excellent surface quality and high impact resistance.
The launch of the Kimya PETG-R concludes the ORPLAST 2 Project but KIMYA’s ambitions do not stop here. In the long term, the objective is for only recycled raw materials to be used. For example, in the production of certain filaments such as the PLA or TPU. So why not deploy this strategy for producing our high-performance materials?
