Focus on materials: the Kimya PA6-CO filament

KIMYA continues to innovate and expand its range of materials with this new nylon co-polymer filament based on polyamide 6. While nylon is the most widely used material in additive manufacturing (SLS and FDM), Kimya PA6-CO filament stands out for its ease of printing with the FDM technique, which is known to be difficult to print with polyamide materials. The power of this new material lies precisely in its ease of use, especially on open chamber printers!

The properties of PA6-CO

Polyamides are the largest group of engineering thermoplastics. They are mainly used for technical applications thanks to their good mechanical properties (traction, fatigue, low friction) and their resistance to the action of numerous chemical products (oils, greases, hydrocarbons, fuels, aldehydes, ketones, esters, etc.).

Polyamides are polymers composed of carbon, oxygen and nitrogen (amide functions) that come in several grades depending on the number of carbon atoms that make up their monomer. Kimya PA6-CO is a co-polymer, i.e., it is composed of at least two types of polyamides. Kimya has combined the properties of PA6, universally recognized for its robustness, with other polyamides to improve its compatibility with the FDM additive manufacturing process: reducing warping, limiting moisture absorption, etc. The Kimya PA6-CO filament is the ideal alternative if you wish to print parts with good mechanical characteristics, thermal stability, and chemical inertia without the need to use a heated printer.

Using Kimya PA6-CO filament, manufacturers can now take advantage of the FDM technique to produce 3D polyamide parts such as air supply systems, filtration systems and automotive cooling systems.

KIMYA is keen to respond to market demands and aims to expand its polyamide range in the coming months.

Which print settings to choose?

We have carried out multiple printing tests using the Kimya PA6-CO and our recommendations are as follows:

  • Extrusion temperature: 260°C – 290°C
  • Plate temperature: 75°C – 100°C
  • Print speed: 40 – 70 mm/s

Please note: Polyamide filaments are sensitive to moisture, so they should be kept in a dry place and allowed to dry before printing.

The print settings are specific to each 3D printer. We recommend that you conduct several tests before establishing your preferred settings. Please don’t hesitate to contact our sales team if you need any help in making the right choice!
