Medical / Antibacterial

The medical filament category includes materials with a specific standard linked to the world of health or medicine.

These filaments with different properties will be classified according to the standards in force for more or less prolonged contact with the skin or mucous membranes, for example. There are also filaments with antibacterial properties, capable of limiting or eliminating the spread of viruses.

These so-called medical filaments generally meet class I requirements (off-measure and sterile), so these 3d filaments are suitable for non-invasive, non-intrusive medical device (MD) applications and are more geared towards therapeutic, accessory or educational applications.

As with filaments suitable for food contact, it is your responsibility to ensure continuity of certification via your transformation process (in this case 3d printing). In the case of the manufacture of class I devices or accessories, a simple declaration may suffice.

For all other class Ia(s) / Ia(m), II and III applications, a dossier must be submitted before any marketing or certification. As a reminder, PEEK filaments are not compatible with desktop 3D printers. This inert plastic material used in implantology is out of category. The important thing to bear in mind is therefore to assess the feasibility of your project for therapeutic or medical purposes.

Filaments with antibacterial or virucidal properties have a real active effect, and incorporating active particles into your PLA or Flexible filament will effectively destroy viruses. The manufacturer Nanovia even attests to 99.9% destruction of viruses within 4 hours. These filaments were of course developed following the COVID19 crisis, and are ISO 21702 certified, so they now meet health and safety requirements.

Why choose a medical filament?

The medical world is regulated and all applications linked to this universe include stricter standards than other work environments. Even the smallest element considered as a medical device must meet various requirements. The choice of your 3d printing filament must therefore be made with care and pragmatism. Choosing a filament with favourable or certified characteristics is essential. Available in 1.75mm and 2.85mm, more or less technical, our selection of medically oriented reels must be accompanied by particular vigilance when it comes to the condition of your equipment. Clean your extrusion system carefully and thoroughly and don't contaminate your material during processing. Don't forget the steel nozzle!
