What kind of dust and moisture protection will the builds have?

We use several types of materials for printing.

The properties of HP PA 12 polyamide make it possible to create device cases and parts with an IP67 rating for dust and water protection. Finished products are not harmed by contact with fine dust. Physical properties are preserved when in contact with rain, running water, or sea waves. Products made of this material withstand a 30-minute immersion in water to a depth of 1 meter. Due to the high density of the polymer, such products do not absorb water and retain their dimensions in a humid environment.

Because of its non-porous structure, polypropylene (PP) is resistant to water, so products made from this material do not require additional treatment with epoxy resins. The water absorption of polypropylene is very low; kept at room temperature for over 6 months, the material absorbs liquids of less than 0.5% of its own weight, and at 60°C, it absorbs less than 2% thereof.

Thermoplastic polyurethane (TPU) also has high water-repellent properties: per 24 hours at 23ºC, the water absorption of the material is 0.6%, the protection level is IP67.
