Kexcelled THE K6™ PLA FR 1.75mm 1kg

Kexcelled THE K6™ PLA FR is a flame-retardant PLA filament designed for 3D printing applications requiring safety, dimensional stability, and good mechanical strength.
Thanks to its formulation, it offers excellent inter-layer adhesion, minimal printing deformation, and reliable performance even when creating functional and technical components.

With a tensile elastic modulus of 4100–4600 MPa and a tensile strength of 35–40 MPa, this material is ideal for parts that need to maintain shape, precision, and solidity over time.
The density, ranging from 1.28 to 1.30 g/cm3, contributes to dense, uniform prints with a clean surface finish suitable for professional products and technical components.

K6™ PLA FR is particularly suitable for enclosures, protective covers, electrical components, jigs, fixtures, and industrial parts exposed to mechanical stress, where fire resistance is an added value.
It is a valid choice for those seeking a PLA that is easy to print but more geared towards industrial applications than standard PLA.
