Contents: 10 x 800 cm³ = 8000 cm³ (€0.30* / 1 cm³) Onyx is an engineering thermoplastic and produces mechanically and thermally resilient components. On its own, the material is twice as stiff as ABS and can be reinforced with any Markforged continuous fiber. Onyx sets the bar very high in terms of surface quality, chemical resistance, and heat resistance.
