Cobalt Blue PLA is a bold, saturated blue PLA filament. Use it for logos and signs, team colors, toys and color-coded parts. Want a darker blue? See Navy Blue. Need cobalt blue in a tougher material that handles more heat? See Cobalt Blue PETG.
Like all Coex Standard PLA, it's made in our Green Bay, Wisconsin facility from virgin NatureWorks Ingeo 4043D resin — colorant only, no fillers — and held to ±0.03mm diameter on every spool. Our Standard PLA holds its own against most brands' PLA+.
Need stronger parts? Cobalt Blue also comes in 1.75mm PLA Prime, which prints much like Standard PLA but is significantly stronger once annealed (heat-treated after printing).
Slicer profile: the COEX PLA profile for 1.75mm filament is built into OrcaSlicer 2.3.2 and later. In Filament Selection, choose vendor COEX 3D, then COEX PLA.
