Dynalabs PLA 870 Filament 1.75mm 1kg

Dynalabs PLA 870 Filament 1.75mm — Maximum Heat Resistance in a PLA Filament

The Dynalabs PLA 870 represents the top tier of PLA performance. Built on an advanced high-crystallinity resin, PLA 870 delivers the highest heat resistance achievable in any PLA-based filament — after annealing, parts can withstand temperatures exceeding 140°C, putting it in territory normally reserved for ABS and Nylon. At $16.99 per kilogram, it bridges the gap between easy-to-print PLA and high-performance engineering materials.

Available in 6 professional colors: Black, White, Bordo, Natural, Silver Grey, and Turquoise. The color palette is intentionally focused on neutral and industrial tones that suit functional and professional applications.

PLA 870 vs. PLA 850 vs. Standard PLA

Think of it as a ladder: PLA Basic ($12.99) is the easiest to print but softens at 55°C. PLA 850 ($12.99) offers moderate improvement with annealing up to 120°C. PLA 870 ($16.99) is the premium option, reaching 140°C+ after annealing — making it viable for under-hood automotive parts, electronics enclosures, and kitchen applications where heat exposure is unavoidable.

Key Specifications

Recommended Print Settings

PLA 870 requires slightly more attention than standard PLA. Print at 210–220°C nozzle temperature with a 60–70°C heated bed. A PEI build surface provides the best adhesion. Print slower (40–60mm/s) for the first few layers. For annealing, bake finished parts at 90–110°C for 30–60 minutes. Support the part on a bed of sand or salt to prevent warping during the annealing process.

Pro Tips

Annealing PLA 870 causes predictable shrinkage of approximately 2–5%. Measure your test prints before and after annealing to calculate the exact scaling factor for your specific printer and settings. Once calibrated, you can design parts that achieve precise final dimensions after heat treatment. This makes PLA 870 a viable alternative to injection-molded parts for small production runs.

Best Applications

Automotive interior components, electronics enclosures near heat sources, kitchen utensils, coffee cup holders, lamp housings, industrial jigs exposed to heat, and any application where PLA's typical 55°C softening point is a dealbreaker. PLA 870 lets you keep the easy printability of PLA while solving its biggest weakness.
