ELEGOO PC Filament 1.75mm Black 1KG - Tough, Heat Resistant PC

In this review of ELEGOO PC Filament 1.75mm Black 1KG the bottom line is simple: this filament is aimed at makers and engineers who need tough, heat resistant parts rather than decorative prints. The reviewer found it most valuable for functional prototypes and small production runs because of its outstanding mechanical properties and thermal stability. It prints cleanly when the filament has been dried and the printer is enclosed, delivering parts that resist impact and maintain dimensional accuracy over time.

Key Features

• High impact resistance: The material stands up to stretching and compression, making it suitable for functional parts and prototypes that need strength.
• Excellent heat resistance: Thermal stability makes this filament a good choice for components exposed to higher temperatures, such as basic automotive or electrical parts.
• Dimensional stability: Low creep and reduced warping help large models and high-precision parts keep their intended dimensions.
• Consistent diameter: The 1.75 mm tolerance aids steady extrusion and predictable flow for repeatable prints.
• Dry-storage packaging: The spool arrives vacuum-sealed in aluminum foil to limit moisture pickup and reduce bubbling or clogging when printed after proper drying.

Who It's For

This filament is best for hobbyists with experience tuning print settings, product designers making durable prototypes, and small shops that need heat resistant, dimensionally stable parts. Users printing functional components for housings, brackets, or simple mechanical assemblies will benefit most from the material's toughness and thermal resistance.

It is not the right choice for casual PLA users seeking easy, low-temperature ornamental prints or for open-frame printers; the formulation requires an enclosed printer and a proper dry-out procedure for reliable results, so beginners or those without a heated enclosure should consider alternatives.

Pros & Cons

Pros

• Strong, impact-resistant prints that perform well under mechanical stress.
• Good thermal stability for parts exposed to higher temperatures.
• Low warping and dimensional stability help with large or precision prints.
• Arrives vacuum-sealed to limit moisture and print issues when dried properly.

Cons

• Requires an enclosed printer and recommended drying (80 +/-5 C for 8 hours), which may be inconvenient for some users.
• Some users report mixed experiences with stringing and adhesion depending on printer setup and tuning.

Frequently Asked Questions

Do I need to dry the filament before printing?
Yes. Drying at about 80 +/-5 C for 8 hours is recommended to avoid moisture-related printing problems.

Can I use this filament on any 3D printer?
It is compatible with most enclosed 3D printers; open-frame printers are not recommended due to the high temperature and enclosure needs.

Is this filament good for large prints?
Yes. Low warping and dimensional stability make it suitable for larger models and high-precision parts when settings are tuned correctly.
