Polymaker PETG 1.75mm 1KG Filament - Black, High-Flow Impact-Resistant for Fast, Durable Prints

Polymaker PETG 1.75mm (1KG) in Black is a high-flow, impact-resistant 3D printing filament engineered for fast, stable printing with strong layer adhesion and minimal warping.

Polymaker's PETG blends printability and durability in a general-purpose filament suited for prototyping, functional parts and large prints. Its formulation focuses on consistent melt flow for high-speed extrusion, improved interlayer bonding for toughness, and reduced stringing to keep post-processing to a minimum. This black 1.75mm spool holds 1 kilogram of filament—compatible with most hobbyist and prosumer FDM/FFF printers that accept 1.75mm feed stock.

How does this filament help when printing at higher speeds?

Polymaker PETG is tuned for excellent melt flow, which supports elevated printing speeds while maintaining steady extrusion. That means fewer under-extrusion artifacts and more reliable surface finish even when pushing print time down.

• Optimized viscosity for smooth flow at speeds up to 500 mm/s.
• Reduced extrusion stalls and more consistent layer laydown.
• Maintains dimensional fidelity at faster travel and print rates.

Will parts be strong and resistant to everyday stress?

Yes — this PETG formulation emphasizes a balance of tensile strength and toughness, producing parts that resist impacts and mechanical wear better than many standard PLA options. Strong interlayer bonding also improves the overall structural integrity of printed components.

• Good tensile strength for functional prototypes and fixtures.
• Durable toughness for snap-fit parts and utility objects.
• Consistent layer adhesion reduces weak planes.

How does it perform with common printing issues like warping and stringing?

Polymaker PETG is formulated to limit warping and shrinkage so prints keep their intended dimensions across different geometries. It also reduces oozing and stringing compared with many generic PETG blends, so models need less cleanup.

• Low-warp formulation for flatter first layers and large surfaces.
• Reduced stringing when using appropriate retraction and temperature settings.
• Stable printing across moderate ambient temperature variations.

What printer settings and preparation give the best results?

Start with manufacturer-recommended nozzle and bed temperatures for PETG, then tune flow and retraction for your specific machine. Proper bed adhesion and minimal drafts will improve first-layer success and long prints.

• Typical nozzle temperature: 230–250°C depending on printer and part.
• Bed temperature: 70–80°C and use a suitable adhesion surface (PEI, glue stick, or blue tape).
• Moderate retraction and slower travel when bridging reduce strings and blobs.

Who is this for? Polymaker PETG 1.75mm (1KG) in Black suits makers, engineers and educators who need reliable, tougher-than-PLA prints at faster throughput. It's ideal for functional prototypes, jigs, enclosures and any application where improved impact resistance, consistent layer bonding and reduced post-processing save time. If you run a prosumer or desktop FDM printer and demand consistent feed, clean surfaces and fewer failed prints in black, this spool is designed to be a dependable, everyday workhorse.
