3D printing filament Spectrum TF-24019 PETG 1.75 mm Blue 1 kg

Spectrum TF-24019 PETG 1.75 mm Blue 1 kg is a spool of PETG (Polyethylene Terephthalate Glycol) filament designed for FDM 3D printers. The filament has a nominal diameter of 1.75 mm and comes on a 1 kg spool in a Performance Blue colour. PETG combines good mechanical strength, chemical resistance and reliable layer adhesion, making this filament suitable for printing functional prototypes and durable parts where toughness and ease of printing are required.

Advantages

Spectrum PETG offers a balance of strength and flexibility with improved impact resistance compared with standard PLA. The material exhibits good interlayer bonding and lower warping than many engineering-grade plastics, allowing consistent dimensional results across medium- to large-size prints. Its chemical resistance and relative moisture tolerance make it suitable for parts that may face light exposure to oils, detergents or humid environments. The 1.75 mm diameter is compatible with most consumer and prosumer FDM printers.

Suitable for

• Functional prototypes and jigs
• Mechanical parts and housings
• Tools, clips and brackets requiring impact resistance
• Decorative prints and durable consumer items

Key specifications

• Material: Polyethylene Terephthalate Glycol (PETG)
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg of filament
• Colour: Blue (Performance Blue)
• Suitable printing technology: Fused Deposition Modeling (FDM)

How to use

Load the 1.75 mm filament into a compatible FDM 3D printer following the manufacturer's filament-loading procedure. Recommended print settings typically fall in the range of 230–250 °C nozzle temperature and 60–80 °C heated bed temperature, but actual parameters should be adjusted to your specific printer and part geometry. Ensure the filament is dry before printing; if necessary, dry according to standard PETG drying practices. Use moderate print speeds and adequate cooling for overhangs where required.

Usage recommendations

Store the filament in a dry, cool place and keep it sealed when not in use to minimize moisture uptake. Test a small calibration print to fine-tune temperature and flow settings for optimal surface finish and dimensional accuracy. For strong mechanical parts, increase wall count and infill percentage and consider annealing only if your application and printer workflow support post-processing of PETG.
