Spool of c-tech Filament PETG 1.75 mm 1 kg — blue refill

Spool of c-tech Filament PETG 1.75 mm 1 kg — blue refill: a blue PETG filament supplied on a refill spool with 1.75 mm diameter and 1 kg net weight, designed for use in FDM/FFF 3D printers. The c-tech PETG filament provides a balance of tensile strength and moderate flexibility, good layer adhesion and increased chemical resistance compared with standard PLA, making it suitable for functional parts, prototypes and everyday household items. The refill spool format is intended for continued printing with compatible filament holders and spools.

Advantages

c-tech PETG filament combines durability and workability: it offers improved impact resistance and chemical resistance while maintaining reliable layer bonding and dimensional stability for typical FDM/FFF printing workflows. The 1.75 mm diameter ensures compatibility with a wide range of consumer and prosumer extruders. Supplied as a 1 kg refill spool, this product reduces downtime for longer print runs and integrates with systems that accept refill spools.

Suitable for

• Functional mechanical parts and housings
• Prototypes and concept models requiring strength and some flexibility
• Household items and fixtures exposed to moisture or mild chemicals
• Continued printing workflows using compatible refill spool holders

How to use

Load the 1.75 mm PETG filament onto a compatible spool holder or refill system and thread the filament into the printer’s extruder according to the printer manufacturer’s instructions. Typical printing temperatures for PETG are higher than PLA; follow your printer and filament supplier guidance for nozzle and bed temperatures, retraction settings, and print speed to achieve consistent extrusion and layer adhesion. Ensure the filament is dry before printing; if necessary, dry according to recommended temperature and time for PETG. Monitor first-layer adhesion and adjust bed leveling and nozzle distance as needed.

Usage recommendations

Use a heated bed and appropriate adhesion method (e.g., PEI sheet, glue stick or blue tape) for reliable first-layer adhesion. Store the refill spool in a dry environment or sealed bag with desiccant to preserve print quality. When switching from other materials, purge the hotend to avoid contamination. Consult your printer’s guidelines and perform small test prints to fine-tune settings for optimal results.
