3D printing material Renkforce RF-4738594

Renkforce RF-4738594 is a white PETG 3D printing filament supplied on a 1 kg spool with a 1.75 mm diameter. Designed for general-purpose and functional prints, this Polyethylene Terephthalate Glycol material combines toughness and flexibility while providing good layer adhesion and dimensional stability. The filament is intended for use with desktop FDM/FFF printers and supports a maximum extruder tip temperature of 240 °C, making it compatible with many common hotend setups.

Advantages

The PETG composition offers a balance of strength and ductility, producing parts that resist impact better than many rigid materials while remaining less brittle than standard PLA. Good interlayer bonding reduces delamination risk and simplifies post-processing such as sanding or drilling. The filament's white color provides a neutral base for painting or dyeing and improves visibility of fine details during printing. Consistent diameter and spool winding contribute to steady extrusion and fewer print failures.

Suitable for

• Functional prototypes and end-use parts that require impact resistance and slight flexibility
• Mechanical components, brackets and enclosures for indoor use
• Decorative items, models and educational prints that benefit from a white surface
• Parts that will be sanded, glued or painted after printing

Key specifications

• Material: Polyethylene Terephthalate Glycol (PETG)
• Colour: White
• Filament diameter: 1.75 mm
• Spool weight: 1 kg
• Maximum recommended extruder tip temperature: 240 °C

How to use

Load the 1.75 mm PETG filament into a compatible FDM/FFF printer and set the hotend temperature up to 240 °C according to your printer and hotend specifications. Use a heated bed and moderate bed temperature to improve adhesion; consult printer-specific guides for optimal bed settings. Print at moderate speeds and enable retraction settings appropriate for PETG to reduce stringing. Allow printed parts to cool gradually to minimise warping and maintain dimensional accuracy.

Usage recommendations

Store the filament in a dry environment or sealed container with desiccant to prevent moisture absorption. For best results, calibrate extrusion multiplier and first-layer height before printing complex parts; consider a brim or raft for improved bed adhesion on larger objects.
