## Summary description

ROSA3D PCTG 1.75 mm filament, 1 kg refill pack in gray. Thermoplastic PCTG offers enhanced toughness and chemical resistance compared with PLA, suitable for functional parts, prototypes and mechanical components. Compatible with standard 1.75 mm FDM/FFF 3D printers; recommended print settings depend on printer and part geometry.

## Long description

ROSA3D PCTG 1.75 mm filament in a 1 kg refill pack (gray) is a thermoplastic designed for FDM/FFF 3D printing. PCTG combines good toughness and chemical resistance with ease of printing on standard 1.75 mm extruders. This gray refill is aimed at users who need functional parts, prototypes or mechanical components where increased durability and post-processing flexibility are required.
Advantages
PCTG offers higher impact resistance and improved chemical resistance compared with PLA while remaining compatible with most desktop 1.75 mm FDM/FFF printers. The material prints smoothly and is suitable for parts that require moderate mechanical strength, transparency reduction in gray tones and reliable layer adhesion. The refill pack format provides material for extended print runs and reduces packaging waste for frequent users.
Suitable for
 Functional prototypes and concept models
 Mechanical parts and housings requiring toughness
 Parts exposed to mild chemicals, moisture or moderate wear
 General-purpose prints where improved durability is needed over PLA
Key specifications
 Material: PCTG thermoplastic
 Diameter: 1.75 mm nominal
 Net filament weight: 1 kg (refill pack)
 Colour: gray
 Compatibility: standard FDM/FFF 3D printers using 1.75 mm filament
How to use
Load the filament spool onto the printer or feed the refill following your printer manufacturer's guidance for 1.75 mm filament. Typical extrusion temperatures for PCTG are higher than PLA; start with a moderate temperature range recommended for PCTG by your printer or filament guidelines and adjust based on layer adhesion and surface finish. Use a heated bed to reduce warping and set appropriate bed temperature. Calibrate retraction and print speed to minimise stringing and ensure dimensional accuracy. Allow printed parts to cool gradually for best mechanical properties.
Usage recommendations
For consistent results, print with a heated bed and use moderate print speeds. Adjust extrusion temperature and retraction settings according to part geometry and printer configuration. Store the filament in a dry environment or sealed container with desiccant to maintain print quality over time.
