Prusament PETG 1.75mm 1kg Ultramarine Blue Transparent

Guaranteed Color Consistency

Every Prusament color is formulated and locked to a documented spectroscopic recipe. We test every batch against the standard before it ships. If you run out mid-project, the next spool will match perfectly.

±0.02 mm Precision

We measure and record diameter and ovality continuously across the full length of every single spool, and we openly publish the actual data for tracking accuracy.

High Quality Verification

Every spool comes with a barcode to check its exact metrics online: diameter readings along the entire length, precise weight, and ovality parameters.

Perfect Winding Control

Wound under perfectly balanced tension on precision automation machinery. Avoids overlaps or knots, guaranteeing an even feed from start to finish.

Pros

• Easy to print, suitable for beginners and professionals alike
• High strength and durability
• Good high-temperature resistance
• Low shrinking and warping
• Easier to sand than PLA (softer, less melting)

Cons

• Glossy surface (highlights imperfections)
• Less resistant than PC Blend and other advanced materials
• Possibility of stringing (may require occasional drying)
• Poor bridging characteristics

PETG is the best technical material to start with

PETG is almost as easy-to-print as PLA. It doesn't require extra surface preparations, storing in the drybox, or using special sheet and nozzle. The overall easy printability makes it suitable for beginners and advanced users alike.

Before printing, make sure the print sheet is clean.

To achieve the best adhesion, it is important to keep the surface clean. The best option is Isopropyl alcohol available in drugstores, which works the best for PETG and other materials as well. Pour a little amount on an unscented paper towel and wipe the print surface. The print sheet should be cleaned while cold for the best results.

Use a glue stick when printing on smooth PEI sheet

PETG has strong adhesion to the smooth PEI surface. Printing directly on it may damage the sheet.

Drying may improve the print quality, especially when stored in wet conditions.

PETG is less hygroscopic than most materials, so drying is not usually necessary. However, if you notice stringing, bubbling, or surface roughness, drying at 55 °C for 6 hours will usually resolve it.

Use superglue for gluing large models

PETG can be glued with many types of glue. We recommend using superglue for most of the parts. Chemical bonding is usually difficult, as PETG is soluble in dangerous chemicals only.
