Prusament PETG Jet Black 1kg (NFC)

Prusament PETG Jet Black 1kg (NFC)

Prusament PETG Jet Black is a high-quality black PETG filament manufactured in-house by Prusa Research / Prusa Polymers a.s. with an emphasis on high precision, color consistency, and perfectly wound spools. The with NFC variant allows for storing and reading information about the specific spool.

Main advantages and use

• Universal technical material – suitable for functional prototypes, workshop parts, covers, brackets, fixtures, and aesthetic models
• High dimensional accuracy (typically ±0.02 mm) ensures reliable printing even on long jobs
• Good thermal resistance (around 68 °C) – suitable for parts that may warm up slightly (electronics, car interior, etc.)
• Excellent adhesion between layers – strong functional prints with less risk of cracking
• Low shrinkage and warping – easy printing even for larger objects
• Deep Jet Black color – more matte, technical look without unwanted gray shades
• NFC chip on the spool – quick loading of filament parameters and inventory management with compatible solutions

Recommended print settings

Specific values may vary slightly depending on the printer and conditions; the ones listed below serve as a proven foundation.

• Nozzle temperature: approx. 240–260 °C (typically ~250 °C)
• Bed temperature: approx. 70–90 °C (typically ~80 °C)
• Print speed: up to around 200 mm/s depending on printer capabilities
• Cooling: roughly 30–60% (often around 50%), depending on the model shape
• Print bed: smooth, satin, or lightly textured PEI; always well-degreased (IPA)

Printing tips

• For the first layer, choose a slightly higher bed temperature and lower speed to ensure the print adheres well.
• PETG tends to string more – correctly set retraction, a slightly lower nozzle temperature, and a clean nozzle will help.
• When printing on a smooth PEI sheet, avoid too much pressure on the first layer to prevent surface damage.
• Store the filament in a dry place, ideally in a closed box or with a moisture absorber.

Typical use

• Brackets, clamps, and mounting elements
• Electronics covers, junction boxes, cable organizers
• Functional prototypes of mechanical parts
• Household and workshop parts (hooks, storage systems, fixtures)
• Design and decorative items in elegant black color
