Prusament PC Blend 1.75mm 970g Jet Black

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

• High temperature resistance (up to 113°C)
• High impact and wear resistance (very strong and rigid material)
• Good dimensional stability in comparison with other PC filaments
• Prints don't deform under pressure over time
• Good electrical insulating properties
• Styrene-free (non-toxic compared to ABS and ASA)
• Very low moisture absorption (compared to other polycarbonates)

Cons

• Large models tend to warp (printing in enclosure recommended)
• Requires high printing temperatures (not compatible with Original Prusa MINI)
• Produces minor odors during printing

Larger models may require enclosure

You may encounter some issues related to the shrinking (warping) of the material, especially when printing larger models. This effect is much less severe than with other polycarbonates, but even with the heatbed set to 110°C, the prints can shrink and warp, causing them to detach from the print bed. This issue can be eliminated by printing inside an enclosure or by adding a tall skirt around the object.

Occasional drying may be necessary

When compared to other polycarbonates, the Prusament PC Blend absorbs moisture very slowly. However, when stored in a humid area, it may require drying before printing. We recommend drying for 5 hours at 85 °C. Don't forget to read the drying instructions in our dedicated article.

Print extra large parts with PC Blend Carbon Fiber

Extra-large prints (full print volume) may be unprintable with Prusament PC Blend due to high shrinkage. We recommend printing extra-large models with PC Blend Carbon Fiber, which has similar properties but significantly better dimensional stability.
