Product description

Prusament PVB Dark Blue Transparent 500g (NFC) is a top-of-the-line PVB filament developed and manufactured by Prusa Research in the Czech Republic. The PVB (polyvinyl butyral) material is designed primarily for visually attractive models, where you will appreciate its translucency and the possibility of chemical smoothing in isopropyl alcohol (IPA).

The dark blue transparent variant is ideal for printing decorative items, designer vases, lampshades, jewelry, cosplay and movie props, where the combination of deep blue color and translucent effect after smoothing stands out.

Prusament production takes place in-house with an emphasis on diameter precision of ±0.03 mm, consistent color, and rigorous quality control of every spool.

Key features

• PVB material (polyvinyl butyral) – design filament for visual parts
• Dark Blue Transparent color – ideal for translucent and backlit models
• IPA chemical smoothing capability – glass-like, smooth surface without visible layers
• Printing settings similar to PLA – easy printability even for beginners
• Mechanical properties similar to PETG / CPE – good toughness while maintaining easy printing
• Low warping – suitable even for larger models
• Excellent bed adhesion – reliable first layer
• Hygroscopic filament – the material absorbs moisture, recommended to store in dry conditions
• Made in CZ, precision ±0.03 mm – stable diameter and reliable material flow
• NFC spool (OpenPrintTag) – contains stored information about the material, easy identification by compatible devices and applications

Recommended use

Ideal projects:

• Vases and decorative containers – look like glass after IPA smoothing
• Lamps and lampshades – filament translucency creates an effective play of light and shadows
• Jewelry and fashion accessories – small, detailed parts with an attractive gloss
• Design and exhibition models – prototypes, props, cosplay parts
• Translucent covers and elements – where it is desirable to see contours or light through the part

The material is suitable for beginners and advanced users who want to push the aesthetics of their prints to a "glass" level.

Printing recommendations

Basic settings

• Filament diameter: 1.75 mm
• Nozzle temperature: approx. 215 °C ± 10 °C
• Bed temperature: approx. 75 °C (generally 65–85 °C depending on bed and printer)
• Recommended bed surface: smooth or satin PEI sheet
• Cooling: active, fan 100 %
• Enclosure: not necessary, PVB has low warping

Tips for best results

• To fully utilize translucency, use a larger nozzle (e.g., 0.6–0.8 mm) and
  • print in Spiral/Vase Mode for single-walled vases and shades
• After printing, the model can be smoothed using IPA (isopropyl alcohol):
  • short exposure to vapors or controlled immersion creates a glass-like, smooth surface
  • after smoothing, let the model dry and air out thoroughly
• PVB is hygroscopic – for best results:
  • store the spool in a closed bag/box with silica gel
  • at signs of "popping" from the nozzle, dry the filament as recommended by the manufacturer

Material limitations

• Lower heat resistance – similar to PLA, typically up to approx. 60 °C
  • not recommended for parts exposed to long-term sun (e.g., interior of a parked car)
• Worse interlayer adhesion than PLA – lower bond strength must be expected for highly stressed and thin parts
• Not suitable for functional mechanical parts, parts in heat, or technical applications where high temperature and mechanical resistance is needed

NFC Spool and OpenPrintTag

This Prusament PVB is wound on a new generation of spools with an NFC chip using the open OpenPrintTag standard:

• NFC tag on the spool stores key information about the material (type, color, production batch, etc.)
• Offline operation – all important data is directly on the tag, not dependent on the cloud
• Easy integration – compatible devices or applications can automatically recognize the spool and simplify print settings
• The spool is designed for easy disassembly and reuse (refill concept)

Technical parameters

Who is the filament suitable for

• Users who want attractive, "glass" models without visible layers
• Owners of Original Prusa and other FDM/FFF printers with 1.75 mm filament diameter
• Beginners transitioning from PLA to design material
• Advanced creators, designers, cosplay and prop makers looking for a highly aesthetic filament

Thanks to the combination of easy printing, IPA smoothing, and translucency, Prusament PVB Dark Blue Transparent 500g (NFC) is an excellent choice for everyone who wants to push the appearance of their prints to a professional level.
