Prusament PVB Bright Green Transparent 500g (NFC)

Product Description

Prusament PVB Bright Green Transparent 500g (NFC) is a high-quality PVB filament manufactured in-house by Prusa Research / Prusa Polymers. It is a polyvinyl butyral (PVB) material designed primarily for design and visual applications, where its translucency and the possibility of chemical smoothing in isopropyl alcohol (IPA) vapors stand out.

Thanks to the transparent deep green color Bright Green, impressive "glass-like" models are created after smoothing, ideal for:

• decorative vases and bowls
• lamps and lampshades (light passage, color effects)
• jewelry, accessories, cosplay, and film props
• various design and presentation prototypes

Prusament PVB prints as easily as PLA, while offering better mechanical properties (on the level of CPE/PETG) and very good adhesion to the bed. Due to low shrinkage, it is also suitable for larger models, where it minimizes deformation and peeling of corners.

Key Features

• PVB Material (polyvinyl butyral) – design, translucent filament for visual applications
• Bright Green Transparent – deep green transparent shade for impressive translucent prints
• Chemical Smoothing with IPA – the surface "melts" in isopropyl alcohol vapors to create a smooth, glossy, almost glass-like finish
• Easy Printing, similar to PLA – no enclosed chamber, special nozzle, or exotic bed preparation required
• Good Mechanical Resistance – properties close to CPE/PETG
• Low Warping and Good Bed Adhesion – reliable printing even for larger objects
• Diameter 1.75 mm with ±0.03 mm precision – top-tier printing stability, lower risk of nozzle clogging
• Spool with NFC chip (OpenPrintTag) – smart spool allowing identification and tracking of material in compatible systems
• Made in EU (Czech Republic) – Prusa's own production line ensures constant quality and color consistency

Recommended Use

This PVB filament is particularly suitable for:

• Decorative models: vases, bowls, statues, logos, trophies
• Lighting: lamps, lampshades, light covers, diffusers
• Jewelry and fashion accessories: rings, pendants, earrings, brooches
• Cosplay and film props: translucent costume parts, effect components
• Design prototypes: transparent covers, product concepts, demonstration models

For functional mechanical parts stressed by heat or impact, it is better to choose other materials (e.g., PETG, CPE, PC, Nylon). PVB is optimized mainly for appearance, translucency, and easy smoothing.

Printing Settings (Manufacturer's Guidelines)

• Nozzle Temperature: approx. 215 °C ± 10 °C
• Bed Temperature: approx. 75 °C
• Recommended Print Sheet: Smooth PEI / Satin PEI
• Print Speed: similar to PLA (approx. 40–60 mm/s, depending on printer and model)

Before printing, it is recommended to:

• thoroughly clean the print bed (IPA, or according to printer manufacturer's recommendations)
• ensure the correct first layer (height, pressure, calibration)

Chemical Smoothing with IPA

One of the main advantages of PVB is its solubility in isopropyl alcohol. This allows for simple chemical smoothing:

1. Print the model with a sufficient number of perimeters and infill according to intended use.
2. Ensure the model is dry (vent any moisture after printing).
3. Expose the model to IPA vapors (in an enclosed chamber, using a smoothing device, or other safe solution).
4. The surface will gradually melt and smooth – layers will optically disappear and the model will gain a glossy, smooth surface and increased translucency.

When working with IPA, always follow safety principles – good ventilation, eye and skin protection, no open flames, etc.

Moisture and Storage

PVB is a hygroscopic material, meaning it easily absorbs moisture from the air. This can lead to:

• bubbling during printing
• degraded surface quality
• reduced strength of the printed part

For best results:

• store the spool in a closed container with desiccant (silica gel bags, etc.)
• if moisture is suspected, dry the filament according to manufacturer recommendations (filament dryer, food dehydrator, etc.)

Technical Specifications

Advantages and Limitations of PVB Material

Advantages:

• very easy printing (similar to PLA)
• attractive translucent appearance, glass effect after smoothing
• excellent adhesion to the bed
• low warping and deformation, suitable for larger models
• good mechanical properties (comparable to CPE/PETG)

Limitations:

• lower temperature resistance – unsuitable for parts exposed to higher temperatures
• hygroscopicity – need for proper storage and potential drying
• worse layer adhesion than PLA – for highly stressed functional parts, consider another material

Who Prusament PVB Bright Green is Suitable For

This filament will be especially appreciated by:

• beginners and advanced users who manage common PLA printing and want to enhance the appearance of their models
• designers, decoration creators, cosplayers, modelers, and hobby users
• owners of FDM/FFF printers with a 1.75 mm nozzle looking for a premium translucent material with top-tier consistency

Due to its ease of printing, yet specific nature of chemical smoothing, it is particularly suitable for "intermediate" level users and above, however, even a motivated beginner can quickly learn to work with it.
