PVB filament is ideal for projects seeking a glass-like finish. To achieve optimal results, it is essential to follow a series of best practices for printing and post-processing that fully leverage its properties. Here are the best tips for successful 3D printing with PVB.

Recommended settings for PVB printing

The extruder temperature should be maintained between 215 ±10°C, while the heated bed should be set between 65 and 85°C. It is recommended to use a satin print sheet or smooth PEI to improve adhesion. Furthermore, it is essential to use the layer fan at 100% to ensure efficient cooling during printing.

Print surface maintenance

A clean surface is key for perfect adhesion. It is recommended to clean the bed with isopropyl alcohol (IPA) on an unscented paper towel, preferably when cold. Alternatively, warm water with neutral soap or denatured alcohol can be used.

Chemical smoothing with isopropyl alcohol

One of the advantages of PVB is its capability for chemical smoothing with IPA. This process allows for a glossy and smooth surface, similar to glass. However, it can also lose fine details and round sharp edges. It is recommended to perform smoothing carefully, especially on parts with delicate details.

Tips for improving transparency

To leverage the translucency of PVB, it is suggested to use the spiral vase mode and then apply IPA smoothing. A lower number of perimeters improves light transmission. The more perimeters added, the less light will pass through the model.

Importance of keeping the filament dry

PVB is a hygroscopic material, so it is crucial to store it in its original bag with silica gel. If moisture absorption is suspected, it is recommended to dry the filament for 4 hours at 60°C before printing. This will prevent defects such as bubbles or irregularities in the layers.

General recommendations

Thanks to its PLA-like ease of printing, PVB is suitable for beginners looking for a premium finish. It is recommended to use a nozzle with a large diameter and activate the spiral vase mode to optimize aesthetics. However, it should be noted that its heat resistance is limited (up to 60°C), so it is not recommended to expose parts to high temperatures such as those inside a car in the sun.

PVB is ideal for vases, lampshades, jewelry, design pieces, and decorative models. By applying these tips, it is possible to obtain clean, strong, and visually stunning prints.
