Description
Product Reviews

Bambu PVA is a water-dissolvable support material. It provides reliable support for complex designs and overhangs, which can be easily dissolved in water after printing. Compatible with various filaments, it simplifies post-processing and reduces the risk of damaging the printed object during support removal.

Bambu PVA possesses the ability to dissolve in water, penetrating deep into the intricacies to provide support where regular supports fall short. With Bambu PVA you can design and print models that were previously impossible.

Water-soluble support material can accommodate zero top interface spacing, guaranteeing a seamless bond with the print surface, resulting in precise and smooth support contact surfaces for your prints.

Printing Tips

Drying conditions: 80℃ for 12 hrs. To achieve optimal printing performance, it is recommended further drying before use and after storage. For more details please refer to: Filament drying instructions on Bambu Lab Wiki.
Please carefully read PVA Printing Guide before starting the printing process.
PVA is suitable for use with AMS and AMS lite in a dry state. If the filament becomes soft or sticky due to moisture, it must be dried again before use to prevent issues such as feeding failure, nozzle clogging, and low print quality.
PVA may darken in color after extended storage or multiple drying cycles, but it won't affect its printing performance or support capabilities.
Recommend to use normal support instead of tree support. Tree support is more likely to collapse during printing.
Use warm water to speed up the dissolving process. But if supporting PLA, the maximum water soaking temperature should not exceed 50℃ to prevent deformation of the main model.
Waiting for complete dissolution is not necessary when soaking and dissolving PVA support. You can manually remove the partially dissolved PVA support to reduce the waiting time.
When dissolving supports in water, some parts of the main model may leak in water. To mitigate this risk, please refer to: Reduce the risk of prints leakage guide on Bambu Lab Wiki.
Depending on the use case, Bambu PVA can also be used solely for printing the support interface to minimize material waste and printing time.
Feel free to reuse your Bambu Reusable Spool. Bambu Lab has designed the entire filament feeding system around a reusable spool design and achieved at least 20% less plastic waste in filament consumption.
