- Product Details
- DescriptionBVOH (Butenediol Vinyl Alcohol copolymer) is an advanced water-soluble support material for complex multi-extrusion 3D prints. BVOH adheres to almost all print materials ('build materials') and dissolves in water faster than PVA support materials.Its thermal stability is optimised to eliminate any risk of clogginghot-end due to thermal degradation.
Key features
- Excellent adhesion with almost all printing materials
- Excellent solubility in water
- Resistant to thermal degradation due to optimised material flow properties
- Eco-friendly
- Waste can be disposed of by dissolving it with water in the domestic sewage system
Applications
- Reliable multi-extrusion 3D printing of complex structures requiring water-soluble substrates
- 3D printing of geometries with large overhangs or complex hollow structures
- PVA moulds
General printing guidelines *
Nozzle size: ≥ 0.15 mm Height layer: ≥ 0.1 mm Experience level: Expert Print temperature: ± 200 - 230 °C * Fan speed: 0 - 30% Heated plate: ± 65 - 75 °C Closed chamber: Not required * The above settings are guidelines for finding optimal print settings. These ranges should work with most printers, but you can experiment outside these values if considered suitable for your printer. There are many different types of printers, hot-end and offset, so it is difficult to provide universal settings that apply to all.* Do not exceed a printing temperature of 230 °C for extended periods.* After the BVOH has been opened from its original vacuum packaging or used for some time, it is recommended to dry the material before re-use.Filament length

Printing with support materials is generally not plug-and-play and requires some experience in 3D printing, as there is no universal setting for all printers for multi-extrusion printing with PVA and/or BVOH filaments.Optimal settings may also vary between printers of the same model.One of the most common challenges is to achieve good adhesion between the substrate material (PVA or BVOH) and the main print material. The following parameters are essential to achieve good adhesion:- Check the extrusion distance between the printed object and the backing material.
- Usually the default value in slicer software is 0.1 - 0.2 mm, which is optimal for mechanically removable substrates. For water-soluble media, we recommend setting this value to 0.0 mm.
- Ensure that the indicated nozzle temperature is accurate.
- If the temperature deviates by 10°C or more from the set temperature, the media flow may be impaired. The extent of the variation depends on the printer used.
- Check that the printer is correctly levelled. Avoid height differences between the various nozzles.
- To check for correct nozzle alignment, we recommend printing a small bar (e.g. 5 cm × 1 cm in PLA) and changing nozzles every 1-2 layer to detect any imperfections in the layers.

- Questions(FAQs)
L'ASA è il materiale consigliato per l'uso esterno. A differenza dell'ABS, l'ASA è altamente resistente ai raggi UV, non ingiallisce e mantiene le sue proprietà meccaniche anche sotto l'esposizione diretta del sole e degli agenti atmosferici.
Il PETG è un materiale molto viscoso. Per ridurre lo stringing, è fondamentale calibrare correttamente la temperatura di stampa e la distanza di ritrazione. Inoltre, assicurati che il filamento sia asciutto, poiché l'umidità assorbita peggiora drasticamente questo fenomeno.
In generale è sconsigliato, poiché ogni resina ha tempi di esposizione e composizioni chimiche differenti. Mescolarle potrebbe portare a fallimenti di stampa o a una polimerizzazione incompleta del pezzo.
La resina liquida è considerata un rifiuto speciale. Non deve mai essere gettata negli scarichi domestici. È necessario polimerizzare i residui liquidi (esponendoli al sole o a lampade UV) fino a renderli solidi, dopodiché possono essere smaltiti seguendo le normative locali sui rifiuti plastici speciali.
