Product Description

Why is it important to use support material during 3D printing?

Support structures act as vital auxiliary materials in 3D printing, specifically needed to print tricky overhangs and bridge features in your model.

How do you combine water-soluble PVA with other materials during a 3D print?

If your 3D printer has two extruders, you can assign one to PLA for printing the actual model and the other to a dissolvable material such as PVA or limonene-soluble filament for the support structures.

What are the pressure parameter settings for using PVA filament as support material?

Printing temperature: 190-200’C (recommended temperature 200°C)

Bed temperature:55-65°C

Fan speed: 100%

Print speed: 20-40mm/s (recommended 30mm/s);

Recommended Heated Build Platform: Structured Paper, PEl

Is it possible to fully dissolve a model printed with water-soluble PVA filament in water?

The model’s support structure softens at around 60°C and can be manually removed. Note that it does not fully dissolve in water.

What filaments work well when printed together with PVA?

Most standard 3D printing filaments, including PLA, PETG, PA-CF, ABSand TPU, can be used in combination with water-soluble PVA

【Please note】YOUSU PVA filament is not soluble in water, but it softens at 55-60°C water temperature, so that the support can be easily removed. If you want a PVA filament that is completely soluble in water, please do not buy this product. If your main purpose is to remove the support more easily and you do not care whether the PVA is completely melted in water, then YOUSU PVA filament is your ideal choice.
【PVA filament】YOUSU PVA filament has good thermal stability and is ideal for printing complex models. Such as large overhang supports, deep internal cavities or complex geometries. PVA support material can completely liberate the difficulties encountered in internal support removal. The support structure can be easily removed by simply immersing the model in water, and it is no longer necessary to assemble it from individual parts.
【Water-soluble PVA filament】Water-soluble PVA is a water-soluble polymeric organic compound. Environmentally friendly, non-toxic and odorless. It is delaminated by softening and then manually peeled off without damaging the printed surface.
【High Compatibility】YOUSU PVA filament is perfectly compatible with most 1.75mm FDM 3D printers. PVA 3D printer filament has excellent interlayer adhesion and can have good adhesion with filaments such as PLA, TPU, PVB and nylon.
【Recommended Print Settings】PVA filament 1.75mm, dimensional accuracy +/- 0.02 mm, 0.5 kg/spool (1.1 lbs). Recommended nozzle temperature 190°C – 210°C, hot bed temperature 55-65℃, printing speed should not exceed 30mm/s.
【Packaging and Support】Yousu 3D printing PVA filament is vacuum sealed and desiccant is added to protect the filament from moisture. However, it is still recommended to dry it before printing to obtain the best printing experience and effect. At the same time, Yousu provides 3D printing related matters and manual technical support.
