How to set up PVA+ Filament for Printing

Raise3D Premium PVA+ (Polyvinyl alcohol) is a water-soluble 3D printing material with strong adhesion when paired with PLA, PETG, Nylon, etc., making it an ideal support material for various types of filaments. The PVA+ supports dissolve when immersed in water, leaving behind a smooth interface surface on the 3D printed part. For more information on Raise3D Premium PVA+ filament, please visit Raise3D Premium PVA+.

A. Precautions for storage and use of PVA+ consumables

PVA+ is a hydrophilic filament, which means it absorbs moisture from the air easily. When you unpack the PVA+ filament, it is easily to get wet. Please store the PVA+ filament together with desiccant in an airtight container. It is recommended that you can use the Raise3D Filament Dry Box.

If your PVA+ filament absorbs moisture and becomes wet, the filament will become soft and sticky. When printing PVA filament, hissing and popping noises will occur and the model will warp, have bubble, get stringing, and even block the hot end. To get a totally dried PVA+ filament, you need to use a drying oven to dry it at 80°C for 6-8 hours. The exact drying time and temperature will vary depending on the brand you use and how wet the filament is.

B. Hardware Requirements

The table below is the recommended hardware requirements for printing Raise3D Premium PVA+ filament, please follow the table below to set up your printer for the best print quality.

C. Load the filament

1. PVA+ is specially developed for dual-printing, so it is often used to for printing support and Raft matching other filaments. When you print with PVA+ filament, you need to load the PVA+ filament into the right extruder of the Pro3 series printer.

2. Before loading the PVA+ filament, please dry the PVA+ filament in a drying oven at 80°C for 6 hours.

3. Before loading the PVA+ filament into the Pro3 printer, please put the PVA+ filament in the dry box, and then load it to the printer to keep it dry. The PolyboxTM is used in this tutorial to place the PVA+ filament. Place the desiccant in the PolyboxTM along with the PVA+ filament.

Wait for the humidity to drop below 15% before loading. For more information about PolyboxTM, please visit https://www.raise3d.com/products/polybox/.

4. Two feeding ports are reserved on the right door of the Pro3 printer, you can place the drying box near the Pro3 series printer, and then load the filaments from the feeding port into the right extruder. If the length of the tube is not enough, please use a longer extension tube for the transfer.


The guiding tube needs to be sealed and inserted into the feeding port throughout the process to ensure that air cannot enter the drying box and the guiding tube.
If the filament is loaded directly into the right extruder through the right filament run-out sensor, the right filament run-out sensor must be turned off. Because the filament run-out sensor adopts photoelectric detection, it can only detect non-transparent filaments. PVA+ is a transparent filament, so it can't be detected. The printer will automatically suspend printing during printing.

5. You can also place the drying box near the extruder feed port and load the filament directly into the right extruder. The feed tube must be smooth, straight and free from kinks or bends.


If the filament is not loaded into the right extruder via the right filament run-out sensor, the right filament run-out sensor must also be turned off. When printing, if the filament run-out sensor cannot detect the filament, and the printing will be automatically suspended.

6.Please click the setting button to enter the setting interface, and then click "Machine" > "More Settings" > "Advanced Settings" > "Filament Run-out Sensor" to turn off/on the right filament run-out sensor.

7.For how to load filaments into the extruders, please refer to Pro3 Series-How to Load and Unload the Filament-V1.0.

D. Calibrate Nozzle Height and X/Y Offset

1. Before trying to print with Raise3D PVA+ filament, please calibrate the nozzle height and X/Y offset of the Pro3 series printer to ensure that the printer can print two colors normally.

1)     1) How to calibrate the Nozzle Height, please refer to: How to Calibrate the Nozzle Height.

2)     2) How to calibrate the X/Y offset value please refer to: How to Calibrate the Right Nozzle XY Offset.

E. Set the parameters of PVA+ printing in ideaMaker

1. Open ideaMaker. Make sure you have downloaded the latest ideaMaker. If you haven't downloaded ideaMaker, please visit https://www.raise3d.com/download/ to download the latest version of ideaMaker.

2. Click the "+" button to import the .stl file.

2. Click the “Start Slicing” to start slicing. You will enter the interface to select a slice template.

3.Make sure you have selected the Pro3 series printer in the "Printer Type". ideaMaker has preset slicing templates with various precisions for various filaments, please select the filament for your left and right nozzles. Here, for example, the left nozzle is loaded with Raise3D PLA filament, and the right nozzle is loaded with Raise3D PVA+ filament. Then select a slicing template according to your needs, for example, here we select the "Standerd-Pro3-PLA" slicing template.

Note: PVA+ filament can only be loaded into the right nozzle.

4.When you specify the right nozzle to print PVA+ filament, ideaMaker will automatically modify some settings to get better PVA+ printing effect. This feature will disable some settings under the Advanced Settings and cannot be edited directly. If you need to edit these settings, there are 2 methods to edit the settings of PVA+ filament.

1) Method 1: On the "Select Template" interface, click the setting button on the right side of PVA+ filament to enter the filament setting interface. Here, you can set the parameters of PVA+ filament.

Note: "Override Slicing Settings in Templates Linked to the Filament" is enabled by default for PVA+. When you edit the advanced settings in it, it will automatically cover the related settings in the associated slicing template.

For example, here we select "Raft Only" for PVA+, which will cover the relevant settings in the "Standerd-Pro3-PLA" template. Click the "+" sign to add more advanced settings.

Method 2: Select the template and click "Edit" to enter the edit interface. You can click "Advanced Settings" to enter the advanced settings interface. On any interface of advanced settings, click the pencil icon, and ideaMaker will directly jump to the PVA+ filament setting interface, which is convenient for you to edit parameters.


1) PVA+ filament is usually used for printing support or Raft. When you use PVA+ to print support, please set "Generate Support" to "All" in the advanced settings. In the PVA+ filament setting interface, select the "Support Extruder" as "Right Extruder".

2) When you use PVA+ to print Raft, check "Raft Only" in the PVA+ filament setting interface, and select the "Support Extruder" as "Right Extruder". Do not tick the other types of platform additions, Skirt and Brim cannot be printed with PVA+ filaments.

5.After you finish setting the parameters of the slice template, click "Slice" to slice.

6.After slicing, you can click "Slice Preview" to see whether to use the right nozzle to print support or Raft.

7. Click "Export to Local disk" to save and import the .gcode and .data files to your USB flash drive and then import the print file to the Pro3 series printer for printing.

Note: Filenames with non-Western Latin character sets may not display properly.

F. Printing PVA+ filament

1. Please apply 2-3 layers of Magigoo glue on the build plate before printing to increase the adhesion. Please check the adhesion of the first layer when printing, to make sure the edges are not warped.

G. Post-processing

After printing, you can soak the model in warm water. The water temperature should not be too high, the PVA+ support will fall off automatically.
