Sold Out - Notify me when back in stock


Helios Support - Formfutura's newest "high heat” water-soluble PVA support material

  • 300g 1.75mm diameter, natural color
  • Engineered as support material for dual extrusion 3D printing in combination with engineering materials which require to be printed at higher temperatures and/or in heated build chambers.
  • Can be printed in heated build chambers up to 60° C.
  • Can be printed at nozzle temperatures up to 250° C without the risk of cross linking and nozzle clogging and adheres extremely well to styrene based materials such as ABS, TitanX, Crystal Flex, and ApolloX, but also to Python Flex and Volcano PLA.
  • Dissolves slightly slower in water than normal PVA, but the dissolving process can be accelerated when using warm and circulating water.

Printing with PVA in general isn’t plug and play and does require a fair amount of 3D printing expertise as there isn’t a generic one-size-fits all setting for dual extrusion printing with PVA materials. The optimal PVA settings can even vary between the same models of 3D printers.

One of the most common challenges is to establish a good bond between the PVA support material and the primary building material. Below parameters are of utmost importance to establish a good adherence.

Verify the extrusion distance between the printed object and the PVA support.

  • The default setting in most slicer software is often set at a distance of 0.1mm or 0.2mm, which works well for break-away support, but not for PVA support.
  • For PVA support materials the extrusion distance must be set to 0.0mm as both materials must really come into contact with each other.

The printing (nozzle) temperature is extremely important and it is advised to measure the actual temperature of the nozzle and to compare this temperature with the temperature set in the print settings.

  • If the actual temperature of the nozzle is, for instance, 10°C lower than the temperature in the print settings it might very well be that the layer of PVA support material is not flowing optimally into the layer of the primary building material. It is often seen that the actually nozzle temperature varies from the print temperature set in the slicing software.

Verify if the nozzles of your printer are properly leveled and have exactly the same height, so that there is no “height difference” when layering the PVA support material on top of the primary building material.

  • In order to verify this it is recommended to 3D print a 5cm x 1cm rod and to print every 1 to 2 layers with the left nozzle and the following 1 to 2 layers with the right nozzle and to repeat this process multiple times. If you notice a non-perfect layering then the nozzles aren’t properly leveled. This process can be done with PLA, for instance.
