Helios Support is a water-soluble PVA (polyvinyl alcohol) support material for complex multi-extrusion 3D printing with styrene-based materials, or thermoplastics that need to be 3D printed at elevated temperatures. Helios Support is a 3D printer filament with excellent thermal stability that can be 3D printed at nozzle temperatures up to 250° C. This makes Helios Support an ideal PVA support material with good thermal and chemical adherence to Styrene-based filaments and other materials that need to be 3D printed at higher temperatures.
- Good solubility in lukewarm water
- Circulating water will speed up the dissolvability process
- Excellent thermal stability, resulting in minimal risk on deterioration/crystalizing inside the nozzle
- Max thermal stability of 250° C, tested up to 256 seconds with no flow
- Can be printed in heated build chambers up to 60° C
- Biodegradable once dissolved in water
- Safe dissolution in tap water
- Can be disposed of in the kitchen sink, or household drain with an excess of water
- Good bonding to Styrene-based materials and other (thermo)plastics that print within a similar temperature range
- Good adherence to ABS, TitanX, ClearScent ABS, ApolloX, Crystal Flex, Python Flex and Volcano PLA
- Reliable multi-extrusion 3D printing of complex structures that require a water-soluble support material
- 3D printing geometries with large overhangs, or complex hollow structures
- PVA Molds
General printing guidelines *
|Nozzle size: ≥ 0.15mm||Layer height: ≥ 0.1mm||Experience level: Expert|
|Print temp: ± 235 – 255° C *||Fan speed: 0 – 30%|
|Heat bed: ± 65 – 75° C||Enclosure needed: No|
*) Above displayed settings are meant as guidance to find your optimal print settings. These ranges in settings should work for most printers, but please do feel free to experiment outside these ranges if you think it is suitable for your printer. There are a lot of different type of printers, hot-ends, and printer offset that it is extremely difficult to give an overall one-size-fits-all setting.
*) Once Helios Support has been used or opened from its original vacuum-sealed packaging for a while it is advised to dry the material before using again.

*) Please do note that the above-shown PVA compatibility overview is purely meant as general guidance and advice based on our in-house expertise and experience and that it is not to be seen as a fixed principle or rule. There are numerous factors that determine the best fitting PVA support with primary building materials and it actually varies per 3D printer. Below overview can, according to our current state of knowledge, be used as guidance for the vast majority of 3D printers.
General guidance for printing with PVA support materials
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 are to establish a good bond between the PVA support material and the primary building material. Below parameters are of utmost importance to establish 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 actual 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.
