Soluble support materials enable complex geometries, clean surfaces, and less post-processing. But which 3D printer under $1,000 is really suitable for this? In this article, you will find a sound assessment, practical tips, and our recommendations from everyday testing.
What is soluble support and what advantages does it offer?
Soluble support consists of special filaments that dissolve in water or a solvent. This makes it easy to expose even complex structures without mechanical post-processing.
"Soluble support saves time, reduces the risk of damage, and enables geometries that would be difficult to achieve with conventional support structures."

Which 3D printers under $1,000 are suitable?
Not every 3D printer with a dual extruder is automatically suitable for soluble support. A reliable two-material printing unit, good slicer support, and stable print quality are important.
| Model | Price (approx.) | Extruder | Compatible Materials | Features |
|---|---|---|---|---|
| Bambu Lab P1S | $699 | Dual Extruder (AMS) | PLA, PETG + PVA | Reliable, easy to use |
| Prusa MK4 | $799 | MMU3 (Dual Material) | PLA, PETG + BVOH | High print quality, strong community |
| Creality K1 Max | $749 | Dual Extruder | PLA, PETG + PVA | Large build volume, high speed |
5 Tips for Successful Prints with Soluble Support
- Choose a suitable material combination – e.g., PETG + PVA or PLA + BVOH.
- Configure the slicer correctly – optimize distance, support density, and interfaces.
- Avoid enclosed parts – so that the solvent can reach everywhere.
- Be patient during dissolution – depending on the material, it can take several hours.
- Clean thoroughly after dissolution – for perfect surfaces.
Practical tip
Use lukewarm water and stir gently to speed up the dissolution process. An ultrasonic bath can help with stubborn residues.
Frequently Asked Questions about Soluble Support
Which materials are suitable for soluble support?
PVA and BVOH are the most common, as they dissolve in water. PVA pairs well with PLA, while BVOH also adheres well to PETG. HIPS is often used for ABS and ASA, as it dissolves in limonene.
How long does it take for the support to dissolve?
This depends on the material, quantity, and water temperature. Small parts are often free after 2–4 hours, while larger support structures may need overnight. Lukewarm water, movement, and regular water changes significantly speed up the process.
Can I also use soluble support with affordable printers?
Yes – the printer must be able to process two materials, meaning a dual extruder or a multi-material system. With a simple single extruder, soluble support can only be used to a very limited extent.
Which is better: PVA or BVOH?
BVOH dissolves faster and adheres to more materials, but it is more expensive. PVA is cheaper and completely sufficient for PLA prints. Both materials should be stored dry, as they absorb moisture from the air.
