PolyDissolve™ S1

PVA-Based, Water Dissolvable Support PolyDissolve™ S1 is a PVA-based filament engineered to provide water-soluble support for PLA, TPU, PVB, and Nylon-based filaments. It forms a perfect interface with these materials, offering strong support during printing and dissolving cleanly in water for easy post-processing.

Optimized Compatibility and Solubility Specifically designed for use with Polymaker’s PLA, TPU, PVB, and Nylon filaments, PolyDissolve™ S1 displays excellent solubility and is ideal for intricate prints with complex overhangs and internal structures.

Dissolving and Post-Processing Supports typically dissolve in 6–12 hours. Dissolution can be sped up by increasing water temperature, changing water regularly, or adding water movement.

Ideal for Multi-Material and Complex Prints Choose PolyDissolve™ S1 when you need reliable, easily removed water-soluble supports for detailed, multi-material 3D printing projects.

Print Tips

This material is a PVA material that is dissolvable in water meaning you can use it for very complex geometries or previously impossible prints. PolyDissolve™ S1 will work for PLA, TPU, PVB and Nylon based filaments from our portfolio. It is specifically engineered to have a perfect interface with these materials while also displaying good solubility.

• Though it is possible to use PolyDissolve™ S1 with a single nozzle, it is not recommended due to increase chances of clogging when swapping materials. This is particularly true if using PolyDissolve™ S1 with a material that has a different print temperature, such as one of our nylons. IDEX or ToolChanger is recommended.

• PolyDissolve™ S1 is a very hygroscopic material, meaning it absorbs moisture very easily. This means it is very important to keep dry. You should use a heated filament dryer on the lowest setting for the entirety of your print.

• If you hear any "popping" or "cracking", or you see the filament bubbling up when extruded, you need to dry the material.

• You need to print PolyDissolve™ S1 very slowly - we recommend no higher than 60mm/s or 8mm^3/s max volumetric speed.

• PolyDissolve™ S1 will dissolve quicker if you are using warm water that is moving. The quickest way to dissolve is to use boiling water, though you would need to make sure the parent material can support such high temperatures. One method is to place your part in a tub of warm water, place it on a heated bed slinger build plate, and then run a g-code that will rattle the build plate back and forth. The higher the temperature of the water and the more it flows, the quicker it will dissolve.

• It is also recommended to change the water every few hours so that it will dissolve quicker.

FAQ

What material can PolyDissolve™ S1 support?

PolyDissolve™ S1 can support PLA, PVB, TPU and Nylon based materials from our portfolio.

How long does it take for PolyDissolve™ S1 to dissolve?

It can take 6-12hours to fully dissolve depending on your setup. You can speed up the process: - By increasing the water temperature - By changing the water regularly - By adding a pump to make the water flowing

Will the spools work in an AMS?

Yes! We have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS.

That said - we will always recommend using a multi nozzle extruder when printing with more than one material type to help prevent clogs.

It is possible to print a material and PolyDissolve out of a single nozzle but you need to make sure you properly purge all of the previous material when swapping. IDEX or Tool Changer recommended.

Is this material food safe?

Unfortunately we do not have any data whether this material is food safe. As of now, no 3D printing material on the market is FDA food safe compliant. This is because in order to be certified as food safe, the actual object needs to be certified and not the base material. The shape, bed used, environment the object was made, and much more goes into getting a food safety certificate. As of now there is no real certification that the FDA offers for 3D printing.

Do you sell refills?

We are sorry but we do not sell refills at this time

Is this material recyclable?

Unfortunately there is no great answer for recycling PLA at this time. Our cardboard spools are biodegradable but there is no great way to recycle PLA at this time.
