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. Tips: 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.
