Soluble support structure can be used with any extruder-based 3D printer

Soluble support structure can be used with any extruder-based 3D printer

One of the issues with extruder-based 3D printing is that it can be very difficult to print objects that have voids in them. You simply must have something to deposit the soft material on until it has a chance to harden. [Matt] found a solution which should work for any extruder-based printer (with one caveat we’ll get to in a minute). He prints a support structure out of HIPS then later dissolves it using Limonene . The image on the left shows the object soaking for 24 hours. The final project is seen beside it.
