SOLUBLE support structure CAN BE utilized WITH any type of EXTRUDER-BASED 3D PRINTER

one of the problems with extruder-based 3D printing is that it can be extremely challenging to print objects that have voids in them. You just should have something to deposit the soft material on up until it has a possibility to harden. [Matt] discovered a service which ought to work for any type of 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 utilizing Limonene. The picture on the left shows the item soaking for 24 hours. The final job is seen next to it.

The only genuine issue with this method is that it needs a second extruder. because printers develop objects by layers, changing material in a single print head isn’t an option. HIPS means High-Impact Polystyrene. It extrudes at the exact same temperature as the ABS (235C) as well as adheres well to a heated bed kept at 115C. ABS will be unaffected by the hydrocarbon solvent Limonene, except for the residual odor of citrus.
