Embedded 3D Printing with Liquids on a Bricked Prusa FDM Printer

Recently [Riley] got his paws on an old Prusa i3 FDM printer that had clearly seen better days, with a hot-end that had suffered an explosive blow-out. For the project he had in mind this was of course perfect, as his intention was to replace the hot-end with a syringe system for embedded 3D printing (E3DP) , which uses a supportive medium to allow for the printing of materials and structures that would be impossible with just air. Generally in additive manufacturing (AM) methods like fused depo
