Soluble Supports from PVA filament with single extruder

3D printed supports may be hard to remove from main object. In my previous two videos I demonstrated manual multicolor 3D printing and now I am using same technique to print supports in soluble PVA. This means if I put object in water, supports will dissolve from the object. It is practical only with horizontal or near horizontal contact surfaces between object and support. In this video I am using PrimaSelect PVA+ material, it is expensive filament (50€/500g) but only contact layers has to be printed with this substance. Used software and hardware: Fusion360, PrusaSlicer, Prusa MK3 3D printer, PrimaSelect PVA+, Gembird PLA Contents: 0:00 Introduction 2:40 Test 1 (horizontal surface, custom supports) 10:05 Hook test (how fast will dissolve) 10:52 Test 2 (letters, horizontal contact, custom supports) 16:29 Test 3 (curved surface under angle, custom supports) 20:34 Test 4 (STL file, supports generated by slicer) 26:35 Conclusions Link to my previous two videos about manual multicolor 3D printing:    • Two color 3D printing with single extruder...      • Multicolor 3D printing with single extrude...   My "to do" checklist for PrusaSlicer: For custom supports: Open PrusaSlicer: Load main STL Add Part, load second STL Print settings / Select Layer height Printer Settings: General / Extruders: 2 Custom G-code: Tool change G code: M600 Extruder 1: Retraction when tool is disabled: 1mm Extruder 2: Retraction when tool is disabled: 1mm Print Settings: Support Material: Contact Z distance to 0 Multiple Extruders / Enable Interface shells Plater: Change Filament (second extruder) to PrimaSelect PVA+ Change Extruder from default to 1 and 2 (for loaded STL objects) Slice Now (to see Number of tool changes) Print Settings Multiple Extruders / Disable Wipe tower Slice Now and preview the printing. For automatic supports generated by PrusaSlicer: After opening PrusaSlicer: Load STL Print settings / Select Layer height Enable Supports Printer Settings: General / Extruders: 2 Custom G-code: Tool change G code: M600 Extruder 1: Retraction when tool is disabled: 1mm Extruder 2: Retraction when tool is disabled: 1mm Print Settings Support material: Reduce Overhang threshold to your minimum overhang angle (example 30 = 60° overhang angle) Support Material: Contact Z distance to 0 Support Material: optional: change the interface layers to 2 or 1. Multiple extruders / disable Wipe tower Multiple extruders / Support material/raft interface extruder to 2. Platter: For Extruder 2 change filament to PrimaSelect PVA+ Slice Now and preview the printing.
