Just Married-Award (dual extrusion)

thingiverse

Friends of mine just got married. I designed them a neat little reminder with the date of the event on the bottom side of the stand, hoping they'll remember the wedding day in a few years. But if they forget, well, it's not my fault! Update 23.02.2017: Thanks to help from the community and calibrating my printer, I was able to print this neat little gift again, and it turned out great! Unfortunately, the rings came apart, and I had to glue them back on top of a new stand. But when they got their present, it was worth it! Check out "I Made One" for more details. This is one of my first dual-extruded prints. As you can see in the post-production pictures, I'm not happy with the result. Main Issues: 1. Oozing: The golden filament contaminated the white stand. Despite using an ooze shield, color fragments still appeared on the stand. Should I print it separately and glue it together afterwards? 2. Connection between stand and rings looks horrible. Was the extruder with gold filament (extruder 2) not primed? Is there a gcode script issue? 3. Bottom area of the rings (big overhang) are ugly. No supports were possible, or the white stand would become more contaminated with golden filament. 4. Lots of strings. Should I increase retraction? 5. Insufficient bridging. Could better cooling or faster movement while bridging solve this problem? Any ideas? Please share them in the comments, and let's improve this thing! Print Settings: Printer: Geeetech Prusa i3 Pro C Rafts: No Supports: No Resolution: 0.2mm Layer Height Infill: 5-20% Notes: Slicer used: Simplify 3D Process 1: Stand (White) Process stops at 10mm 5% infill 3 layers (bottom, top, perimeter) First layer: 210°C / 70°C Other layers: 200°C / 60°C Ooze shield: Offset: 2mm Outlines: 2 Waterfall Process 2: Rings (Gold) Process starts at 10mm 20% infill 3/5/5 layer (bottom, top, perimeter) First layer: 220°C / 70°C Other layers: 210°C / 60°C Ooze shield was also activated, but didn't appear in the slicing preview Post-Printing: I used my cutter and Proxxon to drill/cut most of the unwanted strings away. However, I'm still not happy with the result. The ooze-shield caught some filament, but not enough. The stand is contaminated. After cutting a bit, the numbers are readable. At the bottom of the rings is a big overhang, so my printer had problems. (Front) The bottom of the rings look very messy. (Back)
