I have the Ender V3 Plus which has a larger print bed so I decided to print this at 140% scale. Piece number 46 is the longest so that dictates how large you can print. I forgot that scaling is a matter of volume so that turned this into quite the project but the end result was worth it. It took me 651 print hours alone which is more than 27 days, and 8,483.13 grams.
Here are some of the print settings that I found to be best, when prioritizing quality. At first I wanted to find how to use as little plastic as possible, but found that each piece was different so this was causing me to actually use more plastic when I had to reprint. I started by printing Africa and you can see a few imperfect pieces. Once I switched to the below, every piece came out great:
1. Split the model in half, specifically cutting to parts so that you can apply different rules to top and bottom
2. Apply variable layer height so that the bottom half is .32mm and the top half is .12mm. This is a huge time saver without compromising quality
3. Bottom half:
3a. Top shell layers = 3
4. Top half:
4a. Top shell layers = 6
4b. Top surface pattern = concentric
4c. Internal solid infill pattern = concentric
4d. Internal solid infill speed = 20mm/s
5. Global speeds:
5a. First layer speed = 22mm/s
5b. Top layer and internal solid infill speed = 40mm/s
5c. Bridge speed = 10mm/s
5d. All other speed = 60mm/s
6. Infill pattern:
6a. If the piece is generally flat with few triangles, see 6b. If the piece has lots of triangles or sharp angles see 6c.
6b. Set the infill pattern to lightning and increase the infill percentage until the lightning pattern is applied so that any overhang is greatly supported. You can see an example in one of my pictures. Sometimes at lower percentages it tries to apply very minimal support but that will cause bad surfaces. When applied correctly, this infill provides maximum quality while actually using less plastic than the other fills... (Continued)
