Now you can have your very own Imperial Star Destroyer! This is a very long and challenging print; it took me about six hours with 0.2 mm layer height, 30 mm/sec perimeters and 50 mm/sec infill. Try it in silver PLA for that authentic Imperial feel!
Print one Star Destroyer Plate and one Stand. The three pieces on the plate are also supplied individually. Glue the top and bottom together, and the engines to the back.
This model really demands an 8 inch or larger build platform so it can be printed nice and big for maximum detail, but Makerbot, Mosaic, and Huxley operators can scale it down to about half size and it will come out fine. To get good detail, you'll want to print this with a very low layer height; 0.2 or less is recommended if printing it at full size; 0.15 or lower is recommended if printing it at half size. Additionally, to get Skeinforge to not print it entirely solid, you'll most likely need to temporarily make three changes to your profile:
- Disable Carve > Infill in direction of bridge
- Increase Fill > number of extra shells to at least 3
- Decrease Fill > Solid surface layers to 1
Next, you will need to use support material so that the command bridge will print properly:
- Set Raft > support material to "Everywhere" (set Everywhere to True and None to False)
- Increase Raft > Support Minimum Angle (degrees) to 65
The stand should be printed with 100% infill and 0 extra shells.
Here are some other handy tips:
- The two halves need very good build platform adhesion or else they'll warp and not line up properly. A level build platform is crucial. Heating helps too although I've printed on blue painter's tape with enough care.
- Turn off the Cool plugin or else the apex of the bottom part probably won't come out well. Instead, use a fan to provide some active cooling.
- With the layer height set to 0.15 or below, you'll probably need to adjust your width over thickness for infill and perimeters or else the extruded plastic will have a tendency to be too sparse for the bottom layer.
- Hexagonal infill seems faster than Line infill for this model. It's a long print anyway; you'll appreciate the speedup!
