Example Build Settings

[sam598]

Your build settings are going to be different based on your print, filament, and how many pieces you are printing at a time. These are the settings I used that resulted in a successful print, and some issues I found while finding these settings. They may be useful to you, or someone may have better suggestions.

Printer: Makerbot Replicator 2

Layer Height: 0.2mm/200micron

Filament: Black PLA
In my experience I find this color best for printing parts that need to be precise and solid.

Infill: 5%
There seems to be an 7% time savings vs 20% infill and no real difference since the majority of the prints are thin.

Infill Pattern: Diamond Fill Fast

Shells: 2
The print appears airtight, more shells would potentially add extra security, but there is an additional 7% in time savings by printing 2 shells compared to 3.

Roof Surface Thickness: 1.4mm
The first print I made was at 0.8mm and had several holes inside the mask. adding additional layers covered these holes. additional infill may also alleviate this issue.

Floor Surface Thickness: 1mm
Same reasoning as the roof surface, but does not need to be as thick.

Fixed Shell Start: Disabled
By having the shell start at a different position each layer, it prevents a continuous seam line from forming which can sometimes cause a hole to appear. This insures that the seam line on a previous layer will always be printed over, and fused together.
