Help Me Decide!

You clicked this link because you are not sure which settings to choose for your print.  Keep reading for a breakdown of the different options you can choose and how they will affect your part’s aesthetics and function.


Infill is a description of how much of the inside of the print is solid plastic.  Typical settings are between 10-30%.  This means that, of a given internal volume, 10-30% of it is filled in with plastic.  For almost all prints, infill of 20% will be more than sufficient.

Wall/Outline Count

This setting determines the number of walls, or outlines, that the printer makes before printing the infill.  Typical settings are 2-3 walls.  Contrary to what one may think, It’s been shown that the number of shells determines the overall strength and rigidity of the print by a much larger magnitude than infill.  If you’re looking for an extremely strong part, 4-5 walls will most likely give you what you want.


A 3D printer works by depositing one layer at a time, slowly building up to the full size part.  As you can imagine, the height of the layer determines how smooth edges are, and how much detail can be seen in the final print.  For most prints, a resolution of 0.2mm is considered ideal, as it provides a good compromise between print time and detail.  If your part is mainly a structural piece and detail is not important, a lower resolution such as 0.3mm can reduce print time and as a result the cost of getting it printed.  Finer resolutions such as 0.1mm or even 0.05mm can also be done if you are needing extreme detail and smooth edges, but keep in mind that print time and cost will go up, inversely proportional to the layer height.  For example, a part printed at 0.2mm might cost $20, but at 0.1mm, it would be more like $40, due to it taking twice as long.

That’s it!  These three options are the most important ones that will determine the strength, detail, and cost of your print.  Click HERE to go back to the Get a Quote page with your newfound knowledge!
