How do you calculate extra infill?

I think the minimum assumed by the 3DHubs calculator is 20% right?

So what if a user wants a 100% infill print?

How do you surcharge (calculate) this?

Thanks!

I think its actually 25% and 3 outlines.

Use your slicer program, using print weight of material then convert that to volume by dividing estimate weight with the density of material(although this is dependent on what you are telling the slicer the density is)

Heres an example using abs with a density of 1.04 grams per cm3. I have my slicer set with density of the 1.04 and it estimates the print weight to be 100g. so 100 divided by 1.04 equals 96.15cm3 volume.

Close! 25% infill and 2 shells

Thanks for helping out Keebie!

This document says 3 outlines DocSend

Hi @en3DStudios_com, as @keebie81 said, it’s probably easiest if you do your own calculations based upon your slicer report. Simplify3D reports a cm3 volume for a print, so you could simply multiply that by your quoted cost per cm3 in your printer settings, then adjust the total of the order accordingly.

My mistake, 3 outlines is correct.

Thanks again Keebie!

Hmm that’s strange, I used to remember that the default was 20% infill with 2 perimeters.

I didn’t know it had changed to 3 perimeters (1.2mm wall thickness) and 25% infill.
