Thank you, seriously, for sharing that. I like your approach.
However, I notice that you only charge 10% for each increase in layer height. I find this interesting, I always feel like if a print takes 4 times as long to print, it should be much more expensive. That is 400 microns takes 1/4 the time as 100 microns, give or take. Would you be willing to share your thoughts on that?
Thanks again!
My machine is just a wooden-framed Prusa i3 I built myself, so I found the extra time spent printing at higher resolutions amounts to a pretty negligible increase in electrical costs, as it draws only 300 watts, roughly. I also don’t want the higher price for higher resolutions to deter people from ordering nicer parts, unless they are really big and the electrical costs starts to become significant. The values are adjustable, so you are free to tweak them to your liking! I should probably add an input for electrical cost so people with more power-hungry machines can make use of my spreadsheet. Thanks for the feedback! I want this tool to be as usable as possible.
Guys I’m pretty sure that 3D Hubs just takes the straight-up volume of the model and subtracts 20% of that volume to get “sliced volume.” Just did the math on a few parts, and that theory is holding true.
