I don't quite get the per cm3 pricing. Does it mean per material cm3 or does it mean per part cm3?
For example, if I want to print a cube that is 1L (1000cm3) which is almost hollow with only 50cm3 of material will I be charged for 1000cm3 or for 50cm3?

printedsolid - If you use the makexyz model submission tool, it gives you a price based on the model volume. If you go directly to a maker and ask for a quote, then it's whatever the two of you negotiate.

makerbeck - Second pretedsolid's comment. The automatic quoting is based on volume of the part, assuming it is wateright. It does not account for any support material that might be required based on the geometry of the part. Every build I have done has been via a quote.

fabhappy - It would actually be nice if there was a way to disable automatic quotes on a per-profile basis. Although I have accepted certain automatic quotes, the price is always lower than what I would normally be quoting.

bmmal - I realized you may be talking about something else besides "infill." Are you referring to having a model of a cube that has a thin wall thickness rather than just a cube of material? If this is the case, the stl plugin on makexyz calculates the volume of the manifold between the inner and outer shell. Not the volume of space the cube occupies. A thin wall will likely be printed solid but may require sparse support material for the top surface. The calculator on here does not account for support material.

thingisphere - The quoted price in $/cm3 is based on the total amount of material used for the part. Not the part size or volume. Costs of printing are material costs, time on the machine, and general overhead. These costs collectively are reflected in the $/cm3 quote.

bmmal - Thingisphere, if you do quotes that way that is fine. I however (and I would guess many others), don't because the printed orientation, overhangs, etc can greatly change the amount of support material used as well as the machine time. I don't think many people are providing quotes in a "collective $/cm3" manner.

makelab - Bmmal, would you be willing to provide more detail on the equation you use for quoting? I'd be interested in seeing how you weigh each variable.

bmmal - Basically I run the STL through the slicer, calculate the cost of materials used, then determine a markup factor based on the amount of time. Depreciation and maintenance are almost more important than material cost on a commercial machine. For instance if a print is under a certain time threshold i may mark up 50% of the cost of materials used. But when a print becomes very length the markup increases. This is also important in cases of frequent material switching between model and support which exponentially increases time. A print that uses more machine time for the same amount of material should cost more because you could be printing something else with that time instead.

jms3dprinting - I quote based on material weight, which is close to 1 gram per solid cubic cm of material. So a hollow cube may be less than a solid one, provided the support material is less. Quotes are free but ask for a custom quote and not the default Makexyz one. I can provide the estimate and also tell you the part weight.

star - Per cm3 pricing typically refers to the cost associated with the volume of material used in a 3D print, not the overall volume of the printed part. So, if you want to print a hollow cube that is 1L (1000cm3) in volume, but it only uses 50cm3 of material, you would likely be charged based on the 50cm3 of material used, not the full 1000cm3 volume of the cube https://heictojpg.io
