comparison between SLA and FDM





Recently I compared my FDM printed extruder to the same extruder printed with an SLA machine.
As any one can guess (without even looking at the photo`s) the SLA part was much more beautiful then the FDM counterpart.

But then I did the math thing (money wise)

Get the results after the break


 SLA machine (Objet24)

raw material                 90 Grams                          4,09
machine depreciation    4EUR/Hour x 11               44,00
electricity                     0,7KWh x 11 x 0.22            1,69
Man hour                      5min x 0,5                         2,50

total                                                                     52,28 EUR

FDM machine (Cartesio at 0.25mm layerheight)

raw material                  60 Grams                          2,80
machine depreciation     0,27EUR/Hour x 2,5          0,68
electricity                      0,18KWh x 2,5 x 0.22        0,10
Man hour                      5min x 0,5                         2,50

total                                                                     6,08 EUR


The costs to make the part were 8,6 x more for the SLA part then for the FDM part.

the question is:
Is the SLA part 9x more beautiful then the FDM part ?
That is a question that each will have to answer for themselves.


1 more useful fact:
the machine depreciation of both machines was set to 9000 hours


If you have other numbers to fill in, please let me know.
