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.

Hi Jos,
ReplyDeleteGreat to see this comparaison, would you mind to talk about the tolerance/precision difference please?
I have not assembled this "SLA" extruder, so I can not say if it is stronger.
ReplyDeleteI think as for dimensions the SLA will be more precise.
But it is still plastic that can deform under stress, so there are some tolerances already build into the design in the first place.
