This is interesting…
Using my calculation sheet (and now computing electricity cost), I calculated the print cost for a part I created:
On Shapeways it would cost € 31.84 (and takes around 18 days for delivery)
On my Form 1+ it would cost me € 73.72 (keeping labor to an absolute minimum and would take ~6 hours to get it printed)
I really thought my own printer would be cheaper than Shapeways. Of course having my own printer gives me more confidentiality and a speed advantage.
Trade offs…
