@Matterthings José,
My calculations above show a real world operational cost for my hub operation. I believe I’m overpriced even at $.10 per cm3 as the calculations show I can make a profit in equipment and dollars at prices as low as $.05 per cm3.
The calculations from my other post below which I will expand upon here show that the CURRENT BASE PRICE already implemented by 3D Hubs is currently to high and may stifle future free market competition allowing another platform to encroach upon 3D hubs service.
Filament:
Recycled water bottles and other household plastics.
$0.00 per cm3
*It is important to note that the cost of filament could run into negative territory. If someone sets up a recycling center or sets up shop at a recycling center they could theoretically charge a small fee to recycle plastics which would yield them a negative cost per cm3 of filament.
Electric:
Solar or hydro power utilized for a home or another business.
$0.00 per hour (cost is written off for another entity)
Printer Depreciation:
Using modular design and true reprap philosophies the depreciation of a home made printer can easily reach less than 1% per month. Upgrades and new printers could be purchased for very little ($65-$100 using direct from china electronics and 3D printed parts)
Hourly or per CM3 cost of around $.005
3D Hubs Service Fee
Student Discount: Not offered to keep prices lower.
Labor and Profit: If this is a part time or ancillary business venture the printer would operate in an existing shop and simply bring in extra revenue. Very slim margins would be needed.
This scenario, which is not far fetched, would result in a per cm3 cost below THE CURRENT 3D HUBS FORCED BASE PRICE of $.01 per cm3 and $1 per order.
I would be willing to invest some money into a hub who wishes to operate this way and offer sub $.01 per cm3 prints.
