Question 1

How much does it cost to 3D print something?

Accepted Answer

Most hobby prints cost between $0.20 and $5.00 in materials. A typical 50g PLA print uses about $1.00 in filament and $0.05-0.15 in electricity. Electricity is usually under 10% of total cost.

Question 2

How much electricity does a 3D printer use?

Accepted Answer

Most desktop FDM printers draw 100-250W during printing. A 4-hour print on a 200W printer at $0.15/kWh costs about $0.12. Heated beds account for most of the draw.

Question 3

Is 3D printing cheaper than buying parts?

Accepted Answer

For custom, one-off parts — yes, almost always. A replacement bracket that costs $15+ online can be printed for under $1 in filament. 3D printing shines for custom fit, rapid iteration, and parts you simply can't buy.
