Frequently Asked Questions

How much electricity does the Two Trees SK1 use per hour?

The Two Trees SK1 consumes an average of 140 Watts while printing. Operating it for 8 hours uses approximately 1.12 kWh, costing roughly $0.18 at standard rates ($0.16/kWh).

Why does peak power reach 350W during warmup?

During the initial 3 to 6 minute warmup phase, the heated bed and hotend run at 100% duty cycle to reach target temperature as quickly as possible. Once stabilized, power drops to the ~140W average.

How much power does the SK1 use when idle or in standby?

When powered on and in standby (display on, mainboard fans idle, heaters off), it consumes roughly 5W to 15W of background electricity.

Can the SK1 run on a UPS battery backup or portable power station?

Yes. Because average running draw is only ~140W, a standard 500Wh portable power station or 1000VA UPS battery can easily sustain printing for 3 to 5 hours through power outages.

Does printing ABS or ASA with a 100°C bed increase electricity cost?

Yes. Maintaining a heated bed at 100°C-110°C for engineering materials requires more continuous thermal power than printing PLA at 60°C, increasing average power draw by roughly 40W to 80W.
