What power cord does a 3D printer use? Most take a standard PC cord: NEMA 5-15P plug to IEC C13. Ratings, gauge, and the cords for Ender 3, Bambu Lab and Prusa.
Set a 3D printer's voltage switch to 115 V in the US and 230 V only on 200 to 240 V mains. Where the switch is, how to check it, and what a wrong setting does.
Bambu Lab printer voltage: the A1, A1 mini, P1 and X1 take 100 to 240 VAC; the H2D, H2S, P2S and X2D ship as 110 V or 220 V versions. Amps per model.
What voltage do Creality 3D printers use? 100 to 120 V or 200 to 240 V AC in, 24 V DC inside. Ratings, the 115/230 V switch and amps per Ender and K model.
What voltage should a 3D printer be? In the US, 120 V AC; many printers take 100 to 240 V with nothing to set. How to read the label, plus the 24 V DC inside.
How many amps does a 3D printer use? About 1 to 3 A at 120 V: 0.7 to 1.7 A while printing, up to 2.9 A at a 350 W peak, plus the outlet and circuit it needs.
How to add a 240V outlet for a 3D printer: panel capacity, breaker and wire size, NEMA 6 receptacles, the 80% load rule and when 240 V beats 120 V.
AC vs DC heated beds explained with the math: current and resistance at 12, 24, 120 and 230 V, heat-up time, PSU sizing, SSRs and where the losses really are.
