As title. I'll need a 400mm x 400mm heating pad for the printer I'm planning. I'll be using 24V DC power. I can get a 24V 450W silicone heater. Will this be sufficient or should I go the AC mains / SSR route? The bed will be well insulated and I'll be using an aluminium heat spreader but probably with a removable glass print surface on top. Thanks.
