40W is previously enough to soften aluminum sizzling ends, so 50W doesn't Permit you to print any further plastics. The only real Ceramic Heater Tube for 3D Printing gain is actually a shorter heat-up time.
Keep in mind that the method that defines the output ability of the heating element is P = V2/R, where by P is the warmth output in Watts, V
The different wattages of hotend heaters all have their unique positives and negatives. So it is actually a good idea to Evaluate them and find out what Each individual provides to your table.
A secondary benefit is they heat up more quickly than a 30W cartridge. But it is not a big change and you may perhaps however should anticipate the heated bed for getting as many as temperature anyway.
