Is there an example of tight coupling between CAD and sliced models?

I am on the hunt for CAD packages which can perform some level of slicing as an inherent model feature, instead of either exporting to STL and then importing into the slicer (a la OnShape) or directly opening the slicer from within the software (a…

60 watt heater into 40 watt heatblock

This might be a dumb question, but can a 60 watt heater be used on a 40 watt unit? Simply put, I was wrong in thinking that more power was simply stuffed into the same dimensions. It extends about 5 millimeters beyond my heating block. Can it be…
