  • This is a very good start. It will have limited effectiveness depending how exactly wet the filament is though, as the diffusion speed of water in plastic is low and it takes time to get the water actually out of the center to the surface to evaporate. The few minutes a filament sits in the inline dryer might be OK for surface moisture but will fail with wetter spools.

    I think the ideal system would be to have a dry box that the heating unit and fan blow into, but then feed the filament out to the printer through a “stove pipe” that acts as the dry box exhaust. This way you’re still drying the whole spool over time but then get that “final blast” to ensure the surface is as dry as possible. Make sure to insulate all walls such that you reduce how much heat you lose as the air passes through.












  • It will not affect system stability, but… Surge protectors do not work at all without a ground wire to drop excess voltage to. Any kind of line voltage disturbance could kill every device.

    Additionally, without any ground wire to pull the housings of devices to ground, the potential for a short to energize the case and then electrocute you is also high.

    additionally additionally, if you have grounded outlets that don’t actually have a ground connection running to them, that means either the wiring system is broken or it was “updated” by an unlicensed hack job who has undoubtedly made numerous more dangerous decisions elsewhere in the circuit.

    If your house is entirely ungrounded you really should have an electrician come update it ASAP. Outlet grounds have been mandatory since 1971. The chances are high that wiring predating that code is still using old cloth-wrapped wire insulation or even knob&tube, both of which are huge fire risks as the insulation is decayed badly by now. It’s expensive to have all new wire pulled but it is necessary.








  • This is true. If you left it in the same environment it would eventually return to equilibrium and the net result would be the same. the key is that the plastic has a limited take up rate of atmospheric moisture. so if you dry it for a few hours, the water migrates out slowly, but then takes quite some time to migrate back in.

    generally people either print from a dryer box or dry filaments immediately before printing.
