Are there any good quality, commercial grade filament dryer around that can reach accurate! temperatures of 80-100c for drying PA filaments?
For personal use at home I have modified a food dehydrator with a PID temperature controller and SSR relay switch. This works really well, reaches 100c and temperature does not fluctuate, but this is nothing I can use for my company, the electrics guy will stone me.
Total cost for AliExpress parts was around 25€ for the PID controller plus SSR plus a cheap 35€ 350W food dehydrator from Amazon, which is basically a vertical hair dryer in a round plastic container. I really don’t understand why nobody is producing something like this with some quality assurance.
Looks good. Alternative for business is some Miele convection oven for around 1000€ that come with pretty good PID controller for accurate temperature. If I set my oven at home to 100°C it will be 100°C without fluctuation. I checked with Type K thermocouple.
