Berd Air add on

Postby Hellraizer » Wed Jun 10, 2020 9:19 am


we're printing at work mostly in spiral vase mode but our model have lots of overhangs, so I recently optimized the spiral vase printing speed and I would be able to increase speed by 1/3 if it werent for the model cooling.

The avarage speed before increasing the speed was 30mms but as soon as i go higher than 35 cooling the overhangs become a problem by curling up.

Possible Solution: Berd Air. I succesfully installed it some months ago on my private printer. I found all the parts on ali and even installed the little mostfet chip that converts the fan signal to usuable voltage for the airpump.

I could of course just use and external PSU and voltage controller and have the pump running completly independent from the printer, but I wonder if someone has tried installing a berd air style model cooling solution on his raise machine and wants to share some experiences.

That's pretty cool!
I've been thinking about something similar for one of my other printers.
What pump are you using ? And are you able to control the rate of airflow by PWM?
