Re: Delta Heated Chamber Preparations!

Take this for what its worth because I'm a newbie to delta printers but I have about 10 spools worth of experience printing ABS on a Cartesian printer and I've tried about every combination of heated bed with ABS slurry, hairspray, glue stick, enclosure, etc.

You don't need a heated chamber to successfully print ABS warp free. A simple enclosure to keep out drafts combined with a layer of purple glue stick over your heated glass bed is enough to keep literally any print from warping in my experience. I have printed 8+ hour objects that take up my entire print bed with sharp small corners and no brim and gotten no warping with this method. Choose a powerful (200+ watt is nice) heated bed and make sure your power supply is up to it, bridging the outputs if needed. Also, I use a RUMBA which has a separate input and output for the heated bed. I let mine heat to at least 80 C before starting a print and it is usually up to 100 C after 15 minutes of printing. Make sure your enclosure is complete, including the top. I just use plexiglass, weather stripping and magnets on mine, I have not seen the need for any cork insulating. I tried hairspray on the bed for a while, but once I discovered elmers purple glue stick, I got much better results and my hairspray is never used anymore.

Your results may vary, but I think one reason you are not finding a lot of info for heated chambers out there is that you probably don't really need it to get quality ABS prints.
