Analog heated bed v0.1

Originally posted on Thingiverse.com: Jun 7, 2012 - This is an analog heated bed for an Ultimaker [or every other 3D printer]. No extra hardware and electronics needed. Heated beds allow the user to print without warping the object. PLA doesn't warp that much, but ABS is known for warping.

Description

One candle [waxiine lichtje] can bring the aluminium 3mm plate to 50 degrees. A double candle can go up to 60 degrees. I haven't tried a tripple candle. Other possibilities are a oil-lamp or a spirit burner[?!] [Maybe with some electronics so you can change the flame power with a servo.]

From idea to working concept: 34 minutes during the Utlimaker Meetup at ProtoSpace, FabLab Utrecht....

For the candle you can cut out a circle in the Z-stage. [I already made the hole in advance when lasercutting the parts...] Make something that hold the candle, I used some metal wire. Use a Aluminium sheet, tape the kapton tape on it. Turn on the candle [wax light]. Place the aluminium sheet on top. Wait till the platform is hot. Start printing.

For a double candle i just made 2 hole in the canlde and put two wicks in one candle. Should works for 3 wicks as well.

Improvements: maybe use a thicker aluminium piece above the flame... maybe use brass... maybe put a thin sheet of glass on the aluminium to get rid of the kapton tape... maybe use some oil between the glass en the hot plate to transfer the heat better...
