Water Cooled RepRap > > >

Adrian Bowyer, inventor of the world’s most popular home 3DPrinter genus, the RepRap, has been experimenting with a water-cooled print head.

Whilst the fan-cooled heads are a highly successful design, having a very short melt zone and high-power to respond to changes in load, the fan is often deemed relatively bulky.

The application of water cooling, which has emerged as a subtle but growing trend in the home computing world, has an outcome much lighter and more compact.

Best of all the cooling is more efficient.

A brass block that replaces the normal aluminium cooling block that attaches to the fan.  The brass has water channels drilled in it, and some soft silicone tubing connecting it to a small 12V gear pump.  The inflow and outflow temperatures are only a fraction of a degree different, meaning that multiple heads could be chained in series and all cooled by the same flow.

Here is a video from the inventor’s labs to whet your intrigue…
