        <title>Nichrome Wire</title>
        <description> What gauge Nichrome wire is best for this application?  The build wiki state 7 ohms of wire but no gauge.

Thanks!</description>

            <description><![CDATA[ Just thought i would mention, that you dont realy need nichrome with insulation, i bought mine off ebay! one layer of Kapton tape on the brass, wire rapped around thread, another layer of Kapton,and then wrap wire back over again, I currently have 150 ish print hours on this nozzle! and its hasnt missed a beat.]]></description>

            <description><![CDATA[ Looks like Nichrome 60 has a slightly higher resistance than Nichrome 80 of the same diameter.  For example, 30-gage (0.010) wire is 6.75 ohms per foot in 60 and 6.5 ohms per foot in 80.<br />
<br />
Both melt way above the safe temperature for Kapton so either should work.]]></description>

<br />
They should be similiar in performance. The only difference is the increase in length due to a smaller percentage of Nichrome.]]></description>

            <description><![CDATA[ I wouldn't advise that: the nichrome wire has to heat up to a temperature higher than the extrusion temperature, due to the thermal resistance of the barrel. That means that, for an extrusion temperature of 220C, you may have to heat the nichrome wire up to 270C, say. So you may degrade the teflon, even though the extruder works at a reasonable temperature.<br />
The exact values will depend on your machine and are not straightforward to obtain. There may be some cases where this would not be an issue, but I would be careful with teflon, if I were you. It can be pretty toxic when it degrades.]]></description>

            <description><![CDATA[ I'd also like to know if this alternative insulation works. My nichrome's insulation has come off and it would take too long to order a new one all the way to Japan... <br />
<br />
At the wiki it says "<i>...uninsulated wire should work as long as extra measures are taken to insulate the wires from each other. Kapton Tape or alternatively Teflon Tape is utilized for extra insulation.</i>" Has anyone tried using Kapton around the whole wire?<br />
<br />

            <description><![CDATA[ I don't think the length is particularly critical, although longer lengths allow you to spread the heat more evenly. The resistance of the length you choose however is directly related to the current that the wire consumes, and hence its heating power. A thinner gauge at a longer length simply spreads the same amount of heat over a larger area, so we specify resistance rather than gauge and length]]></description>

            <description><![CDATA[ Depends on how big your extruder barrel.  We used to specify #31 AWG.  In recent times, however, we've been looking at much longer lengths of glass insulated nichrome from Pelican Wire in heavier gauges like #27-28.  The longer lengths lower the temperature on the surface of the nichrome and keep the insulation from perishing.  I put together a Rapman 3 extruder head with #28 {7 ohms} and Kapton tape with JB-Weld securing the thermistor.  It's been running without complaint for several weeks now.  :-)]]></description>
