Printing using paraffin as a support material?

Has anyone explored the use of paraffin as a support material?

I see use of waxes in 3D printing for mold-making, but not as support material. Seems to me that simple paraffin might serve as a recyclable support material, removed with a bit of heat. Also paraffin-soaked FDM prints have a better chance of proving air and/or water tight. (Not so good if you want to paint your prints.)

In mind, this is a heated upper chamber, forcing wax through a Teflon tube. (Low enough friction when solid?) Then heated again at the nozzle.

... plastic won't stick to paraffin ...

With polycaprolactone (polymorph) could work.

Fair enough, some adhesion is probably useful. On the other hand, when printing overhangs and bridging, we are in effect printing on air. Pretty sure even non-adhering wax offers better support than air.

As the melting point of polycaprolactone is listed as 60C, and bed temperatures can be that or higher, looks like we what something with a higher melting point.

... there are some low-temp-melting metal alloys -- "Roses metal" is less toxic than "Fields-" (Lead replacing Cadmium) and melts around 100 degC ... so could work for higher temp. melting materials ...

When the hot filament hits the wax, it will melt the wax. It's unlikely the wax will support much in its melted state.
