I want to melt a bed of plastic powder so that the powder bed once melted and then cooled forms a solid sheet of plastic.
In order to melt the powder I'm thinking of passing a nichrome (Ni80/Cr20) wire over the bed without the wire touching the bed. With the direction of motion of the wire perpendicular to the length of the wire.
The heat from the wire should radiate from the wire and pass into the plastic powder in order to melt the powder. Is this possible? Is it possible to to melt plastic powders through heat radiation from a nichrome wire.
As an alternative to melt the bed with radiation, one could heat the bed's platform. But I can't do that because the bed's platform is made of plastic and might begin to melt if I heat it. So heating through radiation is the only viable option I've thought of.
Bed dimensions: 30 cm X 15 cm.
I can use a wire of any diameter. Single wire or multiple wire in parallel.
Melting temperature of plastic powder used is 270-300°C.
Any distance between the wire and the powder bed is possible. Close distance between the wire and powder is preferred.
If not nichrome any other material can do the job.
