Hi,
Is there any other alternative method for melting thin layer of metal powder without using laser.
Thanks
For 3D-printing, there is no alternative to laser. For coarse welding work there are alternative: arc welding with powder (PTA).
Thanks Vadim
Actually I interested to melt metal not in just one spot as laser does. I need a technique that allows me, for example, melt a layer on A4. An area not a spot.
For melting of metal powder on a surface area, there are the different methods. For example, induction heating or heating with burners. Even heating with concentrated solar beam is possible.
Try electric current (resistance heating) if substrate dimensions allow.
First of all: what is a thin layer?
Generally plasma arc welding with powder can be used for coating of large areas quite efficiently.
Electron beam is another method. Due to very fast beam deflection, larger areas can be treated quasi simultanously.
Are you melting onto an existing dense substrate or do you want to melt a thin bed of powder or even a single layer of powder granules/grains? What metal is it (i.e. what temperature do you have to reach)?
What you are using will influence your practical choice of heating method.
Additive manufacturing using electron beam heating is a commercially available alternative to laser melting, by the way.
Thanks Steven,
Actually, I want to figure out a method that at least leads to sintering of layer of metal powder on similar solid material up to certain thickness. For instance, I need to compress it 10 micro meter and layer thickness in variable and most of place is 10 micro meter.
Sintering is not enough for what you intend with the A4 layer? By the way, A4 the tool steel?
