? for home 3d printers-- Welding materials

[L Edge]

Looking for opinions from 3 D printers on welding: Refraze it- use the word bond, where I want the head to spray the bond material to the vertical and horizontal pieces and cool and continually go down the length. Understand, its not capable to melt the fixture.

Staite of mind: chunky block is like 1" square and 2" long . Perpendicular sheet is 1/8" thick and 1" long.

I am aware if the same material is used, no problems in general.
What happens if it two different printable materials? (melt)
What if one material is say metal(alum, copper) and the other sheet is ABS or 2 metals welded by abs etc.

Strength test:

Tug it, bend it, torsion, vibrate it, shear it. Piece is going to be expose to airflow. Just an idea.

Is it possible?
Limits?

Thanks

Maybe expoxy injection? Hot glue injection? You would probably have better bonding results. I'd use something like TPU rather than hard plastics. You could get one of those 3d pens and test different bonding materials. Just some random thoughts.

I'm thinking your best bet will be some kind of epoxy like Litterbug is saying or some other kind of adhesive - the melting temperatures and chemistries of metal and plastic parts are so different that I don't think you're going to get a great bond with molten plastic

You might be able to extensively modify a 3D printer to print solder and be able to join steel or copper, but that would be a huge project

Thanks @Litterbug,@telnar1236 , for answering.
I was looking at a concept and just wondered if anybody explored with just taking some stiff thin vertical material and be able to spray both sides of the base with the nozzle to act like a glue or bonding to keep the 2 pieces together without moving. The torque, bending ,twisting forces are very little (don't want to use super glue) for a reason and want to control the corners, pull it apart and redo it in another position.

It would hold some - PLA does stick to metal a bit, just not well. You might be able to use a 3D pen in place of a 3D printer if that's the goal. A normal 3D printer wouldn't be too well suited because the print head isn't really suited to being used as a hand tool
