Tricks for splicing ABS?
Posted: Sun Oct 22, 2017 6:59 pm
I have been splicing PETG short-spools for some time now with good success. I have a little tool I made from a compass (circle-drawing-kind) which holds the ends in good alignment. I close them down onto the tip of my soldering iron and then close the compass down to fuse the ends of the filament together. There's a big mushroom of material that I trim down with some good flush-cutting wire nippers.
I have been trying the same technique with ABS, but the joint doesn't have enough strength for me to feel confident about it making it through the feed - mainly thinking it might fracture as it transitions into the drive gear.
I currently have the soldering iron set to 350C. Haven't tried lower or higher temps yet. Thinking about trying a drop of acetone to perhaps solvent-weld any voids in the joint, although it seems more likely that it would cause the joint to fall apart.
Just wondering of anyone out there has had success splicing short spools of ABS together.
