Fixing stress delamination

[Seajay]

Hey yall, I have a 3D printed magwell for my Phenom and it looks like I have delamination on a single layer on both sides. It is quite small and my guess it is being caused by the tension from the mounting bolt. Unfortunately it does need to be somewhat tight to function well, so I'm going to assume I caused it.

So, what can I do to repair these layers? I'm more worried about long term use from long term tension. I will be trying to use thin spacers to alleviate the stresses by reducing gaps, but I'd like to fill or seal these two.

How do I do that? This should be ABS material.

It can be rough to get something that looks good and hold up ...

Supper glue (cyanoacrylate) or epoxy is a good way to hold things together, but it can be difficult to make it look good.
I've had very limited success with soldering ...

For high use mechanical parts, 3D print (plastic) remain short use item ... Maybe one day we'll have a better technology, but we're not here yet with FBM ...

Let us know what you end up doing and how it turns out.

If it is ABS, you can try to use acetone to chemically melt/fuse the pastic. Though, be careful if you try that, It can cause warpage if overexposed. But like Xemon said, It's a plasic, short-term use item after all.

If you don't care about the aesthetic, you could goober on some epoxy with some glass fibers.

Another thing I've done at times is do plastic "welding" - essentially use a soldering iron and some extra plastic and kinda TIG weld pieces together. You want to melt some of the parent plastic on both sides of the crack, and then melt some additional plastic into the gap. Looks ugly, but holds up for a little while.

If you want to pay for new glue, loctite plastic glue does work on most filaments. It will test the next layer.

I'd also look at Plastruct Plastiweld. It's super thing and will get into the tiny cracks that are forming. It's super caustic crap so wear you some PPE.

Thanks all for the suggestions. I think I'm going to shim it up and then while it is under tension again try some super glue with a little heat.

Sadly it is new, not even seen the field yet. There is a ton of material around it so I'm hoping this is the extent and isolated.

This is why I only use PLA+ esun , absolute layer adhesion at 230c.

I try printing PETG, ABS, I can snip a solid block in half with scissors it's so bad for me, I don't know how you guys manage.

I should probably invest in a printer...

So the delamination hasn't progressed at all. I shimmed the meeting points and increase surface area to spread the tension out, so less flex more grip. I used some gel super glue along the two points and it looks like it closed up.

I roughly used it, flipped a magazine about 30 times rapidly, and it looks solid. Still feeds and shoots well, so I'm calling this good.

If you are going to Fulda and see me I'm happy to let ya have a go.
