If you’ve ever tried to glue two 3D printed parts together, you know the struggle. You apply the glue, hold the pieces in place for what feels like an eternity, and then watch in frustration as they slowly slide apart or take forever to cure. I’ve been there more times than I’d like to admit.
That all changed when I discovered the Magic Chems CA Glue with Activator Kit.
The Game-Changer: Instant Bonding
Here’s what blew my mind: you apply the CA glue to one part, mist the activator on the other, press them together, and boom—bonded in seconds. Not minutes. Seconds.
I recently printed a large project that came in multiple segments. Normally, this would mean an afternoon of holding pieces together and hoping for the best. With the Magic Chems activator spray, I assembled the entire thing in under 20 minutes with rock-solid joints.
What’s in the Kit?
The Magic Chems CA Glue Kit comes with everything you need:
- Medium CA Super Glue – Perfect viscosity for 3D prints. It flows into gaps without being too runny.
- Activator Spray (16.9 fl.oz) – This is the secret sauce. A generous bottle that lasts through dozens of projects.
- Extra Empty Bottles, Nozzles, and Pin – Because we all know glue nozzles clog. These extras are a thoughtful touch.
Why This Works So Well for 3D Prints
3D printed parts—especially PLA and PETG—can be tricky to bond. The layer lines create uneven surfaces, and many glues either don’t adhere well or take too long to set, causing parts to shift.
The Magic Chems medium CA glue has the right consistency to seep into those layer lines while the activator ensures an instant cure. No clamping. No waiting. No repositioning because your parts drifted while drying.
My Workflow
Here’s the simple process I now use for every multi-part print:
- Dry fit your parts to make sure everything lines up
- Apply a thin line of CA glue to one surface
- Mist the activator lightly on the mating surface
- Press together and hold for 3-5 seconds
- Done. Seriously, that’s it.
The bond is strong enough that the printed plastic will break before the glue joint does. I’ve tested this. Multiple times. (RIP, test cubes.)
Beyond 3D Printing
While I primarily use this for my prints, the Magic Chems kit has become my go-to for quick repairs around the house. Broken ceramic mug handle? Fixed. Loose wooden drawer pull? Secured. That one pair of glasses that keeps losing a nose pad? Finally sorted.
It works on wood, metal, glass, ceramics, leather, rubber, and most plastics—basically everything except polyethylene and polypropylene (which nothing really bonds to anyway).
The Bottom Line
If you’re doing any amount of 3D printing that involves multi-part assemblies, do yourself a favor and grab the Magic Chems CA Glue with Activator Kit. The time you’ll save and the frustration you’ll avoid is worth every penny.
Your future self—the one who isn’t holding two plastic parts together for ten minutes while questioning their life choices—will thank you.
