Okay, so I’ve been messing around with this “bdg3 medium toughness” thing, and let me tell you, it’s been a journey. I wanted to toughen up some 3D prints, make them less brittle, you know? I saw some stuff online about this bdg3 stuff and figured, why not?
Getting Started
First, I got my hands on some of the bdg3 resin. It’s pretty easy to find online, I just did some searching. I also made sure I had my regular resin, the one I usually print with. Safety first, kids! So, I put on my gloves and safety glasses – don’t want this stuff getting on your skin or in your eyes.
Mixing it Up
Now, the tricky part: the mixing ratio. I decided to start with a small test batch. I’d seen folks online recommend different ratios, some saying 10%, others going up to 20% bdg3. I went with a 10% mix to start – 10 parts regular resin, 1 part bdg3. I just used some small measuring cups to pour them out and then mixed them together really, really well in a separate container. You gotta make sure it’s totally blended, no streaks or anything.
Printing Time
With the resin all mixed, I loaded it into my 3D printer, just like I normally would. I picked a simple test print – a little calibration cube – to see how it would turn out. I hit “print” and watched it go. Nothing fancy here, just a standard print setting.
The Results (So Far)
Once it was done, I cleaned the print like usual, with the isopropyl alcohol bath and a good rinse. Then, the curing. I popped it into my UV curing station for the recommended time. And… it seemed pretty good! Definitely felt a bit tougher than my usual prints. Not like, super strong, but noticeably less brittle. I could bend it a little without it snapping immediately, which was a win.
Next Steps
- I’m definitely going to try a higher percentage of bdg3 next time, maybe 15% or even 20%, to see if it makes a bigger difference.
- I am going to test and print other objects with different sizes.
- I also want to print some more complex shapes to see how the toughness holds up with thinner walls and more intricate details.
It’s still a work in progress, but I’m feeling pretty good about this bdg3 stuff. It seems like a simple way to add some extra durability to my 3D prints. I have a good feeling with this.
