Awesome. This is such cool stuff! I can't wait for my resin printer to arrive to try some Siraya Blu and Tenacious for flexibility as large threads are mostly what I want to print.

One major thing missed: the orientation of the printed layers matters. You're only testing the layer bond strenghth because everything was printed vertically and you're testing vertically. You need bolts printed along the long axis. This will afford you tests that aren't hampered by layer bond strength which has all kinds of variables like cure time, layer thickness, etc.

I love how fast the Anycubic photon Mono X prints large things, one of the sweet things about an LCD(preferably monochrome) Resin 3D printer is how little if any extra time it takes to print something big and full volume compared to a traditional plastic printer. I've really had a good time printing on the photon mono X, I'd recommend you not use paper towels to clean the vat/fep though, they say it can scratch it. Micro Fiber cloth and maybe kleenex are the way to go because they're much softer and less likely to scratch the fep. Also you can keep the shipping screen protector on to help protect the screen in the event that the feb ruptures.

Great video. Am also glad you show a temperature comparison as I need resin to make parts for my fdm printer that will be close to the nozzle.

Great tests, thank you!

excellent in-depth test!

I understand this is 2 years old. I appreciate the information that was collected in this even though it is small scale testing with application centered around fastening hardware. I wanted to say I believe the difference between the two resin samples was the cure time. If you expose resin to uv light for extended periods of time it can increase the hardness and how brittle it is. It can also cause yellow discoloration, and if left to cure too long, will lead to break down of the hardened resin material itself. I hope that solved the possibly solved difference within your resin samples.

Thank you for your hard work!

Keyboard keycaps have almost no load, I think you are fine with almost any resin

The warm color shift in the second Blu set is due to overcuring, either through overly long layer cure settings or in post during the final cure. Transparent resins continually shift toward yellows the longer they're cured. A "properly" cured piece barely has any signs of this yellowing, and the cool blue tint of resins like Blu helps to offset this effect. I placed "properly" in quotes because like everything, there's nuance here that's worth our consideration. There are benefits to slightly overcuring and undercuring, and carefully controlling these thresholds is rather important to this type of experiment. Regardless, I really enjoyed the video and look forward to your continued endeavors! Cheers.

The reason why the nut won´t fit on the resin prints, is probably due to a lack of cleanup after the print. Uncured resin was probaly still in the thread and got cured (post-cured).

I don't know, not washing the prints before post-cure seems like a pretty huge oversight from a company offering SLA printing services.

Check out the phrozen nylon. That resin seems interesting.

The color difference between the Elegoo and the Photon printer pieces is very interesting. The color hues that occurred after the melt test, are similar to the color in the finished Photon peices. Heat seems to bring out more of a green hue. It suggests that the Photon printers print at a higher temperature to the Elegoo. Not just curing the resin, but kind of cooking it as well.

@ale6242

Thats classic overexposure. Resins tend to yellow when cured for too long. Resulting in the greeny hue

What I expected. It's a big advantage of PETG in mechanical applications that it deforms rather than break suddenly. Resin, if not reinforced with fibre, is brittle. It's just not a good material for mechanical parts, unless of course when combined with fibre. But 3D printers can't do that yet.

This is not a viable comparison. The layers on all prints should be the same direction. You have the Resin layers parallel to the thread, the layers of the PETG are perpendicular to the threads.
