Best Sunlu resin for your application? Standard resin vs ABS-Like vs PA-Like

This is an ultimate test of Sunlu resin materials, to see which is best from these three materials:
Standard resin, ABS-Like and PA-Like (or Nylon like) resin.
Besides my regular test objects for mechanical testing, I have some new test specimens too. The curing time is also included in this test, I have 2 and 20 minutes cured versions.

I must say this is by far the best test done so far on the resins. Very very methodical and test that actually measure and differentiate on resin from another. I am so glad that I stumbled upon this and learned a lot. Hats off.

[@ClokworkGremlin]

My big takeaway from this comparison is that there's absolutely no point spending the extra money on PA resin when the ABS-like options perform comparably and sometimes better in every single metric, and cost barely more than the standard ones.

[@aberodriguez4149]

As always the information you provide with your experiments are enlightening and provide useful information when needing to create parts that will be exposed to a stressful conditions. Great work thank you.

[@benishehe]

As always, your videos are fantastic. Glad to hear you're coming over to resin printing, I only recently started it as well. Ironically, you had every element of my process in presented: mars 3, elegoo cure and wash combo, and sunlu abs-like.

[@lime3620]

As an engineer, the rigorousness of this experiment gives me goosebumps. Great stuff!

[@scottydogmyers]

These are such great tests! I never thought that cure time would have such a measurable difference. Nice job and extremely informative!

[@jccraftmage2313]

Yeah I actually had never considered that too. I just assumed that once it's cured that's it.

[@SomeoneAbstruse]

Massively interesting how curing time changes mechanical properties. Now curiosity has awoken to how and if translucent filaments are changed. On a side note, it looks like you have proved there is little reason to not print abs-like as standard (given price similarity and mechanical superiority*) *Deals may be struck for wholesale standard resin bringing price down to 10 usd pr kg

[@svetoslavasenov5609]

Thank you! I was wondering which one to choose for my purpuses but now I know. Would be really nice if I could know how they behave after several hours in saltwater.

[@bd700bd]

Thank you a lot

[@gcardinal]

It's excellent that you conducted FDM tests on resin parts, as it allows for easier comparison. I've been using FDM parts in production, primarily ABS, and they've been performing well. I've also dabbled with ABS-like resin in real-world applications, but I'm still uncertain about the effects of long-term UV light exposure and other environmental factors on the part. Furthermore, as resin parts change over time, it's unclear when this transformation ceases and the parts stabilize. For example, I printed a ring box, and after several months in the bathroom, the bottom became approximately 5mm convex from its original flat shape. If I had sufficient time, it would be fascinating to investigate the use of resin parts in functional applications. This research could potentially address questions such as: - What is the recommended aging period for new parts before installation? - How does exposure to UV light impact the parts? - What are the effects of heat and cold exposure? - How do the parts hold up in saltwater environments?

[@jessejuliano8056]

Yes, it would be interesting to see this data. Even some extreme UV chamber exposure would be good, or testing ways to avoid UV damage(additives, paint)

[@artofdon]

ty very informative

[@santiagoblandon3022]

Thanks! very interesting. I've always been curious how resin prints compare to FDM mechanically

[@bahadzhan1111]

Thank you for this video, very informative, I think it will help every maker to understand the possibilities of these resins. And result of impact test from PA like resin was unexpected for me also. I have suggestion cure them also 5min and 10min and test them I think 2min cure is too small amount of time and 20 min is large.

[@ok4377]

Great tests with repeatability across products and scientific execution! Well done. And all that while you live in an apartment, I presume, setting up the test stations ad-hoc every time? Aswesome!

[@peterdocter4659]

For the dropping test maybe look for a clear acrylic or otherwise just a pvc pipe of the lenght you want, put a street-tile under it and drop 1 model, or do multiple pipes, that way, they won't go all over the place and you have the results on the tile, clear to see. (saves your feet from tiny splinters too!) you could do multiple lengths too, if you'd like.

[@MyTechFun]

Good idea, but I don't plan to do this too often. I can easily pick up bigger parts. Smaller I left to robot vacuum cleaner. Only last time I forgot to check inside my shoe, there was one broken map inside :-)

[@anupamdash1102]

i wanted to try using metal inserts on some of my rapid tools but looks like a soldering iron won't cut it :) thanks for the video! underrated in the printing community!

[@dekurvajo]

Aside of fancy mini figures, there are definitely a place for practical printing with sla/dlp. Here is my example. I needed m8 set screws but flexible ones. And i needed 320 pcs. Imagine that job with an FDM. With the dlp i was able to finish it in one day including the extra time of cleaning up the mess. Remember 1 item or 100 items takes the exact same time to print on the DLP. And when it comes to tiny parts, the DLP is the winner

[@krisd9506]

Awesome video! For the cheapest stuff on Amazon, it's pretty strong. Wonder how it stacks up to stuff like Resione K, Resione Anti Impact and Conjure Rigid... Betting they aren't that much better and are much more expensive. Lots of people swear by Siraya Tech BLU, but the Sunlu ABS beats it in most of your tests.

[@donniem7979]

awesome

[@karlosss1868]

Great video as usual. Just a tip... you can measure on the elephant foot side by inserting the calipers a bit more into the hole. The caliper feet are cut away to allow fo this.

[@MyTechFun]

[@luisbustamante5479]

this resin is quite enticing, for that price I'm really considering the switch.

[@WhereNerdyisCool]

There are so many resin printers coming out weekly, it is really hard to keep track. What I dislike is all of those inexpensive machines use fast curing resin which offers no real strength. If you want to print figurines and decorative items in high detail, that's one thing. I would like to use resin prints for high detail pieces my FDM machines can't do. But it needs to be strong. One thing your data showed that I had not seen others cover is the shrinkage. Thank you!

[@dannybuscemi867]

Planning on testing the Standard Plus that just came out?

[@walterrldias]

great video, txs!! would you share the .stl of your test samples, in case we would like to duplicate your results or compare to other resins? or at least the dimensions of your samples, diameter, etc. let us know. thanks

[@fluxcapacitor]

Hi, thanks for this. What would you recommend as a resin type among all these for a phone holder that would stay in a car parked in plain sunlight all year round including of course hot summers? Obviously the temperature would never reach the same as in your oven, but I think it could get as high as 70°C (about 160F). Would PA-like fit the bill?

[@stevesmith-sb2df]

Thanks I don't have resin printer so this was good info. I usually print ABS parts because of the lower creep and higher temperature resistance. I would like to know how to FDM print PETG so the part is as ridgid as PLA. Like 4 walls in PETG has same bending strength as 2 walls PLA. Can you compare ABS and PETG to PLA by increasing wall count and infill.

[@sebastiancamacho8275]

It’s interesting that you do all of these tests and not own your own SLA 3d printer! You should get one! I just got the Halot Lite for ~4500 MXN which is ~267 USD. Good enough size, resolution and technology. I think you should get your own printer so that you can put all your knowledge and tests into practice and also what what you find about the best ways to print! Maybe test if the orientation of the print affects its physical characteristics or other cool stuff 😅 great videos, a little too technical, which is good for us people who like it that way

is there a scratch test, or will there be scratch test included some day? I'd like to know the wear resistance/ease of post processing like sanding(of course since they go against each other, but we require different things sometimes)

Sometimes I do hardness test (shore D) but I didnt with these resins

[@petercallison5765]

Anycubic has an ABS Like Pro which they say is much tougher than the ABS Like plus. they also say it gets tougher over time with exposure to the sun.

[@aiwditbh]

Abs like is quite accurate with dimmensions, while on sunlu states ithas 6-8% shrinkage, have you compensatest for it?

[@hicl5450]

will abs-like resin react with acetone?

[@kishana7756]

Have you done chemical test on these materials? How it reacts with solvent like Acetone or DMF? Which solvent has better solubility of these materials?

I am not familiar with this part, but yes, it would be good to test at least few basic materials.. thx for suggestion.

[@noway8233]

The diference beteewn pla and abs resin is the bottle , one say "Pla-like" and the other say "Abs-like"

[@MyTechFun]

There is a little bit more difference, at least in mechanical specs

[@xeraoh]

Polyamide plastic (PA) is like Nylon, usually the PA-like resin is more flexible than the rigid ABS-Like resins but PA-Like resin is nothing to do with PLA

[@awildtomappeared5925]

it was hard to tell from the video, how matte are they? it looked like the ABS and PA were more shiny, is this the case?
