SLA vs SLS 3D printing (JLC Black Resin vs Nylon) by JLC3DP

[@VRPA3D]

I like results after each testing

[@MyTechFun]

Vote noted. For me, it would be better, since I can see from stats, many viewers just jump to result part, skipping most of the video. But I don't care about that, I will do the version which gets the most votes.

[@survival_man7746]

I like the result after each test too so I can look at the test that I prefer and quickly go look back when I need a specific number​@@MyTechFun

[@NuggetsInclusive]

@@MyTechFun as someone who tends to skip. i dont mind you keep it after each part. Maybe you could chage it from just being a summery at the end to being like a comparison. say vs. the top 5 materials or top 10 ever tested in this category :) woulld be intresting as you test things to see new materials take thoese top places! either way as always Great Content! keep it up :)

[@DrZylvon]

@@MyTechFun I often jumped to the results then reverted back to specific sections when I'm puzzled about your conclusions etc. Or when I have more time, I skip around, looking for on screen results. Perhaps I think results after each test is better and aht the end of the video, perhaps a slideshow (silent) with the results, paginated?

[@SeanCMonahan]

I prefer how you presented the results in this video! Having the results right after each test made it easier to understand going along.

[@DynamicDesign144]

One advantage that Nylon has over most resins (I don't know about this particular one), is that you can use threaded inserts in it. I have yet to find a resin that will accept heat-installed inserts. I like the results after each test, makes it a lot easier to keep track of the results while watching the video. Maybe also post all results at the end briefly for those looking this video up as a reference as one commenter mentioned.

[@MyTechFun]

Oh, yes, great comment (threaded inserts)

[@nathanteig7108]

Some resins can be tapped

[@warmesuppe]

I think its because most resins become duro plastics so they don't like to melt. Gluing them in or threading them in with glue should be the preferred Solution.

[@DynamicDesign144]

@@nathanteig7108 Yes, we used to 3D print the threads or tap them when I worked at a place with a resin printer. That particular resin was quite brittle though, so we definitely had issues with parts cracking and breaking from the stress concentrations at the threads. Some other materials were better in that regard but had other drawbacks. Overall Nylon seems to be more durable for functional parts used in assembly fixtures, which is my main experience. The resin parts were great for prototyping though as the dimensions were always spot on as long as they didn't warp during post-processing

[@erikhoffmann1252]

Still the best 3D printing channel on KZbin

[@jomix282]

I agreed, the result right after give us context and remind what the subject is, Excellent video 🇨🇦 Quebec!

[@survival_man7746]

I like to see a graphic after each test and a summary at the end

[@romainmuller-rs5yi]

Grear video, as Always ! I think I prefer this type of presentation. You can immediataly see the conclusion, instead of waiting the end, were the viewer probably already forgot the results.

[@nicdinecola]

I prefer the result after testing. It was really interesting to see the SLA and SLS materials. I havent seen much SLS info, so this gives me a better feel for it

[@JelleKalf]

@myTechFun put me up for inline results after each test as well. I liked it.

[@ScytheNoire]

Like the results after each test.

[@jwiz1911]

I prefer results at the end of the video. Interesting materials...I don't have an immediate need for something like this but it's impressive to see how inexpensive they can be produced if necessary.

[@JelleKalf]

JLC3DP is a nice company. Used them for pcb prints as well. Never knew they also did certain nylon sls prints. interesting for some functional parts which are harder to print on an FDM printer.

[@MyTechFun]

In most cases I can do all prints myself. But I already used their metal 3DP services, when I needed some big strength. And they have great prices (compared to similar company I presented here)

[@blackpete]

Any experience with qc and returns?

[@JelleKalf]

@@blackpete On the PCB's I've never had defects. Good stuff fast delivery.

[@alexvmw]

Я всегда смотрю на таблицу в конце видео. Очень ценю ваш канал за это. Но и результаты после каждого теста тоже не лишние.

[@klave8511]

I prefer the summary at the end, easier to compare the properties that way and easy to go back and forth to review.

[@Ar-Vee-Cee]

I love your videos, It would be great to hear your views and see some testing on Bambus new PPS-CF material. Keep up the great work

[@harkrits.nagpal6505]

I recommend you make the tensile strength objects all one single object held together by those little cutaway pegs you use! I remember in an earlier video that you had issues when you had gotten all parts printed in the same orientation by the technician. I haven't reached the testing part of the video, at 3:13 but this way you can be SURE at least 2 parts are printed horizontally and 2 vertically! I am talking about having one single object with two test objects in horizontal direction and two in vertical. So that printing orientation not only becomes obvious to the technician, but also even if they message up somehow, the parts are still at 90deg. I know SLS might not have recommended print orientation but you can even have 6 objects in 1 maybe

[@henninghoefer]

I like the analysis after every test

[@riba2233]

very interesting, that resins is pretty strong. expected much more from nylon, should be around 50 in both directions. So it's only worth it for some very complicated parts that would require many supports imho

[@Boz1211111]

Analyzing results immediately is easier to follow, and i assume it might improve your retention rate so keep it!

[@perryr4796]

I like results after each test better as well

[@chris993361]

I too like the results after each test

[@koralitto]

Personally I prefer results at the end. When comparing materials from two videos, or when you've watched video some time ago and just want to refresh values, it's a LOT easier having, let's say, condensed results in a one block of a video, rather than trying to pinpoint each result.

[@Artem-ds6yx]

Same here, however I understand that viewer retention is a thing and KZbin really cares about it.

[@PauliJuppi]

I like the results right after👍

[@theoverlord3839]

I also really like results after each test

[@supercurioTube]

I like both the results in the middle and at the end 😌but I suppose that results after each test might increase the time watched in your videos, instead of many skipping until the conclusion? Another suggestion is that although the whole table is reserved to Patreon supporters, some more context would still be useful when presenting the results, like: typical 3D printed PLA, Nylon, PETG+CF and a a couple relevant. I watch almost all the videos so the database is in my memory, but I'd still like appreciate a reminder 😆

[@SQalli]

I prefer the results after each test.

[@PeterLukac-r9n]

Hi Igor, in one of your videos, you showed storing filament in silver vacuum bags, but I can’t find the video now. I believe it should be from one of your 2024 videos, as earlier you were using plastic storage bags. Would you be able to direct me to that video ? Were those bags Mylar foil? I’m looking for the best way to store filaments airtight. Some people suggest that sealed plastic containers work well, but I think vacuum storage bags might be much better.

[@freedomofmotion]

I think both a summary and straight after test would be ideal.

[@Flaakk]

Do you have more information on the resin? I'd be interested in knowing exactly what polymer it is so I can use it in my SLA printer.

[@PatrykMajewski-ui5nj]

this video is better btw great work

[@Daan87423]

I see IGUS filament in the background, interesting!

[@MyTechFun]

IGUS, AddNorth, 3DO, Sunlu, Phaetus, Siraya filaments, BQ Airless Basketball filament, ...

[@Daan87423]

@@MyTechFun Wow, lots of work to do. Any chance it's the Phaetus PET-GF?

[@santiagoblandon3022]

I think after each testing. It makes the video more engaging. When the results are at the end, i jump right to the end i must admit 😓

[@Igor.L.23]

I must say I like to skip to results when browsing all your past videos. Suggestion: add a comparison at the end with a few similar materials so we can have more context, say the current top 3 from your table in same category, and maybe add a wear-and-tear if you can for these more functional materials (not for PLA for example)

[@ROBOROBOROBOROBO]

Hi Igor, will you continue the food safe 3d print series? Vapour smoothed SLS might be a new candidate. Its so weird after all these years, there is still not a real solution on the market, SLS PA12 and vapour smoothing with a machine like AMT Postpro claims food safety and processes are certified, one can even order it from Xometry with part compliance certifications but is it really food safe? :D Another option might be to SLA print a mold and using a desktop injection molder inject your cup shape however issue here I think more than the bacterial test might be the chemical migration tests might fail as SLA is toxic

[@phizc]

The results after each test flows better and has better context, but all the results at the end is better for overall comparison of the materials. E.g. if I need a material to be strong in tensile, and good at elevated temperatures. With the results after each test I would have to keep track, not just quickly get all the results in the same place. Not a problem with 2 materials like this, but some videos have many more materials. A compromise could be to present the results after each test, and show the spreadsheet and graphs for a couple of seconds at the end of the video. You wouldn't have to explain the results again.

[@SeanCMonahan]

What sort of things does JLC's manual order review process look for and catch? Printing orientation things? Unsupported parts? Overhangs? Long bridges? Do you have the ability to specify slicing parameters, like layer height? (I'm watching on my phone's mobile data, so I can't really make out the details on the quick ordering process you walk through.)

[@jimjohnson3410]

The new record shipping time had me cracking up. I have had great luck with their products but shipping takes a bit when I am being cheap.

[@The_Privateer]

Summary of all results at the end.

[@accumall3027]

why is the SLS nylon so less strong than SLA resin?? what is the strongest SLS material now?

[@PaoloBernardoni]

I prefer the results after each test. Quite disappointed by the SLS nylon, it performed worse than most nylons for FDM printing, the only advantage i see is the possibility to print more complex structures.

[@garagecedric]

We order many prints at work, fdm isnt that useful to use for parts that arent designed to be printed. Sls or mjf have much better surface finish on faces that need support structure for example. The designers dont have to think about the printability or support structure minimising.
