Five 3D Printing Processes Put To The Test

- Which 3D Printing Process Should You be Using? That's the question I want to answer in todays video where I compare SLA, FDM, MJF, SLS and SLM processes with one material from each in a range of different tests to see which comes out on top.

they didn't fail the continuity test, they passed the insulator test
Haha, very true.
I run a mostly B2B SLS printing service bureau, so I'm well aware that SLS in general and for small parts particularly is not as expensive as people think it is, if you don't go into the realm of filled or engineering materials. we print a lot of spare and custom parts for industrial applications in Nylon PA12 and that's quite affordable, it all depends on the sintered volume and on how the parts can be nested in the build chamber.
A service as big as I think JLCPCB is should have enough orders on hand to be able to fit loads of parts in the build volume and cut the costs down a lot
Nice test!!
I just happen to use these printing services for some 3D printer cooling fan duct, hotend mount & mouse mod parts in SLS/MJF.
They are cool and convenient (I live near them and shipping are cheap)
I'm happy to see how good they're from your test rather than reading datasheets 😀😀
FDM (Fused Deposition Modeling) is now known as FFF (Fused Filament Fabrication) for anyone confused about seeing that terminology in the wild.
Great video! Dumb me had a hard time with the graph with load on X and deflection on Y haha
I think the flower test pieces might not tell you anything for prints from JLC. JLCPCB orients prints arbitrarily, and as the material doesn't shrink across layers makes these samples incomparable. All of them would need to be printed in the same orientation.
Great video, it would be nice to see the graphs again but with cost put into them. ie: strength vs cost
So that's what that contraption you built was for
if you need anything to get printed in metal in the future I have a modified prusa mini heatsink I'm happy to send you :P
I think I saw you share it printed in PETG? What was the purpose, was it Revo?
@@Vector3DP yeah retains the original prusa mini shape and size but revo compatible. the micro is nice, but I'm kinda surprised prusa/e3d didn't already do this
Although I don't doubt your individual results for accuracy/skew, I would like to note that your samples definitely weren't representative of the different processes, and I know for a fact that whoever was running that MJF printer wasn't doing their job. Size of tolerance that you can't fix by knowing what you are doing is definitely SLA < MJF < SLS < SLM < FDM.
Haha wow! How can I get that metal x-carriage? 😁
I thought you might ask. I gotta keep this for a while as might be using it for other testing. Can order from JLCPCB though.
@@Vector3DP of course! I think I might invest in an aluminum one instead :)
Remember to adjust the holes where the threaded insert go 👌
I realise this wasn't the point, but wouldn't heat-set threaded inserts into stainless steel be completely pointless, even if you could somehow get them inserted? 😆
Isn't brass softer than stainless steel, thus adding brass threaded inserts into stainless steel would just make the threads _weaker?_ 😸
Yep. On the carriage I've changed the hole size so it can be tapped for m3 thread 😊
Uhh bet your test leads are 0.03 Ohm at least. Since you're not using a 4-wire measurement.
Humm, ye slight oversight on my part there maybe. Well the point was its conductive.
hydraulic press crush the metal insert
or shrink metal insert push expand cooling
dont use plastic processes for metal mechanics
