The MK3 of SLA resin printers? Prusa SL1 and CW1 review!
Вставка
- Опубліковано 23 січ 2020
- Prusa are in on the high-detail resin printing game - but the first resin printer is a bit of an oddball for them, launching as a premium machine into a market that's already dominated by simple import machines like the Elegoo Mars or the Longer 3D or Anycubic machines. So do Prusa manage to add enough value to their SL1 to warrant a 6x price premium? In any case, I wouldn't want to use a resin printing system without a cleaning / curing station like the CW1 again, the real winner of this review!

Nice, the printer also comes with an included teleprompter.
Primož Brglez loll
That was actually my first thought 40 seconds in...paused vid...scrolled to comments...
Primož Brglez had it covered!
@@dimitri877 Same! xD
@@dimitri877 exactly what I did

Trying to figure out how you actually read the teleprompter on that PRUSA...amazing vision you have...
Always wear appropriate safety equipment. Do not eat or drink when working with UV resins. Never intentionally ingest resins. If accidentally or intentionally ingested, call a physician immediately and show packaging or label.
The intro was still amazing 😂

If accidentally or intentionally ingested expose to direct sunlight and you'll be cured.

"Premium price point prusa proposes per printer"
Now say that one quickly 5 times in a row :P (17:25 ish)
perhaps...
Alliteration
Came here for this comment. What a great piece of alliteration!
I wonder how many takes that one took...
You just made me very happy showing my Mini Octopus on your video. Thanks!!
Great in depth review Tom. The new studio looks great and all your work on the acoustic panels paid off, the audio was perfect.
I thought that was your fridge at first lol
I admire your honest reviews Tom, given your relationship with Joseph Prusa. You really called out it's both pros and cons without any bias.
"Premium PricePoint Prusa Proposes Per Printer". Nice!
Great review. It's hard to see past those lovely prints, but you did a great job of showing all the pros/cons. I know full well that I'll get into a mess with resin, so I'm avoiding for now though.
congrats on your new studio!
Just bought a Photon S for 1/3 price of Prusa, and after this I know I made the right choice in terms of value for money.
I really doubt the quality is any different than the Photon. Elgoo Mars isn't exactly the best to use as a comparison, but the Photon is definitely better.
@@TechnologistAtWork He wasn't going for price point when comparing with the Mars, he was going for printing capacity and plate size. Of course over a grand compared to 250 bucks isn't comparable, but honestly, the Mars is a much better deal.
@@TechnologistAtWork the do exactly the same thing, why is the photon any better?
Thanks for the review, good to see your results and hear your opinions.
I wonder about the hollow mode you'd like though: I think it's not as simple as it first might seem because of (1) the need for internal supports and (2) the fact that the interior would need to drain. That second bit might mean you'd always have some uncured resin seeping out.
OT: Cool, your new studio with the the accustic panels are in use! 👍
This is a really helpful review. It's clear that Prusa SLA printers are hot on the tail of other big names. The LCD is the exact same LCD used in the elagoo/Anycubic, etc. And the tilting vat is reminiscent of the Formlabs Form 1. Additionally the screen and bezel are an exact copy of the Form series printers. Even the wash cure station looks like an exact visual copy of the form wash cure station. The shape, the way the hinge opens, the magnetic mixing impellor. Very interesting.
Absolutely first-class review. Highly appreciated.
Excellent video and tour of the SL1 printer, thank you!
Tom : I don't think we will see carbon-copied SL1 machine any time soon.
Fysetc : Hold my beer.
Nice comprehensive review Tom 👍 - thanks
Thomas, i really like you studio...its so clean and minimal looking...i never realized it before
I bought them both two months ago and did a review too!
Wow, the reflection of your teleprompt in the first minute there: I never realized you used one. How cool! I want to try this. :)
Ha I had no idea you were reading off a prompter in your videos. You do it pretty naturally, and I wouldnt have known but I would see the reflection in the SL1.
Another thing I wanted to mention is that I also mostly use Water Washable Resin now. It has a little less odor than regular resin. Still not good for you but less odor is always better.🥴 You also save on not having to use IPA as much. I still use IPA to clean my build platform and tools and any time I use other regular resin for some reason. In any case it is one less hassle to deal with. 😉
As soon as you said its 6.5x more expensive I bounced. They've earned a price premium in i3 style FDM because they have a quality control and solid design. But resin printing is much more solid.The tilting and resin level sensing is cool. I look forward to the open source replicas :)
Looking forward to a review of the SL1S. Curious to see how the tech has advanced.
nice video, thanks!, Do you have any thoughts about the Phrozen Resin Printers? I'm thinking on buying the Phrozen transform.
Thank you for the review and being thorough as always, Tom. Much appreciated!
As a designer and a maker who has been using various 3dprinters for over 10 years, I find that "reliable" features from companies like Prusa or Formlab do worth the higher price compare to the chinese cheap printer that works great only probably the first few month and end up not able to find the supports the next year...
Seems like they're positioning this as more of formlabs competitor rather than a elegoo competitor. Particularly with the software, looks like they benchmarked it from Formlabs (which doesn't have a hollow feature either)
Glad they at least include resin volume sensing, I couldn't believe the formlabs didn't have any way of determining if there would be enough resin to finish a print.
i love how we can see the telepromter in the reflection of the printer
seeing the teleprompter text mirroring in the printer was kind of a nice visual effect
Liking the new place, I think it's got more natural light.
Standout aspects of the SL1 for me:
- Heavy! This little box is stuffed full of gravity. Way overbuilt, but easy on the eyes.
- Most reliable 3D printing experience I've had with any type (including several fully updated Prusa FDM machines). I've yet to have a print fail, even though I've printed some really iffy models with minimal support.
- Resin prints look fantasic, but for mechanical parts it's harder to get a precise fit than with FDM (still figuring out the dimension changes and warping that different resins exhibit to varying degrees)
The new SL1S is a big improvement over the standard SL1. It's much faster (up to 3x) and even has better print quality despite basically having the same resolution. I think Prusa addressed a lot of issues with the SL1, CW1 and software. They now have a high quality and reliable setup. It may be expensive, but it's still much cheaper than a Form 3 and in a lot of ways it's better. Sure there are much cheaper MSLA 3D printers out there with 4k screens and other attractive claims, but Prusa gives you MUCH better build quality and great customer support, not to mention the community they have fostered is amazing.
Thanks for your honest review. I will wait 2nd Gen.
Being someone that owns a Formlabs Printer (I also bought plenty of Prusa Products, not bias), Wash Station, and Curing Station. I still would rather stick with FromLabs even if it is more expensive. You dont have to unload/load IPA, the part is lowered into the IPA automatically, and raised to be able to drip dry some. If I do have to change out the IPA I can either use the included hand pump, or lift the whole bucket out to pour it. Also came with a hydrometer (maybe this one came with one as well idk) to test the IPA, to make sure it is still cleaning.
For me the only downside is it's a slower machine being that is SLA. But the post processing seems to be a bit more enjoyable then this one.
Hi, just wondering does your organic vapour cartridge do a good job at reducing the smell and if so where can u get them? Thanks
Print hollowing in Prusa Slicer IS coming soon. It’s in the works and if it doesn’t make it into the release that’s currently in alpha, it will be in the following release.
new update to the prusa slicer; hollow and drainage holes. Just got updated very recently
How does the final resin compare to filament materials like pla, petg, and abs? Stronger, more flexible, wear resistance, etc.?
is that a torque screwdriver you used to open the "carbon filter" area, if so do you mind to link it or recommend one, thanks great channel congrats on the new space :)
I liked trying to read your script in the reflection
Apparently, you can use Simple Green Cleaner instead, cheaper replacement of ISO Alcohol. Also thought to be better. Just a thought.
Nice to see you write down what you are going to say before you make the video.
Great video!!!! But would you recommend this printer for printing fine detailed jewelry so i can cast the prints later ? I'm looking for a affordable 3D printer for my small shop, so a small building plate is fine for me.
Steve Mouton I have to say as a consumer and your build case, a SLA printer seems like a perfect fit. You are not going to get the fine detail on a FDM printer the way you would want it
I definitely want one, but I want a bigger printing area.
I bet they come out with an SL2 in a year or two, and it will have a bigger LCD panel, better resolution, etc.
Where it at though. 😂
I've heard you can actually put the IPA in the sun inside of a clear container to make the unhardened resin harden and sink to the bottom. This wat you can reuse the IPA and just filter out the plastic pieces with a coffee filter
A question for people with MSLA LCD based printers: has any of you repaired the LCD by replacing the polarizer film, or does the screen degrade inside the LCD itself?
I'm wondering about making one for myself as well (after an FDM that is) and not too keen on replacing LCDs every dunno how long, but also would prefer that instead of the galvanometer mirrors so it's faster.
If it's repairable by replacing the polarizers on the screen then it's a lot more appealing.
the otehr problem with the screen failing after 501 hours is- what exactly can we expect for parts longevity? is the lcd screen going to be available in two years? (I ask something like this specifically because i use a Huion tablet display and they have to revise their product lineup every 18 months or so because of LCD availability)
What is the dimensional accuracy of the parts?
Thank you, I order the combo.
Would you still recommend this resin printer? Currently have a MK3s but I’m wanting to get into resin
I was trying to read along with you. I also see that you found a spot for your one camouflaged sound dampener.
My curing station is a nail UV light that has a servo that hits the "on" button every 29990 milliseconds.
You must use a big screen for your teleprompter. As someone who started using teleprompters it is not easy to look Natural while reading a teleprompter. Good job!
I see the sl1 competing with the prosumer market of SLA. From that perspective I would definitely be wanting the SL1 because of the reliability and support over the cheap ones.
Or you can have several cheap ones and replace them if they break and you're not getting support. I understand the support argument, if the price wasn't so *ridiculously* high.
I guess its logical for Prusa to expand into the resin printing. Prusa is building up a business, brand name and diversifying a bit by offering the SL1. It will be interesting to see what they do going forward and how it turns out.
I'm still uncertain if the giant price difference is worth it. Extra features is handy, but what about print quality over say the Phrozen Sonic Mini that uses a LCD screen that lasts much longer.
Do any of the Resin printers support remote control with something like Octoprint?
With resin printers I feel we're getting into the territory of "diminished returns" in terms of cost/benefit
Can you use Methylated Spirits instead of IPA? IPA is very expensive and difficult to get in large quantities where I live.
Hi Tom please can you review the photocentric magna and it’s post processing. They also have a solution better than ipa that doesn’t leave the white marks and is reusable. Great review btw. Would also love to see a “resinween” series.
Paul Robertson He rarely reviews $20k machines.
Is that your teleprompter we're seeing the reflection of?
It is :)
Jesus. That opening. I cringed so hard. I knew it was orange juice but still.
Love the intro!
It's funny to see his teleprompter in the reflection of the sl1 printer
I'd like to see this compared to the EPAX which also has really nice build quality.
I'd like to add another P - Peopoly. Just to compensate an alternative for PPPPPPP. As for an B, releasing the printer as Open Source is a very bold statement. T for Thumbs up. While we are at T - Tom, thanks for a honest and compact review!
Get one Anycubic wash and cure station, only use it for washing. also has a seal on its IPA container.
should be easy to print a mounting adapter.
LOL, just noticed the Tela Prompter reflecting off the printer cover. Didn't see it the first time I watched it.
Those vats need a handle, I wonder if you can distill the ipa and clean it or filter it?
17:23 A lot of "Ps" in that phrase! haha
Indeed, I thought he was about to rap.
Good video! Is there any experience with good resin to print functional parts like tools? All the resins i have used so far are brittle and breaking easily when impacted by mechanical force.
All About 3D Blog a lot of people on the photo facebook add in about 20% of a flexible resin to help prevent parts from being so brittle.
Thanks for the info, need to study on this. Would be good if manufacturer would also provide ready made solutions for this.
I was surprised to see the build volume is so small :( I love Prusa, but this is way expensive compared to other resin printers. I have a mk3, but have been looking at resin printers lately. I'm really leaning towards the Elegoo printers.
It looks like a really solid built printer bit the price is almost double what I originally expected 😬 especially considering that the print volume is the same as all the other low cost printers on the market. It this was even slightly larger volume the price tag would be easier to swallow. this is closer to the price range of the Phrozen Transform. Than it is to the elegoo Mars sadly.
My university colors are being shown on those bottles! (Virginia Tech - Maroon and Orange)

That is Poetry. Alliterations are awesome. :-) :-)
2K for the SL1? I'm out to see a review on the elegoo cause price already got me in.
does the tilting bin, lead to less failed prints?
I wonder what would happen if you UVed the used IPA? Would the resin cure and fall to the bottom?
Really want a GIF of the first 20 seconds of this video for some reason.
Watching the teleprompter reflection scroll on the printer shroud.
@Thomas the reflection of a text sliding is reflected on the printer hahahaha... anyway gj
Polarising filter to fix that prompter reflection?
You need to either print in material that is viewable under the light you use or just spray it with a primer.
@thomas salanderer hey ive been watching your videos since i started printing i currently have a cr10 s5 with octoprint set up but recently ive ran out of space octoprint says i dont know how to delete such files ive deleted all timelapse videos but still says i have no space left could you lend a helping hand and guide me thru the necessary steps to correct this issue? thanks in advance
Ever heard of the form 3?
Love the autocue
What are we to do with all the used isp?
Good review, touches on some key points. I'd like to see a comparison between SLI and Mars. I have a Mars (because it was cheap, let's be honest). I also have an MK2.5S, so it'd be great to see what I'm really missing out on (if anything).
Damn you shiny objects!!! (Shakes Fist)
1:26 nice autocue :)
I found the Longer 10 to be substandard. The Mars has excellent resolution for its small build factor, but I've found the dimensional accuracy to be off by approximately a millimeter. I'd like to know that accuracy on the SL1.
I'd suggest trying Siraya Lab Blu resin. Its one of the most expensive resins you can purchase here in Canada, but it can produce functional parts that are also more impact-resistant compared to other resins, and the parts can even have some flexibility to them. As for dimensional accuracy, its my understanding that you definitely shouldn't be having those kinds of issues using that resin. Hope this helps you!
@@HighbridgeD do you think it's the resin causing the deviations in my parts or the print settings?
@@WGAJeremy I'd be willing to bet it has more to do with the chosen resin than your print settings. Standard resins will produce better dimensional accuracy compared to flexible resins for example. But it could be a combination of factors. If your lifting speed in your slicer settings is set too high for the resin you are currently using (say, flexible resins), you may find that over time part of the print will end up being warped or bent as it is being pulled out out the vat. A final consideration could be a lack of support structures for certain sections of the print. It can be time-consuming and tedious, but manual support placement may need to be done as well. This is all I think of off the top of my head, hope it helps!
I don't get why the touch screen is directly under the resin vat. It would make a lot more sense to have a separate control box for the screen, so you don't risk contaminating it with resin
Would you share the file for that orange pi case you showed?
Is there a concern that the tilt mechanism will eventually go out of alignment and need manual readjustment? I can see this being a problem with other similar printers as well (e.g. FormLabs).
It has an endstop built in for zeroing - not sure what else would be able to lose accuracy over time in the tilt mechanism.
Does it come with the teleprompter?
What happens to the video feed around 2:40???
Random clips
How did you get Space force acoustic panels already? Lol
Just a quick heads up for anyone watching this; Prusa just released support for hollowing out prints in the 2.2.0 release of PrusaSlicer.
2020 has been a long year. It felt like the SL1 has been out for 3 years already.
