The Super Speedy, Sensual SL1S - Resin 3D Printer Review

The Prusa SL1S is the fastest MSLA resin 3D Printer I've ever tested, but is it worth the hefty price tag? I still think the S should stand for sensual though.

That intro has me dead. The banana shirt seals the deal.

Did mine as an upgrade from the SL1 and I was shocked how large the UV lights are compared to the past version. And I LOOOVE mine.

God that purple black color combo is insanely gorgeous omfg. I donno what about it makes me feel incredibly into it

[DinnerSonic]

"Wait, the S doesn't stand for sensual?"

"However, I do get to do *whatever I want with the machine* now that the review's done."
Should I be... concerned? 😂

I've been running one of these for the past two months - fantastic machine. I went with this specifically because of the ChiTu situation. It's pricey but super convenient and reliable. I have three EPAX machines and I barely run them anymore - the SL1S is fast enough that I can get most things done on it. (I likely would have never purchased the SL1S if EPAX machines weren't locked down to Chitubox.)

Regarding the resin sensor, I've found that the machine needs to power on to lift the plate and vat, and even then a slight nudge is necessary to bring the vat to be level with the printer plane. Only then can you fill to the 100% mark. I wish the markings inside the vat were a contrasting color, like white, so they were easily visible.

"It's rocking a monochrome LCD."
I see what you did there!

I have no doubt that the SL1S is a great printer, but it's disheartening to see other printers that cost much less but print just as well being overlooked by the bigger 3D printing channels. The Anycubic Photon Mono has the same build volume as the SL1S, same cure time, same size screen, and it's not locked down to Chitubox either, and it costs a tenth of the SL1S. You can also bundle it with their wash and cure product for almost a tenth of Prusa's offering. The SL1S has a lot of fancy additions that Anycubic doesn't currently have, but if Ender 3 clones can get loads of coverage, budget friendly resin printers should too.

I love the fact that in the opening bit he used a battery bank instead of a phone.

"A box with tools, spare parts and consumables"
A bag of gummy bears?!? For a 3d printer?!? Oh, get it, *consumables*

[KeithOlson]

Great review, as usual. Some thoughts:

1. As the case appears to be ferrous, you can make a lever-style switch extension that can be attached to the case with magnetics. (Like emergency stop switches have.)
2. A microphone could be added to the case that listens for the audio spike from peeling--triggered by the vat being tipped--which then alerts you to check on things if it isn't heard.
3. Stubby USB drives can cook themselves to death a *LOT* easier than a regular one, so a right-angle USB adapter to hold regular drives flat to the case is pretty cheap insurance, especially if you get magnetic versions that will pop off of the case if struck.

Does that make sense?

Came for the printer, stayed for this banana shirt!

I have had similar issues with pressing buttons with gloves on, Prusa is not the only one using that style of button. My solution was relatively simple, but works. I printed a button extender. It is basically a ring with the ability to fit around the bezel and then a shaft going through the ring with a stopper end. So basically it is a 10 mm piece of plastic inside of a ring that is held down by thr bezel. For less aestethic situations, I just glue an M3 bolt's head to the button.

Yes, I was looking at printer options.

Thank you for continuing to do what you do under the circumstances. My heart is with all of you!

[ReedCBowman]

Would love to get this but that price... I would really appreciate an opinion of the Anycubic line, which is all on sale for astonishingly cheap right at the moment. And their new system that just kickstarted too.

[Jeffmorgan]

Can't wait for this technology to become affordable!

[dtechnologies]

Dude you hillerious! Waiting for prusa to make something big enough for me to use is like waiting for simplified 3d to update their slicer.

[notjannet]

Okay, 3 seconds in & I feel the need to comment on how awesome that shirt is. Okay, now I'll continue with the rest of the video.

[justme]

The should call it the SE for super expensive! It looks very nice but at 3x the cost? Also dlp is becoming affordable so this is almost out of date already.

[NellShamrell]

Thanks so much for detailing how to fix the print sticking to the resin container - I just got an SL1S and had the exact same thing happen with one of my first prints. I remembered this video, navigated back to it, and learned how to fix it. Ty again!
