    First off, this machine is just amazing for someone new to 3d printing. it has easy super easy set up, easy maintenance, . easy cleaning, the quality is great (look at the none failed parts of my prints)…when it works. I say this because I had a lot of failed prints, however it could be a poor operator. i noticed that i would burn through FEP screens fast too (lucky to get 15 prints before they went bad, keep in mind, i had a lot of failed prints. i think a major reason i have had so many troubles printing is because of a bad LCD screen, and of course i am new enough, i dont know to look. after a long research session, i did find out my LCD screen was broken. One thing for sure, keep an eye on your LCD screen.i am happy to say that LONGER has agreed to replace my screen. it took a bit of time and a lot of emails but if they actually send them, ill be happy. I’m sure replacing those will be a bit more work, but i can be mad for a company replacing their parts under warrenty.***UPDATE***I have received my replacement parts. I want to thank LONGER for standing by their products. Thank you and happy printing everyone!!!

    UPDATE:So I received the new unit, and have been cranking out awesome prints, now that the FEP film issue is resolved. I am quite impressed with this printer, since my last frustrated post and haven’t had a single print failure that wasn’t a user error. Check your components before use, and follow all the recommended guidelines and this printer won’t let you down. Also thank you to the customer service for the prompt reply!!OLD POST:Firstly let me say, the first 3 prints on this printer were fantastic. However it appears when the original FEP film was installed not quite right, or perhaps had a loose screw, or small tear on the one I ordered because on the fourth print resin leaked out of the side of the vat and down the machine. So I replaced the FEP film and spent another couple days of failed prints, before I realized the screen underneath had cured resin on it causing constant failures. Now I have a printer that’s a couple days old that cant use.the quality that this printer can produce is top notch if you not ruining components out of the box, but now I’m going to have to buy a new LCD and replacement FEP film and I have barely had the printer a couple days.

    Okay, this is going to sound a bit fan-boy-ish, and I guess I should be sorry, but I’m not. I’ve had this printer for over a year, I’ve chugged gallons of resin through it, I’ve printed to the limits of the vat – and I LOVE IT.I haven’t pushed anything at it that it couldn’t handle. Everything I’ve printed on it has been fabulous. This includes (but is certainly not limited to) expansion parts for my FDM printer; miniature models for gaming and just for fun; and about 200 different items of varying value from Thingiverse.Tech support has been amazing as well – in my haste to learn more about the printer I broke a part, and they have bent over backwards to ensure I was back up in no time. 10/10 – would deal with again.Now, the LongerWare software is not the best – but the ChituBox software that is available with an Orange plugin, that’s great.Now, here comes the bad part.18 months after buying it, and using UV to bake my output, I discover that it IS possible to overcure your prints and make them exceedingly fragile – which I have done TO EVERY SINGLE ONE OF MY MODELS.Well, better to learn now than later.

    I bought this and elegoo standard gray resin. I used prusa slicer to make supports then longerware to slice the STL. This printer is awesome.I was going to get an Elegoo Mars Pro. Like would have clicked buy and fed it my credit card. But they are having supply issues. I’M SO GLAD. Turns out the Mars has an improvised coupling for the Z Axis stepper motor. Looking at the pics for the Longer, its proper coupling is on display in the middle.After opening the box on my table, I did TWO things:1) Level the plate using two strips of paper. Turn it on, lift up the plate, unscrew and remove the vat, and loosen the screws holding the build plate to the arm. Have it go to home, then I tighten the screws until the two sheets of paper evenly pull out from under the plate. Mine feels slightly tweaked to the right but I can get it to tighten so there’s even pressure by only screwing in the screws 1/4 turn at a time.2) Before putting the vat back in, I wiped the FEP with 3-in-One PTFE lube, then wiped it until it seemed gone.Pour in the resin to half way and BOOM you’re an action hero maker. Been printing for a week+ non stop and it is really amazing. Elegoo standard resin isn’t real bad … printer is in the side of the living room. Phrozen Green is a touch stronger, but not bad enough to get my wife to tell me to move it somewhere else.

    As an individual who has been a hobbyist 3d printer since before you could even buy them assembled and programmed, this was a fantastic purchase. I have literally never done so little set up, programming, etc and had the quality of prints this machine has provided in less than 48 hours since purchased.The only cons I see so far are these:1. The uv resistant housing is very cheap and held together by rubber bands that rest on a sharp acrylic edge- this is an easy enough fix, but still needs to be mentioned.2. The touch screen is slightly undersized for this application and to be the only method of control it can occasionally be difficult to navigate (not particularly responsive, small icons to press even with small fingers like mine)3.My particular printers FEP film was already covered in small abrasions when unpacked- does not affect the prints, but seeing as to how it is listed as “consumable” ,I wasn’t done any favors with it being damaged out of the box. It can’t be good for the life span of the film.Other than the items listed above I am satisfied. if that changes, rest assured that I will update my review.

    I give this printer 5 stars based on it’s price/performance ratio. It is a great value for the money. I like this printer better than the Form2, which I also use. It’s just plain easier to work with and, on the whole, it seems a bit more reliable. But, that also has something to do with the fact that having the Form2 taught me a lot about orientation, support generation and starting layers.The resolution is very impressive and the only failed print so far was one of the pre-sliced files (Star Wars skull.lgs300) on the USB drive that came with it. The BRACKET.stl, also on the USB, printed beautifully. I suggest this be the first file to print. I sliced that with the default settings.I have other prints that must be completed for a deadline; but, once that is passed, I can retry the other supplied parts to see how they perform. I will also clean up some prints and post them. So, far all of us in our 3D print lab are very impressed by how well it’s going with this printer that is SO affordable!When I have time to keep an eye on it while printing, I will try to print something that fills nearly the entire print area just to see how it handles the weight of large parts. But, I am very optimistic about its ability to get the job done.YouthQuest Foundation purchased this printer simple to give our students experience with a resin printer. Not a single print failed and one of the prints was 142mm long! As with all SLA, removing supports is something to be considered. See photo.Being brave, I decided to test it using AlphaSense Ceramic Resin. (It requires having a kiln). Miracle of Miracles! It worked with adjusted timing and supports. I have NO idea how it would affect the life of the printer due to longer print time; but, this little printer did an amazing job with very demanding resin!

    This is my first SLA resin 3D printer and I’m very impressed. The print quality on this machine is amazing! Setup was simple, mostly plug and play. I’ve been using mine for miniatures, statuettes (printed in multiple pieces then assembled) and small detail parts for costumes and props. I’ve already printed a ton on this machine thanks to how fast SLA prints compared to FFF. I would definitely pick this up if you are wanting to get into SLA resin 3D printing. Longer 3D has really amazing support as well!EDIT: In an earlier version of this review I mentioned you needing to convert to a Longer proprietary file format. Well Longer 3D support reached out to me and let me know there is a Plugin for ChiTuBox to output their proprietary file format. They sent it to me directly and said it should be available on their website soon.Great prints, easy to use, solid construction, great support.

    These people are crooks, their machines will break shortly after getting them, then they will expect you to open the machine and start messing with the wires like your some kind of IT specialist. When that doesn’t work and ya want a replacement, they’ll probably just start ignoring you completely. I’ve owned 5 machines from this company. 3 Orange 10’s and 2 Orange 30s. Why so many? Repeated factory defects. The Orange 10s got me about 1 1/2 months of printing ability between the 3 of them. I only bought 2 of the 3 Orange 10’s. The third was a replacement they had to send me because the machines broke shortly after coming out of the box.After awhile, they came out with the Orange 30. And I made one of those “fool me once…” mistakes and purchased one.I pulled it out of the box, set it up, but while doing my first print, the screen went out completely. They eventually had to send a replacement for that machine is well.As soon as I turned it on, I noticed that the touch screen didn’t appear to be calibrated correctly, and I only managed to get one print from it before the calibration became so off that I could no longer press any of the options on the bottom half of the touchscreen. I contacted them but I was also in the middle of moving, so it took me awhile to read their reply. But, essentially it was the same thing they always said. “Take your machine apart and send us pictures and video of it not working, as well as the inside of the machine.” I have ZERO technical skills so they directed me to a YouTube video showing how to take apart the Orange 30 and check the touchscreen connection. But, before I could try, I had a medical situation that took several months to recover from. As soon as I recovered, I checked out the video. Only to find that the machine in the video was not the same model that I had. Both were Orange 30s but the video showed the little access port as being on the bottom of the machine. Mine is on the side. Needless to say, this caused some problems. But, I finally got it opened and INSTANTLY noticed the damaged circuitry on the touchscreen, which is shown in the photo of this review. Regardless, I checked to make sure the touchscreen was properly connected. It was. I put the machine back together but now it won’t even turn on. No doubt I bumped a cable loose or something, while trying to take the machine apart. Again, I’m not a repair man. I shouldn’t have been asked to take apart a high sophisticated piece of technology PERIOD.I sent them this photo along with the same explanation I just gave her.No response.So I contacted them on Facebook. I finally got a reply saying they’d look into it.They then tried telling me I needed a different email address cuz they couldn’t send a response to my current one (odd, considering they had no problem replying any of the other times I contacted them.I told them they either needed to replace the defective replacement or I’d start buying my 3d printing machines and stuff from a different company.I asked the person I was speaking to on Facebook if they could just tell me their response. That’s when they replied by telling me that they “can’t find the support team to reply to my message.”And, that is the last message they have sent. They are now ignoring me on Facebook AND ignoring my emails. They can’t even be professional enough to tell me if they’ll replace their defective merchandise or not. No, they are ignoring me like children. These people will take your money, waste your time, then outright ignore you when you want them to replace their defective machine.

    I bought this to print various items that i sell at a much higher quality and strength compared to my Prusa MK3S.So consider me experienced with slicing models but new to the resin world.I expect to struggle to make prints stick to the build plate and have to tune a lot of settings for quality…I was very wrong…First print (a trawler “benchy”) with the standard Longer Settings in ChiTuBox is absolutely perfect! Better than my best FDM benchy….The printer is a lot more compact than I expected but more than enough build room for my needs… (see in photo the size of the Longer Orange 30 compared to my Prusa MK3S)10/10 recommend10/10 quality10/10 customer support10/10 will buy againUPDATE 6/12/2020:Been very disappointed with this printer…The cooling fan became VERY VERY LOUD, like it sounds like a small jet plane inside the printer. Ok fine I’ll throw a nicer fan in it…Then the orange lexan started to crack and “spiderweb” on all sides.Now I found out my LCD Screen is ALREADY BROKEN!!! Less than two weeks with it and the LCD is broken…Longer 3d support is helpful but everything takes 20-30 days to arrive from them (allegedly… I still haven’t gotten any warranty stuff) so the printer is gonna sit till then… Not going to spend any money on this unreliable, cheap, low quality printer….Two weeks into ownership and I regret buying this printer!!!do not recommend, will not buy again….

    Perfect entry level SLA printer. The price is great, build quality is surprisingly sturdy, customer service has been excellent and the included software is adequate.First of all, I am completely new to any kind of additive manufacturing and this is my first printer. I had a few issues at first, mostly because the model I was trying to print was particularly demanding as it was a large flat object that filled the entire build space. Customer support helped me quite a bit explaining why my print was failing and helping me resolve it.During this process I found out that the actual build space is slightly smaller than advertised due to assembly tolerances, so some printers will be better than others. My actual build space is only 64x118mm instead of the advertised 68x120mm. Not that big of a deal but a little disappointing.The included software is good enough to get the job done but unfortunately does not let you save your files in a way that can be modified later. You import a model, orient/scale it on your build platform, add supports, set your resin/UV light settings and then slice and export to the proprietary Longer3d format that the printer reads. Pretty easy. But if you want to modify any of those settings you will need to start all over from importing your model.I quickly abandoned their software in favor of Chitubox, which can export to the Longer3d format with their plugin. But in my experience getting the plugin to work properly was a real headache. It seems to be hit or miss from what I read about others’ experiences.Once it’s all dialed in the prints are phenomenal. More-so than I expected, honestly.Like with most things, it takes a bit of tinkering to get it working properly but is worth it in the end. Also be sure and keep safety a priority when working with resins. A lot of planning is necessary to keep from making a mess.
