Hi hassanloay1536, I have not had the chance to test those specific printers, but I assume they are all pretty good. I would recommend you do not make your decision based on the resolution of the printer, all of them have more than enough resolution to print dental models and all the details needed. I would even advice you to avoid the higher resolution ones, as they do not give you any real benefit to dental and may be more expensive, energy hungry and may require more time to process the files. I would also recommend you go for a slightly larger printer, like the Elegoo Saturn, you will have more room to place your models. From my limited experience with all of these lower cost printers, I believe Phrozen have higher machine quality, then Elegoo and finally Anycubic, so Eleggo is a nice middle ground of good quality and good value. My final recommendation is that you start as soon as possible, you need a lot of actual hands on experience to truly learn how to use this technology, and that experience is far more important to get good results than the printer you buy. Good luck!

Hey Marco. Nice video very insightful and helpful. I've been 3d printing for a couple of years and have several printers but have been meaning to try to start printing for some labs in the UK. At the moment I have 4 anycubic mono and mono x printers. Do you think I would be able to use them to do some small work for labs while saving up for a better dental 3d printer? I know I won't be able to print loads of dental things labs would want. But if I stick to items like the one you showed in this video? Unfortunately I have had health issues the last few years which means I do not have the money to invest in a £5000 from the get go. Could I use the ones I have? And I did need to buy something to be able to start printing for labs for under £1000 what could I get? Would a small 3d scanner be good enough to check the printed item to the original scanned one? And what resin would be good? I see you used standard grey which is what I tend to use. But would that be okay for these items? Since they won't be in contact with the patient and only with the lab there shouldn't be a problem with toxicity right? Let me know please and sorry about all the questions. Wish I could pick your brain a bit. Cheers, David

Hi R&J, You can always go the traditional way and get an alginate mod and plaster model, then use a much more inexpensive scanner. Good reliable scanners are expensive, there are no really good and cheap alternatives. The only company that comes to mind that may have a bit cheaper scanner options is Shining 3D, it is a chines manufacturer, but I have had good and bad experiences with them, so I can't really recommend them at this point. Companies like Artec, Leica and even 3Shape offer lab scanners for dental paster models. They may be a bit less expensive, but are more efficient, but not as convenient as directly scanning from the patient.

Hi Vincog, There are specialized resins sold to print temporary dental crowns, be very careful when choosing the resin, it must be compatible with your printer. You also need to follow the recommended workflow for those resins, I would recommend using the printer ONLY for that resin, to avoid contamination. I would also advice you to test a lot with standard resins before, you should practice with cheap resins and make sure you are getting great reliable results before investing on those expensive resins.

Hi JoonKimDMD, If you are only starting and will use the printer for professional work, I usually recommend a prosumer 3D printer, I like Formlabs, the new Form 4 looks amazing and is baked by a company with a long history of reliable printers and easy to use software. Once you have a good, reliable printer, you can start considering other cheaper alternatives for grunt work and backup. There are three leading brands in the entry-level category printers and resins. Anycubic(cheapest in price and quality) Elegoo(mid level) Phrozen(best quality and priciest) If you are going to do surgical guides, I would only do it with a prosumer printer that has its own certified material and processes. It is such an expensive material that you will soon spend more on resin than on the printer itself. If you are only starting and just want a printer to learn, get a cheap Elegoo Mars. It is a small, very managable printer that will let you experiment and learn how the technology works. After you master that printer and you are still interested in using this technology professionally, then buy the Formlabs From 4 and a couple of cheaper printers depending on your work volume

@JoonKimDMD FDM is not a good option for dental work. It is slow in comparison to resin for high quality models. And the accuracy is not appropriate for most dental applications. Cheap resin printers give very impressive models, but they may be slightly distorted. If you have a good quality control system, you may identify the mistakes and avoid problems in your workflow. Cheap printers are also much more likely to fail or behave strangely, and if you are not familiard with the technology. You may have a lot of difficulties getting it to work correctly. My suggestion is to start practicing with an inexpensive printer for non critical work. The Elegoo mars or Saturn are a good starting point. You will need weeks or even months of practice before you can be confident enough to use the technology reliably for professional work. Once you feel confident with the technology, decide which printer suits your needs, and hopefully get atleast two printers, so you will always have a backup. The #1 problem I have seen with the adoption of 3D printing in dental clinics is lack of practice before implementation and the #2 problem is cheap printer failures that block the workflow. So practice a lot and get a backup printer. Good luck.

Hi, why you wait half an hour to dry the models? Is it necessary or you can steam it or clean with air?
@MarcoDeRossi
2 жыл бұрын
Hi Tomasz. I prefer to wait a bit until it dries for many reasons. First i can tell if there is still any uncured resin in crevasses, uncured reain ia shiny while cured AND dry resin is usually not. I also like to see the dry model to verify everything is ok and there are no damages or print problems. Also, the material absorbs the alcochol and it expands slightly and makes it more delicate. So I prefer to cure and heat it once it has dried a bit to avoid surface tensions that might crack or deform the model. This varies depending on the quality of the resin, but I think it is a good practice. Also, I prefer to avoid touching the model until it has dried, as the surface can become very delicate and even a slight touch may damage the surface of the model. I would encourage you to experiment with your resin, if there is a benefit to waiting until the model is dried, if you do not see any benefits, you can skip the wait or make it shorter. Good luck.

Meshmixer is probably the most difficult one to get two models to aligned for comparing. In Meshmixer you basically have to position it manually and then select both models and go to analyze>deviation and select your acceptable deviation.

Hi Peter, Temporaries are a bit more complex than dental modes for aligners, as they come into contact with the patient. Temporaries and permanent crowns need to be made using certified materials, equipment and processes, at least according to regulations in many countries. There are a few manufacturers that offer materials for Temporaries, and you need to print them with their printers and follow their instructions for postprocessing. Envisiontech, 3D systems and Formlabs offer resins for temporaries, not sure if they are compatible with the Elegoo Saturn though, and the will certainly not be certifiable.

You can calibrate it using a sheet of paper without the tank. this allows a small gap between the platform and the LCD screen for the FEP sheet and a bit of resin.

Hi Paphos, This video was done with the original Elegoo mars, the new versions have similar surface quality and definition, their greatest advantage is the speed of printing and the duration of the LCD , thanks to monochrome LCD panel technology. I believe that if done correctly, these printers have the quality and precision for smile mockups, the problem would be biocompatibility of the resins used if you plan on placing them on the patient. I am not aware of a compatible resin that is certified for brief human contact. These resins can be very irritating if uncured, so the absolute minimum precaution for using non certified resins would be to thoroughly wash the parts with clean isopropyl alcohol and properly cure the part and avoid contact with the the patient skin or lesions. In any case, you should check you local regulations, and do all you can to find certified resins or resins that have been tested by others for a similar use. Good luck

Hi Daniel, There are two general ways to get the 3D scan of the teeth, one way is to 3D scan a plaster model, very common in dental workflows, there are MANY 3D scanners for such a purpose, many are used in other industries, as taking a 3D scan of a bright, mate finish static object is not particularly difficult (look for structured light scanners for example). A more novel equipment (and also usually more expensive) is an intraoral 3D scanner, they are specifically designed to 3D scan the patients mouth, which is hard to reach, shiny, moist and moves a lot. There is one extra step that can be quite important for some dental workflows, and is to capture the "bite" or the relative position of the upper an inferior teeth when the patient is biting. This can be done with the intraoral scanner quite easily. Some scanner reference you can check are: shining 3d, Artec, 3Shape.

Hi Jayson. The Elegoo Mars is not certified for dental crowns, not sure if that is a problem for you. I do not even know of any permanent crown material that would work with the Elegoo Mars or similar printers. If you want more information about a printer that can do so, check: dental.formlabs.com/indications/permanent-crowns-guide/ As for the designs of the crown, it is usually done with a dental design software. If you do not have a dedicated software for dental design, you can use a model from the internet (there are many free models, look around a bit until you find what you need). With the generic design, and the patients 3D scan, you can make the design yourself using a software like meshmixer(free) www.meshmixer.com/ But you will need to learn how to do it correctly, and it takes time and practice, it is much more difficult than what people think. Keep learning and I wish you luck.

Hi Marco. Which 3D Printer will you recommend for dentistry?
@MarcoDeRossi
3 жыл бұрын
Hi Daniel, There are a few brands that have specialized on the dental market. The printer you buy should depend on the volume you expect to produce and how much effort you want to put in. you have super expensive printers like The Figure 4 by 3D systems that costs tens of thousands of dollars and print super fast and extremely reliably, and you have super cheap MASLA printers that cost less than 200 dollars that might arrive with broken parts. I am a fan of Formlabs, and the Form 3B is a great Prosumer printer that offers a balance of many good things. It has a big volume, it has great resolution and it is not super expensive, it also has a wide range of materials for dental work and many more seem to be on their way. You could get printers that are cheaper, but will probably have unexpected results, and I would not trust a critical medical application to cheap printers. Also, 3D printing has a steep learning curve, so starting with a cheap printer that might give you problems or that requires a lot of practice and learning may not be the best option for you. My suggestion is that if you are only curious about 3D printing and do not want to spend a lot on an expensive printer, you can start with a cheap printer, like the Elegoo mars, see how it works, practice and make mistakes. Then if you think it is right for you, you can invest in a Form 3B Printer and get better results with less problems and only then start offering the service to your customers. I have seen MANY dental labs and clinics that think that buying the printer is all it takes to give the service, and start to offer their prints before they even know how to use the machine. Let me tell you, their clients were not happy. Good luck

Hi Alfredo, The Elegoo Mars series printer can achieve good results for most dental model applications. If you use good quality resin, correct printing settings and careful post processing, the model accuracy is very good. The printer is just a "dumb" tool, you need to make many decisions that influence the process, and if you do not know what you are doing, you will have many failures and problems. I have had good results with the printer, but 3D printing is only half of the process, you also need to have a good 3D design software that can generate useful models for the specific application that you need. For crown and bridge work, you need to fix the 3D scan from the patient, then model a guide to help keep the alignment, and also also design the removable dies, also add the name or code to avoid confusion. You can use Meshmixer to understand the process, but there are professional software that makes the process much easier. I believe these kind of cheap printers and free software are good to start experimenting and understanding the process, but I believe that for serio, check to see all the possible us professional work you should invest in a professional printer and software that is a bit "smarter" and will avoid a lot of problems and give you more consistent results. The printer I use for a certified process is dental.formlabs.com/materials/ check the Model Resin to see the kind of model used for crown and bridge designs. Good luck, keep learning and start experimenting to understand if 3D printing is right for your case.

Hi Brad X. Considering how inexpensive high resolution resin printers have become, I would not use FDM printers for medical purposes in dental work. But I have done a lot of models for training with good results with a well calibrated FDM printer. If you really want to use an FDM printer, I would start by tuning the material temperature and doing a fit test, to make sure you have a high dimensional accuracy and correct any deviation by expanding or contracting in your slicer software, Also use a smaller nozzle, a 0.3 or even 0.25mm nozzle wil improve significantly the small detail definition. I would also try and scan your models to see what accuracy you are achieving to help you determine what kind of dental work might be appropriate.

You may consider using supports and placing the model at 45 degree angle, this is actually the recommended by many printer manufacturers. Good luck

The main problem with cheap technology is that you have to verify the results every time to make sure the printer or the technician did not make a silly mistake. More expensive machines have more sensors and better processes to guaranty good results even if the technician does a poor job. I would absolutely recommend the Elegoo Mars to someone who wants to START learning dental 3D printing or already has a more expensive and reliable machine and printing experience. I would not recommend it if you are looking for a reliable hands off machine that does most of the job for you, and to start using it for your business quickly. hope this helps!

The settings change a lot depending on your 3D printer. I usually start by creating a standard profile in chitubox for my printer based on the standard resin, I often use 0.075mm layer height, but even 0.1mm for aligners should work. One parameter I often change is the lift speed, I like to lower it to half the recommended speed, I find this reduces the chances of deformation and support failure. Another factor that influences quality a lot is the position of the model and the settings of the supports, models should be printed or completely flat, or at a steep angle, 60 degrees is a good value. and supports should be plenty, I use medium size supports and increase the density to 80% and the angle of supported surfaces to 65 degrees. Hope this helps a bit, good luck with your tests!

Thanks for the in depth analysis. Ive struggled with accuracy of SLA prints in the past myself; and I think the main problem was resin shrinkage. Now if that shrinkage was nice and uniform over the part it should be easy to correct for with a scaling factor; but with the curing station as you have it (not very uniform light; no rotating platform), shrinkage is likely not to be uniform and the part will warp as a result. Have you tried checking the fit before the post-curing, and did that make any difference?

4 жыл бұрын
This is not an adequate printer for surgical guides. You need a printer and material combination that is certified. Like the Form 3 using SG resin. 3d printed Surgical guides need to follow a procedure to guarantee they are safe to use. The material must be well stired, the printer needs to cure the resin properly and accurately. Then you need to clean it with fresh isopropyl alcohol and cure it with a heated chamber an UV lighting. All that said, you could conceivably print a surgical guide with this printer using a 405 nm LED biocompatible resin and might be able to use it in your own clinic depending on the regulations in your country. If you do, you should scan it to make sure it is accurate and clean it thoroughly and cure it very well. Still I would try to stick to certified equipment, materials and procedures for such a delicate product as a surgical guide.

You can also try industrial scanners, they will probably be cheaper, as many companies charge a premium just to ad "Dental" to their products. the famous dental tax. some industrial scanners might require a bit more training, but the should be just as good, look for the accuracy of the scanner, anything below 0.25mm will probably be fine for dental aligners. New good quality scanners can have 0.1mm accuracy, which I think is better for other types of dental work. In any case, every dental lab has different requirements, so you will have to see which one is the one for you. good luck

Hi Marco. Very interesting video. So, you don't recommend this printer for dental usage? Do you think the problem lies in the cheap resin, or in the printer?

Hi Rui, This is a great printer, and it could be used for some dental work, but you need to have a way to verify your results and have a good work flow. I have had better results with this printer than with a printer 10x more expensive, but I still do not trust it and check the results every time. I would recommend this printer as a second printer, to offload some work from your main printer.

@@sgru9558 Hi Sgru z, These low cost machines can be unpredictable and are not certified or have any significant automated procedure to guarantee safe and reliable results. But they are good machines that with proper use and care can give amazing results. The Elegoo Mars Pro mostly improves on user confort, more than reliability or actual print quality. I would recommend the Pro where noise and smell may be an issue, other than that, it is not such a significant upgrade. As for dental work, these machines should not be used as your only printer for precision and delicate work, specially if you do not have a way to verify your results. But as a second printer to offset some of the less critical work from your main printer is a very compelling purchase.

How did you get the 3D impression
@MarcoDeRossi

Hi initial JB, The 3D impression is taken using an intraoral 3D scanner. There are many brands and they are becoming more inexpensive. Yo must dry as much as possible the teeth of the patient and scan the lower and upper arch independently. You can also scan the bite, to position both dental models correctly.

@@MarcoDeRossi do you need to be a doctor to use the intraoral scanner and it’s software. I’m thinking of buying one as a hobbyist. I’m not sure if I need credentials to use it.

@@InitiallyJB intraoral scans are a bit too expensive to be used just as a Hobbie, probably upwards of 10.000U$. There are cheaper alternatives to intraoral scanners. You can have a plaster impression made with a traditional method and then scan it with a high resolution desktops scanner. Depending on the purpose, you may need to be a dentist or dental technician to make dental models. If you want the dental models for practice or sculptures, you can even use photogrammetry to scan plaster models.

How many minutes do you cure the models?

Hi Ao Xie, I only left it for 1 or 2 minutes, just to make the surface hard enough to avoid accidental scratches. But this process is not absolutely necessary, it can even slightly warp the part so it should be avoided if you don't feel you need it. Some processes require more strength from the model, others need better accuracy, so you will need to decide if you need this step or not.

Che resina usi?

Ciao Andrea, A me piace la resina grigia in generale, è un colore che permette di visualizzare bene i dettagli e gli errori. Io utilizo resina di Formlabs per la mia Form3 Ma ho provato la resina grigia di Elegoo e va piuttosto bene. Ho sentito dire che la aqua gray 4K di Phrozen e la Epax Hard Gray sono anche molto buone per i dettagli.

Hi Ali, The model was captured with an intraoral 3D scanner and exported as a .STL file. It was then imported into MeshMixer which is a free 3D modeling software, and it was then prepared for printing in Chitubox. There are many other software that you could use, there is Blender which is free and more powerful than MeshMixer, but it is much more complicated. there are comercial software aswel.

what's special about dental resins?
@MarcoDeRossi
4 жыл бұрын
Hi Broom, There are hundreds of different "dental"resins, some are probably just a normal resin with a higher price, but others are optimized for exceptional detail and accuracy at the expense of other qualities, like color, toughness or print time. I would classify dental resins into different groups: 1. dental model resins: high detail and accuracy for traditional dental lab work( crowns, thermoforming aligners, etc) 2. Dental Surgical guides: these are bio-compatible resins to make guides to guide dental surgery, like drilling and cutting, these are probably the most expensive and most regulated. 3. Denture resins: these are for temporal or permanent dentures and crowns, they can be found for printing the gum and different tones for the teeth. 4. Clear aligner resins: these can be for hard splints, occlusal guards or aligners Check some specialized resins here: dental.formlabs.com/materials/

Hi José, There are many options depending on your needs and budget, If you want it as your main printer for professional dental work, I would suggest a more reliable printer, I personally use and like the Form 3 by Formlabs, it is a certified printer with great surface quality and relatively big printing volume. I would not recommend an inexpensive printer like the Elegoo mars or the Sonic as your main printer, although they print well, they can be sometimes unreliable. For professional dental work, it is far more important the reliability and accuracy than more resolution. But the printer is just a tool, you also need training and practice to do a good job, You may have great and reliable results with an inexpensive printer or horrible results with an expensive one, depending on how you use it. If you still do not know if you want to invest in a professional grade printer, you might try with an inexpensive one, you will learn a lot and will probably have problems and understand the importance of reliability, and once you decide to move up to a professional printer, you will be able to use it much more easily. Good luck
