Hello, this is Herb Chaparral, aka Dr. Vats and I’m here today with a very interesting meta review. I’m calling the Sometta review because I’m going to be comparing the Ender 3 the under 3 Pro and the Ender 5 I only own an Ender 5 so my observations about the 3 and the 3 Pro are going to come from other reviews and from the Cree Allottee website. In addition, one of my observations is about geometry. The geometry of the Ender 5 is different than most I 3 style, Prusa i3 style printers. In fact, the i3 style was not originated by Prusa, but they’re the most famous manufacturer using that style, so we’re going to talk about the difference between the Cartesian styles of the i3 and the Ender 5 Okay, hold on, lets. Get ready to learn something together. [MUSIC] [Applause] before we get started talking specifically about the Ender printers, let’s talk for a moment about printer geometry, all Cartesian printers printers that use, in essence, a square set of dimensions work on the same principles. They all have an X, A Y and a z-axis, and we all remember this from our days In Euclidean geometry. The difference is which components of the printer are used to move each of across each of these axes. Now let’s think about a print. If we think about a print. It is created layer by layer if there’s 200 layers or 300 layers or 400 layers in a print on the z-axi’s, the access going up and down, they’re only going to be 200 300 or 400 movements, however, if we watch our printers and we watch the print head on the X and the Y axis, there are hundreds of movements per layer, so even if you had a hundred layer model and you only had a hundred movements on the X Y access by the time you multiply that by 200 layers, you’ve moved that printhead a hundred squared times, which is why the orientation of a print makes a difference if we look at a good quality printer, the movements between the z-axis on a typical. Cartesian printer are the most consistent and layer to layer should be very, very consistent. This is the case on the Prusa printers or on the Ender 3 the Ender 3 Pro because we’re only moving the z-axi’s the number of times that we have a layer, 200 300 400 500 It is a much more consistent movement and therefore, if we want the smoothest face, we want to Orient our print so that that face is going up and down the z-axi’s on the other hand. If we look at the face, this is a dr. Vax coaster instead of making maker coins. I make coasters if we look at this. This was printed in this orientation flat on the Prusa i3 which is a typical Cartesian printer and the top surface is not very consistent. You can see all of the individual print heads on the other hand. The side is very, very consistent, so something to think about. So what is the difference? Well, in the end or five, the printbed moves up and down That means it only moves once per layer on the Ender, three and three Pro or on the Prusa printer, the print that is moving back and forth rapidly. It’s moving on the y-axis and we’ll see on a particular layer. It might move many times now. Why does that matter because print patches are heavy prints that have a lot of metal versus the hot end as an example on the Ender printers, which are very light because they’re bowed in style hot ends, There is no Stepper motor on the high end, they’re very light so from a geometry point of view, the major difference between the under 5 and the 3 and the 3 Pro is the geometry and theoretically, it appears to me that would give the under 5 and advantage in print quality now in the initial prints. I’ve made they are excellent. They are excellent and the differences that where as on a traditional printer Quartet Cartesian printer, where the proof that’s moving back and forth, you want that movement to not affect the quality of your print so often you will position your prints in a way so that that moved is on fewer surfaces and so the surfaces that need to be the most consistent. Now you’ll see the layer lines, depending on your layer height, but they should be very consistent. You’ll position on the Z Axis. Okay, let’s switch to the screen now and take a look at all of the characteristics of the under three, three Pro and five and do a meta review of these printers, okay. I’m going to shrink down into the corner of your screen. The majority of your screen will be this table that we’ll use to talk through the printers. I’ll go through this rather quickly. All of this material is available in other reviews on Youtubes from third parties from other parties, it’s available on the Cree Ality website now. Creole D has two websites a the USA website that I find doesn’t list all their products. I don’t know if it’s directly associated them. How it actually works, but if you go to. Crayola t3d onlinecom. The website you see listed in the bottom corner of this page that has all of their printers. That’s where I print purchased my Ender Five. The under fives appear to be in limited production because I’ve only found them on at a couple different locations, including directly from the website in China. I ordered mine from China. It came in less than a week. It was remarkable! How good logistics is nowadays. So let’s start at the beginning geometry on the end or five. The printbed moves up and down on the Z-axi’s. We already talked about the importance of that on the Ender. Three and three, plus the print bread is a traditional print bread, moving back and forth rapidly on the y-axis. Now some people have attempted to call the Ender 4 which is no longer made in the under 5 a core XY printer that is not accurate in a core. XY printer versus a traditional Cartesian geometry, the Stepper Motors do not move in this case. The X Stepper Motor is static, but the Y Stepper Motor is moved back and forth, along with the printhead in a core XY printer. That would not happen so the primary difference. Here is it’s still a Cartesian XY configuration, but the print bed moves up and down. The second difference is the Ender, 3 Pro and the under-five have removable print surfaces. If you’ve never used a printer with a removal print surface, it’s remarkable. Now I do not like this flexible magnetic print surface as much as I like the spring steel print surface on the Prusa. I find that one releases prints better, but this is really dramatically better than a fixed print service. You do have to make sure that the magnets adhere smoothly and you don’t get any bumps in the middle. A build area on the three and the three pro are identical the primary difference with the Ender 5 is the on the Z-axis There’s another 50 millimeters of print area, so you can print taller objects on the end or 5 in fact, this magnetic print bed. I believe is identical between the Under 3 Pro and the under 5 the speed ratings on the under 5 are faster on that really partially has to do with the fact that you’re not moving the printhead bed. As often, it has slightly upgraded a stiffer frame now the difference between the 3 and the 3 Pro is the 3 has the least thick stiff frame. The 3 Pro is a stiffer frame, but it’s an i3 configuration and the 5 has a full box frame. This is a solid, solid frame, So by when you crank up the speed, you’ll get less vibration. The you’ll it’ll be a stiffer surface and therefore you can print theoretically faster with less artifacts, so that on in terms of speed, the Ender 5 has a advantage. The extruder on the original under 3 was a the first generation Ender Extruder, the extruder on the Pro and the five are the same. It’s the new improved MK 10 extruder. It is rated as going a bit higher and a bit higher temperature on the 5 so whereas the 3 and the 3 pro go to 255 on the 5 it says it goes to 260 The primary difference is the bed, the heat that is a different heat bed on the 5 and it can go to a higher temperature, which would be important for certain more exotic fabrics. Also, theoretically, it might be easier to enclose this printer. But if you were to enclose this printer, you have to be careful because the Stepper Motors are outside of the explosion closure, particularly the Stepper motor on the Y-axis is a good oh. I don’t know a couple hundred millimeters outside of the structure, So you, if you were doing enclose it, you couldn’t bolt your enclosure directly to these extrusions. The pro and the under 5 used higher end. Maxwell power supplies the ender threes originally shipped with a generic power supply. I don’t know if that’s been changed. Somebody in the comments can help me with that assembly. The Ender 3 and the Ender 3 Pro are very Ikea. Like if you can put together an IKEA bookshelf, A simpler IKEA project. You can put those together. I found the under 5 a little more complex. There’s more metal to assembler. Assemble the electronics. We’re a little harder to plug in. It does have the advantage that on the printheads of when you get to the leveling step, the knobs are nice and big. It is very easy to level, even though it’s a manual leveling process. Now, Which would I select well? If you’re new to 3d printing, you’re not sure you’re even gonna like it. You just want a printer to get started. I would probably go. If the original three those are heavily discounted on the Web while it sells for $209 on the Cree Allottee website. You probably can get them under on eighty dollars. If you’re looking for value, what you want a removable print bread, which will make your life a lot easier than scraping prints off the bed, You’re looking for upgraded power supplies. A little stiffer frame. The three pros excellent. The next step up basically gets you another fifty millimeters of print height and increased speed. So if you’re gonna be doing a lot of printing and an extra 10 or 15 minutes on a print makes a difference to you. I have cranked this up to 300 3 X speed from what I sliced the print and the prints came out very good, so I believe there’s potential for the five to be quite a bit faster and have more print area, So I hope this meta review was helpful. Please leave comments. I’d be happy to interact with you. I’m interested if anyone has both a 5 a 3 & a 3 Pro to see what your thoughts are. Thank you for joining me at the doctor.
