    Best Quality 3D Printer CREALITY CR-10 Killer for this price officially :)
    My first printer was JGAurora A5 Model. And I took it for a trial. Then I said, let's try some more appropriate models. I found a printer that was about 1000tl cheaper, and I came across the AŞFAVISE U20. I was hesitating at first, but I was shocked when the printer came and printed the first print. 1 month later I will buy the Alfawise U10 model :) What more can I say :) A detailed edition is available in the video. You can see if I open and watch my video from youtube. And if you want to get it, I would be very glad if the video gets over the link below. Step by step: 1- It has high quality metal profile and it does not vibrate at all. (The point where I feared the most) 2- It was easy to assemble (it might look a little against the wiring part, but it is very simple to know, but new areas can work for half an hour :) 3- Heated table is very good to be even other stylish right below: 4- Glass exchange of the heated table is better. In other printers, unfortunately, the heating surface with the glass is adhered and therefore the change is very troublesome, but it is not. 5- The glass plate surface was really good. You can change your mind when you see that the filament is sticking when printing in poor quality. :) 6- Filament sensor is also a big plus. Because it is expensive in the creality brand that does not exist personally. 7- When filament ends or needs to change, printing can resume. The Creality CR-10 doesn't have that feature :) 8- Even if Extruder looks small, he is doing his job very well. 9- Nozzle Warm-up time is very fast in 20-30 seconds and is ready for nozzle printing. The plate warms up later. 10- Z axis height of 40cm is already great at this price. 30 million unfortunate creality. The updated version is the same as this, but the room is more expensive than 1000 TL. 11- High resolution printing is very good. I tried the first print with 0.2mm and the second owl print was printed at 0.1mm and was tremendously high quality and fast. 12- With update up to 0.05mm resolution allows printing. Even if you're working on it, even under pressure can give. 13- Touch control panel is the biggest plus. Easy to use interface and provides seamless adjustment. Creality also does not have touch feature :) 14- Table setting was very comfortable and easy. You can adjust the required leveling on the touch screen and enter your hand comfortably under the table. 15- Do not look at the single Z-Axis motor. I had too many doubts because I had a dual z axis engine and I was happy. But there's nothing wrong with that. He surprised me with that. 16- Nozzle and filament cooling was actually better than JGaurora. 17- Z The attachment of the axle shaft to the roof has already been
    Actually, there's not too much. This is not considered as a minus property for this price. But still write. 1- It is much better if there is a Dual Z stepper motor. 2- Cable clutter needs some more edits. 3- It would be better if they made the cables a little longer. That would be easy for the users to make the cable layout. 4- It would be perfect if they increased the price a little and added a BL-TOUCH sensor. Because now I think it is necessary to have Auto level in each printer. But as I said at this price Creality CR-10 SOLID :) Creality friends who know garbage. It was sold out too and the prices were very excessive. It was cheaper at first, but not worth it.

    alfawise u20. it's worth your money.
    I started off with a small printer, to learn how these work before going for larger print volumes.. the u 20 IS THE LARGER PRINT VOLUME. it was easy to assemble, had it together in about 20 minutes. the packaging was great, everything was secured in the box well. I joined the facebook group alfawise u20 and I believe everyone purchasing this printer should, as updates are offered for download to keep your system updated when new things are added... I've had no negative issues with the printer, the heated bed works well and warms quickly. I had my first storm power outage and the power resume worked as intended. it simply warmed up the hot end, homed the x and y and continued printing.. that's awesome.. I would print a spool holder for it as the one provided has trouble with full sized spools of plastic. it works well for the provided spool though.. I cannot wait to really get some hours under this printers belt and watch the great things it prints for me... I love movie props and statues, so this bed size is going to be fully taken advantage of... this is a great printer and the price is nice. join the facebook group, take advantage of the updates and learn from the other nembers, maybe I'll see you there..

    A gift for my son's admission to his favorite university
    My son had asked me to buy an open-frame FDM 3D printer for him, because he loves 3D printing lessons and feels proud of his 3D-printed models. They are something extraordinary. After the admission, I though it might help with his major in the university. Now that my son is interested in 3D printing, he can keep himself occupied before the beginning of the new semester and studied a lot of knowledge. After several long hours prints (about 2 - 3 days), he gave a positive review and put it online. According to him, the nozzle will not be clogged and the printing quality is great when the extruder is working at a high speed. Indeed, the details of the models he made are fascinating. What he likes the most is the combination of printing directly from Micro SD card, filament run-out protection and power cutoff protection. Because 3D printing takes much longer time, these three features help to avoid any possible imperfection and restart. He thought the problems are not a big deal and many can be easily fixed. For example, he replaced the cooling fan, and ignored the scratches on the gantry caused during the shipment.

    Competitive Large Build Volume 3D Printer
    I waited 2 days to get my first print which takes up the full size of 30 x 30 x 40cm. It is incredibly perfect. Certainly, there exist some noise which is unavoidable for FDM printers. The better the filament you use, the higher printing quality will be. It takes me only 6 minutes to finish connecting the frames and the cables, although I did not have a look at the instruction. This is because there are labels at the end of the cable, so what you need to do is only to match them. It is easy and time-saving! I also like inserting a TF card to print, so I do not need to keep the computer operating for tens of hours. As to its disadvantages, the 3D printer had not been packed well, although everything inside is intact. Different parts needed to be separate apart. Evidently, this is something that you should think highly of.

    The best quality / price printer today!
    -All the printer is built with metal parts, which gives a great consistency. -A single motor in Z, so that desynchronisations are avoided! -Electronic of 32bits with 24v source and touch screen. Isolated printer electronics. -Extruder of short distance, with built-in layer fan. -The hot bed comes with an adhesion plate for the printed pieces, buildtak style. -Vslot wheels on all axes, so it has a great smoothness of movement. -The extruder is already modified with a filament sensor. Filament on a stand to put on the table. -It comes fully equipped, with tools, a 200gr coil of gift pla and a needle to unclog the nozzle.
    -The only thing is that the firmware is closed, waiting for it to be released.

  • Will it come with filament?

    It comes with 200g PLA filament.
  • Why the filament can't stick on the heat bed?

    1. Paste high temperature adhesive tape on the heat bed or using 3D print heat bed glue. 2. The distance between the nozzle to heat bed is very important, please keep the distance is about 0.2 - 0.3mm. 3. Some types of filament need higher temperature of heat bed, usually PLA is 50 - 60 degree, HIPS/ABS/PC is about 80 - 105 degree.
  • Extruder cannot heat up to setting temperature, what can i do?

    1. Check the blowing fan is on off or not when extruding, if on please turn off it first. 2. Check whether the heater wire connected well or not. 3. Disconnect the heater from the control board. test two ends of heater by a multimeter(using resistance grade), if resistance is over 10 OHM, it means the heater is broken.
  • How do I know the links to update the firmware? If SD card data is lost, how can we find it?

  • What should I do if I cannot resume printing after power shutdown?
