    Good Printer
    I really like this Printer, it worked right out of the box after about 30 minutes to assemble, mostly took this long because I wanted to make sure everything was right. I have had this printer for about a month now and so far so good. I like how easy it is to use, the bed level feature works pretty well. The one thing I did not like was the existing bed cover, everything stuck too well and would not come off, I tried heating it up a little and it did not help eventually i ruined it by trying to scrape too hard so I ordered some new plate covers after printing on plain glass, and now everything sticks perfect and also releases without issue. I have printed several things and they have all come out nicely. Well, to me they look nice compared to my Tronxy X1. The other day I printed my longest print ever, it was over 30 hours, printed the marble machine. It was pretty cool. See video for some of that print. My camera messed up a couple times so I only got some of it.

    guter Kauf
    Ich habe mir früher ein Video auf Youtube angesehen, also habe ich beschlossen, U30 auszuprobieren. Ich habe dann gleich von der beiliegenden SD-Karte ein 3D-Modell gedruckt. Dies hat super funktioniert. Ich muss mich nun noch in die beiliegende Slice-Software „Cura“ einarbeiten und mir Druckvorlagen für meine Figuren organisieren.

    The best budget FDM 3D printer
    I bought Alfawise U30 after comparing all the 3D printers that I can afford on Gearbest, and I thought highly of the resume functions that other printers didn't have. My old 3D printer doesn't have the resume functions, I left my prints unattended and found a mess many times. It was too difficult to save them so I quitted for a while until I installed a camera and WiFi controller to it. They cost me about $50, but the problem is that I also need to check the process from time to time. In comparison, the filament detector and the memory function are fantastic, a perfect solution to the problems that might occur. The build size of U30 is 220 x 220 x 250mm, enough for most projects, with these resume functions, the value of U30 is higher than the price. I found the tutorials on YouTube about assembling Alfawise U30, and followed it step by step. The assembly is not difficult at all. But it took me about twenty minutes to unbox and check the parts included.

    I've been following U20 and the Facebook group for a while...
    I've been following U20, and the Facebook group on which many people show their printed models and get technical support. When the group name was added '&U30', I was trying my best to find out what is the difference between this two 3D printer. I bought U30 on the very first day when it was on sales, and received it three days ago.U30 and U20 differ in the price and time required in assembly. Not very much difference for me in other aspects. In other words, U30 is like another version of U20. I really appreciate the new 3D printer, it has a smaller build volume, but with advantageous features, including the color touch screen and useful resume functions. The printing quality is as the same as that of U20 with the same motor, motherboard, cooling fan, extruder...I believe U30 is much better than all its competitors and I've already recommended it to all my friends interested in 3D printing.

    Amazing performance, low price, and good service
    The videos are helpful for me to know the product. I've already seen some people discuss the new printer on the supportive Facebook group of Alfawise 3D printers. My first impression about Alfawise U30 is that the 3D printer is attractive, easy to build, and of excellent quality, and convenient to use. It does not disappoint me at all. I use Alfawise U20 when I need to print big models, and use Alfawise U30 when small ones are needed. The latter works as well as the former, and they are of the same quality, both are great! I am sure it will be more popular than Alfawise U20, because of the price. However, the main difference between the two printers is that a man cannot assemble U30 in about 10 minutes. I managed to do it within an hour, which is great.

    Mon bon assistant, cette imprimante 3D de qualité!
    J'ai souvent besoin de l'impression 3D dans ma vie. J'ai appris par des amis que l'imprimante d'Alfawise était bonne, j'en ai commandé un en ligne. Permettez-moi de parler de ma première impression de cette imprimante 3D: son apparence est très simple, sa couleur me convient parfaitement, elle a l’air très solide et doit pouvoir être utilisée longtemps. De plus, j'ai trouvé que cette imprimante était très facile à installer, et il m'a fallu moins d'une heure pour l'installer. En ce qui concerne l'opération, je me sens très bien à utiliser. J'ai essayé d'imprimer une petite fleur et le résultat était très bon. Mes enfants l'aiment beaucoup. Il semble que je n'ai pas à m'inquiéter du travail manuel des enfants à l'avenir. En un mot, j'aime beaucoup cette imprimante et la recommande à tout le monde!

    Alfawise U30 is to be another best-selling 3D printer
    It is wonderful to get Alfawise U30 at the end of 2018. Although the printer cannot build as big as U20, it has all the features I want, and I am satisfied with the precision printing, 0.1mm layer with 0.4mm nozzle. The touchscreen can be installed on the left side, which is great! I can operate it with my left hand. Indeed, more convenient for the left-handed! I really like the user interface, silky operation, and want to have the touchscreen on other printers! By the way, the firmware is on the TF card that comes with Alfawise U30.

    Daumen hoch! :)
    Die Lieferung des Alfawise U30 ging sehr schnell von statten. Der Aufbau selbst ist sehr leicht und machte keine Probleme. Das Leveln des Hotbed ist auch sehr angenehm und ging auch recht zügig dahin. Ich habe die ganze Prozedur 5x gemacht, um ein sauberes Ergebnis zu erzielen.Was mir sehr gefällt ist auch die Filament Halterung. Das Touch Panel ist sehr gut zu bedienen und reagiert wunderbar auf die Eingaben. Aktuell drucke ich mit PLA und experimentiere noch etwas mit den Einstellungen. erster Testdruck waren die Testeulen :P die sehr schön geworden sind.Prinzipiell habe ich nichts auszusetzen. Ich bin vollkommen zufrieden mit dem Gerät. Daumen hoch! :)

    For the science class
    3D printing is hot in every school, and children are very interested in it. Alfawise U30 allows them to learn everything from scratch, how to build, model, set the parameter, print... The size is smaller, but it is perfect for the desk. It is more budget-friendly, so we’re planning to buy more, so everyone has the same opportunity to learn better. The technical support on Facebook is soooooo great! I hope my students will ask more questions about it and improve their skills.

FAQ for Alfawise U30 2.8 inch Touch Screen DIY Desktop 3D Printer

  • Where to download the firmware of Alfawise U30 DIY 3D Printer?

  • How to update the firmware of Alfawise U30 DIY 3D Printer?

    1. Copy firmware to the SD card;

    2. Then restart the machine and wait for the machine progress bar to complete before the firmware is refreshed.

    3. Then the user needs to delete firmware in the SD card to be used normally, otherwise the firmware will be refreshed every time the printer is turned on.

  • What if the filament does not discharge from the machine?

    1. After the machine nozzle is heated, the consumables are normally fed into the feeding mechanism by hand, and then passed through the Teflon tube to enter the nozzle.

    2. When it is found that the gear of the feeding mechanism emits a "beep" sound, it can first check whether the consumables are wound, causing the extrusion mechanism to pull the material.

    3 If this is not the reason, raise the machine nozzle and use the 0.4mm needle in the toolbox to insert it from below the copper nozzle and rotate while inserting.

    4. Under normal circumstances, this needle can be used to open the copper nozzle, so that the feed is smooth. The reason for this blocking is generally that there are impurities in the consumables, which leads to plugging.

  • When the machine returns the filament, it can't be returned. What should I do when stuck in the pneumatic joint?

    1. Before returning the material, please heat the nozzle first, and then withdraw the consumables as soon as possible. If you can't pump it, you can re-feed the material with the advanced material, and melt the extruded block formed at the end of the consumable in the nozzle.

    2. When withdrawing the consumables, before the end of the consumables reaches the pneumatic joint, we will usually pull the Teflon directly from the Teflon and cut the end of the consumables.

    3. Because the end of the consumables in the nozzle will be deformed by heat, if the end deformed consumables are directly pulled out, it may be stuck to the pneumatic joint or the limit switch for damage detection. (The limit switch for the broken material detection is single Towards).

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

    If the power is suddenly turned off when the part is first printed, the machine will not save the print data. Unless the height of the print exceeds 0.5mm, the power failure will be supported. If the height is less than 0.5mm, it is recommended to reprint directly.
  • When the machine is leveling, the nozzle moves to the left, it can be leveled normally. When the nozzle moves to the right, it is found that the distance between the nozzle and the heated bed are very far or very close. If the spring is adjusted to the extreme position, it still cannot be leveled.What should I do?

    If this happens, the X-axis beam is generally loose. At this time, the hex socket on the right side of the machine can be adjusted with a wrench to adjust the tightness.
  • After the machine heats up, the filament is discharged normally. However, when the printing is performed for the first time, the curling occurs on the platform. After printing several layers, the filaments get out of the platform. What can I do?

    1. After the user gets the 3D printer, if the leveling is found to be curled on the first layer of silk, it feels like it is gently falling on the platform. It can be judged that the leveling is not adjusted, and the nozzle is too high from the hot bed.

    2. At this point we need to re-level, the quality of the leveling can largely determine the success rate of the part printing.

    3. In addition, in order to ensure good contact between the model and the platform, we can set the larger plane of the model face down when slicing, and can also be set in the slicing software to add Raft to the model, which can make the model stick to the platform firm.

  • How to using Cura 3D slicing software?

  • Why not extruding at start of print?

    1. Extruder was not primed before beginning the print;

    2. Nozzle starts too close to the bed;

    3. The filament has stripped against the drive gear;

    4. The extruder is clogged.

  • Why not extruding enough plastic?

    1. Incorrect filament diameter;

    2. Increase the extrusion multiplier.

  • why there are holes and gaps in the top layers?

    1. Not enough top solid layers;

    2. Infill percentage is too low;

    3. Under extrusion.

  • Why the 3D printer always overheating?

    1. Insufficient cooling;

    2. Printing at too high of a temperature;

    3. Printing too fast;

    4. Try printing multiple parts at once.
