Prusa i3 3D printerPrusa i3 (i3 stands for third iteration of the design) is the latest design by me. There are countless variations of the design and it became a staple of 3D printing with tens, if not hundreds, of thousands units world wide. You can build simple one for couple hundred dollars or you can chip in more and get the state of the art 3D printer, it’s all up to you.

It’s open functional design allows for quick maintenance. For example if our DumbExtruder™ (LOL) breaks you can clean it in couple seconds! This makes i3 great workhorse 3D printer for your business. Not to mention the ability to upgrade the printer as you wish without manufacturer forcing you to buy a new model! Future-proof FTW!

The printer is constantly under development. In the latest revision of the original version I switched the default extruder to E3D hotend. Read more about this latest update here. I also made it super easy to do color 3D prints based on the layer height. You can check out color 3D printing here or watch the video below!

P3D_Printing_Trends_May_2015___3D_Hubsrusa i3 became more popular than was ever anticipated. According to 3DHubs i3 is the #1 3D printer on the planet. The popularity led to hundreds of forks and the numbers are still growing 🙂

The best part is, as the community grows more people can share their tips and tricks. Also finding help is always easy online 🙂

  1. Quisiera saber donde puedo conseguir los planos del marco para construirme una Prusa 3 i
    en acrilico o en acero soy de Montevideo – Uruguay, aqui no he conseguido marcos hechos y traerlos del exterior se me encarecen mucho si consigo el croquis en archivo STL, lo puedo mandar a plotear en acrilico o a cortar en acero por laser.

    Espero respuesta gracias.

    • Hola amigo yo tengo esos planos si te sirven mandame tu correo, yo hice una prusa en acrilico 5mm.

  2. Does it need to be used with a 3mm filament? In my country (Chile) its hard to get, and it’ll be a lot easier if i can install the regular 1.75mm filament.

  3. where are the stl files located for Prusa I3 1.75mm high quality printer?
    love this machine but I have to print parts to fix it

  4. 2 thngs: Would it be possible to swap out the extruder nozzle with a custom made blu ray for laser cutting etc? And, please make said item and take my money.

  5. Received my i3 kit Thursday. Very nice quality, impressive build manual, though I preferred the on line version with bigger writing! Y belt was a bit too short but everything else excellent. Got a new belt locally so it was printing straight away. The settings for Slic3r are spot on, great prints! The kids love it too, queuing up with things to print! Thank you for sparing me the frustration usually associated with setting up a 3D printer.

  6. So, I’m 90% sold on the Prusa i3 as my first 3d printer. I am curious about how the quality of the individual parts effects the price. There are other “Prusa” model printers out there for half the price. What makes this a better printer than other Prusa based repraps? Is there a noticeable difference in the print quality of a cheaper reprap vs the Prusa i3?

    • It is easy, the others don’t have knock off electronics (often removing safety/over temp/ high current parts replacing them with nothing or lower rated parts), they don’t actually Innovate, they just copy (this is the company that started the i3 design), a genuine e3d (E3d knows more about melting plastics than any hot end maker, every machining step has a purpose, the knock offs skip steps), the mechanical parts are made with care ( you can buy cheap kits that fall apart), and automatic bed leveling (a god send)

  7. Where can I get the firmware to change hot end max temperature to at list 275C?
    I can’t get satisfying quality with printing ABS at 255C and on 260C I get an error.
    What is the allowed max temperature for hot end (I’ve got an official prusa i3 kit 2 month ago)
    Best regards
