New printer in construction – Voron 2.1

6 Replies


First of all, I wish you a happy Christmas. Today I start a new series of post about the new printer that I am building right now,  Voron 2.1.

Features of Voron 2.1

  • It is a Core XY printer with fixed bed plate, I like that because the movement of the bed plate is one of the things that worried me on the cartesian printers.
  • 2020 aluminium extrusion profile, so is cheaper than other similar options.
  • It has 4 independient motors for Z axis, so it will adjust very precisely.
  • It is a closed printer with a carbon filter, so you can print ABS without problems.
  • The dimensions of the printer are relatively small, it is a cube of  50 cm,  for a bed plate of 350×350 mm
  • It use linear guides and belts.

Material needed for the build of the Voron

In the printer´s page you can find a configurator based on the size that you want for your printer, below you can find some screenshots:

Choose the frame joints

Estructura Voron

I have choose Openbuild option because I cannot buy on misumi, because the only sell to corporate clients.

Choose bed size

Cama Caliente Voron

I get 350mm size, because I want to print helmets in one piece.

Get the result and download the BOM

You can download BOM(Bill Of Materials) on a csv file, in a few day I will write about where to get all the materials needed.

Voron printed parts

There are a huge amount of pieces to get printed, in the communitiy people said that must be printed on ABS (at least the parts that are inside the chamber).

I have printed them on PLA Ingeo 870, because the behavior is similar to ABS and is not topxic when you print it.

You can find the parts that you must print on the following link.

Build Manual

You can find here a complete manual to build your printer.


Due to the brilliant design and features, this printer has a huge community, you can find a lot of help here:

    nice project! Very good discription, especially the thing about the printed parts with PLA instead of using ABS. I am thinking to start the same building but in the 300×300 size and i have the same problem with Misumi ( I am from Germany). I have the option of 2 profile types in 20×20. The one has a 5mm slot (Item Profil) and the other has a 6mm slot (Bosch Rexroth). By using the Bosch Profile i have to use M6 instead of M5 at the corners but this will not be a proble, but they have something like a little edge on the slots, the Item Profil look similar to Misumi but they have the smaller slot, here is my problem, which one should I take? Will this be a problem with the Bosch Profile? Which one did you use? Another question, will the area of 120×120 be enough to print the parts?

    Thank you for your support! Greetings from Germany!!!

      Hi Georg,

      I bought the profiles on Germany at motedis ( I have bought B type profile with 6mm slot. The problem with these profile is that you must mechanize them (you can order them mechanized, but the price is 1€ per hole, and it is very expensive). The mechanized holes on the profile are made for M6 screws. And I have used corner cubes to join all the profiles, with the exception of the profiles that are the base for the bed.

      I think that 120 x 120 printing area is not enough for some pieces, 120 mm fan cover, some bottom skirts, I suggest you to buy some pieces that you cannot print due to your printing area. I think you can print 80 % of the pieces with 120 x 120 mm printing area.

      I have printed the parts on an Anet E-10 with a printing area of 220 x 270 mm, and I has some problems with some bottom skirts.

      Than you for your support, and if you have any othe doubt fell free to ask. 🙂

    I’m very glad to have found this nice 3d printer project.
    Excellent description and implementation guide.Professional work.
    I have long dreamed of a Core XY printer with a fixed bed plate.
    I have made Delta, Prussia and HyperCube Core XY printers and I have
    the necessary experience in building them.
    A am thinking to start this project but in the 250×250 size.
    I have problem with financial resources and
    is it possible to reconstruct some parts and axis Z
    be placed on linear rods 8-10 mm. and linear bearings?
    Axis Y and X remain so.
    Thank you for your support!

      I think that the original project is very good, and they ate goingover to release a new version in a few days.

      I think that one of the best things is z axis, and if you buy linear guides on China the expenses are not being high. More or less 15€ per guide.

    As a long time Motedis Customer and also being from Austria they’re the only option.

    Did you have to redesign anything for using the Bosch profiles? I have tons of Item stuff here, but I really don’t want to redesign about every part, so Bosch would probably be the only viable option..?

    1. Mr. Appz Post author

      First of all, sorry for the delay on answering you.

      I don´t need to redesign any part using the motedis B profiles, only the lenght of the profiles in order to take in consideration the assembly cubes por each corner 🙂

      Thank you for writing me.
