M Prime One

simple, affordable 3D printer for makers

What is the M Prime One?

a simple and capable 3D printer

designed to be simple

Designed from scratch to be a simple 3D printer with few parts. Easier to assemble, easier to maintain and more affordable.

autoleveling system

Our M Prime One includes an autoleveling sensor in the printer head that corrects the printing surface inclination. No more manual bed adjusting before each print!

You can also take out the magnetic printing surface to easily remove printed parts and the sensor will recognize the position of the bed when you put it back.

high quality extrusion

The extrusion system is one of the most critical parts of your printer. We have chosen an E3D lite6 hotend and an all metal PTSone extruder for the M Prime One, original components designed and manufactured in Europe included by default in a budget 3D printer!

size and portability

The M Prime One is a compact, desktop 3D printer with a printing volume (20x15x15cm) that will let you print a wide variety of 3D models.

We have also integrated a handle in the printer frame, so you can carry the printer with you when you need it.

perfect for makers

build your own 3D printer

The M Prime One is a 3D printer for makers, sold in a kit with all the components and accompanied with online manuals to guide you through the complete process.

Enjoy the experience of building your own 3D printer and learn all about how your machine works.

choose your colors

Customize your kit by choosing your frame and printed parts colors. There are 8 possible combinations.

ready electronics

The 3D printer electronics are already assembled, loaded with the printer firmware and the motor drivers calibrated. Just put the board in your printer and connect the cables.

no soldering

All the kit cables are cut to length and fitted with connectors, no soldering is required to build the printer.

a hackable 3D printer

open source

Our philosophy is building completely open 3D printers that the community can build and improve.

We have not only published all the printer files and manuals in Github, but we have developed our products with open source software, so you can download and modify the files for free.

customize it

Being open source and supported by a great community, our printer is constantly hacked and customized by our users.

Check the mods that have already been uploaded to Thingiverse or download the source files and start creating your own custom parts.

with great support

build manuals

We have created manuals for all the steps in the assembly and setup of the M Prime One. They are public and accesible to anyone, so you can check them in our webpage:

any question?

You may have questions during the building process. No problem! Our team and community will help you get your printer up and running with our Google Plus community, support forum and email support.
