The Crane Bowden is a high quality, yet affordable, easy to use 3D printer which has a Duet 2 Maestro control board, one of the best open source boards available. The Duet 2 Maestro allows you to create higher quality prints, and have faster responsiveness and less noise due to the fast Arm processor combined with RepRap Firmware and trinamic drivers. It comes fully assembled, with a heated bed, LCD control, and SD card slot so you can print without needing a computer. The Bowden style feed and brass 0.4mm nozzle allow you to create detailed prints quickly.



The Crane series of 3D printers was only made possible by having a strong base... and that's the Crane Bowden. It's a 3D printer that is easy to use, prints beautifully and is a reliable work horse. 


For those just getting started with 3D printing and are looking for an approachable open source 3D printer, the Crane Bowden is for you. Coming fully assembled means you can use it right out of the box and without fear of faulty installation a couple hours of assembly that normally comes with these types of printers. As an open source printer, rest assured there is a huge community behind it, in addition to M3D's own passionate community, with lots of ideas, support and troubleshooting material to guide you through 3D printing.


Further, as part of the larger Crane series, Crane Bowden users can easily update their printers to a direct drive system for printing flexible filaments, in addition to the Dual and Quad multi-filament setups with readily available parts. 




The production philosophy for the Crane represents a new generational strategy for M3D as we’ve honed our value as an integrator, innovator, assembler, and quality control checkpoint in the USA.  Our goal is to combine the value of highly affordable printers with the reliability and innovation typically seen at much higher prices so that users can do more with less and even operate fleet of printers that they can count on...  


M3D is doing this by combining recent strategies used by low-cost manufacturers, expert innovators, and community contributors.  Low cost manufacturers leverage proven designs and high-volumes to offer great value, but they can miss the mark on customer service and quality control, leaving buyers with a bit of a gamble.  On the other hand, innovators invest in R&D which leads to innovations that enable users but are often proprietary and expensive, which usually restricts the users freedom. Finally, open-source and community contributors often develop products with real value, but manufacturers tend to take rather than nurture these independent innovators.  By integrating all three we’ve realized a product that is standard in its approach and easy to modify, while also providing the most competitive foundation on which several innovative options can be added.


Simply put, many companies try to pair their innovations with excessive changes.  We’re taking the things that work well in our industry so that our innovations can shine.  We’re one of only a handful of companies to take on color 3D printing and the first to do so under $500.



To help customize your Crane to better fit your needs, below is a sample of add-ons we plan to make available during the check out process: 

  • Direct drive adapter
  • Extruder expansion board
  • Infrared bed leveling sensor with LED
  • Hot section
  • Motors
  • Fans
  • Nozzles
  • Filaments


You can use any standard 1.75mm filament in the QuadFusion Print Head, however if the colors aren’t optimized for color mixing, you may not get a high quality color result, for example if you want to use a key like Black, you need to use a calibrated black because typical black filaments are loaded with carbon pigments which have a very wide particle size and distribution, so what would normally happen is you’re trying to change from black to yellow for example, and you’re going to have to expunge 200mm of filament to get a clear switch between the two, which is a very large waste pillar, and even then you still may have residual specks of black show up in your print.  


To solve this problem we developed a few lines of filament that would be ideal for color mixing. To do this we calibrated the pigment size and molecular distribution so that it falls within a narrow range, giving you the ability to get controlled mixing ratios, which results in a wider and more pure color palette. The recommended starting material is based primarily on PETG, which comes in two series: ABS-R3 provides opaque material ABSR provides transparent colors and keys.  We also offer an opaque PLA line, as well as an opaque Tough 115A line.  



We feel it's necessary to be as forthcoming as possible: multi-color printing is experimental. We have made progress in printing gradient and spot-color prints in recent weeks which is encouraging. We ask that all Crane Quad supporters recognize that this is the beginning of a larger color movement; one in which we plan to be an active coach and mentor. As always, we'll have daily conversations in Discord with those wishing to contribute to the color 3D printing movement and will be posting updates, files and all information to GitHub. 


The following are examples of what we plan to tackle as an open source community together:

  • File formats being made specifically for color printing
  • Slicing such files
  • Calibrating various filament colors and types
  • Exploring different filament types and their mixing relationships

This is a journey, not a race. In making the Crane Quad available at an affordable price, it is our goal that more people will be able to join us as we create a whole new way for consumers to 3D print.



  • Product prices are dependent on when you want to receive the printer. Per our current timeline, Batch 1 shipments are planned to begin in August. 
  • Like all 3D printers from M3D, the Crane is designed, assembled and supported in the United States.
  • Shipping fees will be calculated as shipping times approach and any add-ons are added to the order. VAT will need to be paid to the carrier at the time of delivery.
  • With every purchase, a portion of the sales will go back to Duet3D to support the development of Duet hardware and RepRapFirmware (RRF).
  • All Crane 3D printers come with a six-month warranty



It's been quite a ride since our company sold its first printer four years ago. Since then we've been able to innovate new 3D printing solutions and we're excited to expand our offering with these printers. We're a small, passionate team with big dreams and we're truly grateful for your support!
