Welcome to the Metalbot Project Portal. Here you can access our current development of the main sub-systems that go into the printer. We want the design guide to follow the most practical route for hobbyists and enthusiasts to make their very own 3D Metal printer. Have a look at our wiki map for a birds eye view of the project. To learn how to use this site please look at our website user guide.

To navigate this wiki please use the menu sidebar which can be accessed by clicking the top far-left menu item.


NOTE: At this point in time there is no official 'Metalbot' design guide. We are still in phase one of the project: building up a knowledge base. Beta designs can be found below and the official design guide will fill up with key information from the portals below.

Want to help with development? Get in touch with us at info at metalbot dot org or introduce yourself on the forums and tell us where you envision the project to going. Feel free to lurk around for a while to get a feel for the project, then participate!


Current Progress

We are currently in the first phase of the Metalbot Project, which means that we do not have a functioning prototype yet, however we are working exceptionally hard to release the design files for the worlds first open source 3D Metal Printer.

As an open source project, we need your help. Most of the sub-systems have been developed already for different purposes. Our job is to put them together into a compact and modular design that is user friendly and works. ​​There are many challenges to be faced between now and a releasing the design files for a working model. Each sub-system linked to below has it's own goals and challenges and as the project develops issues and requirements will become more specific.

Visit the following subsystem portals for more information on progress and development...


Sub-system Portals

Metal Consolidation

This category deals with joining or fusing layers of metal together. There are a number of consolidation techniques that can be used for example lasers, arc welders, electrochemical processes etc... visit the metal consolidation forum for more discussions.

Software and Electronics

From powering inverters and laser power supplies to controlling powder pistons and wire-feeds, the software and electronics that go into the Metalbot are a major technical feat. More discussions can be found on the software and electronics forum.

Software & Electronics Portal


Hardware and Frame Design

There are a number of different ways to handle materials in the printer, e.g. powder spreading or wire feeds. Find out more on the hardware and frame design forums.

Cost Planning

In order for the printer to be truly accessible we need to keep the bill of materials affordable. For more talk on the Metalbot budget head over to the cost planning forum.

We want to set a high standard for Open Source 3D Metal Printing. This means data. The more we know the better design choices we can make. ​If you would like to join the Development please contact an administrator or say so on the forums. You can then add your experiments and data to the wiki.
