There are many hazards when dealing with the high wattage lasers necessary for sintering. Please read here for a full briefing on laser safety: LASER SAFETY

The most obvious danger associated with lasers is getting the beam in your eyes, therefore:

Always wear safety goggles when dealing with lasers. The beams are infrared and invisible to human eyes, but can instantly blind you forever.

And not a cheap set of goggles either, your eyesight is worth more than $20. Go for a higher quality pair. An infrared laser beam is completely invisible and can deflect off of almost anything.

Other dangers include dealing with power supply hazards and components that get very hot.

Safety

Dealing with high power lasers (10W<
​Working with potentially toxic metal powders
Proper ventilation

Dealing with ventilation of inert gasses.​
Dealing with the health hazards of metal powders.

Terminology

Jump to: navigation, search

Welcome to the terminology page. This page is useful for keeping consistent documentation. As with most of the pages on this wiki it is always improving and always under construction.

It is important that the terms we use convey the general function of what the term describes...

To submit a term either post it in the forum here: suggest a term or directly edit this page (you need to log in to do so).

When submitting a term please add it to the appropriate subheading and in the following format:

=== Term ===

The text describing what the term refers to

 

Contents

Hardware Terms

"Powder Spreader"

The mechanism that pushes the powder across the build platform.

"Build Platform"

The flat sheet, either made of ceramic of metal, that moves down in very small increments.

"Laser Scanner"

The method of moving a laser beam in X-Y coordinates.

Scope of the project

How it's organized

How can I contribute?

We are always happy to see new faces here! There are many ways you can get involved... please have a look

at the goals page to see exactly what needs development. Get started right away by joining the Metalbot forum and

wiki to start contributing your ideas... ​​

In addition to development there are many ways which you can show support such as helping with documentation,

forum management, making suggestions and telling other people about us!

 

Sourcing Materials

If you have found a place to source materials (e.g. titanium powders) please add it to the Materials MEGA Index here: viewtopic$%

This greatly helps toward our eventual bill of materials

Overview

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.

Metal Consolidation Portal

 

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.

Hardware & Frame Portal

 

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.

Cost Planning Portal

Development Goals

Please note that the goals below are not final design specifications but rather 'ideals' that we would like to try and reach. As we do more tests and receive more data the design goals will be adjusted to suit the needs of users.

Ideal Printing Material Titanium Pending Community Approval
Material Form Powder Pending Community Approval
Target Resolution <100um Pending Community Approval
Target Part Density More Data Required  
Build Area 150mm2 Pending Community Approval
Build Volume ?mm3 Pending Community Approval

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.
