this time the machine is very large, but seeing this I imagine a bit more: http://www.dailymotion.com/video/x7fk8n ... briqu_tech


It's superb but .... but in this case it will give some ideas to find a source of savings ... by removing a max of employment .... : Cry: :|

Thank you Pascal for these details,

It looks really interesting your neighbor's machine. You don't seem to be talking about a digital model. However, this step seems essential to me. In general this opens the options to scan or draw. Can this printer be powered by 3D drawing software?

See you

Yves

I am also very interested in 3D printers, I am actually building one working on the same principle as reprap (using plastic wire that is melted as in a glue gun).

But where reprap can only do 3D printing, my machine is rigid enough to mill small plastic parts.

I build it with the maximum of parts from the recovery of old printers and scanners.

For now I am improving the precision, then I could mill the extruder (the 3D print head). I also hope to be able to mill electronic circuits directly.

Everything works under Linux with EMC2 software:

On the same forum, there is also a high resolution 3d printer project made from a video projector:

Hi petrus

It is very beautiful work that you present us there, a lot of time surely but exciting. I will follow the rest carefully. Thanks for the links.

Petrus, I am amazed by your work!

It's awesome.

I can't wait to see what you will do with this machine, the precision you will be able to achieve, the ability to print several pieces in one pass ...

We are still far from the reprap (the one that turned me on the subject): it's infinitely better right?

See you

Yves

The operating principle will be the same as on the reprap, so the print quality will be the same.
Example of what we can do with a machine of the same type, here a makerbot:
http://www.thingiverse.com/thing:7930

But since I make everything myself, I could do some experimentation to increase precision, such as making a finer nozzle, a repraper has already made one of 0,18mm, the standard being 0,35mm:

Thank you Petrus for this information and for the sites you indicate. I see that these self-made machines do not have much secret for you.

Do you know if there are "easy to access" technologies other than the nozzle that would allow better precision? Even if you pay a little more ...

Do you think that waiting a little (1 or 2 years max) will allow significant improvements in current technologies?

thanks again

For the moment, the melted filament technique is the only one that is fairly inexpensive.

For "plug and print" machines there is the up printer:
http://up3d-printer.fr/
But it is not open-source.

The principle of the 3D printer made from a video projector is very promising in terms of resolution, the biggest problem is where to find the right photosensitive resin at an affordable price.

Already the closest seller for reprap plastic wire is in Germany.

Certainly Petrus, you know this subject perfectly.

Very interesting this model. But the definition announced does not seem better than the one you already told us by reducing the nozzle of the reprap. And reprap is still a lot cheaper.

Another point that interests me a lot is the software that controls printing. Personally I work with Open Source Blender 3D (which has just published a completely new version with a very professional interface). This software allows you to export to the various universally recognized formats in this field. Is that enough? can we have any surprises at this level?

Thanks again,

Yves

At the moment there is no affordable high resolution printer for an individual.

No problem with blender, you just need software capable of exporting the object to .stl, blender does it very well.
For the moment, I have not looked too much at the software, I just started a tutorial to use blender.

You also need software to convert the .stl file into code that can be understood by reprap (gcode). There are several, but from what I read about forums, the best is Skeinforge, it is very complete with a lot of adjustable parameters.
