Re: New project powder 3D printer ZEUS

Hi myying,

a bit late response, sorry. These kinds of spreading issues are quite common even on the Projet 660. They are usually due to dirty spreader roller / scraping blade, or more often because of worn out powder (i.e. some of the finer granules have gone after many print works)

cheers

Re: New project powder 3D printer ZEUS

About powders I can't help much. I'm still experimenting, but still stuck with the official 3DSystems powder. This is perfect powder but difficult to procure and costs reaaaally a lot (like 1000€ the 14Kg box) My main problem is that alternative powders, even if they print well, would clog the print...

Re: New project powder 3D printer ZEUS

Hi MaxT hmm, I did not think about it, although it is logical, I did not do this before. yes i will resize I think maybe 300x200x200 I’ll make the piston a little bit with a margin; no need to completely fill the piston when it is not needed Hi Masic, that's 12 Liters / 30 Kilos, much more reasonab...

Re: New project powder 3D printer ZEUS

Hi Masic, saw your posts few days ago but didn't have time to comment any sooner. You may want to think again about the desired printing volume. You plan 30x30x30 cm. That makes 27 Liters, filling it with gypsum powder will make 67 Kilograms (roughly 2.5 Kg per Liter) !! That's too much weight. How ...

Re: Hacking the HP45

Hello Inkjet you posted photos about lot's of interesting boards. However you hid the information necessary to search for more info about these boards. This is fair, if you can't share these info, however the photos themselves are not useful to us, unless you explain better what function they do and...

Re: Generic powder machine controller

Hi david, the 3DS printer accepts only vrml and ply files, but only because their slicer is quite old software (but very fast anyway). There is no significant difference between the 3D formats. You can generally convert them back and forth without loosing any information. So you can choose whatever ...

Re: Generic powder machine controller

Hi wonko. thank you for the link to your slicer. I already had a brief look at it in the past, I had dismissed it too quickly because I thought that, by voxelising, it was able only to handle face/vertex colors and not textures.

I'll look again how you approach this issue, thanks

Re: Generic powder machine controller

Colour slicing is a bit complicated, simply because there are not many public available examples. The initial test of my printer will be based on single colour or manually set colour. Later development, in my option, will tweak a VRML reader and add a slicing function, for example, using the VTK pa...

Re: Generic powder machine controller

Hi david, this sounds really great! let's see how the epson head performs, you'll probably need to make some experiments to find the right glue density to prevent clogs. One question about the slicing: how do you do it ? Last few months I've spent some time analysing possible implementations of a sl...
