Many thanks to all my backers, who allowed Zatsit to be born!

Please excuse the somewhat chauvinistic enthusiasm of my compatriot Frederic: it is not French "en plus", it is just French. The French are considered pretentious all over the world, so there's no need to add to that!

Joking aside, thanks to Tony for drawing attention to Zatsit, and thanks also, of course, to my distinguished backers!

In this forum, you are all supposed to already have a 3D printer with a Duet controller on it. So let me also talk about accessories, which can be adapted to all existing machines, especially deltas.

Thanks to the engraved Hylite technology, it is very easy to make gimballed supports for remote accessories (extruder, blower fan). This has significant consequences on print quality, as the effectors can be lighter, parasitic forces on them are reduced, and the length of the Bowden tube can be halved. These brackets attach to any 6mm T-slot, so they are universally applicable. Here is a video that explains it.

The gimballed support for a Flystruder based on Titan extruder, adapts to absolutely any delta machine, with even more obvious improvements: the Bowden tube is reduced to 17cm, while disturbing as little as possible the movements of the Hot-End. Here is the video.

Finally, one of Zatsit's major innovations is its Hot-End, so simple that you won't believe it! Here is the video.

I first wanted to obtain a larger exchange chamber with cooling water, with many unnecessary complications, before realizing that it worked strictly as well with a simple 4/6mm tube, pierced! Since I have been using a pre-hole formed with a very precise biopsy punch, the seal is extremely reliable. And in two years, the Hot End has never jammed, with any filament. Never! The only problem I had was stupidly pulling a very hot TPU filament by hand, which obviously immediately stuck to the cold zone.

Since I have to put some coal in the boiler, let me to provide the link toward Kickstarter (with many interesting info, anyway). Thanks for watching!

Just after the end of the KS campaign, two new pages will appear on my website www.zatsit.fr : STORE and DOWNLOADS.

You will be able to download the configurations for the different systems I was able to try, including of course Duet WiFi.

I am considering a similar project, for a CNC specialized in the machining of Hylite composite plates, including both milling cutters and saw cutters.
I need 5 Z axes carried by the same Y slide. I think I will limit the Z stroke to about ten mm, and I hope to keep the moving masses reasonable.
I think I can handle all this with MachineKit, unless the Duet 3 option comes up fast enough: my project is not immediate.

This filament containing nanodiamonds does not wear out the nozzles, because firstly these particles are practically round, and secondly their size is homogeneous around 10 nanometers (supplier's data).

@deckingman
I would like to draw your attention to a very special PLA filament, whose thermal properties have been modified with diamond nanoparticles, Carbodeon's uDiamond. This filament doubles, at least, the extrusion rate for a given hot-end/nozzle.

I experienced this during mechanical speed tests (and not extrusion flow test), to check the behaviour of my Zatsit hinged delta at high speed, with regard to ringing, and the speed/print quality ratio.

The hot-end I use usually delivers, with a standard 0.4mm nozzle, about 8mm3/s. With the uDiamond PLA, the throughput exceeded 15mm3/s, which allowed the printer to be tested at up to 560mm/s, with standard Hot-End and nozzle.

This shows the huge influence of the filament itself, for questions of extrusion throughput.

Yes, this small stainless steel tube, thus cooled, opens up a whole bunch of possibilities, which I am currently developing, and which I hope to be able to offer after Kickstarter.

1 - The volume of the Hot End can be divided by 5, and the weight reduced by 3, by directly integrating a miniature nozzle at the bottom of the tube. It is the tube+nozzle assembly that would become interchangeable, rather than the nozzle only.

2 - These miniaturized hot-ends make it possible to have a very light extrusion head, of the Direct/remote type, with two or four independent extrusion channels, but with a single drive motor, in the Flystruder position. I have already made a single-track version, which works extremely well.

Delta printers have great qualities, but they were generally limited by their single-channel Bowden tube. With 4 printable materials, you can imagine the possibilities!

@deckingman
Yes, of course.

@deckingman said in Zatsit printer:

could you supply shorted lengths of this tube

Probably.... What do you have in mind?

@deckingman
Yes, all accessories, including this adapter for Hot-end watercooling, are available independently of the Zatsit kit, during the campaign on Kickstarter, and then on the online shop that will follow.

Take a look at the Kickstarter page, it says it all!

To manufacture this adapter, I use a specially modified small lathe with a special saw to cut the tube straight, and without blurr.

@fma
You're right : 350°C, not 400°C. It doesn't change my conclusion.
