QuoteAny news on bringing this promising extruder to market? I'm working on it, but most of my time goes to completing the deliveries of the delta Zatsit printer for my Kickstarter Backers. The first prototype I showed in this post evolved into a multi-material extruder concept (2, 4, 6...), with a single stepper motor, and a single electronic driver, for the 2xn channels. The basic idea is theby M_Xeno - General
Quotea lot of air flow, which is what we need for cooling I don't think so. If you want to quickly freeze the filament that has just been deposited, for example to improve details or do bridging, you have to remove its thermal energy as quickly as possible, and since the exposed surface for this heat exchange is very small, you can only rely on one thing: the speed of the air passing on this miby M_Xeno - Reprappers
Nice implementation of this idea, which I am very happy to see taken up again! Be careful, however, to increase the surface area of exchange with the outside. In my example for Zatsit, the hot chamber was very flat, disc-shaped, and moreover, relatively well insulated upwards, by foam cardboard. Geometrically, the area through which losses occur was minimal. In addition, in a flat chamber a fewby M_Xeno - General
@NforcerOH No, no! Dibond is not at all the same as Hylite! Dibond, Alucobond and others have a Polyethylene (PE) core. The core of the Hylite is made of Polypropylene (PP). Only PP has the molecular structure to make them durable hinges.by M_Xeno - Reprappers
It's strange to see simple ideas stack up in such a complex way! K.I.S.S! Here is a really KISS solution: Water-Cooled Hot-End www.zatsit.frby M_Xeno - General
QuoteMKSA Here you have the complexity without this advantage. Indeed, unless you consider that, in the provided drawing, the motors are still fixed, and that it is the whole belt and pulley system that moves (and remains lighter than the motors). Then, you have the benefit of shorting belts...by M_Xeno - General New Machines Topics
I am in the production phase of my Zatsit delta printer, and I would like to share my experience with extruded aluminium profiles. While remaining perfectly within standards, the extruded profiles that can be purchased at retail may have curvatures or twists that are actually incompatible with linear, direct or indirect guidance applications. The profiles are extruded in long lengths, then cutby M_Xeno - Extruded Aluminum Frames
End-inserted T-nuts for 6mm slots from MISUMI are both cheap and very suitable, with M3, M4 and M5 versions. Sold in 100pcs bags.by M_Xeno - Reprappers
www.zatsit.fr Combining carbon rods with Hylite hinges is a false good idea: the fastening to assemble the two technologies will result in the loss of the major advantage of dimensional accuracy, which, in Zatsit, results from the fact that all critical dimensions are defined at once, by CNC cutting, with its accuracy. I encourage experiments in Hylite, but if it's to make a 3D delta printer wiby M_Xeno - Reprappers

Hi Shadowphile ! I don't know if Hylite is even distributed in U.S., and I think there is no competitive products with PP core. Hylite is distributed in Europe by 3A Composites. For small cut-to-size panels, you can ask www.modulor.de, in Berlin. I'm very interested by what you want to do with it !by M_Xeno - Reprappers
In an attempt to improve the warm-up time, I tried various insulation configurations: fixed, under the bed, and removable, above. These efforts have been very disappointing. I understood when the bed is cold, most of the energy you supply it is used to heat the thermal mass it represents. Convection losses to ambient air are completely negligible in front of this mass heat to be supplied. In adby M_Xeno - Delta Machines
@o_lampe Yes, I am sorry to have announced a deadline that did not take into account possible hazards that have occurred. But don't worry, Zatsit's aficionados, things are moving forward anyway. I just received samples of the aluminium profiles, anodized in black. Very nice!by M_Xeno - Delta Machines
I agree with DC42 : MDF is not stable enough for any mechanichal application. A new product of Portuguese origin, the VALCHROMAT, could be of interest to the 3D printing community. This product is moisture resistant, harder, denser, more stable, and more resistant to bending than MDF. As the product is coloured in the mass, architects and decorators are increasingly using it as a replacement foby M_Xeno - Mechanics

@etfrench Indeed, it is exactly the same idea. I didn't know Warner Berry's prior history. That's how great minds meet! I will now have to say that Zatsit's architecture lends itself particularly well to the implementation of Warner Berry's idea! I will make it my duty to indicate, wherever I have spread this idea that I thought it was mine, that Warner Berry had it before me.by M_Xeno - General
I published today, on Zatsit's Kickstarter page, in "News", a video where I show some tips related to the accessory attachment system, by three magnets. One of these tips concerns the creation of a hot chamber, to print certain difficult plastics in a heated environment (up to 130°C, if the power of the heating plate is sufficient). This feature is usually reserved for professional printers, veby M_Xeno - General

@o_lampe Imagine that I started by trying the Hylite on a machine with two linked polar arms, and also on a Scott-Russel mechanism, extremely light, and which only requires a single guide axis. These two mechanical formulas share the same limitation: Cartesian coordinates can only be checked, from a non-Cartesian kinematics, for a single point, which poses on the one hand mechanical adjustment pby M_Xeno - Delta Machines
@dc42 Thank you for your favourable opinion, which is all the more valuable because it comes from a respected expert! @All I would like to say that the price of the kit does not result from a trial balloon strategy, or whatever. Believe me, it's not just about throwing a Hylite plate at a CNC, and pressing the Go button. It is a high-precision process, with human supervision, and even modern maby M_Xeno - Delta Machines
Hi, o_lampe ! I am sure I have already written a response, but I must have forgotten to click on "Post"! Sorry....

Gimballed Flystruder This is available as an accessory, as part of the ongoing KickStarter campaign Zatsit on Kickstarter I would be curious to see this accessory adapted for contexts other than a delta printer: indeed, the reception device consists of two holes, and two spherical magnets.

Hi fruscus! Thanks for backing! You can certainly strip a Kossel delta to reinstall all the components on a Zatsit delta, since the mechanical architectures are comparable. You will certainly have a significant gain, because of Zatsit's mechanical accuracy, the ultra-light hot-end, and the powerful remote blower fan. In addition, if you also buy a Titan extruder, you can install it as a Flystrby M_Xeno - Delta Machines
Hi! Yes, the flystruder gimbal fits any delta, as long as you can install an elastic cord between the three carriages. The hot-end is also universal. You simply need to print (or otherwise create) a support that provides a vertical slot 2mm wide, >1.2mm deep, to a height of 16 to 18mm, and two symmetrical holes spaced 7.5mm apart, for M3 screws.
