I think while they may only be advertised for 800w sustained power draw/output, these motors are probably capable of consuming much greater power and delivering that higher power output, but for only short durations.
@@AKAtheA technically you can over current and overvolt them until smoke starts appearing and shut it off. Let it cool down and it will still work. (not that you should)
@@johan1740 eh if you have enough cooling it should be fine, though i guess there is a point where the required cooling for the motor will be impossible to attain.
You should usually include a stator inside your EDF to straighten the flow. This stator will also provide back pressure on the intake fan providing additional stress levels. You might want to test this theory as well. I know you're not trying to make a functional EDF but rather test your printer. Additional forces on the fan blade may allow for better strength testing. Also this will allow the can to pressurize a little bit more testing the outer wall strengths as well. All in all well done, looks like an excellent little machine!
So from the design, the inside of the outer shell appears to still be hollow, but with structural supports. How do you get the un-sintered powder out of the the hollow? there doesnt appear to be any hole. And if you arent removing un-sintered internal powder, why not just sinter it all and make the shell solid?
Could be to do with the unsintered powder being less dense and therefore less heavy than sintered. But if weight saving is the aim then I would expect them to fully remove it as you said. The part doesn't look thick enough to need hollowing to reduce the energy in that area of the build either. Strange
Always advertise a bug as a feature. The powder inside helps to dampen the vibration and provide a fantastic inflight entertainment experience for the passengers.
@@wingnutzster This doesn't demonstrate anything. They should have measured the RPMs of the motor to demonstrate how strong it was. Telling us the power consumption of the electrical motor is useless.
Excellent practical application put to functionality test!! The propulsion output seems high and efficient. Well-designed stator guide vanes should impart a better air mass outlet flow and improved vortex control. However, your project seems very good and well done to you and your team!!!!
Hello Michael, the project is already over a year old and so far Andi has focussed on different projects (RC drones) - so no, currently we haven't planned that. But with all the new attention this video is getting maybe we will try something like that?
If this is gonna actually be used by modelers i would highly recommend fixed counter angle blades to help straightened exhaust flow. You can see the air flow is spinning as it exits. You could easily achieve higher efficiency with 5%-15% more thrust per watt. But overall an amazing project. Well done. I might try it out on my MSLA printer with a high polymer resin. Going to be experimenting with chopped carbon strand/multiwall carbon tube infused resin
Did you calculate the shape of the shroud and especially that of the stalling edge (the wavy shape at the end)? If yes, how so? If no, how did you determine it?
@Semper Fortis Its a Ducted Fan, like I said, a Turbine EXTRACTS energy from the gas flow. Your FAN is driven by an electric motor...Entirely different.
@Semper Fortis A turbine takes energy from *outside* the system and converts it into mechanical energy tu use into the system. (like how a water turbine converts the flow of water into mechanical energy and then sends it to an alternator to convert it into electrical energy) This does the opposite. It takes electrical energy from inside the system (the electrical energy from the battery) and converts it into mechanical energy and puts it out of the system as an airflow. A turbine takes energy from the outside. A fan puts energy outside. This is *clearly* a fan. I just saw that they even say it in the description of the video. They say it's an elelctric ducted fan. The title is just clickbaity.
@Semper Fortis Fan and turbine are two different things. There is no turbine in this EDF. ,,The title is correct .'' - As an former designer of turbine vane blades profiles for PW1000 series engines, I say NO.
Interesting printing technology. But what was the thought process of leaving the first version hollow in the first place? Wouldn't the hollow areas still be filled with the powder? Why not make hull a little bit thinner and solid instead of hollow?
RPMs and thrust loading along with weight of the fan component? (Watts alone doesn't tell entirely what stress is seen because of differences in motor types. Some will put that power towards the potential torque available, but will not see forces that will stress a component while mostly unloaded.)
The finish on this print is just absolutely awesome. Shame, that again it's a commercial products not really available (within financial reasons) to hobby users.
Thank you Kris. The Sintratec Kit that we offer is still the most affordable SLS system on the market and might be an option for you - but in general we agree, the technology is more aimed at mid-range industry rather than the hobby market unfortunately!
The Sintratec Kit is the most affordable Selective Laser Sintering system on the market, priced under 5000$ and available for home use. The Sintratec S2 system, on which the EDF was produced is more aimed at the industrial sector. Feel free to contact us via info@sintratec.com or visit sintratec.com/
Try making some 6 inch props and run them on some emax 1806 2280 KV motors. it’s a common, cheap, and quiet setup allot of builders use for light model aircraft. I’d love to see the results with such a material and how practical it would be to use in such a application.
It is a white smoke powder stored in a capsule - you can find a similar type here: www.regin.com/product/s102-45-sec-150-cu-ft-smoke-emitter-10-pk/ Best regards.
Would do a lot better if you print a stage after the fan like a vane in order to straigten the stream lines like the do in normal engines. You can see, that the flow has a lots of spinn. That is flow you loose

hmm, ive seen turbines printed trough fdm with much mure extreme shapes and also quite larger, still impressive but i think sls can do way more interesting and larger turbines than this
A lot of different applications for this should be able to make the same thing for are intake for an automobile because you're seems to be more robust than the ones they sell on eBay how much thrust are you pushing
@@CONCEPTCOLABSYSTEMSwe do not have it in our shop currently - but if you shoot us a mail maybe we can produce one and sell it to you. Just ask our sales stuff via sales@sintratec.com - thank you :)
That material looks like what r/c tires are made off. I mean its a creative test, i just dont see the use of making a foam edf. Even made out of steel for a bench model, edf motors are so inefficient its like trying develop a better square wheel material while ignoring the limitations of the very shape.
My humble opinion, you should design a 4 stator blade motor support instead of 3stator motor support for strength as the motor is quite heavy and the stator need to bear the motor weight not only in gentle landing but hard landing without breaking.
Hey there, sorry again for the delay. Andi didn't know what they were, we just have them in our workshop for testing airflow. But apparantly it's a white smoke powder stored in a capsule - you can find a similar type here (we bought different ones in Switzerland but they should be pretty much the same): www.regin.com/product/s102-45-sec-150-cu-ft-smoke-emitter-10-pk/ Best regards.

"EDF turbine"? You'll need a electrically driven fan to power the turbine to power the fan, which then defeats the purpose of powering the fan electrically in the first place. Please fix your title. How much does the whole assembly weigh?
Цена 150 евро за килограмм пластиковой пыли это уже большой прогресс по сравнению с другими производителями. Я видел такие банки и по 500-700 евро. При этом килограмм полиамида стоит 5 баксов... С другой стороны мой FDM принтер печатает со слоем в 0,6 не хуже чем этот из пудры. На мой взгляд эта технология слишком переоценена и сопряжена с массой трудностей, таких как постобработка деталей. А хотят денег за нее, будто бы этот принтер печатает металлом. Мне, если честно не совсем понятна экономическая ниша этой "чудо техники". Если говорить за производство прототипов, современные слайсеры делают чудеса и на принтере за 500 долларов можно напечатать то же самое, что вы напечатали на лазерном. Если говорить о производстве изделий мелкой серией с заданными прочностными параметрами, то цена как материала, так и самого принтера заоблачная. У нас в стране можно кое где купить квартиру в городе по цене такого одного принтера. Только не обижайтесь на критику, я потенциальный покупатель таких принтеров, но я не вижу к сожалению ниши для него на своем производстве, несмотря на то, что я изделия массой в 100 граммов из полиамида продаю по цене в 50 долларов. Все равно печатать их на 3д принтере не выгодно.
premièrement il est anglais, donc le commentaire ne sera jamais lu, deuxièmement, rien ne t'empèche de l'imprimer avec la matière que tu veux et la faire tourner moins vite sans risquer d’endommager la structure

They dont remove it. And it is stupid to not sinter it all. The reason why they didnt do that, is because of printing time.
Always advertise a bug as a feature. The powder inside helps to dampen the vibration and provide a fantastic inflight entertainment experience for the passengers.
Now smooth the inner surface and blades and run it again.
Should see a massive increase in air flow velocities.
What was your effective lift force?
A small bit of massive😂
@Guybrush Threepwood close to nothing
Lol 0.1% massive
I think the goal here was to show the strength and feasibility of the SLS print and not to create the worlds most efficient edf
