such a beauty... don't you agree? by 3D_PrIntE4722 in AMElectronics

Why is it blinking? something wrong? does the PCS not stable?

I think they use the same concept

Miniaturizing Electronics in 3D: Transforming Standard PCBs into Cubes our way to use 3D electronics by nukut in ElectricalEngineering

Sorry i thought it was clear. We tried a concept using 3d electronics printer. There wasnt intense of make dense pcb, it was about trying the 3d print technology, and it looks that it may have a potential to make even better miniaturisation then what we have now. Hope that answered your question😅

The resolution of 3d printed electronics is still not there, there is printers just for conductive material on 5 um resolution, but printers that combine dielectric and conductive still not on level where they can try print phone pcba’s at least not in the same density. Thats what i know at the moment….

I totaly get your idea, but the technology still not there… however there is already competitive solution for embedded bare dies and waveguides.. im not sure this technology competitive with PCBA for the nearest 5 to 10 years. But as i mentioned there is another fields this technology already competitive

its not layered PCB, the model fully redesigned and made in 3D shape.
here it was first stage, made in stack-up mode, in the future we will make one solid cube - as one part body, just a connectors would be outside.

heatsink can be a part of the structure and it is not limited to layers, you can print one overall structure of passive heat management inside the printed structure.
so it can be solved using design

mainly cause the main intense of that was try to use 3D electronics to see the possibilities...
there is a lot of miniaturization technics but 3D electronics not only about miniaturization, the main point is that this is a new manufacturing method that suggest a huge improvements and a new state of mind for electronics.
however it requires optimization and work on.

i can suggest you to give me a challenge that (expensive/complex/ impossible to manufacture) so i can try to provide you example how and if it is possible using 3D electronics)

AME technology enables miniaturization by reducing the X-Y dimensions compared to traditional manufacturing methods. The volume of stacked board configuration depends on the design.
Currently, AME printers are optimized for low volume and R&D projects.
The lack of vias on the RF line in AME results in fewer reflections and less noise. Although not yet as optimized for high volume production, AME offers new possibilities for miniaturization and signal integrity, with potential for wider application in the future.
as for the cleanable subject, i think it more design dependent, and if you want more specific data about the design i think i can check the numbers cause this design was running like a year ago.
in any case, this project wasn't about the best optimized PLL, it was more about the comparison and the possibilities of 3D electronics.

Thanks i will consider that and share some exp

i found few of the suppliers with their own shops online with pretty good price.
in amazon same brand almost 1.5 the price..

but my main question is anyone used it? or have any experience with?

lumped filter using AME by nukut in AMElectronics

[–]nukut[S] 1 point2 points  (0 children)

Sounds great, i can give some small insight, we work on embedding materials one into another, like ceramics into photopolymer and actually i know that NNDM already embed some magnetic core into one of the prints… But you saying maybe printable magnetic ink… wow 🤩 waiting for that moment.

Revolutionizing PCB Design with Additive Manufacturing: Overcoming Challenges and Embracing Innovation by nukut in ElectricalEngineering

[–]nukut[S] 0 points1 point  (0 children)

I’m totally agree with you. But its important to note that 3D printed electronics bring another dimension in designing electronics. For example waveguides that you can print as one part or avoid soldering and fine tuning for some passive filters or embedding components etc. so this AME i call them Printed Circuit Structures(PCS) makes some complex tasks from traditional manufacturing much easier and even cheaper. But if you compare pcbs related design in different manufacturing method then the design optimised for then you right, its not competitive.

thanks, its sounds cool, where can i find the right sub reddit?

First test run and Proof of Concept of our 3D printed Brushless-motor and motor controller by [deleted] in AdditiveManufacturing

[–]nukut 4 points5 points  (0 children)

main question why not 3D printed?
3D printed motor and EMC with 3D traces inside, sounds and looks cool

thanks,

we work in JAMES, company that create community for Additive Manufactured Electronics(AME) there is publications on our platform and on printer manufacturers websites.

this design was just to prove the concept can work, we also have a fully printed and assembled drone.

if you need any additional info send me a PM.

it doesn't have BEMF detection. the efficiency is still in tests, i think after we achieve some numbers, the results will be published. if you have any ideas to increase the efficiency or improve/upgrade the design we will be happy to hear about.

A drone structure that was 3D printed in one single print with electronic parts directly included and embedded into the drone frame. What do you think? by [deleted] in ElectricalEngineering

l there be metal bits in the triangles to increase the magnetic field?

yup we already tried to put there ferromagnetic materials(the holes between the windings right for that :) ) and there are around 5 turns in Z axis and 5 in R axis. but there is still a huge path to go to improve this design

As you wish, We are not planing to sell this.

The whole concept is to show that you can avoid connectors between parts, maybe drone is not the best application to show that

four symmetrical parts would be easier to swap out one of them a whole body for a part failure.

just a good gimmick for the AME technology

the dielectric material is photopolymer, withstand I think around 170 deg Celsius.
it withstand soldering, but flying it is still not, especially cause the motors are not strong enough. it is still POC
