Identifying components used in a system

AI Thread Summary
The discussion centers on a university project focused on material deposition systems, specifically analyzing a video showcasing impressive speed and precision. Participants speculate on the technology used, with one suggesting that it resembles FDM 3D printing, where a heated nozzle extrudes filament. However, concerns are raised about the cleanliness of the output and the properties of hot glue, leading to alternative theories. One idea proposes the use of a high-pressure reservoir with a fast rotary valve to achieve the desired results. The conversation highlights the need for further insights into the specific mechanisms behind the system's performance.

Hi,

I am working on a university project looking at material deposition systems. i came across a 30 second video on Youtube and i would be really interested to know how this product is achieving the speed and precision shown in the video. If anybody has any suggestions about the technology used that would be great



Many thanks

Are you aware how FDM 3d printing works?

I'd guess it's just like that i.e. a reel of hot glue filament is pushed through a hot nozzle ('hot head').

To improve speed and precision you increase the power and control system of both the heated nozzle and the stepper motor that pushes the filament.
 
Good thought, Billy, but it makes me wonder. I've never personally seen hot glue come out that cleanly, with no filaments dragging behind. Also, I'm pretty sure that the purpose of the thing is to leave soft glue, which hot glue would not remain. The thing reminds me for all the world of those air-powered BB machine guns in the shooting galleries at a fair. Could it just be a high-pressure reservoir of liquid glue feeding through a very fast rotary valve?

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
