This channel showcases research and education activities by the Mechanosynthesis Group at the Massachusetts Institute of Technology (mechanosynthesis.mit.edu), The group is led by Prof. John Hart in the MIT Department of Mechanical Engineering (meche.mit.edu/people/index.html?id=719). Thanks for visiting!
in this day and age, needs to be an emphasis on material strength overall. Automation is great, but too much quality issues falling through the "cracks" --- get it? Ok bad joke.
Such an amazing presentation. I cant believe this came out 5 years ago. Definitely is living up to the facts that are displayed. So many good points that I wouldn't have thought about otherwise.
So many variables that affect quality and performance. $1,000 printers will replace $10,000 printers and $20,000 printers will replace $100,000 printers. Sooner than many realize. The biggest difference rigidity between machines and quality of extruder. Surprised there wasn’t any discussion about DLP or LCD resin printing. Both i can see dominating this market. We are already seeing 4k to 8k resolution quality prints on desktops
Several problems noted with the 3d printer devices shown 1) The components that make up the 3D printers are too big 2) The feed stock wire used in most wire feed machines is too thick 4) There is only one feed wire not multiple fine wire stock feeding into a given machine. 3) There are not enough print heads crammed into a small enough area Idea: 1) What if the feed stock could be significantly thinned 2) What if numerous micro print heads could protrude from a flat surface 3) What if that flat surface from which the micro-print head protruded could make minute shift like a pixel shifting false 4k projector 5) What if that same surface could also make large movements in the x, y and z planes 4) What if a ultra-mini heat source (for melting ultra thin feed stock) could be added externally or internally to each of the micro-print heads Would such a theoretical 3d printer print more dimensionally accurate 3d parts? Could such a 3d printer be made to print metal parts? Does current miniaturization technology exist that could be repurposed or used to create micro-print heads? Could Wire feed stock be created that was thin enough to feed said 3d printer? Could the printer somehow thin said wire further to meet specs for microscopic print heads?
Longyi super fine powder grinding machines advantages: 1. Powder from 48~4microns, fineness is adjustable 2. Built-in high efficiency classifier, no more investment cost for classifying system. 3. Smart PLC operation system, and integrated control system: 1 computer could operated max 6 machines, saving management cost. 4. No particle air pollution, more environment-friendly. 5. Compact structure to save factory space and lower foundation construction cost. For CaCO3 powder The whole grinding system including grinding, classifying, powder collector, fan, PLC cabinet, feeding conveyor and others, system power is 370Kw, the real working power is 296KW 1. D97=23um (600mesh) Output: 10tons/h Energy Consumption: 29.6Kw/Ton 2. D97=16um(800mesh) Output: 8tons/h Energy Consumption: 37Kw/Ton 3. D97=10um (1250mesh) Output: 4.5tons/h Energy Consumption: 65.7Kw/Ton 4. D97=6.5um(2000mesh) Output: 2.5tons/h Energy Consumption: 118.4Kw/Ton MP/Wechat/Whatsapp: +86 15105956429 Email:Samuel@lymill.com
Hi professor. I AM a material chemist from Brasil. Loving The classes for nanomanufecturing. Wish tô know, if you could send me The PDFs from The lecture. Thanks for sharing all this information
Dr. Hart, thanks for the excellent introduction to manufacturing. I have also enjoyed the additive mfg introduction. Are there other video lectures in your series?
Wow... Someone linked that video from 2017 to my 03min. 27sec Benchy print video and... 1. I remember I saw this years ago and I was completely stunned! 2. So nice to see that the future already happened in 2017!
