What is Binder Jet 3D Printing?

As one of the seven families of additive manufacturing technologies, binder jetting is a 3D printing process that uses a liquid binding agent deposited onto powdered material to create a part’s geometry. It is mostly applied with metals, but can also be used to create objects from ceramic, sand and other materials available in a powder format. In the case of metals and ceramics, binder jet parts are considered “green” until they are debound and sintered to consolidate the material. But because the jetting step takes place at room temperature and sintering happens all at once, these parts can avoid many of the heat-related challenges faced in powder bed fusion. Pete Zelinski and Stephanie Hendrixson discuss how binder jetting works, compatible materials, postprocessing considerations, applications and more in this video.

Great info as usual and looked pretty unbiased which from humble perspective is great to see! It also a preferred option I am yet to have an example from but should make perfect product for production, shame is no demand except my own🙁 alas. 👍👍🏾👍

Amazing, learnt something new today and just in time. Will do more research on this method of 3D printing.

super helpful/to the point video. thank you!

Would really like, if there was a home shop sand binder jetting setup available. The technology shouldn't be that expensive. It would be so much better than lost PLA.

Binder jetting originally was and is still used in digital textile and flex banner printing. Application change. Tech was modified. Interesting.

Insteads of Ejecting CMYK, its binder now
Instead of material such as textile orinting, its now sand and metal powders.

I like the videos but you should do a deep dive on the specifics

Try Fujifilm Dimatix, SG1024 and Spectra Printhead modules used in printers manufactured by Exone and Desktop metal.

They use CPLD and FPGA based firing and head control boards. Mostly Binary Single Pulse. No or Some type of control of the Binder Drops.

Textile uses Multi Pulse waveforms and thats why you get different shades of colors.

1:20 I think these are student-proposed high-efficiency CPU cooling blocks

Is It possibile to realize components working at High temperatures, , Just like heat exchangers?

Imagine if you lived on the coast and you just went to the beach to pick up 3D printer filament

I love your content. It would be nice if you talk to each other instead of staring weirdly into the camera. But that is my personal opinion😊
