Continuous Liquid Interface Production (CLIP) 3D printing

[benny_r_t_2]

I don't know if this is old news.   I just read about it today and thought LTT would think it interesting as I do.  It is a new twist on the 3D printing.  Instead of building from a base and stacking on top via stream of plastic, the "CLIP" base is inverted and builds upside down from a liquid pool of resin that is cured via light patterns and oxygen.  The links below I think explain it better.  Super expensive but neat tech and perhaps a future direction for 3D printing.  Currently, because it is so expensive, they have a subscription price model rather than outright purchasing a printer.

 

 

 

Continuous Liquid Interface Production

"CLIP is a photochemical process that carefully balances light and oxygen to rapidly produce parts. It works by projecting light through an oxygen-permeable window into a reservoir of UV-curable resin. As a sequence of UV images are projected, the part solidifies and the build platform rises."

Sort of old news, very interesting tech. Annoyed that they just have one talking point basically because they don't want anyone else to discover how they control their prints

I added a bloomberg article so it wouldn't be just the company tooting their own horn.  It is neat.  I spent (wasted?) the last hour talking about 3D printers with my co-worker after reading about this.

godamit people. we dont need faster prints right now. we need them cheaper.

Old But Interesting. I enjoy reading about these innovations nonetheless.

I don't think this printer's only claim to fame is speed, but I think instead it's the resolution and quality of the printing.

Quite interesting.

I then discovered that Walt Disney company has a similar idea and Patent involving a liquid resin and UV light for 3D printing.

sorry for the long URL.  That link leads to a 17 pg patent document with drawings.  It is unclear to me from the Disney patent if the printing is performed layer by layer or all at once.  I would think it would have to be layer by layer but the drawings imply all at once?

They're trying to

Maybe not the printers themselves, but the printing process
