It must be a very strong ray of UV that they shine through the teflon AF 2400 film to have a oxygen permeable film that can stay straight with epoxy on it. perhaps the oxygen zone is under pressure and the teflon is only 1mm thin. The balance of that probably makes a size limitation on the prints. There is a great printer that can print giant parts in a vat of epoxy by shining at the top layer, and indeed it works in steps as it sweeps over the top layer, whereas this has infinite z resolution. / framerate z resolution. | |

Normal SLA is done iteratively, debonding the part from the window and applying new resin for each layer between exposures. By using this "dead zone", the part doesn't stick to the window and new resin is drawn under it as it is raised, allowing continuous exposure. And they do use a projector, with a DLP chip. | |
| Mar 20, 2015 at 10:07 | comment | added | bandybabboon | There is an article on the website slashdot with probably alot of conversations regarding this news story... just found a page that said: With a free radical system, polymerization stops as soon as the light is eliminated. Free radical systems are also subject to oxygen inhibition, which means that oxygen in the air prevents the molecules at the surface from polymerizing, leaving a wet or tacky surface.... here is the full information - its freely available. justpaste.it/k1tn | |

projection of slice masks in irradiation from the bottom addressed.

| Mar 20, 2015 at 3:39 | comment | added | bandybabboon | there is an oxygen permeable layer: gizmag.com/clip-carbon3d-3d-printing/36606/pictures#4 The process relies on the right balance of light, which triggers curing, and oxygen, which inhibits it | |
| Mar 19, 2015 at 20:22 | comment | added | Klaus-Dieter Warzecha | @ufomorace there's a misunderstanding. there is no oxygen layer inside the resin, there's just air on the top of the basin. | |
| Mar 19, 2015 at 20:19 | comment | added | bandybabboon | I am curious about how they manage to focus the UV light into a point rather tan a line, and what the oxygen layer is inside the epoxy, if they inject oxygen through the base in some way. | |
| Mar 19, 2015 at 20:17 | comment | added | bandybabboon | AKA = i am also immeasurably annoyed by this Dreise "novelty" . Yes Georg it seems that the media is promoting this form of 3d printer as new. perhaps it's the first one that can print as fast and that has been filmed printing in one single movement? | |
