Cool use of a smart phone https://www.kickstarter.com/projects/olo3d/olo-the-first-ever-smartphone-3d-printer
Just realize that getting a call will interrupt your print.
Whoa, that’s something one does not want to have happen, especially at the cost of resins for this type of printing.
They reached the US$80,000 goal in under 45 minutes and had an error on the project campaign page. One could get two printers and resin for $99 plus shipping. It was a typo, but once discovered, the “sold out” sign appeared although the people who pledged that item will get it, per the campaign owner.
I hope it doesn’t go the way of the iBox Nano printer!
Lol make sure your in airplane mode
Will wait for tablet size. Phone build volume is a bit limiting. And I am curious about how new 3D printing users will fight with successful printing ratio of resin technology and with some home chemistry.) 
@Daniel_Joyce unless you put it in inflight mode. but this doesnt stop other things like alert broadcasts like storm warnings and amber alerts.
There is something like Do no disturb mode. (On new phones. I use it also on tablet.) You can choose which (if any) app can make allert, incl. calls.
And that still doesn’t prevent notification pop ups
