- Try clicking on the various channels to see videos posted to that channel - if you're into music you can click the Music channel to get more music sifts - go on and explore! Use the "hotness" when you have opened the channel link to get videos that have gotten a lot of votes, or use "newness" to have a look at the new sifts.

  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

Engineer Guy - Bottom Up 3D Printer

submitted by Fantomas

6 years 8 months 3 weeks ago

YT: In this video Bill explains some of the engineering principles underlying the design of a DLP (digital light processing) 3D Printer. The printer featured is an Ember printer, manufactured originally by Autodesk, but now an open source project.

As the former owner of a DLP rear projection TV, I can say that the Ti DLP chips will not last 11 years before some of the tiny mirror elements begin to fail (on a TV, it would show up as a stuck-on white pixel).

Moving this video to Fantomas's personal queue. It failed to receive enough votes to get sifted up to the front page within 2 days.
