Krylin has spent a year designing Positron, which has already caused a stir by being a filament printer that deposits polymer underneath the print bed, so the object hangs down as it prints – which brings all the moving mass down to bench level, allowing high print speeds.
And despite folding into a ~200 x 200 x 75mm space – the prototype is carried around in a printer filament box – version 3 of the prototype will print objects up to 180 x 185 x 180mm.
This is not the first ‘upside-down’ printer, and Krylin credits the giants on who’s sholders he stood, but it is a jewel-like example of the concept that prints extremely well – making it all the more remarkable that its designer has given it to the world – including for commercial explitation.
Take a look at this YouTube video to see version 3 of Krylin’s Positron in action, and to see the history of its development. (Image above copied from the YouTube video)
